海上探井压裂测试管柱研究与应用

Research and Application of Fracturing Test String in Offshore Exploration Wells

海上探井压裂测试作业日渐增多,压裂测试管柱关系到压裂作业安全、地层资料的求取,压裂测试管柱设计是海上探井测试作业的重要一环。综述了海上单层压裂测试包括管柱常规型压裂测试管柱及改良型压裂测试管柱的优缺点,分层压裂测试管柱包括滑套封隔器分层压裂管柱、电缆桥塞分层压裂管柱优缺点,及关键工具作用原理和关键作业流程。以上这些压裂测试管柱均成功应用于海上压裂作业和设计中,为海上压裂测试管柱的选择提供参考。

The fracturing test operation of offshore exploration well is increasing,and the fracturing test string is related to the safety of fracturing operation and the acquisition of formation data.The design of fracturing test string is an important part of the offshore exploration well test operation.This paper summarizes the advantages and disadvantages of offshore single-layer fracturing testing,including the conventional and improved fracturing test posts.It includes the advantages and disadvantages of the sliding sleeve packer,and the principles of key tools and key operation processes.These fracturing test posts were successfully applied in offshore fracturing operations and design for the selection of offshore fracturing test posts.
