| 摘 要： | 通过对岩心、钻/测井及地震资料进行层序分析,将2套储油层合并到层序1的低位体系域中,建立了准噶尔盆地中部MXZ地区隐蔽油气藏成因模式。对层序1界面追踪发现,在坡折带附近低位域前积现象明显,沉积地层增厚,地层应斜层对比;而没有坡折之处,地形平缓,地层应平行对比;从而搞清了隐蔽圈闭成因机制,并总结出基准面变化是该区隐蔽圈闭形成的主控因素。在此基础上,结合低位域储油砂体展布特征分析,总结出该区新的隐蔽油气藏成因模式,即平面为朵叶状,横剖面为透镜状,纵剖面为平缓楔状。

| Abstract: | To establish the formation model of subtle reservoir in the MXZ area of the central Junggar Basin,after sequential analysis on core,well drilling/logging and seismic data,this paper integrated two sets of oil layers into the low-stand system tract of Sequence 1.Through follow-up investigation and research on this sequence boundary,it was detected that,in the vicinity of the slope break belt,tract sedimentary strata thickened with obvious foreset sand in the low-stand system tract,so oblique strata should be... |
