摘　　要：镇泾油田长8块超低渗油藏储层类型分为孔隙型、裂缝型2种,不同储层类型产生的地层压力传播效果不同。要保证油藏的开采效果,需明确不同类型储层对应的井网排布关系。为此,针对长8块储层地质特征,在油水井动态指标分析基础上,研究了不同储层类型的压力传播特征,并初步确定出相应的井网形式。然后应用矢量井网和数值模拟方法对不同井排距方案进行了模拟,预测出了井网的合理排距。该研究对长8块超低渗油藏不同储层类型的进一步勘探开发提供了初步理论依据。Block Chang 8 of Zhenting Oilfield belongs to extremely low permeability reservoirs,the types of which are pore type and fracture type.Pressure propagation effect in the reservoirs is different for each type reservoirs.Well pattern arrangement should be ascertained for each type of reservoirs in order to guarantee effective development of the oilfield.Therefore,based on geology characteristics and performance analyses of oil wells and water injection wells pressure propagation features of each type of reservoirs are studied and related well pattern are initially determined.Then different scenarios of well space and line space are simulated and reasonable line space of the well pattern is predicted by using sector well pattern and numerical simulation.The study result can provide a reliable basis for the further development of different types of extremely low permeability reservoirs of Block Chang 8.
