摘　　要：辽河西部凹陷马南地区中深层的岩性油气藏尤其是沙三段浊积岩油气藏的勘探,一直未能取得较大的突破。根据目标区勘探需求及储层特征,探索总结了沙三段浊积岩储层预测流程;综合应用层序地层学技术、沉积微相划分技术及地震相分析、地震属性提取技术和叠后反演技术进行储层识别,并运用叠前反演技术对流体进行预测。预测结果与实钻结果吻合较好。部署马南13井获得成功,表明该技术具有一定的应用前景。Hydrocarbon exploration has always failed to make big breakthrough in lithologic reservoirs of Sha 3 member of Manan area in west sag of Liaohe depression. In accordance with exploration requirements and reservoir characteristics, the flow process of reservoir prediction of turbidite in Sha 3 member has been explored and summed up. Through comprehensive application of sequence stratigraphy technology, sedimentary micro-facies division technology, seismic facies analysis, seismic attributes extraction technology and post-stack inversion technology, reservoir identification technology has been carried out. Besides that, pre-stack inversion technology has been applied to predict fluids. The prediction results are in line with the actual drilling results and the successful deployment of Manan-13 well shows the technology is of good application prospects.
