摘    要:
针对勘探程度较低的地区,提出了一套有效烃源岩的综合预测方法。其基本思路是,从钻井出发,井震结合,按由点到面、由剖面到平面的顺序分五步进行:确定有利沉积相带;确定烃源岩平面分布;划分区域沉积相分布;确定平面热演化分布;有效烃源岩分布预测。利用该方法,对北黄海某盆地侏罗系SQ1层序进行了有效烃源岩预测。

Abstract:
An integrated method of predicting the distribution of effective source rocks is proposed for the sedimentary basin with low- to middle-degree exploration. The basic idia is that combining well data with seismic data, the method includes five procedures from site to area and from profile to plane as follows: a) ascertaining the favorable sedimentary facies zone; b) ascertaining the distribution of source rock in plane; c) zoning the distribution of the sedimentary facies in region; d) ascertaining the distribution of thermal evolution in plane; and e) predicting the distribution of efficient source rocks. This method is successfully applied to predict the distribution of efficient source rocks in the Jurassic SQ1 sequence in a basin, North Yellow Sea, which is still during low- to middle-degree of exploration.
