| Abstract:With the brief discussion on the status of lost circulation control, the paper introduced the recent scientific research achievements in view of the high-strength fast dehydration plugging, the high-strength chemical thixotropic materials plugging and the swelling plugging materials, as well as the film-forming drilling fluid technology. The paper also presents that the key research directions in the relevance of loss zone characteristics judgment and plugging measures; broad spectrum plugging technology; integration of composite plugging materials and leak-proof technology; high-efficient materials for loss circulation control while drilling and leak-proof washing fluid system; and expansion tubular sealing technology. |
