摘　　要：目前计算注水系统效率的主要方法是根据SY/T5625-1996标准,在测试注水机泵及注水管网运行效率的基础上,再计算整个注水系统的效率。对于低渗复杂断块油田,为了完成配注而进行二次增压注水后,其机泵设备数量很多,管网也十分复杂,系统中同时存在两个甚至多个压力系统,若采用上述方法,其计算过程十分繁杂,因此参考集输系统效率的能量平衡理论,采用黑箱方法,提出利用油田现场计量仪表录取的注水资料计算注水系统效率的方法。现场应用表明,该计算方法简单、快速,工作量小,是油田切实可行的注水系统效率计算方法。At present, the main method computing water injection system efficiency is in accordance with the Standard SY/T 5625, the efficiency of overall water injection system is calculated on the basis of detecting the operational efficiencies of injection pumps and injection pipeline networks. For the complicated block faulted oilfield with low permeability after secondary boosting water injection to fulfill distribution injection, there are a lot of equipment and pumps and complicated pipeline networks. Two or more pressure systems coexist in the system. If using above-mentioned method, the calculation procedure will be very miscellaneous and the workload will be very heavy. Therefore referring to energy balance theory regarding gathering system efficiency and applying 'black box' method, a calculation method of water injection efficiency is offered, which uses the recorded data by oilfield site measuring meters. The site application shows that the method is simple, fast and with small workload, and it is a really feasible method for oilfield water injection efficiency calculation.
