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.

It is important to repress hydrate generation in the gas well testing in deep water.But the related technologies haven't been applied in china until now.LW2 well is located on South China Sea with near 1500 meters depth of water.Before testing LW2 gas well,the technologies research is made about repressing hydrate generation and acquiring testing data.Subsequently,the research results are applied to the test.As a result,all the test data is acquired successfully as well as the testing experience in deep water.
