摘要：

A report is presented on experimental investigations of properties of ordinary and heavier-type drilling fluids prepared from bentonite and hydromica clays, as well as from chalk, adding to them polyacrylamide and for comparison, other additives. It is shown that polyacrylamide is an effective stabilizer of chalk muds in conditions where sodium, magnesium and calcium chloride layers are present in the rocks drilled.
