ADDITIVE FOR REDUCING GEL STRENGTH IN AQUEOUS LIME CONTAINING DRILLING FLUIDS

摘要

A method of drilling a well that involves passing an aqueous drilling fluid through the ground that has a liquid phase saturated with calcium hydroxide, which contains as an additive to reduce the resistance of the gel and the point of ductility, hydrolyzed cereal solids that comprise from about 15% to about 25% by weight of di-saccharides, tri-saccharides, tetra-saccharides, and penta-saccharides, and from about 75 to about 85% by weight of hexa-saccharides and higher.
