摘要：

Lost circulation has been one the major challenges that cause much nonproductive rig time each year. With recent advances, curing lost circulation has migrated from plugging a hole to borehole strengthening that involves more rock mechanics and engineering. These advances have improved the industry's understanding of mechanisms that can eventually be translated into better solutions and higher success rates. This paper provides a review of the current status of the approaches and a further understanding on some controversial points. There are two general approaches to lost circulation solutions: proactive and corrective, based on whether lost circulation has occurred or not at the time of the application. This paper provides a review of both approaches and discusses the pros and cons related to different methods-from an understanding of rock mechanics and operational challenges.
