摘要
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.关键词
