Abstract:  Well testing in exploratory wells offshore all adopt stratified testing, so it’ s necessary to study continuous testing in different layers without moving pipe string, to improve testing speed and efficiency, especially to reduce time and cost. This technology has been successfully used in a well at Bohai oilfield, the liquids and productivity at each layer is made known in one run, the testing cycle is largely shortened, the costs reduced. it will provide experience for similar well testing.

Key words:  , offshore exploratory well, one-trip testing string, new technology application

摘要：  目前海上油田多产层的探井测试都是以分层测试进行的，开展不动管柱分层连续测试技术研究、探 索测试增速提效和提高分层测试比例非常必要，而且在提高作业时效、节约作业成本方面有着尤为重要的意义。 通过对一趟管柱分层连续测试技术的研究及关键技术的把控分析，渤海油田某井成功应用了该项技术，准确明晰 了不同产层的液性及产能情况，大大缩短了测试作业周期，降低了作业成本。现场作业实践表明，该井成功的测试 经验可为相似探井测试提供作业经验，具有较高的推广价值。
