摘要:
结合油藏开发阶段及特点，利用相控建立高含水期模型，研究平面非均质、层间非均质、注采比、采液速度、高含水关停井及水动力学注采方式对开发效果的影响；在经济评价的基础上，利用综合评价方法明确非均质油藏高含水期影响开发效果的主要因素，并提出科学合理的液流优化对策。研究表明，中渗非均质油藏高含水期周期注水能提高开发效果，不同相带周期注水方式不同。河道-河道注采时，水井通过短注长停方式能减缓含水上升；河道-侧翼注采，水井可通过长注短停方式提高采出程度；侧翼注采，水井采用对称周期注水方式能有效挖潜油层剩余油。典型某区块不同相带合理的采液强度不同，河道相合理采液强度为4.0 m3/（d?m），河道侧翼合理采液强度为3.0 m3/（d?m），可达到均衡采出，调整流线、控水稳油的目的。
Abstract:
Combined with the reservoir development stage and characteristics, a high water cut period model is established by using sedimentary facies control to study the effects of planar heterogeneity, inter-layer heterogeneity, injection-production ratio, producing liquid rate, high water cut shut-down wells and hydrodynamic injection-production method on the development effect. Based on economic evaluation, a comprehensive evaluation method is used to clarify the main factors affecting the development of heterogeneous reservoirs during the high water cut period and to propose scientific and reasonable countermeasures for the optimization of fluid flow. The study shows that cyclic water injection in the high water content period of medium-permeability heterogeneous reservoirs can improve the development effect, and the cyclic water injection methods are varied in different facies zones. In channel facies, the water cut rise can be slowed down by short injection and long stop of water wells; in channel facies and channel flanking facies, the degree of oil recovery can be improved by long injection and short stop of water wells; in channel flanking facies, the symmetrical periodic water injection can effectively tap the remaining oil in the reservoir. The reasonable fluid-producing intensity of channel flanking facies and channel flanking facies is 4.0 m3/（d?m）and 3.0 m3/（d?m）in a typical block, receptivity. This can achieve the purpose of balanced recovery, flow-line adjustment, water control, and oil stability.
