摘　　要：准噶尔盆地中部地区胜利区块已发现8套油气显示层位,6套获油流,含油岩性以粉-细砂岩为主,油气显示的深度界限差异大,最深可达6 000多米,油柱高度低,以非构造圈闭为主;根据油气藏赋存特征与成藏地质条件的分析,明确不同区块主要的含油层位及含油气差异与主要的油藏类型,中1区块J1s22和J1s12为岩性及构造岩性油藏,中2区块J2t、J1s和J1b为鼻凸构造背景下的岩性油藏,中3区块J2x及K1q为地层-岩性油藏,中4区块J2t及K1q以岩性油藏为主。中1和中3区块西北侧高部位、中2和中4区块东斜坡是重点勘探方向。In Shengli blocks of central Junggar basin, eight sets of oil-gas show horizons were found, of which oil flow was obtained in seven sets, dominated by lithology of sihstone and non-structural trap, characterized by big differences of depth of oil-gas shows （the maximum deep is more than 6 kin）, low oil column height. According to the occ, urrence feature and geologic conditions of oil-gas reservoirs, the main oil-bearing horizons, property differences and the main reservoir types in different blocks were determined. It is recognized that J1s2 and Js in Zhong-1 block are lothologic and litho-structural reservoirs; J：t, JLs and Jb in Zhong-2 block are lithologic reservoi with nose-like structural setting; J2x and Kq in Zhong-3 block are stratigraphic-lithologic reservoirs, and J2t and KKq in Zhong-4 block are dominated by lithologic reservoir. It is suggested that the structural highs in Zhong-1 and Zhong-3 blocks and the eastern slopes in Zhong-2 and Zhong-4 blocks could be as the targets for petroleum exploration.
