胡五块油藏目前已进入高含水开发后期,本文分析研究了高含水后期注采调整的典型做法:①精细构造研究,优选潜力小断块进行挖潜和完善;②精细动态分析,完善注采井网;③精细注采调整,利用监测资料加强层间认识;④精细一类高含水层挖潜,加大调剖力度,提高层系水驱效率。⑤精细动态调水,减缓老井自然递减。综合注采调整治理后,层系综合含水得到有效控制,递减减缓,其挖潜技术与经验,为类似油藏的后期开发提供了一套挖潜方法。
The five reservoirs of Hu have entered the later stage of high water cut development. This paper analyzes and studies the typical practice of injection and production adjustment in the later stage of high water cut: (1) Fine structure research, which has the potential of small fault blocks for potential tapping and perfection; (2) Fine dynamic analysis, Well network; ③ fine injection mining adjustment, the use of monitoring data to enhance understanding between layers; ④ fine a high aquifer potential, increase profile control efforts to improve the efficiency of water flooding. ⑤ fine dynamic water transfer, slow down the natural decline of old wells. After comprehensive management of injection and production, the comprehensive aquifer in the layer is effectively controlled and decreases gradually. Its tapping potential technology and experience provide a set of potential tapping methods for the later development of similar reservoirs.
