Description

The claimed invention "Mixture for the production of building material" relates to building materials made from industrial waste and used in the construction of road bases inside fishing grounds, roads, embankment of the bases of well sites, as well as grounds for landfills, etc.

A known mixture for obtaining building material (see RF patent for the invention No. 2399440, IPC B09B 3/00, publ. 09/20/2010), including drill cuttings, mineral additives, accelerators, desiccants and hardeners, and it contains loam as a mineral additive , sand, sand and clay fraction, calcium chloride and / or sodium as an accelerator, at least one of peat, mineral wool, slag, cellulose fiber, silica gel, foam insulation as a hardener, cement and / or bitumen, and optionally carboxymethyls cellulose - CMC and / or polyvinyl acetate - PVA and spent technological solution with a density of 1.08-1.86 t / m ³ and wastewater boring water resulting from drilling operations

A disadvantage of the known solution is the high cost.

This drawback is due to large quantities of imported material.

Also known is the construction material “Burolit” (see RF patent for the invention No. 2303011, IPC C04B 28/04, published 2007.07.20), including drill cuttings with a density of 1.3 to 1.8 kg / dm ³ , cement in an amount of 10 -20% of the volume of drill cuttings and urea-formaldehyde foam with a density of 10-30 kg / m ³ in the amount of 10-25% of the volume of drill cuttings and additionally a mineral filler with a particle size of from 2.7 to 3.1 mm, selected from the group containing sand and crushed granite, in an amount of 10-20% of the volume of drill cuttings, in addition, it additionally contains calcium chloride th in the amount of 2.0% by weight of drill cuttings containing oil products, water, shale, highly plastic clays, sand, siltstones, barite, carbonates, saipan, carboxymethyl cellulose, nitrilotrimethylphosphonic acid, sideril, tribos, graphite, clay powder, heavy metals mechanical impurities.

A disadvantage of the known building material is the high cost, low frost resistance and strength, especially in areas of flooding, since this building material is eroded by water and migrates into the environment.

This disadvantage is due to low operational capabilities and at the same time large quantities of imported materials such as cement, urea-formaldehyde foam, calcium chloride and mineral filler containing crushed granite, with a particle size of from 2.7 to 3.1 mm.

Of the closest known to the claimed is the composite building material adopted as a prototype based on drilling waste, urea-formaldehyde foam in the form of crumbs or pre-prepared foamed and cured formaldehyde resin in an amount of 10 to 25% of the volume of drilling waste, a mineral filler with a particle size from 2.7 to 3.1 mm in an amount of from 10 to 20% of the volume of drilling waste, selected from the group containing sand and / or crushed granite, an accelerator in an amount of from 2.0 to 5.0% of the volume of drill waste in the form of calcium-containing additives, which use calcium chloride and / or quicklime, and / or sodium-containing additives, which use table salt and / or soda ash, hardener in an amount of from 1.0 to 30.0% of the volume of drilling waste which is used as calcined drilling waste and / or gypsum and alabaster and / or cement and alabaster and / or cement and gypsum, and additionally a desiccant is introduced in an amount of 1 to 30% of the volume of drilling waste used as peat, formiro Atelier of the structure, which uses double superphosphate and urea resin based on a volume ratio of 1: 1 in an amount of from 5.0 to 6.0% of the volume of drilling waste, and / or additionally use a bacteriological preparation consisting of hydrocarbon-oxidizing bacteria in the form consortium of microorganisms ARTHROBACTER OXYDANS and PSEUDOMONAS PUTIDA in an amount of from 0.1 to 3% of the volume of drilling waste, moreover, drilling waste with a density of 1.3 to 1.8 kg / dm ^{3 is} used as drilling waste (see RF patent No. 2408626, IPC C08L 61/00, publ. 02/10/2010).

A disadvantage of the known building material is the high cost, low operational capabilities and frost resistance.

This drawback is caused by large quantities of imported materials, such as cement, urea-formaldehyde foam, calcium chloride and a mineral filler containing crushed granite with a particle size of from 2.7 to 3.1 mm, as well as an expensive bacteriological preparation consisting of hydrocarbon-oxidizing bacteria, in the form consortium of microorganisms ARTHROBACTER OXYDANS and PSEUDOMONAS PUTIDA.

The technical result of the claimed invention is to reduce the cost while increasing the protection of the hardener, which is used as cement and calcined drill waste, and / or gypsum, according to the invention it further includes a sorbent, in an amount up to 25.0% of the volume of drilling waste, as which uses penoizol and / or netrosorbolite and / or sorbolite and / or ashes, is used as a mineral filler, heat-treated proppant in an amount of up to 50.0% of the volume of drilling waste, and / or sand and / or natural incoherent soils in an amount of up to 65.0% of the volume of drilling waste, and at least one of: burnt drilling waste in the form of heat treated sludge in an amount of up to 20% of the volume of drilling waste and / or cement in an amount of from 5% to 20% of the volume of drilling waste and / or, calcium containing an additive in an amount of up to 20% of the volume of drilling waste, and / or glass sodium liquid in an amount of up to 15.0% of the volume of drilling waste and / or gypsum in an amount up to 30% of the volume of drilling waste, moreover, as a shaper I structure, use a mixture of urea resin and soda ash in equal weight parts, in an amount up to 6% of the volume of drilling waste, in addition, the mixture contains a desiccant, which uses peat in an amount of up to 35% of the volume of drilling waste, and as Calcium-containing additives use quicklime in an amount of up to 25% of the volume of drilling waste.

