Hybrids of carbonate and terrigenous sediments Carbonate with terrigenous sediments are of characteristic from Emsian to Eifelian in stable shallow-sea faciesregion in Longmenshan area, and they can be classified evidently into hybrid Ⅰ and hybrid Ⅱ(Jingbaoshi-type). Type Ⅰ produced in mud shelf setting occupied hundreds of tempestite beds in which bottom cast、 hummocky cross bedding sandstones、 coquina were inter-beddded with shales that beared a great deal of verm traces、 bioturbations、 benthic communities dominative of brachiopods. Type Ⅱ in sand-mud-marl shelf was characterized by high-energy foreshore sandbeach facies and shelly bank facies.

从实验结果可以看出，泥岩的吸附量大于灰岩，干酪根的吸咐量远大于泥岩和灰岩；而且吸附量随温度的升高而降低，随压力的升高而增加。

Mottles in leopard limestone have undergone rotational deformation and have certain preferred orientation,while the marly component shows distinct fea- tures of ductile deformation;it is r...

在露头尺度上，豹皮灰岩中的豹斑发生了明显的旋转变形并具有一定的定向性，而泥灰质成分则具有清晰的韧性变形特征，为较典型的碳酸盐糜棱岩；在微观尺度上，构成豹斑的白云石矿物未发生韧性变形，而泥灰质成分中的方解石具有明显的细粒化、拉长和定向。

Several points can be concluded for the area from this paper study:(1) Hydrocarbon mainly occurs in the lower interval of bioclastic limestone and dolomitic limestone(the special lithologic interval ) in Es_1 Member,in which solution pores well developed;(2) Traps are mainly anticlines controlled by f.

本文研究表明，大中旺地区油气主要分布在沙一段下部的生物碎屑灰岩和云质灰岩段，储层溶蚀孔隙发育；圈闭主要为受断层控制的断背斜构造；原油具有高密度、高粘度、中低凝固点、高初馏点、高含硫量和高胶质沥青质等特点，属于未成熟—低成熟油；油源为本地咸水环境下形成的沙一段暗色泥岩。

Using methods of sedimentary and geochemistry, this paper analyzed the sedimentary environment in the Majiagou Formation. It suggests that Member 1, Member 3 and Member 5 are characterized by a dry and hot climate as well as fall of the sea level. The area of Well Longtan 1 in the eastern basin is abundant of platform evaporites with the depositional anhydrite and salt rock, surrounded by a suite of dolomite intercalated by the thin layers of anhydrite from the anhydrite\|dolomite platform sediment. It deposits muddy dolomite, dolomitic limestone and fine\|grained dolomite in the limestone-dolomite platform and restricted sea.
