Abstract Seven intermediate term stratigraphic base level circles and the corresponding seven stratigraphic sequences could be distingushed in Upper Jurassic in Ludong Sag,Kailu Basin.The intermediate term stratigraphic circles could be divided into two long term circles correesponding to the basin's subsiding and fault depressing stages.The high resolution stratigraphic correlation framework of the sag could be established based on the principle of the stratigraphic circle correlation.It is suggested that the base level circles bear close relation to source reservior cap rock assemblage.The huge thick mudstone section deposited at the turning position from uprising to subsiding of the base level is the main hydrocarbon source rock and favourable reginal cap rock.The sandbodies formed during the uprising and subsiding periods are the main reservoir bodies.What's more,the assemblages formed during uprising period are usually of the type with source rock in the up part and reservoirs below,or self generation and self reservoiring type;that formed during subsiding period usually belong to the type of source rock below reservoirs.It is proposed that the first kind of assemblages are more favourable.

通过对钻井和地震等资料的综合分析,在开鲁盆地陆东凹陷上侏罗统中可识别出7个钻井中期基准面旋回以及与之对应的7个地震层序。7个中期旋回可合并成两个长期旋回LSC1和LSC2,并分别与盆地的稳定沉降阶段和强烈断陷阶段相对应。运用旋回对比原理,可建立起高分辨率地层对比格架。经研究,基准面旋回与生储盖组合的关系十分密切。基准面上升到下降的转换位置发育的大套泥岩段是区内的主要烃源层和良好的区域盖层。基准面旋回上升和下降阶段形成的各类砂体是区内主要的储集体。生储盖组合在纵向上的配置与基准面旋回的关系也十分密切,基准面上升阶段易形成上生下储和自生自储组合;基准面下降阶段易形成下生上储组合。基准面上升阶段形成的储盖组合更有利于油气聚集。

Through the comprehensive analysis of cores, logs and seismic data, six long term stratigraphic base level cycles and six corresponding seismic stratigraphic sequences can be distinguished in the Shahejie Formation , Lower Paleogene from the deep bed of West Depression, Liaohe Basin. In this paper, the relationship between the source reservoir cap assemblages and the long term base level cycle sequences of the Shahejie Formation are discussed in detail, and some knowledge is acquired as follow. That is, (1) in the stratigraphic framework of isochronostratigraphic correlation units of long term base level cycles, the sandbodies developed in the early middle stage of the uprising periods and middle late stage of subsiding periods are the main reservoir bodies, and the huge thick sections of black shale deposited at the turning position from uprising to subsiding of the long term base level are the main hydrocarbon source rocks and favourable regional cap rocks; (2) the characteristics of source reservoir cap rock assemblages developed in each sequence are distinctly different and controlled by the frequency, amplitude of the rising and falling of long term base level cycles, and the rate changes of lake level rising and falling, facies association, depositional sequence or fractionation , accommodation, A/S ratio of each stratigraphic sequence; (3) according to the disposal relationship of source rocks, reservoir rocks and cap rocks in the vertical or horizontal section of the formation, three types of basic assemblage can be divided. What's more, the first assemblage formed during uprising period with high accommodation is usually of the type with source rocks in the up part and reservoirs below, the second one fomed during subsiding period with mid high accommodation usually belongs to the type of source rocks below and reservoirs in the up part, and the third one fomed during the whole process of the base level uping falling cycle with low accommodation and only developed the reservoir cap combination without source rocks. By stacking the second and first basic types or second and third basic types, two complicated assemblage patterns across two stratigraphic sequences are made up and developed along the sequence boundary. It is proposed that the complicated patterns of assemblages are more favourable for reservoir of oil gas than the former three basic types.

通过钻井、岩芯和地震等资料的综合分析,可从辽河盆地西部凹陷深层沙河街组中识别出6 个钻井长期旋回层序和6 个相对应的地震层序。较为详细地讨论了沙河街组层序与生储盖组合的关系,认为:(1)在以中、长期旋回层序为等时地层对比单元的地层格架中,生储盖组合特征与长期基准面旋回关系最为密切,有利储层发育位置主要出现在基准面上升早中期和下降中晚期,转换处则是烃源岩或盖层的发育位置。(2)各长期旋回层序的生储盖组合具不同的特征,明显受基准面升降的频率、幅度及其所影响的湖平面升降变化速率、相组合、相序、可容纳空间和A/S值的变化控制。(3)按生储盖组合在垂向上和纵向上的配置关系,可划分为上生下储、下生上储和仅发育储盖的3种基本组合类型,第一种和第二种分别形成于中—高可容纳空间的基准面上升期和下降期,第三种形成于低可容纳空间的基准面完整升降旋回过程中。由第二种与第一种,或第二种与第三种基本组合类型的叠加组成2 种跨层序发育的复杂组合模式。相对前3种基本类型,复杂组合模式更有利于油气聚集成藏

Guided by the base level theory, the author

利用基准面原理对华北地区中、晚石炭世古地理进行了研究。划分出短期、中期和长期基准面旋回,并对基准面长期旋回进行了对比。在此基础上,分别将基准面上升期和下降期作为编图单元,进行古地理分析,对本地区沉积面貌有了新的认识:上升期(本溪组)发育两大体系,下降期(太原组)发育四大体系。认为:以基准面半旋回为编图单元,中、晚石炭世的沉积古地理的面貌更加清晰且规律性更强,在本区进行海陆过渡相基准面原理地层分析是可行的。图4参3(邹冬平摘)
