摘要
The regional caprock(C), favorable sedimentary facies(D), surface potential(P) and source rock(S) are 4 functional elements that control the formation and distribution of lithologic reservoirs in the Damintun Sag. Based on this,this paper proposes a T-CDPS model with 4 functional elements to control hydrocarbon distribution and the method of predicting the favorable areas of lithologic reservoirs. The integrated probability index of the factors’ control on reservoir, calculated by the weighted mean of the probability index of single factor’s control on reservoir that is obtained by the analysis of its hydrocarbon controlling process and quantitative characteristics, can help predict the favorable area of lithologic reservoir distribution.
