Abstract
Relevance of the research. During hydraulic fracturing in clayed formations there is a problem of swelling of clays, which leads to a decrease in the permeability of rocks. It is necessary to reduce the effects of fresh water on the clay component of the reservoir. The negative impact of clays can be reduced by using special reagents - clay stabilizers.
Research objective: determining effectiveness of clay stabilizers "X" and "Y" on the consolidated core samples of wells 1,2,3,4,5 PJSC "Tatneft" in the composition of hydraulic fracturing fluid.
Object of studies: consolidated core samples from wells 1,2,3,4 of PJSC Tatneft.
Research methods: for the solution of the task were used filtration unit for high-temperature core tests PIK-OFP/EP-K-T. 2%, 3%, 4% solutions of clay stabilizers X and Y were tested by filtration through core samples. Pressure drop before and after filtration of clay stabilizer solutions and technical water through consolidated core samples was measured.
Research results: the effectiveness of clay X and Y stabilizers is evaluated.
