摘要:

随着海洋石油进军深水步伐的推进,在南中国海深水作业实践中遇到一系列作业难点和挑战.恶劣的作业自然环境对深水完井提出了更高的技术标准和要求,在完井工具和设备,施工工艺与完井技术策略上与浅水及陆地完井差异明显.我国在深水钻完井方面处于起步阶段,相比国外存在不小差距.针对深水作业特点,分析了作业中的一些难点与关键技术以及深水完井的策略,研究了M深水气田完井关键技术,对射孔技术,精细化完井防砂控制技术,压裂充填技术进行了分析和研究.结合我国南中国海深水完井作业实践,对深水完井作业中的可能风险点和现场应对技术措施进行了总结和梳理.研究结果可为后续设计和作业提供参考.

Abstract:

With the development of offshore oil exploitation into the deepwater region, we encounter a series of difficulties and challenges in practice in the South China Sea during deepwater operation. The severe natural environment puts forward higher technology standards and requirements on deepwater well completion. In the aspects of well completion tools, equipment, construction technology and strategy, there exists obvious difference between deepwater tasks and shallow water or land operations. According to the characteristics of deepwater operation, some difficulties and key technologies are analyzed. The completion sand control, perforating technology, and fracturing filling technology are studied separately. In the deepwater well completion practice in South China Sea, the possible risk points and technical solutions are summarized. The results can provide reference for the subsequent design and operation.

Key words: deepwater well completion, strategy, sand control, perforation, fracturing
