通过该立排井的施工，总结了施工过程中出现井内漏失引起的井口坍塌事故时，应该采取的必要的技术处理措施。事故发生后，必须以安全为先，妥善处理孔内事故；处理完孔内事故后，应该及时加固设备下地基，尽量减小设备下地基应力，下套管时应采用浮力阀平衡一部分套管重量，并把井口处所立钻具拖出场房外，为安全施工创造条件。
通過該立排井的施工，總結瞭施工過程中齣現井內漏失引起的井口坍塌事故時，應該採取的必要的技術處理措施。事故髮生後，必鬚以安全為先，妥善處理孔內事故；處理完孔內事故後，應該及時加固設備下地基，儘量減小設備下地基應力，下套管時應採用浮力閥平衡一部分套管重量，併把井口處所立鑽具拖齣場房外，為安全施工創造條件。

Through the construction of the vertical shaft, summarizes the necessary technical treatment measures meeting the collapse of the wellhead caused by the borehole leakage in the construction process, after the accident, insuring the safety in ifrst, properly handle the trouble inside the bore hole;after treating the accident, should be timely reinforcement equipment foundation, try to reduce the stress of equipment foundation, the casing should be used when the buoyancy balance valve part weight, and the wellhead vertical drilling drag off premises outside the room, to create the conditions for the safety of construction.
