Abstract
A well-drilling anti-foaming agent is characterized in that: the agent is composed of in parts by weight: 10-30 parts of poly(sodium silanolate), 50-80 parts of water glass, 5-25 parts of aluminum stearate and 80-120 parts of diesel oil; and the preparation of the agent comprises: mixing poly(sodium silanolate) solution, water glass, aluminium stearate and diesel oil, stirring at 70-85 DEG C for 60-90 min to prepare the product. The well-drilling anti-foaming agent has the advantages of being easily available in raw material, low in cost, green and environment-friendly, convenient to use and good in effect.
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.).Oil field chemical, 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.
chinanew discovery oilfield reserve is limited, and the maturing field arduous task of taping the latent power, particularly for China's oil field feature, is strengthened 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.
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 drilling well defoamer is proposed.
Drilling well defoamer of the present invention, it is characterized in that: by weight, by multiple silicon shrinking alcohol sodium solution 10-30 part, water glass 50-80 part, aluminum stearate 5-25 part, diesel oil 80-120 part forms, by multiple silicon shrinking alcohol sodium solution, water glass, aluminum stearate, diesel oil at 70-85 ℃, stir 60-90 minute, obtain product.
