摘　　要：胜利油田进入中后开采期,高含水、低产液油井数量逐年递增,平均单井产量降幅逐年增大。通过调研测试发现,目前油田在用的各类单井计量技术对低产液油井计量还存在液量计量准确度低;低产液井串接混输,无法实现单井量油。以上问题已严重影响了油田生产的稳定运行,而油田从未对低产液油井的计量进行过针对性的研究。针对这个问题,设计出一种移动式计量装置,在现场测试过程中又对其进行了改进。测试数据表明,该装置将原油产量计量误差减小至5%以内,并满足了实际检测符合率≥91.7%。With Shengli Oilfield stepping into the middle and late period of exploitation,the number of low-yield oil wells increases annually,together with the average output of single well reduced increasingly every year.Through the survey and test,it is found out that there are some problems existing in measuring low-yield wells by means of different kinds of measuring technology for single wells now available in oilfields,such as the low accuracy of oil liquid measurement,the concatenation and mixed transportation of low-yield wells,the difficulty of calculating the oil output of single well.The above problems have seriously affected the stable operation of oilfield production,but oilfield has never done some corresponding research aiming at the measurement of low-yield wells.According to these problems,a mobile measuring device has been designed and has been improved in the process of site test.The test data show that this device can reduce the errors of crude output measurement to less than 5%,and satisfy the coincidence rate of practical detection ≥91.7%.
