中文摘要:
      下侏罗统三工河组为白家海地区油气勘探重要层系之一,层序地层格架存在争议,层内岩性油气藏的分布研究较少,阻碍侏罗系油气进一步勘探开发。在高分辨层序地层学理论指导下,通过对露头、岩心、地震及钻测井等资料分析,明确岩性油气藏在研究区时空分布特征。结果表明,三工河组划分为1个长期旋回,3个中期旋回及9个短期旋回;所建立的高分辨层序地层格架在区内等时对比应用较好。岩性油气藏发育受控于中期基准面旋回的演化,不同中期基准面旋回内储集砂体发育范围和叠置方式存在明显差异,造成岩性油气藏类型时空分布发生变化。其中,MSC1和MSC3有利于岩性油气藏的分布,推测靠近阜康凹陷附近,MSC2有利于形成大面积油气藏。
英文摘要:
      The Sangonghe formation of low Jurassic in Baijiahai area is one of the main hydrocarbon-bearing strata, where sequence stratigraphic framework has not reach agreement, and litho-stratigraphic reservoirs analysis has thin research base, all of which are the key reasons for hindering deeper exploration and development. The result shows according to the theory of the high-resolution sequence stratigraphic, combined with outcrops, cores, seismic, drilling and logging data analysis, Sangonghe formation has been divided into one long-term base level cycle,three mid-term base level cycles and nine short-term base level cycles, and sequence framework has a favorable application effect in study area. Litho-stratigraphic reservoirs are controlled by mid-term base level cycle, and reserve sands have different development region and superimposed type in different mid-term base level cycle, which causes litho-stratigraphic reservoirs has unequal distribution. MSC1 and MSC3 are helpful for development of litho-stratigraphic reservoirs, and MSC3 are helpful for development of oil reservoir near Fukang sag.
