摘要:

传统分段测试技术采用机械封隔器+工作筒模式，在大斜度井以及水平井等井况施工困难。连续油管水平井分段测试技术采用连续油管下挂电动封

隔器+多参数工作筒模式，所有指令均通过地面控制器电动控制。在连续油管推动作用下，一次下入同一支封隔器在不同层位实现电动坐封与解封，工作筒油嘴在不同层位实

现开与关，并获得多段油层温度、流量、含水率、压力等参数以及地层恢复压力数据。对金龙51井4个射孔段分段测试结果进行分析，确定了主产油层为第一层，达到精确评

估各段油层的目的。该技术实现了油层精准分采，具有一定的推广价值。

Abstract:

The traditional segmented testing technology adopts mechanical packer and working barrel

mode, which is difficult to operate in highly deviated wells and horizontal wells. Coiled tubing horizontal well segmented testing technology adopts

coiled tubing coupling electric packer plus multi parameter working cylinder mode, and all commands are electrically controlled by ground controller.

Under the promotion of coiled tubing, the same packer can be set and unsealed in different layers at one trip, and the oil nozzle of working barrel can

be opened and closed in different layers, and the temperature, flow rate, water cut, pressure and formation buildup pressure of multiple oil

layers can be obtained. The technology is tested in four perforating sections of Well Jinlong 51, and the main oil producing layer is determined as the

first layer by analyzing the test results, so as to achieve the purpose of accurately evaluating each section of oil layer. This technology realizes the

accurate separate production of oil layers and provides technical support for understanding the physical properties of multilayer and guiding

production.
