文留油田文72断块区储层层间非均质性研究

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

The Study on Reservoir Interbedded Heterogenity of Block Wen72 in WenNan Oilfield

The heterogenetity of reservoir has influence on the exploitation degree of il formation section, so as to works on the development of oil field. The study of reservoir interbedded heterogeneity has always stayed on the concept model settled only on the core well analysis data. This paper, based on sedimentary micro-face research, makes use of the reservoir parameter result of logging interpretation, developing the heterogeneity concept model into predition model, calculates the parameters that reflecting the reservoir interbedded heterogeneity by blocks, development layers, and sand groups respesctively, analyses the reservoir heterogeneity of each block, development layer and sand group in the study area and the factors having effects on them. Combined with the indoor experimentation of long core and multilayer as well as dynemic testing data, analyses the effects of interbedded heterogeneity on the efficiency of water driving and oil field product, bring forward the measure to increase the information section explotation degree and improve the development result of oil field
