The research on sedimentary facies and diagenesis of the reservoir combined with analyses of diagenesis effect of low permeability resevoir on the reservoir property and with division of diagenesis stages indicates that the genetic mechanism of the low permeability reservoir in this area is the filling and cementation of autogenetic mineral during diagenesis.

该项研究是建立在储层沈积相、成岩作用研究的基础上，通过分析低渗透储层成岩作用对储集物性的影响及成岩作用阶段划分，认为造成本区储层砂岩渗透率较低的主要原因是成岩期各种自生矿物的充填和胶结作用。

This study takes the reservoir of the Kela 2 gas field of the Tariam basin, the western China, as an example for understanding the relationship between the porosity and permeability and autogenetic minerals and textures of the clastic rocks on the vertical depth scale. The secondary pores are essential reservoir space in this gas field, moreover, their origin is closely related to dissolution of the frame grain of plagioclase and the cements of calcite.

本文以克拉2气田储层为研究对象，探讨了该区纵向深度上孔隙度、渗透率与矿物组合、结构上的变化，发现次生孔隙是本区储层的重要储集空间，并且与长石骨架颗粒和方解石胶结物的溶蚀密切相关。

Bitumen is similar to the cement and autogenic clay filled in reservoir pores, and it dramatically reduces reservoir porosity and permeability, increases reservoir heterogeneity and even changes the oil/gas accumulation history at a later stage.

沥青类似于充填在储集层孔隙中的胶结物及自生黏土，使储集层孔隙度和渗透率急剧降低，非均质性增强，甚至可改变后期油气的富集规律。

Compared with the high performance dam concrete for the Three Gorges Project, the low-heat and high performance dam concrete with High Belite Cement has excellent properties as follows

高贝利特水泥的研究，是中国建材院负责的国家&九五&重点科技攻关成果，顺应了水泥胶结材的发展方向。

The results indicate that reducing the cementitious material content and sand-aggregate ratio can decrease the creep of SCC .

试验结果表明，在满足自密实混凝土工作性及力学性能的前提下，减小胶结料总量和砂率可以降低自密实混凝土的徐变。

In the North Ordos basin the sandstone-type uranium deposits developing in the system of sandstone beds of sedimentary facies of braided river course in Midde Jurassic Series,at the same time it happen some show of ore:the alteration zone of chloritization,bleaching decoloration and carbouation of epigenetic alteration,which show of ore are immediate and indirect for uranium mineralizing process.

摘 要：发育于内蒙古鄂尔多斯盆地北部中侏罗统直罗组辫状河相杂砂岩体内的砂岩型铀矿，有一系列较为特殊的与放射性铀成矿有直接或间接关系的成矿地质现象：绿色化蚀变带、漂白退色化带、二次胶结钙化砂岩团块及钙化砂岩断续层与&钙化木&后生蚀变现象；在与铀矿化和与油气的关系认识上存在一定分歧。

Four main formations of loop bedding in Jiyang sub-basin were upper layers fall down in the process of earthquake, tautening distortion due to earthquake, the frication of earthquake-related surface of fault and the effect of redox and diffuse other formations of loop bedding comprise the effect of earthquake wave, the effect coming from circumrotate of globosity rotation, snowball function, cementation intermittent, the effect of biology, and so on.

综合分析认为震动塌落、震动拉伸变形、地震断裂面的摩擦作用、氧化还原反应和扩散作用是环状层理的主要成因，前三种成因的环状层理往往与其他震成构造伴生，可作为震积岩的良好标志。环状层理的其他成因还包括：地震波传播方式的影响、地球自转产生的涡旋的影响、&滚雪球&效应、间歇胶结作用以及生物成因等。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
