陈堡油田陈3断块E1f1油藏受构造控制的局部受岩性影响的多油层多油水系统的层状油藏,钻遇油层多,含油井段长,层间非均质性严重,针对开发过程中暴露的储量动用不均衡、层系划分较粗、采油速度偏低、地层压力下降较快等问题,经过三次开发调整,细分五套开发层系,采用逐层上返的方式进行开采,通过完善注采井网,提高采收率,目前生产运行态势良好,油田含水上升速度得到了有效的控制。
The E1f1 reservoir in Chen 3 fault block of Chenpu Oilfield is controlled by the structure and is partly controlled by lithology. The reservoir of the multi-reservoir multi-oil-water system has many oil-bearing formations, long oil-bearing intervals and serious inter-layer heterogeneity. During the development process, the reserves exposed are unbalanced, the strata are stratified, the oil production rate is low, and the strata pressure drops rapidly. After three times of development and adjustment, the five strata of development are subdivided, Mining, by improving the injection well pattern, improve oil recovery, production and operation of the current good situation, the rate of oil field water has been effectively controlled.
