储层非均质性影响油层剖面的动用程度 ,从而影响油田开发效果。对储层层间非均质性研究 ,往往停留在仅仅依靠取心井分析资料而建立的概念模型上。本文在沉积微相研究的基础上 ,利用测井解释储层参数结果 ,将非均质性概念模型发展到预测模型 ,分区块、分开发层系、分砂层组计算了反映储层层间非均质性参数 ,分析了研究区各区块、各开发层系、各砂组储层非均质性及其影响因素。结合长岩心多油层水驱油室内试验、动态监测资料分析了储层层间非均质性对水驱油效率和油田生产的影响 ,提出了提高油层剖面动用程度 ,改善油田开发效果的措施
Reservoir heterogeneity affects the degree of utilization of the reservoir profile, thus affecting the oilfield development effect. Research on inter-reservoir heterogeneity often rests on conceptual models that are based solely on coring well data. Based on the study of sedimentary microfacies, we use log interpretation of reservoir parameters to develop the heterogeneity conceptual model into predictive models, sub-blocks and sub-layers, Inhomogeneity parameters are analyzed to analyze the reservoir heterogeneity and its influencing factors in all blocks, development strata and sand formations in the study area. Based on the laboratory test and dynamic monitoring data of the oil displacement in the oil reservoir of Changxinxin multi-reservoir, the paper analyzes the effect of inter-reservoir heterogeneity on water-flooding efficiency and oilfield production and puts forward some measures to improve the profile utilization and improve the oilfield development effect