Between the distinguishing features and the achieved technical result, there is the following causal relationship.

Unlike analogues and prototype, the inclusion in the mixture of sorbents, in an amount up to 25.0%, such as sorbitol, netrosorbolite, ash according to GOST 2581891, as well as penoizol, according to TU 2254-001-44581572-98, which allow moisture to be sorbed and pollutants, in particular petroleum products, and provide better thickening of the mixture, it should be noted that ashes are also used to bind excess water and as a hardener to replace part of the cement, which reduces the cost of the claimed mixture. The use of mineral filler in the form of sand and / or natural incoherent soils in an amount of up to 65.0% of the volume of drilling waste and proppant thermally treated up to 50.0% of the volume of drilling waste, which is thermally treated after use, and which not only ceases to be waste after hydraulic fracturing, it also replaces part of the sand, improves the quality of the resulting mixture, and partially uses local cheap components, such as sand and / or natural incoherent soils, as a mineral filler mixtures for the production of building material, including together with proppant, eliminates the expensive transportation costs for delivering these constituent components to the place of receipt of the mixture for the production of building material, which significantly reduces the cost of the mixture and building material obtained from it, while expanding the raw material base of natural mineral raw materials when disposing of waste from drilling, and at the same time saves expensive natural resources brought in from a large number from afar, For example, such as granite crumb to the prototype object. The use of fired drilling waste as a hardener in the form of heat treated sludge in an amount of up to 20% of the volume of drilling waste eliminates environmental clogging with waste products containing petroleum products, since the fluidity of the feedstock is eliminated, and the drill cuttings after heat treatment turn into an inert composite material that binds in its structure pollutants, excluding their migration into the environment, and this increases environmental protection, improves the ecological situation on erritoriyah fishing regions. The use of cement as a part of the hardener also in an amount of from 5% to 20% of the volume of drilling waste and / or liquid sodium glass in an amount of up to 15.0% of the volume of drilling waste and / or alabaster gypsum) in an amount of up to 30% of the volume drilling waste and / or calcium-containing additives, which use ground quicklime in an amount of up to 25.0% of the volume of drilling waste, bind pollutants in their structure, excluding their migration to the natural environment, which also improves environmental protection, improves ecologists eskuyu situation in territories field regions, wherein, when applying plaster, lime plaster and which are also used for the sorption of toxins and excess water binding, a large amount of heat, i.e., significantly increases the frost resistance of the inventive mixture to (minus 50 ° C). The mixture of urea resin and soda ash calcined in equal weight parts in an amount up to 6% of the volume of drilling waste, which is a good binder, not only forms the structure of the inventive mixture, but also, in turn, improves the frost resistance of the resulting mixture. The desiccant included in the composition of the inventive mixture, which uses sorbing moisture and significantly reduces cement consumption of peat in an amount of up to 35% of the volume of drilling waste, also gives an additional technical result, namely, the possibility of reclamation of oil-contaminated lands or lands occupied by sludge pits due to the fact that peat, having an acidic characteristic, neutralizes the alkaline environment of drilling waste, and the microflora contained in peat contributes to the decomposition of oil hydrocarbons and heavy metals in sedentary compounds. The reduction in the cost of the mixture due to peat is also ensured because peat in the oil and gas regions of Siberia is local and not imported material, due to the abundance of peat bogs. Neutralization of drilling waste of wells belonging to hazard class III-IV with the production of environmentally friendly material belonging to class IV or V in accordance with Order of the Ministry of Natural Resources of Russia No. 511 of July 15, 2001 is carried out by binding and neutralizing toxicants in the structure of the consolidated material and eliminating their migratory activity. The claimed mixture according to GOST 25100 relates to industrial soils (natural soils, altered or displaced as a result of human activities, and anthropogenic formations), and is a type of processed materials in accordance with GOST 23558 (artificial material obtained by mixing soil, sand with cement or other inorganic binder and water). In the aggregate of features, the mixture for producing building material using the components reflected in the claims as a percentage of drilling waste allows to determine not only the receipt of the product, but also to achieve a technical result, i.e. to increase the frost resistance of the obtained product, as well as to increase environmental protection, to save natural resources, to reduce the cost of the building material obtained from the inventive mixture that binds substances polluting the environment in its structure, eliminating their migration into the natural environment. The possibility of obtaining cheap building material with a balanced composition containing mineral components allows it to be used in the construction of road foundations and technological infield sites, embankments, as well as for filling pits, quarries, sludge pits, strengthening road slopes, etc., since storage of such building material does not require technological difficulties, but only eliminates the possibility of environmental pollution, i.e. all this as a whole simultaneously utilizes waste from drilling wells, and also improves environmental protection, improves the ecological situation and makes it possible to transport the resulting mixture for building material, at various distances, including within the fishing region.

