Abstract
The invention discloses a treating agent for an oil layer penetrated by sodium polyacrylate. The treating agent is characterized by comprising the following materials in parts by weight: 135-150 parts of water-soluble sodium sulfonate, 35-50 parts of silicon oil, 7-15 parts of oleic acid, 1-3 parts of isopropyl alcohol, 4-8 parts of triethanolamine, 7-15 parts of sodium polyacrylate, 7-15 parts of dioctyl succinate and 7-15 parts of decabromodiphenyl ether. The treating agent disclosed by the invention has the advantages oflow cost, environmental-friendly effect, convenience in use and good effect, and the materials are easy to obtain.
Description
Technical field
The invention belongs to a kind of oil field chemical, particularly a kind of oilfield additive.
Background technology
Oilfield additive comprises degreaser, water cleaning agent, reverse-phase emulsifier, sewage clarifying agent, emulsion splitter, the agent of Ca, Mg and Fe ion remaval.In tertiary oil recovery process, along with polymer flooding and poly-table drive the extensive popularization of stimulation work technology in oil field, incident produced water disposal problem also becomes and is becoming increasingly acute with it, tradition oily(waste)water degreaser is generally inorganic polymeric aluminum class flocculation agent, this class flocculation agent is to general oily(waste)water, treatment effect is better, but to containing the sewage of polymkeric substance, can not reach the processing requirements of expection.Use inorganic poly-aluminium to have the unfavorable factor of 3 aspects: (1) has introduced high price mineral ion, has increased the corrosion of water system to equipment, when serious, can cause pipeline leakage, the seepage of the web members such as valve, directly impact is produced.(2) in the isolated oil of water station, contain a large amount of water, this part oil will come back to petrol station and dewater.Owing to having introduced high-valence cationic, increase the electroconductibility of system, very easily cause two high-pressure polar plates of electrical dehydrator to puncture, cannot set up high-voltage electric field, the normal operation that impact is produced.(3), for the sewage that contains polymkeric substance, polymeric aluminum class flocculation agent and polymer reaction, generate the large floc sedimentation of sticky shape, causes serious obstruction in the filtration unit of sewage disposal, pollutes filtrate, reduced production efficiency.Due to the singularity of bearing sewage for ternary combination flooding in oil, original water technology and water conditioner can not meet the requirement of water treatment far away.Oil field chemical, in a broad sense, mean the each lamp chemical for all technological processs such as petroleum prospecting, drilling, collection are defeated, mainly comprise mineral products (as removing soil etc.), general chemical (as various bronsted lowry acids and bases bronsted lowries etc.), natural product (as starch), inorganic product (as zinc carbonate) and special (fine chemistry industry) product (as polymkeric substance and tensio-active agent etc.).Refer in the probing of oil, Sweet natural gas, adopt defeated, water conditioning and improve recovery ratio process in an analog assistant used, it various in style, major part belongs to water-soluble polymers (as vegetable jelly, polyacrylamide, Mierocrystalline cellulose and biological polymer) and tensio-active agent (sulfonated petro-leum, alcohol radical or alkylphenol base oxethyl ether).Since nearly more than ten years, China's oilfield chemical technology development rapidly, has formed more wide oil field chemical market.China's new discovery oilfield reserve is limited, and the maturing field arduous task of taping the latent power, particularly for China's oil field feature, strengthens In Oil Field Exploration And Development, improves oil recovery rate, strengthen environmental protection, need more novel, efficient, oligosaprobic oil field chemical falls.The chemical displacement of reservoir oil is divided into: 1. polymkeric substance water drive.Soluble in water a small amount of thickening material (as partially hydrolyzed polyacrylamide or biological polymer), increase the viscosity of water, improve the fingering of water in the time injecting, improve oil recovery factor.Surfactant slug is the microemulsion being made into by sulfonated petro-leum or synthesising sulfonate and activity promotor alcohol, and it has ultra low interfacial tension, and (<10-8N/cm can by the mother oil displacement in kapillary out, improve oil recovery factor.Maximum difficulty is the loss (absorption, trapping, precipitation) will overcome tensio-active agent and flow in oil reservoir time.3. caustic waterflooding, injects oil reservoir by caustic soda water, reacts with the active ingredient in crude oil, forms emulsion, to improve oil recovery factor.
Through Chinese publication retrieval, do not find the scheme identical with present patent application.
Summary of the invention:
This bright object is; A kind of sodium polyacrylate infiltration oil reservoir treatment agent is proposed.
Sodium polyacrylate infiltration oil reservoir treatment agent of the present invention, it is characterized in that: it is filled a prescription by weight, by water-soluble sodium sulfonate 135-150 part, silicone oil 35-50 part, oleic acid 7-15 part, Virahol 1-3 part, trolamine 4-8 part, sodium polyacrylate 7-15 part, dioctyl succinate 7-15 part, decabromodiphynly oxide 7-15 part composition.
Sodium polyacrylate infiltration oil reservoir treatment agent of the present invention, it is characterized in that: it is filled a prescription by weight, by water-soluble sodium sulfonate 135-150 part, silicone oil 35-50 part, oleic acid 7-15 part, Virahol 1-3 part, trolamine 4-8 part, sodium polyacrylate 7-15 part, dioctyl succinate 7-15 part, decabromodiphynly oxide 7-15 part composition; By whole mixing of materials, at 35-60 DEG C, stirring reaction 2-5 hour, obtains product.
