应用电控配产技术控制无效循环
|
摘要
随着油田开发的深入,层间及平面矛盾日益突出,无效水循环问题严重,但常规堵水技术在堵掉高含水层的同时也堵掉了高产液层。为此,以油井为中心,应用电控配产技术进行分层配产,这一技术可以实现油井分层段产量的无级调节,寻求最佳生产状态,并根据油井端的需求,对应调整水井端,从而实现井组整体调整。现场应用30个井组,井组累计增油0.58×10~4t,平均单井日降液31.4 m~3,综合含水下降了2.43个百分点,累计控液27.38×10~4t,达到了减缓层间和平面矛盾,控制无效水循环的预期效果。
With the deepening of oilfield development, the contradiction between interlayer and plane is becoming more and more prominent, and the problem of ineffective water circulation is serious. But the conventional water plugging technique also plugging high liquid layer while blocking high aquifers. Therefore, take the oil well as the center, application of electronic control technology for producing layered production allocation, this technology can realize the stepless regulation of production well layering, seeking the best production status, and according to the oil well demand, the corresponding adjustment water wells, so as to realize the overall adjustment of well group.Field application of 30 well groups, well group total oil production increased by 0.58 x10~4 t, average single well daily drop 31.4 m~3, comprehensive water cut decreased by 2.43 percentage points, accumulative total liquid control 27.38 ×10~4 t, achieved the expected effect of slowing down interlayer and plane contradiction and controlling invalid water cycle.
