综合指数法在河流相储层非均质性研究中的应用
Applying of method of composite index in heterogeneity study of fluvial reservoir
摘要
Abstract
Reservoir heterogeneity is one of main factors that influence fluid distribution and migration of fluvial reservoirs. It also influences oil and gas exploitation result. Applying the division result of architecture, the theory of reservoir geology and the newest research method and the result of log interpretation, reservoir heterogeneity index is computed in terms of entropy's theory. Interlayer, intrastratal, plane and spatial heterogeneity are analyzed in term of different exploitation periods. Main influential factors of reservoir heterogeneity are analyzed. The relation between heterogeneity and remaining-oil is opened out. The results are as follows; Heterogeneity index is first computed in the work area which conquers the shortcoming of multi-parameter inconsistent characterization. Digital model is first established in term of exploitation period which shows the degree of reservoir heterogeneity becomes stronger. Architectures control the heterogeneous degree, diagenesis makes heterogeneity complicated and the deficient injection and production pattern increases the heterogeneity in evidence. Practice shows that heterogeneity index in terms of entropy's theory can acts as important function in characterizing fluvial reservoir heterogeneity and in predicting distribution of remaining oil.关键词
