Description
Technical field
The invention belongs to a kind of oil field chemical, particularly to a kind of oilfield additive.
Background technology
Oilfield additive includes degreaser, water cleaning agent, reverse-phase emulsifier, sewage clarifying agent, demulsifier, Ca, Mg and Fe ion remaval agent.During tertiary oil recovery, along with polymer flooding and poly-table drive stimulation work technology being widely popularized in oil field, the most incident produced water treatment problem also becomes to be becoming increasingly acute, tradition oil-polluted water degreaser is usually inorganic polymeric aluminum class flocculant, this kind of flocculant is to general oil-polluted water, treatment effect is preferable, but to the sewage containing polymer, then can not reach intended and process requirement.Inorganic poly-aluminum is used to have the unfavorable factor of 3 aspects: (1) introduces high price inorganic ions, adds the corrosion to equipment of the water system, can cause pipeline leakage, the seepage of the connectors such as valve, directly affect production time serious.(2) containing substantial amounts of water in the isolated oil of water station, this part oil will come back to petrol station and be dehydrated.Owing to introducing high-valence cationic, adding the electric conductivity of system, easily cause two high-pressure polar plates of electric dehydrator to puncture, cannot set up high voltage electric field, it is properly functioning that impact produces.(3) for the sewage containing polymer, polymeric aluminum class flocculant and polymer reaction, generate the big floc sedimentation of sticky shape, the defecator of sewage disposal causes Severe blockage, pollute filtrate, reduce production efficiency.Due to the particularity of bearing sewage for ternary combination flooding in oil, original water treatment technology and water treatment agent can not meet the most far away the requirement that water processes.Oil field chemical, in a broad sense, mean each lamp chemicals in all technical processs such as oil exploration, drilling, collection be defeated, mainly include mineral products (such as removing soil etc.), general chemistry product (such as various bronsted lowry acids and bases bronsted lowries etc.), natural prodcuts (such as starch), inorganic product (such as zinc carbonate) and special (fine chemistry industry) product (such as polymer and surfactant etc.).Refer in oil, the probing of natural gas, adopt defeated, water treatment and improve the analog assistant used in the process of recovery ratio, it various in style, major part belongs to water-soluble polymer (such as plant gum, polyacrylamide, cellulose and biopolymer) and surfactant (petroleum sulfonate, alcohol radical or alkyl phenol base oxethyl ether).Since nearly more than ten years, China's oilfield chemical technology quickly grows, and defines broader oil field chemical market.China's new discovery oilfield reserve is limited, and old filed is taped the latent power arduous task, especially for China's oil field feature, strengthens In Oil Field Exploration And Development, improves oil recovery rate, strengthens environmental conservation, need the most novel, efficient, oligosaprobic oil field chemical drops.The chemical displacement of reservoir oil is divided into: 1. polymer water drive.Soluble in water for a small amount of thickening agent (such as partially hydrolyzed polyacrylamide (PHPA) or biopolymer), increase the viscosity of water, improve the water fingering when injecting, improve oil recovery factor.Surfactant slug is the microemulsion being made into activity promotor alcohol by petroleum sulfonate or synthesising sulfonate, and it has ultralow interfacial tension, and (< 10-8N/cm, it is possible to by the mother oil displacement in capillary tube out improves oil recovery factor.Maximum difficulty is intended to loss when overcoming surfactant to flow in oil reservoir (adsorb, trap, precipitate).3. caustic waterflooding, reacts the active component that Caustic soda water injects in oil reservoir, with crude oil, forms emulsion, to improve oil recovery factor.
Through China's publication retrieval, do not find the scheme identical with present patent application.
Summary of the invention:
It is an object of the invention to；Propose a kind of aluminum sulfate and strengthen stratum protection agent.
The aluminum sulfate of the present invention strengthens stratum protection agent, it is characterized in that: by weight, by two butanoic acid di-sec-octyl sodium sulfonate 10-30 parts, sodium bicarbonate 35～40 parts, gluconic acid lactone 18～23 parts, quebracho 215-260 part, dioctyl succinate sodium sulfate 10-30 part, , methyl sodiosul foaliphatate 10-30 part, brown coal 120-150 part, Colophonium 24-30 part, paraformaldehyde 10-20 part, sodium hydroxide 12-15 part, carboxymethyl cellulose 10～20 parts, water 130-150 part forms, whole materials are mixed, at 75-120 DEG C, stirring reaction 2-3 hour, obtain product.
Compared with prior art it provides the benefit that the present invention: has raw material and is easy to get, low cost, environmental protection, advantage easy to use, effective.
