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。
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 compared;in gentle terrains without the slope break,flat strata should be compared.Sequentially,formation mechanism of subtle trap is ascertained,and it is concluded that the change of base le-vel is the main factor that controls the formation of subtle trap in the MXZ area.Based on that conclusion and the analysis on sand distribution,new formation model of subtle reservoir is summarized,i.e.,the plane is lobate,transverse section is lentoid,and longitudinal section is sphenoid with gentle slope.
