Research on A Novel Lost Circulation Control Tool—Intercepting Lost Circulation Control Tool

Abstract:

According to lost circulation control of large caves or fractures, the intercepting lost circulation control tool is used to intercept loss control fluid in certain position. This method can effectively plug the loss channels of large caves or fractures and solve the problems of severe mud losses. It will improve the quality and efficiency of drilling, reduce the drilling costs, and provide a new approach to special lost circulation control.
