| 摘要 |
FIELD: oil and gas production. SUBSTANCE: invention aims at increasing resistivity of drilling mud and oil-bearing minerals and raising permeability of well bottom zone. The aim is achieved when treating drilling mud with water-repellent additive based on organosilicon compounds and tall oils in 1: 1 proportion. EFFECT: improved quality and reliability of defining oil- saturation extents and preserved as much as possible natural permeability of well bottom zone. 2 tbld
