作者近年来在冀中地区首次发现了钙质超微化石,首次在不同层位发现了海绿石,结合其它古生物、岩石矿物和地球化学标志,表明区内早第三纪时曾多次发生过海泛。本文对海泛特征作了详尽的描述,并依据层序地层学理论分析了海泛层位在时间和空间上的变化,指出受海泛影响最大的层位即密集段。近海内陆盆地受海水进侵或海洋气候的影响,故湖盆基准面与海平面的升降变化趋势近似,从而为在陆相断陷盆地中开展层序地层学研究奠定了基础。文中对海水进侵方向(通道)也作了探索性研究。

The authors attempt to use the concepts of sequence stratigraphy to nonmarine Mesozoic sediments deposited in Erlian basin. The shelf edge in nonmarine faulted basin is ambiguous at its gentle slope side, and storm base can be regarded as a reference base level for distinguishing the system tracts. 2 supersequences and 8 third-order sequences which consist of 8 to 20 parasequences have been identified in Cretaceous sediments of Erlian basin. The authors analyse the characteristics of sequence boundaries and condensed sections, summarize the characteristics of depositional systems and system tracts in space, and construct the relative change curve of the base level.

Making use of of the theories and methods of sequence stratigraphy, this paper detailedly analyses the distributing models of the sediments and lithofacies of seismic sequence B and C, the source rock, reservoir and carprocks of oil and gas are prospected, Both sequences B and C are Pliocene and late Miocene, they consist of lowstand systems tract, transgrassive systems tract and highstand systems tract, each of them subjects to certain rules in respect of sedimentary environments and lithofacies. The anal- ysed results show that lowstand systems tract of sequence C is mainly basin floor fan , but lowstand progradational wedge is well developed in sequence B. Owing to the depositional materials is not sup- plyed sufficiently, transgrassive systems tract of sequence C was fastly become thiner to the direction of sea, and it is mainly shore plain-bathymetric clastic sediments, carbonate rock and reefs develop on the high part of platforms; highstand systems tract carbonate sediments develop in the shelf regions. Rela- tively , the depositional materials are supplyed enough during sequence B sediments. Deltaic foreset in large S-type and obligue type configuration, developed in highstand systems tract, and composed of deltaic sand/mud sediments, prograde from shelf margin to the sea basin. The author suggest that both the bathymetric mud of transgrassive systems tract and the deltaic foreset mud of highstand systems tract may become hydrocarbon source rocks,if there were mature con- ditions of the organic matters, it would become good source rocks. Sand layers may be filled up in the basin bottom of lowstand systems tract, deltaic foreset sand body may be developed during highstand stage, and shelf carbonate rock, some of them may be good reservoirs. Transgrasssive systems tract mud may be a good regional caprock.

按层序地层学的理论方法,研究了万安盆地B、C二个地震层序的地层沉积和岩相分布模式,并对其油气生储盖层进行了预测。 B、C二个层序分别为上新世和晚中新世沉积层,它们均由低水位体系域、海进体系域和高水位体系域组成,各体系域在沉积环境和岩相分布上具有一定的规律性。分析结果表明:C层序低水位体系域以盆底扇为主,B层序则是低水位进积楔体发育。由于物源供给不足,C层序海进体系域和高水位体系域向海方向减薄较快,以滨海平原-半深海碎屑岩沉积为主,在台地高部位发育碳酸盐岩和生物礁体,在陆架区则有高水位体系域碳酸盐岩沉积。而B层序物源供给相对充分。高水位体系域发育大型S/斜交复合型前积结构,斜坡三角洲砂泥岩沉积特别发育,陆架边缘不断向海推进。海进体系域半深海泥岩以及高水位体系域前缘三角洲泥岩均可以成为良好的烃源岩,特别是二个层序中的“生油密集段”,如果条件成熟,则是极其重要的生油岩。低水位体系域的盆底充填砂、浊积砂、进积楔砂体,海进期发育的生物礁体、海侵砂体以及高水位期三角洲前缘砂体、陆架碳酸盐岩均可能具有良好的储集性。海进体系域泥岩是理想的区域盖层。
