A new type of responsive controllable solidification plugging agent (RCSP) for long open hole intervals was developed, and the sealing characteristics were evaluated. RCSP had the characteristics of rapid water loss, high filter-cake consistency and good residence capacity. The experimental results indicated that the maximum pressure-bearing capacities of plugged zones in 5 mm and 10 mm slotted templets are 16.6 MPa and 11 MPa, respectively. So RCSP is an effective plugging agent for strengthening wellbore stability. RCSP is appropriate for sealing wide range of fracture sizes. Using RCSP-based plugging mud to address lost circulation problems in troublesome thief zones is a very powerful and economical approach. In the future, RCSP might hold great promise to resolve lost circulation problems in multiple leakage zones in long open hole sections.
