Subsea Completion Technology in the Liuhua 19-5 Gas Field

  • 摘要: 流花19-5气田属于边际气田,为降低开发成本,提高经济效益,需要新建水下生产系统。为此,进行了水下完井技术研究。针对水下完井技术难点,进行了海上水平井完井防砂及管柱设计,制定了防止井筒内形成水合物、结垢和结蜡的技术措施,优选了完井工具及完井管柱的材料,采用连续油管注氮气举排液技术投产,制定了锚泊定位半潜式平台漂移应急方案,形成了水下完井技术。流花19-5气田的2口井采用了水下完井技术,完井作业顺利,平均单井完井时间30.32 d。研究与实践表明,水下完井技术能够满足流花19-5气田高效开发的需求,可以提高生产效率,降低作业成本,实现边际气田的有效开发。
    Abstract: To minimize costs and enhance the economic efficiency in the development of the marginal Liuhua 19-5 Gas Field, a new subsea production system is required. Accordingly, the subsea completion technique was investigated. Sand control and string designs were completed for offshore horizontal well completion, and technical measures for prevention of hydrates, scaling and waxing in wellbores were proposed. Moreover, optimal tools and materials for completion tools and string were selected, gas-lift drainage by nitrogen injection with coil tubing was deployed for production, and the emergency response program for drifting of submersible drilling platform was developed. Thus, the new subsea completion technology was formed. It was successfully adopted in two wells in the Liuhua 19-5 Gas Field, with average completion time of 30.32 days. Research and application results showed that the new subsea completion system could enhance production efficiency, reduce operational costs, and realize the effective development of marginal gas fields.
