摘要
Combining with the oil geological features of the western part of Daqing Placanticline, the controlling factors of secondary porosity are analyzed in this paper. The authors believe that secondary porosity in the study area is mainly controlled by mechanical compaction, diagenetic cementation, meteoric water filtering effects and dissolution of acid fluid such as organic acids. The three controlling factors such as compaction, organic acids and carbonate, confirmed their threshold value of controlling development of secondary porosity and the corresponding quantitative assessment model were set up. In order to check applicability of this method, the predicted results and the reserve areas are superimposed in this paper.
