Experimental study on the flow rate measure and water cut measure response disciplinarian in oil-water two-phase flow of near horizontal small diameter pipe

在产出剖面测井中,井下油水两相流的流量和含水率是两个重要的测量参数。实验针对±5°内多个倾斜角度条件下,近水平Φ20mm小管柱内油水两相流动及其对测量仪器的影响进行了研究,总结了涡轮传感器测量流量及阻抗传感器测量含水率的响应变化规律,并从流动机理及测量条件出发分析测量影响因素,对水平井测量和解释具有很好的参考和指导意义。

The flow rate and the water cut of down hole oil-water two-phase flow are very important parameters in production profile logging.Experiments were carried out to study the oil-water two-phase flow regulation in near horizontal small diameter pipe with 20mm diameter under conditions of within ±5°multi-inclinations,and its influences on logging instruments were studied.The response disciplinarians of turbine flowrate sensor and the impedance water-cut sensor were summarized.The influences on the well logging were analyzed on the base of flow mechanism and logging condition.The experiment and analyses results play a good role in the guide of measurement and interpretation of horizontal wells.
