Abstract
The black oil-displacing agent has the percentage composition of: sodium hydroxide and/or sodium silicate 15-25 wt%; nonly phenol 0-20 wt%; polyacrylamide 0.005-0.5 wt%; and coal gangue powder or efflorescent coal powder the rest. The production process includes the following steps: throwing coal gauge powder or efflorescent coal powder into reactor; adding sodium hydroxide and/or sodium silicate under stirring for reaction at 30-70 deg.C for 3-5 hr; and adding nonyl phenol and polyacrylamide under stirring for mixing to obtain the black oil-displacing agent. The present invention has the features of low cost, simple production process, simple usage and high efficiency. Its use in oil field can raise the oil yield and oil recovering rate greatly and lower water content in oil well.
Description
One, technical field:
Oil-displacing agent that the present invention relates to use on the oil field and production method thereof are a kind of black oil-displacing agents.
Two, background technology:
The oil-displacing agent cost that uses on the oil field is higher at present, thereby is difficult to apply.
Three, summary of the invention:
The invention provides low black oil-displacing agent of a kind of cost and production method thereof.
This black oil-displacing agent consists of by weight percentage: A, 15 to 25% sodium hydroxide, perhaps 15 to 25% water glass, perhaps 10 to 22% sodium hydroxide and 5 to 10% water glass; B, 0 to 20% appoint basic phenolic ether; C, 0.005 to 0.5% polyacrylamide; The coal drystone powder of D, surplus or weathering coal dust.
Above-mentioned coal drystone powder or weathering coal dust are 40 to 80 purpose powder.
This black oil-displacing agent production method is to carry out according to the following steps: the coal drystone powder or the weathering coal dust of aequum are put in the reactor, under agitation add sodium hydroxide or/and water glass, control reaction temperature is at 30 to 70 degree, reaction times is 3 to 5 hours, under agitation add times a basic phenolic ether and a polyacrylamide of aequum then, mix and obtain black oil-displacing agent.
The present invention has that cost is low, and production method is simple, and using method is also simple, the characteristics that efficient is high.After adopting this black oil-displacing agent on the oil field, can improve petroleum production and recovery ratio greatly, reduce well water.
