东辛油田辛10断块为中高渗、稀油、常温常压、低饱和、半开启多油层断块油藏,针对该块含油层多、非均质强、开发时间长的特点,储层层间物性差异大、层间动用不均衡的问题,本次综合应用动态分析、监测资料等手段,分析各小层的水驱波及差异及储量动用差异,根据差异状况,通过细分注水立体开发,力争“四”个极致:逐小层完善井网,力争储量控制动用到极致;层系内细分注水,力争层间干扰减缓到极致;一体化工艺配套,力争平面水驱波及到极致;大井距强边水驱,力争产注能力发挥到极致,达到改善开发效果、提高采收率的目的。
The Xin 10 fault block of Dongxin Oilfield is characterized by medium-high permeability, thin oil, normal temperature and pressure, low saturation and semi-open multi-reservoir fault block reservoirs. In view of the characteristics of this oil-bearing block, strong heterogeneity and long development time, The difference between layers is large, and the use between layers is not balanced. The dynamic analysis and monitoring data are used comprehensively to analyze the difference of water driving and the differences of reserves in different layers. According to the differences, three-dimensional development , And strive to “four ” one extreme: by a small layer to improve the well network, and strive to maximize the use of reserves control; subdivision water within the system, and strive to ease the inter-layer interference to the extreme; integrated technology package, and strive to reach the plane water drive Extreme; big well away from the edge of strong water flooding, and strive to maximize the ability to produce a note, to achieve the purpose of improving the development results, improve oil recovery.
