Study On Sedimentary Facies Of Xinglongtai Oil Layer In Central-south Of The West Slope In Liaohe Depression

The research area located in the south-central west pitch of the West Hollow of Liaohe Basin, which is the important oil-bearing region, take up approximately 260km2. This research had based on the exploration research results in the full absorption, take the well drilling, the oil well logging and the sesmic material as the foundation, through the division and comparation of subzone to divid the Xinglongtai Oil layer into 3 oil measure 20 subzones; Studies the space-time distribution and the match relations of sand body based on the subzone unit. On this foundation, take the sesmic, the oil well logging analyzes as the method proposed the research area located in the fan-delta front, and elaborated the developmental rule of each micro-facies. Through the oil well logging restraint reservoir sesmic inversion, the space-time distribution characteristic of all various sandbody has been explicit. XingIII oil measure of Xinglongtai oil lay was the superiority through the synthetic study, and carried on simulates of the sedimentary micro-facies, to expound furtherly vertically and horizontally distribution rule of the sedimentary micro-facies. In the above foundation, forecast the advantageous area of sandstone reservoir distribute, present the exploration deployment proposal.
