储集体的分布与储集体内部的非均质性主要受成岩作用不均一性所控制。根据这一认识,本文通过对有效储集空间形成作用定量分布的研究,划分出不同孔渗条件的成岩相,并通过建立成岩相与沉积相、地震相、测井相的相关判别模式,把点上成岩相的研究扩展到面上三维空间的定量研究,编制成岩相分布图,圈定有利成岩相区,预测储集区和储集体,并提出了用成岩相-孔隙体积法估算储集量的新思路。

Reservoir distribution and the heterogeneity within reservoir rocks are dominated by varying diagenesis,Up this knowledge allows studies on the quantltative distribution of the effective reservoir rocks with respect to their geologic process and clarification of the diagenetic facies with various porosities and permeabilities,Futhermore,the study is ex-tended from a point to an overall 3-D quantitative analysis by establishing discriminant correlation models between diagenesis and sedimentology,seismology and well-logging.Eventually the paper suggests a new approach to estimating reservoir capacity by diagenetic facies-pore volume.
