国内首次自营深水测试工艺技术

The First National Independent Deep-Water Testing Technology

随着国内海洋深水石油勘探技术的发展,海洋深水测试工艺技术已经成为深水油气勘探中的关键。南海x井是国内第一口自主设计、施工的深水测试作业井。对该井施工过程中的非旋转封隔器使用、水合物预防设计方案、深水管柱校核、水下树应用等进行了阐述,对深水测试的关键技术进行了分析和总结,对今后的深水测试作业具有一定的借鉴意义。

With the development of national deepwater oil exploration technology,well test technology to it has become a key work in oil and gas exploration of deep water. x well in South China Sea is the first domestic independent designed and operated well in deep water. The usage of non rotary packer,design of hydrate prevention,check of deepwater pipe string and application of underwater tree during operation to this well are described and the key technology of deep water test are analyzed and summarized,which has a certain reference significance for the deep water test operation in future.
