COMPOUND FOR CONTROL OF DEVELOPMENT OF INHOMOGENEOUS OIL STRATUM Russian patent published in 2014 - IPC C09K8/88 E21B43/22 

FIELD: oil and gas industry.

SUBSTANCE: compound for control of development of inhomogeneous oil stratum includes stabilised latex, silicic acid derivative and water. As a silicic acid derivative is contains siliceous that represents a finely dispersed system based on silicone dioxide with silica modulus 100. It contains water activated electrochemically with pH 5.4 at electric conductivity of 3.7 mS. The compound includes the following component ratio, wt %: stabilised latex (on dry basis) 2-5, siliceous with silica modulus 100 in quantity of 2-5, the above water activated electrochemically - the remaining part.

EFFECT: increasing oil displacement efficiency.
