Abstract

Abstract:

Through the experimental study of existing evaluation method of mud cake compressibility, this paper compares the compressibility under normal temperature static / dynamic state, with three evaluation methods-"cake percotation rate","penetrometer", and "two stage water loss". The result shows that it is convenient to evaluate mud cake compressibility by means of "two stage water loss" method , especially under no mud-pouring, and the data is reliable. The compressibility of mud cake is resulted from both elastic and plastic deformations.

Key words: Filter cake, Compressibility, Permeability, Elastoplasticity
