| 摘 要： | TLP使得干式井口在深水的应用成为可能,与常规的深水开发模式水下井口相比,TLP降低了钻完井作业的难度和费用,尤其在后期修井和调整并作业时,能够大大降低项目的投资,经济效益明显.TLP目前在墨西哥湾、北海及印度尼西亚深水油气田均有采用.目前针对TLP的钻完井设计和作业程序国内开展研究较少,制约了深水油气田开发前期方案设计工作的开展.因此,重点介绍了TLP对钻完井程序的影响;对于不同的平台钻机配置,总结了TLP的钻完井程序;提出了钻完井设计和作业过程中,TLP对回接套管、升沉补偿等问题的要求,分析了与常规深水湿式井口的温度剖面差异,为开展TLP钻完井技术研究和前期方案设计提供参考.

| Abstract: | TLP makes it feasible for application of dry wellhead to deepwater oil field development. Compared with conventional subsea wellhead, TLP can decrease the complexity and investment of deepwater oil field development, especially in the period of workover and operation in adjusting well. TLP has been used widely in GOM, North Sea and Indonesia. At present, there is not enough study on TLP completion design and operation procedure, which is restraint to the design of early oilfield development sce- narios. Therefore, in this paper, the focus is on the influence of TLP to drilling and completion procedures. For different model rigs, TLP drilling and completion procedures are summarized. The requirements for casing tieback and heave compensation during TLP drilling and completion procedure are put forward, and the difference in temperature profile between dry wellhead and conventional water wet wellhead is analyzed in this paper, which can provide referenced for study of TLP drilling and completion technologies as well as design of early oilfield development scenarios. |
