摘要:
針對目前廣泛存在的日產量小于10 m3的油井及目前所應用的渦輪流量計測量下限較高和易砂卡等問題,根據流體力學相關原理,建立適合低流量測量的理論模型,分析其中的影響因素,采用獨特設計技術,研制出外徑為28 mm的浮子流量傳感器。通過實驗,確立油井流量在0~20 m3/d變化范圍內,所研制的浮子流量傳感器的測量頻率響應與被測液體流量之間為線性關系。在模擬仿真系統所能提供的水流量下限(024 m3/d)和油流量下限(005 m3/d)情況下,傳感器仍有較高頻率輸出響應,表明所研制的浮子流量傳感器適合低產液油井流量測量。
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.
