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。An integrated method of predicting the distribution of effective source rocks is proposed for the sedimentary basin with lowto 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 lowto middle-degree of exploration.
