岩性油气藏分布区定量预测新方法——以大民屯凹陷为例
A new quantitative prediction method for lithologic reservoirs distribution: A case from the Damintun Sag
摘要
Abstract
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 4 elements' combination in vertical and superimposition on the horizon control the strata and scope of lithologic reservoirs, respectively; they jointly determine the time of reservoir formation in geohistory. 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. T-CDPS model was applied to predict the favorable areas of lithologic reservoirs in Paleogene ES33, ES34 and ES4 strata of the Damintun Sag and has been proved feasible and effective.关键词
