高地层压力变化原因分析及对策

Analysis and Countermeasure of high pressure change of highland

东庄油田属于水驱断块油藏,进入中高含水期开发阶段的油田,综合含水超过60%,稳产难度越来越大,稳油控水成为油田开发工作者的主要任务,地层压力过高导致油水井套损,水井作业泄压时间长,油井低能、低效生产,根据油藏特点建立合理的注采系统。

in Dongzhuang oilfield belongs to water flooding reservoir in fault block,into the oil field in high water cut stage ofdevelopment,composite water cut is more than 60%,stable yield more and more difficult,stabilizing oil production and controlling waterbecomes the main task of the oilfield workers,the formation pressure is too high resulting in casing damage of oil and water wells,wellsoperating pressure for a long time,the oil low,inefficient production,according to the characteristics of the reservoir to establish reasonableinjection production system.
