A METHOD FOR ENHANCING THE STABILITY OF A WATER SENSITIVE, REACTIVE SUBTERRANEAN FORMATION

摘要

The present invention provides a kind of raising formation stability water sensitive, in the wellbore for reacting passed through stratum. The inventive process provides a kind of impacts of accurate evaluation cementing fluid in water sensitive, and reactive structure simultaneously can arrange into formula cementing fluid accurately in order to improve this structure of stability. When needed, it is formed on the other surface using infiltration semi-permeable membrane of the method for the present invention.
