| 摘 要： | 随着油气勘探向深部发展.深层油气藏已成为油气发现的重要组成部分.永进地区位于准噶尔腹部中石化中部3区块,勘探目的层埋藏深.大于5 500 m,储层主要以细砂岩、含砾砂岩为主,颗粒具有岩屑含量高、成分成熟度低、结构成熟度低等特点;多为特低孔、超低渗储层:储层孔隙类型有5种:残余原生粒间孔、粒间溶孔、粒内溶孔、泥质微孔和微裂缝;孔隙结构为特小孔微细喉型.储层物性影响因素主要有强烈压实成岩作用、弱溶解作用和黏土矿物充填3个方面.均造成孔渗性下降.该区油藏类型主要为地层、岩性油气藏,成藏模式为源上沿断-沿层油气成藏模式.

| Abstract: | With the development of the petroleum exploration, deep oil and gas reservoirs become more and more important. The Yongjin area is one of the three blocks in the interior of the Junggar basin explored by the Sinopec. The exploration target in the Yongjin area is deeper than 5 500 meters, with reservoirs mainly consisting of fine sandstone and pebbled sandstone, skeleton grains being characterized by higher ratio detritus, lower compositional maturity, lower texture maturity, with very low porosity and super... |
