单井流量计量装置是为解决串联油井的单井量油而研究的，该装置由量油器、记录仪表及管阀附件等组成。其工作原理是将油、气、水混合物中的油、水液流量转化为电信号输出并加以记录，从而测量出单井的日产液量。重复性好，不受原油物性及含杂质的影响，适合抽油机脉动流态。在现场通过10口井的应用，它较好的解决了串联油井计量问题，能够保证油井稳定生产，提高油井生产时效，并为油井的科学管理提供了可靠的资料。 Single-well flowmeters are researched to solve single well oil in tandem oil well, which consists of dipole, recorder and pipe valve accessories. Its working principle is to convert oil and water flow in oil, gas and water mixture into electrical signal output and record it, so as to measure the daily production of single well. Repeatability, free from the impact of crude oil properties and impurities, suitable for pumping pulsating flow. Through the application of 10 wells in the field, it solved the problem of the measurement of tandem oil wells well, which can ensure the stable production of oil wells and improve the aging of oil wells, and provided reliable information for the scientific management of oil wells.
