定容管活塞式油气水多相流量计

Piston-type oil-gas-water multiphase flowmeter with constant volume tube

为验证定容管活塞式油气水多相流量计的计量精度及适用性,在XJ24-3平台和EP24-2平台上进行测试实验。受现场测试条件限制,将多相流量计串联入测试管汇。8口单井实验结果表明,多相流量计计量液量和含水率测试与传统测试分离器计量和手工取样测含水的结果误差约±5%;与平台上现有传统计量设备相比,能快速进行单井井口计量切换,且测试结果吻合度较好。该多相流量计现场环境友好,计量准确快速,可简化现场工艺流程,具有推广应用价值。

In order to verify the measurement accuracy and applicability of the piston-type oil-gas-water multiphase flowmeter with constant volume tube,test trials were carried out on XJ24-3 platform and EP24-2 platform.Due to the limitation of field test conditions,multiphase flowmeters were connected in series to the test manifold.The test results of 8 single wells show that the error of liquid volume and water content measured by the multi-phase flowmeter was less than±5%when compared with the results of traditional separator measurement and manual sampling measurement.Compared with the existing traditional measurement equipment on the platform,the multi-phase flowmeter can quickly switch the metering of wellhead in single well,and the test results were in good agreement.The multi-phase flowmeter was environmentally friendly,accurate and fast in measurement,and can simplify the process flow on site.It has the values of popularization and application.
