METHOD OF INCREASING OIL fracturing and porosity of the formation with artificially created cracks after fracturing - fracturing

摘要

FIELD: oil-and-gas industry.;SUBSTANCE: in compliance with proposed method, water solution is forced in artificially created fractures which contains 3-10 wt % of suspended mix of bentonite clay powder modified with quartz sand at their ratio of 10:1 - 1:2 and containing 0.01-0.30 wt % of partially hydrolysed polyacrylamide and 0.1-0.6 wt % of cross-linking agent, that is, chromium-containing compound.;EFFECT: higher recovery.;2 tbl
