摘　　要：辽河盆地东部凹陷南部地区火山岩十分发育，具有厚度大、分布广的特点。砂岩储层与火山岩是互层分布，其厚度呈负相关。通过对测井建立的沉积相模型进行沉积相带划分，预测出河道、天然堤微相及扇三角洲前缘亚相为有利的含油气相带；同时依据钻井资料分区块、分层追踪砂体，最后进行精细地震预测。采用这些综合研究方法部署的评价井和开发井均获得高产油气流。Volcanic rock is well developed in south of east depression in Liaohe basin,and has the characteristics of thick and vast. Sandstone reservoir and volcanic rock distribute alternately, their thicknesses are negative correlation. Through sedimentary factes division on model of sedimentary facies set up through well logging,it is predicted that profitable oilbearing zones are river course, microfacies of levee, and frontal sub-factes of fan-delta;at same time sandstones are recognized block by block and layer by layer according to drilling data;at last,precisc seismic prediction will be given. High production has been achieved from all the evaluation wells and development wells disposed by these methods.
