摘要

PROBLEM TO BE SOLVED: To provide a process for improving rheological properties of oil well drilling muddy water particularly useful for oil-based invert emulsion type drilling muddy water having more stable drilling fluid viscosity and anti-settling performance over varying temperatures when compared to conventional muddy water containing organoclay.;SOLUTION: The organophilic clay additive for oil-based drilling muddy water contains a reaction product of hectorite clay having a cation exchange capacity of at least 75 milliequivalents per 100 g of clay in an active clay standard with an alkoxylated quaternary ammonium salt and also contains the other organic cation, and the oil well drilling muddy water containing this organophilic clay additive and having less temperature-dependent rheological properties is obtained.;COPYRIGHT: (C)2002,JPO