The composition of drill cuttings depends on the oil field, in this example we used drill cuttings with a density of 1.43 kg / dm ³ , the following composition: oil products - about 1.4 wt.%, Shale - about 15.34 wt.% Highly plastic clay - about 31.15 wt.%, Sand - about 13.3 wt.%, Siltstone - about 6.5 wt.%, Barite - about 0.85 wt.%, Carbonates - about 0.5 wt.%, Saipan - colo 0.13 wt.% (Trade name of the substance), sideril - about 0.07 wt.% (Trade name of the substance), CMC - about 0.05 wt.% - carboxymethyl cellulose, nitrilotrimethylphosphonic acid - about 0.024 wt.%, Tribos - about 0.07 wt.% (trade name of the substance), graphite - about 0.12 wt.%, clay powder - about 1.25 wt.%, heavy metals - about 2.23 wt.%, mechanical impurities - about 0 , 51 wt.%, Water - the rest (about 21.15 wt.%). During the heat treatment (firing) of drill cuttings used as fired drill waste, the harmful components of drill cuttings, including oil and oil products, were neutralized. The process of firing drill waste takes much longer than the process of heat treatment (firing) of drill cuttings, therefore, heat treated drill cuttings are used as fired drill waste, and the resulting heat treated (fired) drill cuttings used as fired drill waste acquires the properties of a neutral material and is used as a hardener. To obtain the claimed mixture, drilling waste generated as a result of drilling operations with a density of 1.36 kg / dm ^{3 was} disposed of in a certain volume, filling the mixer, into which mineral filler was also filled, which was used as local building materials, in particular sand in 60.0% of the volume of drilling waste, as well as thermally treated proppant, in the amount of 25.0% of the volume of drilling waste, at the same time, the former was added using a mixture of urea resin, we produce by industry according to GOST 14231-78, and soda ash in equal weight parts 1: 1 in the amount of 4.92% of the volume of drilling waste, which was also used as a hardener, as well as a desiccant, which was used peat from local peat bogs in an amount of 30, 0% of the volume of drilling waste, contributing, at the same time, soil remediation and reducing the amount of cement used. A sorbent was also poured into the mixer in an amount of 24.0% of the volume of drilling waste, which was used, in equal parts by weight, sorbolite, netrosorbolite and an industrial compound called Penoizol according to TU 2254-001-44581572-98, which allows you to sorb moisture and pollutants, in particular petroleum products, and provides better thickening of the mixture. As a hardener, burnt drilling waste was poured into the mixer in the form of heat treated slurry in an amount of 12.0% of the volume of drilling waste, cement grade M 400 D20, which allows its use at temperatures from -30 ° C (GOST 22266-94) and leads to thickening the mixture, binding the components of drilling waste, moreover, cement was added in an amount of 10% of the volume of drilling waste, a calcium-containing additive, which was used to simultaneously increase the frost resistance of the mixture to (-50 ° C) ground quicklime, in an amount of 15.0% of the volume drilling waste, sodium water glass in an amount of 8.50% by volume of the drilling waste. For 10 minutes, the mixture was mixed in a mixer until a homogeneous mass was obtained, uniformity was determined visually. Thus, a uniform, color and composition, loose, frost-resistant, non-combustible material was obtained from drilling waste with mineral additives, which, when mixed in the stated proportions of the solid phase with the above components at the selected sequence and disposal mode, provide, in combination of features, the formation of a strength structure with the receipt, in the future, of an inert building material with improved quality and durability and excluding the migration of waste into the environment, with building material that meets the standards, which can be used in road construction and arrangement of cluster sites. The hardening of the mixture occurs during its preparation at the place of work. The resulting mixture refers to technogenic soils (natural soils, altered or displaced as a result of human activities, and anthropogenic formations), which are a type of processed materials in accordance with GOST 23558 (artificial material obtained by mixing soil, sand with cement or other inorganic binders and water). The building material obtained from the mixture is frost-resistant, durable and non-combustible and neutralizes well drilling waste by binding and neutralizing toxicants in the structure of the consolidated material and eliminating their migration activity. The maximum design strength of the mixture is achieved at the design age of 28 days. Obtaining and storing the inventive mixture for obtaining building material does not cause technological difficulties and, at the same time, utilizes waste from drilling wells, and also improves environmental protection, improves the environmental situation and makes it possible to transport this building material to various distances within the fishing region. The materials used for the manufacture of the inventive mixture meet the requirements of the applicable regulatory documents that apply to them and ensure that the mixture receives the specified technical and environmental characteristics.
