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.

碳酸盐与陆源碎屑混合沉积方面对微相、相特征、旋回样式、沉积机理研究表明，龙门山地区泥盆纪稳定浅海相区Emsian期和Eifelian期混合沉积十分发育，颇具特色，明显可以划分为两种类型：混积Ⅰ型，泥质陆棚背景下发育风暴沉积组构，幕式风暴期产生具丘状层理、底流冲刷构造的钙质砂岩、介壳岩，平息期则形成具大量虫管和生物扰动的深灰色、黄绿色页岩及海百合茎灰岩，腕足动物等大量繁盛；混积Ⅱ型，砂泥灰质陆棚背景下以发育高能前滨沙滩及生物介屑滩为特色，近滨至陆棚的砂泥灰互为混合，三者比例接近，肉眼难以区别确切岩石类型。

According to the theory of hierarchical description of reservoir, geological entities of different orders is described step by step in Lamadian oil-field, and the technical standards which can be convenient to manipulate is established. Otherwise 7 kinds of fine depositional models such as large-sized depositional sandbody of braided river, meandering river, low-sinuosity-straight distributary channel, crevasse channel, channel bar, subwater distrbutary channel and sandsheets are established.

中文摘要本文根据储层层次描述原理，在宏观上对喇嘛甸油田不同级次的地质实体进行了逐级描述，确立了各个技术环节便于操作的技术标准，建立了大型砂质辫状河砂体沉积、大型曲流河沉积、低弯曲-顺直型分流河道沉积、决口河道沉积、心滩沉积、水下分流河道沉积、薄层席状砂体沉积7种类型精细的沉积模型。

The sediment sandstone layers of meandering stream are thin and varied laterally. And those of braided transport quickly and aggraded vertically. They increase hardness against improving the prospecting resolution.

由于曲流河相沉积砂体的单层薄、横向变化；辫状河相沉积的砂体迁移快、垂向加积等特点，增加了在勘探过程中对其分辨的难度。

Methods: On the basis of developing rats model of BRG by using method of bile-regurgitational liquid-filling, the rats were douched with different herbs, or normal saline respectively in different groups for 4 weeks, the effect of JJSNS to pathological histology was observed, and the gastrin in serum, molitin in plasma and the mucosal 6-keto-PGFu were measured by radioimmunoassay, and compared with Xiangshayangwei pill.

According to successfully extracting and graphing of uranium anomalies, the self-center uranium anomalies and their close relationship with meandering stream systems have been observed. The uranium anomaly always develops in the distributary and turning place of meandering stream system, and is related with thin sand area (whose sand thickness and sand ratio are less than 30 meters and 40% respectively), thicker coal, fine lithology, but the highest value of uranium anomaly exists in middle sandstone.

通过对铀异常信息的成功提取及平面编图，发现延安组中铀异常呈一个又一个具有自我中心的单元出现，且与曲流河沉积体系的关系密切：通常发育于河道分岔或转弯处；普遍发育于薄砂带，一般砂体厚度在30m以下，含砂率小于40%；铀异常单元与厚煤层关系密切；主要赋存于粒度较细的岩性中，部分也富集于煤中，但铀异常最高值富集于中砂岩中。

Based on the deliberate analysis of microfacies, the authors set up the gentle-gradient braided river sedimentary model and the multi-channel and low-sinuosity meandering river sedimentary model, and think that the most favorable reservoir is overriding sand bodies of channel bar and point bar and channel bed sand bodies is sub-favorable reservoir.

在深入细致的微相分析基础上，分别建立了缓坡型辫状河与多河道低弯度曲流河两种沉积模式，认为最有利的储集砂体主要为高能水道心滩和边滩叠置砂体，其次为河床滞留砂体。
