Abstract: 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.
