Abstract
The present invention relates to a kind of composition of displacement of reservoir oil Surfactant Used in Viscoelastic Fracturing Fluids, and mainly solving surfactant in current production technology, oil displacement efficiency is poor in LOW PERMEABILITY RESERVOIR in high temperature as oil displacement agent, simultaneously because containing alkali, huge injury is brought to stratum and oil well.By using the composition for displacement of reservoir oil Surfactant Used in Viscoelastic Fracturing Fluids, including amphoteric surfactant and acylate in formula shown in (I)；The acylate in formula at least one of (II)；R1Selected from C8~C29Alkyl, any one in alkenyl, the R2And R3It is independently chosen from C1~C5Alkylidene, any one in hydroxyl substituted alkylene, any one of X in carboxylate radical, sulfonate radical, the molar ratio of the amphoteric surfactant and acylate is 1：0.01~1：100 technical solution, preferably resolves the technical problem, available in the displacement of reservoir oil production in oil field.
Description
Technical field
The present invention relates to synthesis of the displacement of reservoir oil by the use of the composition of Surfactant Used in Viscoelastic Fracturing Fluids and the composition to be used as the displacement of reservoir oil
The application of agent.
Background technology
With increasing rapidly for national economy, domestic petroleum disparities between supply and demand become increasingly conspicuous, and are mainly shown as petroleum resources phase
It is relatively low that the growth of demand, the recovery percent of reserves ratio of crude oil are not caught up with to poorer, oil exploration and development and proved reserves.To alleviate
China's oil scarcity of resources, reduce crude output notch, ensure China's oil safety, it is necessary to which one of important measures taken are exactly
Increase substantially the recovery ratio of crude oil in China.For example, the average recovery ratio of Sinopec is only 28% at present, still have more than
70% petroleum resources fail to obtain effective exploitation utilization, cause a large amount of remaining reserves to be retained in underground.How further to tap the latent power
Synergy, carry out tertiary oil recovery, it has also become one of problem urgently to be resolved hurrily.
In tertiary oil recovery technology, chemical flooding is main attack technology and the direction that recovery ratio is improved in China, including caustic waterflooding, table
Face surfactant flooding (micella drives and microemulsion drives), polymer flooding and combination flooding.In these chemical flooding technologies, all it be unable to do without efficient
Surfactant, by reduce oil water interfacial tension to ultra low degree (be less than 10-2MN/m residual oil flowing) is made to be carried to reach
The purpose of high oil recovery factor.Surfactant oil displacement uses Recompounded multielement system mostly at present, while comprising non-ionic
Surfactant and ionic surfactant, are additionally added the auxiliary agents such as alkali and alcohol in part formulation.Such as patent CN101024764A
A kind of surfactant of oil-field thick-oil well is provided, which is by water, piece alkali, ethanol, oleic acid, alkyl phenol polyoxy second
Alkene ether, sodium dodecyl benzenylsulfonate composition.For another example patent CN1394935 has invented a kind of chemical oil displacement agent, it mainly includes pungent
Base benzene sulfonic acid receives the clean property agent of anionic surface, surfactant adjuvant, surfactant synergist, surface active agent solubilization agent.
This oil displacement agent can significantly reduce the structural viscosity of viscous crude, while can reduce oil water interfacial tension, so as to improve oil recovering
Rate.However, above-mentioned surface active agent for tertiary oil recovery still suffers from more problem, the salt resistant character of anion surfactant compared with
Difference, nonionic surfactant temperature is sensitive, easily separates out, should not largely use under high temperature.For this reason, people started it is cloudy-non-
The research of ionic surface active agent, will two kinds of non-ionic groups and anionic group of different nature designs on same surface
In active agent molecule, the advantages of making it have anion and nonionic surfactant concurrently, have complementary advantages, and there is excellent heatproof to resist
Salt performance, shows good application prospect.Gemini surface active agent has the special construction for being different from conventional surfactant,
It is assigned with a series of uniquenesses such as ultralow interfacial tension, low critical micelle concentration, low Krafft points and excellent wetabilitys
Property, also result in the great interest of people.However, the Gemini surface active agent of domestic-developed is mainly cation double seasons at present
, there is the shortcomings of absorption loss is big, of high cost in ammonium salt type, lose the economic base of application.Special surfactant is due to valency
Lattice are extremely expensive, most of also to stop phase of basic research indoors, it is difficult to promote and apply at the scene.Amphion surface-active
Existing anionic hydrophilic base has cationic hydrophilic base and shows both sexes again in agent molecule, adapts to wider pH range, right
Metal ion has stronger chelation, available for high salinity, the oil reservoir displacement of reservoir oil of higher temperature, and can substantially reduce nonionic
Chromatographic fractionation effect when type surfactant is compounded with anionic surfactant.Therefore, zwitterionic surfactant
Research and development obtained people more and more pay attention to and concern, especially beet alkali ampholytic surface active agent has become three
One of hot spot of secondary oil recovery area research.
It is increasingly deep with oilfield exploitation degree, apply common oil reservoir it is neutral can preferable surfactant in high temperature
Ultralow interfacial tension cannot be formed with crude oil in middle LOW PERMEABILITY RESERVOIR, cause oil displacement efficiency to be deteriorated, seriously constrain oil recovery rate
Raising.In order to reduce oil/water interfacial tension to a greater extent, alkali (such as sodium hydroxide, sodium carbonate of high concentration are often added
Deng), for example, patent CN1439689A disclose a kind of alkali, mixed surfactant and polymer ternary composite oil-displacing system and
It is applied, wherein the alkali selected is Na2CO3.However, alkali brings huge injury to stratum and oil well etc. in use, seriously
Etching apparatus and pipeline, spend substantial contribution in maintenance, maintenance, considerably increase the financial cost of tertiary oil recovery.Patent
CN201310166961.5 proposes a kind of displacement composition for the vermiculate glues that anion surfactant is formed, Ke Yi
Recovery ratio is improved to a certain degree.Therefore, with single surfactant it is difficult to meet in view of the deficiencies of the prior art hypotonic in high temperature
Oil water interfacial tension is down to the displacement of reservoir oil requirements such as ultralow, heat endurance is good, compatibility is good under reservoir condition, offer one kind is provided and is existed
Steady chemical structure under the conditions of LOW PERMEABILITY RESERVOIR in alkali-free, high temperature, can form 10 with crude oil- 3~10- 4MN/m ultralow interfacial tensions,
