松辽盆地南部东南隆起区深层发育4种类型的储层,以往的勘探成果证实,砂岩、砂砾岩是主要储集层.各断陷的岩石类型主要为岩屑长石砂岩和长石岩屑砂岩.成岩作用强烈,不同程度地改变了储层的储集性能.由于各种因素的影响,盆地东南深层的砂岩和砂砾岩储层中,发育3个次生孔隙发育带,不同程度地改善了储层的储集条件.综合评价认为,各断陷中泉头组一段储层的物性相对较好,应是今后勘探的主要目的层;王府断陷各层位的储层物性相对较差.

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.
