| 摘 要： | 安塞油田王窑区长6油藏属典型低孔低渗油藏,主力油层为长611油层。该储层物性差,微裂缝发育导致油藏非均质性强,注水及剩余油分布明显受裂缝影响。进入中高含水开发期后,综合含水率上升迅速,产量递减严重。在进行野外露头观测和室内岩心观察基础上,对裂缝类型、性质、规模、密度进行定性和定量描述,使用古地磁方法确定主应力方向。结合实际生产资料,对注水开发中裂缝发育引发的生产动态特征进行分析,对比王窑区裂缝分布综合图与油井见水方位综合图,用生产动态方法验证裂缝研究的正确性。采用油藏工程与数值模拟相结合的方法,分析裂缝对注水开发的影响和剩余油分布特征。根据王窑区长611储层裂缝发育状况和裂缝发育区剩余油分布特征,提出在控制注水压力的基础上,进行强化注水、合理布局有效井网,提高侧向水驱效率,以及注水剖面调整等措施。

| Abstract: | Chang 6 oil reservoir in Wangyao area,Ansai oilfield is a typical low porosity and low permeability one,and Chang 611 is the main oil reservoir.Chang 611 reservoir has poor physical property.The development of microfractures makes the reservoir strong heterogeneous,and influences the water injection and remaining oil distribution obviously.Since middle-high water-cut stage,the composite water cut has risen rapidly and oil production has declined seriously.Based on field outcrop observation and indoor core o... |
