Study the membrane efficiency while drilling clay rocks
T.E. Guluzade - Azerbaijan State University of Oil and IndustryThe studies justified that while drilling oil and gas wells, in 75 percent of the cases the failure of wellbore stability occurred during clay rocks drilling. One of the reasons for this lies in the fact that during physical-chemical contact between the drilling mud and clay, the last one behaves as a semi-conductive membrane. To specify this property of the clay, the membrane efficiency concept is used. In this view, the study of membrane efficiency plays a significant role in the research of interaction between the drilling mud and clay rocks while breakdown of wellbore.
