Effected by provenance from the depression northeast and the north, sandstones shaped as semicircle,are distributed in the depression northeast ,and then mudstone and silty argillite as its transition to the southwest. The sequence is classified into two types: alluvial fan-braided river sequence, which was formed by the strong tectonic movement in the lower Jurassic, lake-delta-meander river sequence that generated in the middle and upper Jurassic.
由于受凹陷东北部及北部双向物源的影响，砂岩呈半环状分布于凹陷的东北部，向西南部过渡为泥岩、粉砂质泥岩，研究中把层序结构分两种类型：既早侏罗世强烈构造运动形成的冲积扇-辫状河形的砂泥岩碎屑层序、中晚侏罗世形成的湖泊-三角洲-曲流河形的砂泥岩碎屑层序。

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。

Turner smoothes wood, it's with a $700 Festool hand sander that has a tiny built-in vacuum that sucks up the sawdust.'No cleanup!' he says. Some of Mr.
他打磨木料用的是700美元的Festool手动磨砂机，里面有个很小的内置真空吸尘器，"不用自己清理砂屑了，"他说。

在大宛齐油区识别出了三角洲平原和三角洲前缘两个亚相并从中进一步划分出了8种微相，查明了康村组岩性由不同粒级的岩屑砂岩的组成，分流河道砂体、水下分流河道砂体和河口砂坝砂体是油气的主要储集层，储层在纵向上多期叠置、在横向上频繁迁移、尖灭和连续性较差。

By studying reservoir rock characteristics, diagenesis and physical property, investigation showed that there were distributary channel, branch channel, mouth bar, distal bar, sand sheet, lakeshore, shallow lake and limestone flat . we concluded that the reservoir of N1～N21 is low porosity and permeability reservoir with the types of primary porosity and secondary intergranular porosity, which is in the early diagenetic stage B into the late diagenetic stage A subperiod. The role of effecting reservoir physical property is deposition, cementation, dissolution and tectonic rupture. After researching of reservoir, we divided it into three categories and division the favorable facies belt and relatively favorable. We think that the favorable facies belt is braided river delta front and partly shallow lake in east of the Fault Ⅶ. favorable reservoir is in the first and the second class.
进一步研究了本区碎屑岩储层的岩石学特征、成岩作用特征、物性特征，研究认为该区储集体类型有分流河道砂体、分支河道砂体、河口坝、远砂坝、席状砂砂体、滨湖砂滩、浅湖砂坝砂体及灰坪；N1层属于低孔、特低渗储层，孔隙类型以原生、次生粒间溶孔为主；分析了影响储层物性的因素主要为沉积作用、胶结作用、溶蚀作用和构造破裂作用；进行了储层评价与有利相带预测，将储层分为三类并划分了有利区带、较有利区带，认为Ⅶ号断层以东的辫状河三角洲前缘亚相和部分浅湖亚相是N1的有利储集相带，储层以Ⅰ、Ⅱ类为主。

It works by choosing appropriate gravel, scree, talus decries, coarse sand, medium sand, then ram them to be closely knitted. The sand gravel cushion can increase the bearing capacity of weak groundwork.
这种垫层法是用碎石、卵石、角砾、圆砾、砾砂、粗砂、中砂或石屑等坚硬、较粗粒径的回填材料，经合理级配并夯压密实后形成持力垫层，其主要目的是为了提高浅层软弱地基或不均匀地基的承载力。

It was considered that the control of the PRD fluid performance and the dosage of flow pattern adjusting agent PF-VIS were the key of the technique. The viscosity of PRD spudding fluid increased rapidly with the decrease of shearing rate, it indicated that it had good sand carrying ability. The spudding fluid was good capacity of high temperature stability under the low shearing rate, its viscosity was much higher than that of traditional drilling fluid, it was beneficial for cutting carrying in big deviated wells and preventing the formation of cutting bed.
认为要控制好PRD弱凝胶钻开液的性能，流型调节剂PF-VIS的加量是关键；PRD弱凝胶钻开液的粘度随着剪切速率的降低而急剧上升，显示了其优良的井壁携砂带砂性能；PRD弱凝胶钻开液体系具有较好的高温稳定性；PRD弱凝胶钻开液体系在低剪切速率的高粘度，大大高于传统聚合物钻井液，有利于在大斜度井携带岩屑以及防止岩屑床的形成。

61Ppm, REE distribution patterns of apatite standarded by NASA are classified into two types: The one is concave,"hat-shaped" REE pattern which is slightly enriched in intermediate REE and has a weak or even wanting Ce anomaly. To which, the sandy phosphorite of Jile is representative; the rest REE pattern is shown by more or less complete curve, although distinct Ce negative anomaly or weak Ce positive anomaly is shown up well. The stromatolitic apatite is the representative of this type.
其稀土元素北美页岩标准化配分型式主要分为两类：一类为中稀土略显富集的帽状形态的稀土元素配分型式，微弱的铈负异常或无铈异常，以极乐矿段砂屑磷块岩样品最为典型；另一类为轻稀土、中稀土和重稀土自然分异的三段弧形折线衔接而成的稀土元素配分型式，铈负异常较明显或微弱的铈正异常，以叠层石柱体磷灰石最典型。
