本文结合XXX块二类油层七队动静态变化特点,通过综合分析,总结出本队存在的主要矛盾,阐明了这些矛盾对该区整体开发效果的影响。同时针对该区的自身特点,在精细地质认识的基础上,合理优化方案,通过实施交替注聚、深度调剖、注入井分层、采油井压裂等调整措施,较好解决了这些矛盾,注入井吸入状况得到改善,地层压力系统得到调整,含水回升速度得到控制,改善了该区的聚驱开发效果。
Combined with the dynamic and static changes of the seven teams in the second block of the XXX block, this paper summarizes the main contradictions of the team through comprehensive analysis and expounds the impact of these contradictions on the overall development effectiveness of the block. At the same time, according to its own characteristics of the area, based on the fine geological understanding, the program is optimized reasonably, and these contradictions are well solved by implementing adjustment measures such as alternate injection and injection, depth profile control, injection well stratification and oil well fracturing, Inhalation conditions in injection wells are improved, formation pressure system is adjusted, water recovery rate is controlled, and the effect of poly-flooding development in this area is improved.
