Abstract
The invention relates to a hexahydrotoluene antifoaming agent. The hexahydrotoluene antifoaming agent consists of 850 to 1200 parts of mineral oil, 80 to 100 parts of hexahydrotoluene, 40 to 60 parts of pentadiene, 35 to 70 parts of diglycol laurate, 15 to 20 parts of stearic acid, 99 to 150 parts of polyoxy propyl oxyethyl glyceryl ether and 5 to 10 parts of dimethicone. A product of the hexahydrotoluene antifoaming agent is obtained by mixing and stirring all raw materials for 12 to 15 hours at the temperature of 95 to 120 DEG C. The hexahydrotoluene antifoaming agent has the advantages of low cost, environmental friendliness, convenience in use and good effect, and raw materials are easily available.
Description
Technical field
The invention belongs to a kind of oil field chemical.
Background technology
Oil field chemical, in a broad sense, mean 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 use (fine chemistry industry) product (as polymkeric substance and tensio-active agent etc.).Finger 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).The content of oilfield chemistry research is mainly the preparation of this chemical, the evaluation of performance (comprising basic theory), screening formula, working design and test in place.Because reservoir condition is different, the performance of crude oil, water quality, rock is different, and the specific aim of chemical used (formula) is very strong.In order to develop and reasonably to use oil field chemical, need diverse discipline knowledge (as organic chemistry, inorganic chemistry, physical chemistry, chemical engineering, analytical chemistry, hydromeehanics, reservoir engineering and computational mathematics etc.).Oilfield chemistry forms emerging boundary science gradually, more and more comes into one's own.According to < < 2013-2017 China's oil field chemical industry market research and investment forecasting analysis report > > [1] data analysis, since nearly more than ten years, China's oilfield chemical technology development rapidly, has formed more wide oil field chemical market.According to incompletely statistics, nineteen ninety-five oil field at home chemicals usage be 102.9 ten thousand tons, and by 2009, whole industry usage quantity reached 1,470,000 tons.Between 15 years, the usage quantity of oil field chemical has increased more than 42%, and market scale increases over 180%.Wherein, drilling well is maximum by chemicals usage, accounts for the 45%-50% of the total consumption of oil field chemical; Recover the oil with high content of technology with chemical, account for always the more than 30% of the amount of disappearing.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.At present, China Petrochemical Industry, PetroChina Company Limited. and three major companies of CNOOC are controlling China overwhelming majority's oil and natural gas oil well, and the preparation of drilling fluid in its oil mining process and technical service are also generally all responsible for by its special department.China drilling liquid technology service industry concentration degree is higher, and the top ten drilling liquid technology service enterprise market concentration is about 55%.The key enterprise that drilling liquid technology service is engaged in nationwide comprises Great Wall drilling fluid company of drilling project company limited, COSL, Shengli Oil Field drilling engineering technology company, Chuan Qing drilling project company limited of PetroChina Company Limited., Sichuan RenZhi oil field Technology Service stock Co., Ltd etc.At present, benevolence intelligence oilfield services is the drilling liquid technology service enterprise of domestic private maximum.Mainly refer to chemical displacement of reservoir oil chemical agent used.The chemical displacement of reservoir oil is divided into: 1. polymkeric substance water drive.A small amount of thickening material (as partially hydrolyzed polyacrylamide or biological polymer) is soluble in water, and the viscosity of increase water, improves the fingering of water when injecting, and improves oil recovery factor.2. surfactant slug drives, surfactant slug is the microemulsion being made into by sulfonated petro-leum or synthesising sulfonate and activity promotor alcohol, 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:
The object of the invention is to; A kind of methylcyclohexane defoamer is proposed.
Methylcyclohexane defoamer of the present invention, it is characterized in that: by weight, by mineral oil 850-1200 part, methylcyclohexane 80-100 part, pentadiene 40-60 part, diethylene glycol monolaurate 35-70 part, stearic acid 15-20 part, polyoxyethyl propyl polyoxy ethyl glyceryl ether 99-150 part, dimethyl silicone oil 5-10 part forms, by whole mixing of materials, at 95-120 ℃, stirring reaction 12-15 hour, obtains product.
