泵效是衡量油田开发水平和管理水平的重要指标。盘古梁油藏为典型的低产低渗区块,单井产能低,系统效率低,盘古梁作业区经过十年的发展,采油工程工艺逐步趋于完善,但随着油井数的增多,产液量的增加,注水逐渐见效,抽油泵效却逐渐下降。为了提高盘古梁油田平均抽油泵效,结合作业区现状,从技术装备、油井参数及管理水平三个方面对机采井抽油泵效进行优化调整,通过提高抽油泵效措施的有效实施,在产液量和含水平稳的同时盘古梁采油作业区泵效由40.29%上升到12月底的44.67%。效果显著。
Pump efficiency is an important indicator of oilfield development and management level. Panguliang reservoir is a typical low-yield and low-permeability block with low single well productivity and low system efficiency. After decades of development in Panguoliang operation area, the oil recovery engineering process tends to be perfect gradually. However, as the number of wells increases, Increasing the amount of water injection gradually effective, pump efficiency is gradually declining. In order to improve the average pumping efficiency of Panguliang Oilfield and optimize the operation of pumping wells in the well from the aspects of technical equipment, oil well parameters and management level in combination with the status quo of the operation area, by improving the effective implementation of pumping pumping efficiency measures, At the same time, the pumping efficiency of Panguqiang Oil Recovery Project increased from 40.29% to 44.67% at the end of December. Significant effect.
