摘要
准噶尔盆地莫西庄油田侏罗系三工河组原油为优质稀油,埋深超过4 500 m,油层薄、低孔低渗、油水关系复杂,目前年产油仅5 000 t/a。运用深层微幅度构造薄油层勘探方法,利用测井曲线重构、地震资料全频扫描和分频处理、综合约束反演手段,达到了有效识别单油砂体的目的,得到了沉积构造背景控藏、沉积微相控砂、单油砂体控油、油层裙状富集、含油面积叠合连片的结论,对于该区勘探有一定的指导意义。
The Jurassic Sangonghe formation in Moxizhuang oilfield of Junggar Basin produces high quality light oil,but the reservoirs are buried below 4 500 m,thin,low porosity,low permeability,complicated in oil-water relationship,and producing only 5 000 t annually. Therefore,exploration methods for thin reservoirs in deep microrelief structure were used,including well logs reconstruction,full-frequency scanning and frequency division processing of seismic data,and comprehensive constrained inversion. As a result,single oil sand has been identified,and the conclusions are sedimentation and tectonic setting controlled hydrocarbon accumulation,sedimentary microfacies controlled sand bodies,single oil sand body controlled oil,oil layers concentrated in skirt shape,and oil-bearing areas are superimposed and contiguous.
