DISPERSION LIQUID FOR DRILLING AND MINERAL RESOURCES RECOVERY METHOD BY MEANS OF DISPERSION LIQUID

摘要

FIELD: oil and gas industry.;SUBSTANCE: dispersion drilling liquid is prepared by dispergation of the hydrolysable resinol material in the aqueous media, which contains the hydrolysable marginally resin, hydrolysable resin, accelerating the esters decomposition, and the hydrolysable resin, releasing the acid in the form of the polyoxalate. The downhole processing method includes the input operation of the above mentioned dispersion liquid into the downhole under the pressure to provide hydrolysis of the hydrolysable resin material in water at the temperature of at least 40°C.;EFFECT: processing fluid decomposition under specific temperature conditions with its simultaneous cost cutting and the possibility to use it in the large quantities.;12 cl, 1 dwg, 8 tbl
