Improvement of the casing cementation of deep and ultradeep wells. Part 1: Drilling muds and washing fluids
Abstract
Drilling muds, washers, and washing fluids were investigated in order to improve the casing cementation of deep and ultradeep wells. Rheological requirements, the temperature stability of mud systems and the properties of nondamaging drilling muds were studied. For washing fluids, two test methods were developed and the necessity of filter cake removal was shown. The efficiency of several washing fluids was compared and evaluated for various mud systems (drilling muds with and without clays).
