Abstract

Abstract:

Stability of emulsion is usually evaluated with broken emulsion-voltage method or centrifugal method. These methods, however, can not reflect the real stability of invert emulsion under high pressure and high temperature (HPT) conditions. A new method of evaluation is proposed in the present work, with which continuous test can be realized. The main equipment used is a Fann23C and a self-designed SW-I HPT electro-stability apparatus, and only 30ml invert emulsion mud is needed in a continuous experiment. Case applications indicate that the result of test is reliable and can be used to guide drilling performance.

Key words: emulsion, stability, high temperature, evaluation
