Description
Technical field
The invention belongs to a kind of oil field chemical.
Background technology
Oil field chemical, in a broad sense, mean in all technical processs such as oil exploration, drilling, collection be defeated is each
Lamp chemicals, mainly includes that mineral products (such as removing soil etc.), general chemistry product (such as various bronsted lowry acids and bases bronsted lowries etc.), natural prodcuts are (as formed sediment
Powder), inorganic product (such as zinc carbonate) and special (fine chemistry industry) product (such as polymer and surfactant etc.).Refer to oil,
The probing of natural gas, adopt defeated, water treatment and improve recovery ratio used in the process of an analog assistant, it various in style, big portion
Belong to water-soluble polymer (such as plant gum, polyacrylamide, cellulose and biopolymer) and surfactant (oil sulphur
Hydrochlorate, alcohol radical or alkyl phenol base oxethyl ether).The content of oilfield chemistry research is mainly the preparation of this chemicals, performance
Evaluation (including rationale), screening formula, detail design and on-the-spot test.Owing to reservoir condition is different, crude oil, water quality, rock
The different properties of stone, the specific aim of chemicals used (formula) is the strongest.In order to develop and reasonably use oil field chemical, need
Diverse discipline knowledge is (such as organic chemistry, inorganic chemistry, physical chemistry, Chemical Engineering, analytical chemistry, hydrodynamics, reservoir engineering
And computational mathematics etc.).It is emerging boundary science that oilfield chemistry has gradually formed, more and more comes into one's own.According to " 2013-
Chinese oil field chemical industry market research in 2017 and investment forecasting analysis report " [1] data analysis, since nearly more than ten years,
China's oilfield chemical technology quickly grows, and defines broader oil field chemical market.According to incompletely statistics, nineteen ninety-five is domestic
Oil field chemical consumption is 102.9 ten thousand tons, and by 2009, whole industry usage amount reached 1,470,000 tons.Between 15 years, oil field
The usage amount of product adds more than 42%, and market scale grows beyond 180%.Wherein, drilling well is maximum by chemicals usage, accounts for oil
The 45%-50% of the total consumption of field chemicals；Oil recovery chemicals is with high content of technology, accounts for more than the 30% of the always amount of disappearing.China's new discovery oil
Field reserves are limited, and old filed is taped the latent power arduous task, especially for China's oil field feature, strengthen In Oil Field Exploration And Development, improve oil
Field recovery ratio, strengthen environmental conservation, need the most novel, efficient, oligosaprobic oil field chemical drops.At present, middle petrochemical industry, in
Oil and major company of CNOOC three control China's most of oil and natural gas oil well, and during its oil mining
The preparation of drilling fluid and technical service are also general all by its special department liable.Drilling liquid technology service occupation of China concentration degree is relatively
Height, the top ten drilling liquid technology service enterprise market concentration is about 55%.The weight of drilling liquid technology service is engaged in nationwide
Point enterprise includes that Great Wall drilling fluid company of drilling project company limited, COSL, Shengli Oil Field bore
Well engineering company, middle oil Chuan Qing drilling project company limited, Sichuan RenZhi oil field Technology Service stock Co., Ltd etc..
At present, core intelligence oilfield services is the drilling liquid technology service enterprise of domestic private maximum.Refer mainly to the chemistry used by the chemical displacement of reservoir oil
Agent.The chemical displacement of reservoir oil is divided into: 1. polymer water drive.Molten for a small amount of thickening agent (such as partially hydrolyzed polyacrylamide (PHPA) or biopolymer)
Yu Shuizhong, increases the viscosity of water, improves the water fingering when injecting, improves oil recovery factor.2. surfactant slug drives, table
Face activating agent slug is the microemulsion being made into activity promotor alcohol by petroleum sulfonate or synthesising sulfonate, and it has ultralow interface and opens
(< 10-8N/cm, it is possible to by the mother oil displacement in capillary tube out improves oil recovery factor to power.Maximum difficulty is intended to overcome table
Loss when face activating agent flows in oil reservoir (adsorb, trap, precipitate).3. caustic waterflooding, injects oil reservoir by Caustic soda water, with crude oil
In active component reaction, formed 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；A kind of petroleum demulsifier is proposed.
The petroleum demulsifier of the present invention, it is characterised in that: by weight, by water-soluble sulfonic acids soda soap 45-60 part, Oleum Ricini
25-50 part, Oleum Glycines 4-8 part, Petroleum 20-30 part, Tween 80,8-15 part, whole materials are mixed by 2% ammonia 2-5 part composition
Closing, at 75-100 DEG C, stirring reaction 12-22 hour, obtains 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, user
Just, effective advantage.
