摘要:
针对目前广泛存在的日产量小于10 m3的油井及目前所应用的涡轮流量计测量下限较高和易砂卡等问题,根据流体力学相关原理,建立适合低流量测量的理论模型,分析其中的影响因素,采用独特设计技术,研制出外径为28 mm的浮子流量传感器。通过实验,确立油井流量在0~20 m3/d变化范围内,所研制的浮子流量传感器的测量频率响应与被测液体流量之间为线性关系。在模拟仿真系统所能提供的水流量下限(024 m3/d)和油流量下限(005 m3/d)情况下,传感器仍有较高频率输出响应,表明所研制的浮子流量传感器适合低产液油井流量测量。
Abstract:
At present, the production of oil wells is less than 10 m3/d, and the turbine flowmeter often provides nonaccurate log responses and results in sandingin problem, etc. According to the fluid mechanics principle, established are theory models for the low flow measurement, and analyzed are influence factors on the models. Developed is a unique float flow sensor with 28 mm diameter. Through a series of experiments, established are linear relationships between the measurement frequency response of the sensor and the measured liquid flow when flow variation range of the oil wells is 0~20 m3/d. Estimated is lower flow limit of float flow sensor, the result of which shows that even when the lower water flow limit is 024 m3/d and lower oil flow limit is 005 m3/d, the sensor also has higher frequency output response, which indicates that the float flow sensor developed is suitable for lower yield oil wells flow measurement.
