The anomalous behavior of filters of cement solutions in fine pores and cappilars

Abstract

Contamination of productive formations during well casing can be reduced by taking into account changes in the properties of filtrate in thin pores of formations, in which filtrates containing high-molecular compounds acquire abnormal viscosity and are structured, acquiring the properties of solid-like systems. The studies have shown the possibility of using the abnormal properties of the filtrate to regulate the fluid loss of cement slurries.
