RESERVOIR CHARACTERISTICS IN THE SE UPLIFT, THE SOUTH OF SONGLIAO BASIN

Four types of reservoir have been generated deep in the SE uplift,the south of Songliao Basin.The previous studies have indicated that,sandstone and glutinite are the major reservoirs.The rocks in different faults are mainly detritus feldspar sandstone and feldspar detritus sandstone.Strong diagenesis changes reservoir ability to different extents.Due to the influence of various factors,three induced porosity zones,which have improved the storing ability of reservoir to different extents,have been developed in the reservoirs of sandstone and glutinite located in the southeast deep layer.It can be concluded through comprehensive evaluation that,the physical performance of reservoir bed in the first part of Quantou Formation in various faults is relatively better and it should be the major objective layer in future exploration.Physical performance of all layers in the Wangfu fault is relatively worse.
