查询词典 rock-bottom

On the basis of generation and expulsion hydrocarbon history of source rock, seal formation history of cap rock, formation history of trap, active history of fault, oil or gas accumulation period by use of illite's ages, main oil or gas accumulation period was determined to be from the end of Yimin formation to the early of Qingyuangang formation.

根据源岩生排烃史、盖层封闭性形成史、圈闭形成史、断裂活动史和伊利石测年技术，综合研究得到乌尔逊凹陷油气成藏的主要时期为伊敏组沉积末期-青元岗组沉积早期。

Through the analysis of oil or gas accumulation conditions of K_1n_2 in Wuerxun depression, this paper points out that there are the differences in organic matter abundance of source rock, the quality space matching relation between caprock and source rock, the lateral seal of faults and oil or gas migration form of K_1n_2 between the south and north of Wuerxun depression.

分析了乌尔逊凹陷南二段油气成藏条件，结果表明：乌尔逊凹陷南二段南北部在源岩有机质丰度、盖源质量空间匹配关系、断层侧向封闭性和油气运移形式上存在着明显的差异性；乌尔逊凹陷北部南一段源岩有机质丰度、南二段和大一段盖源质量空间匹配关系、南二段断层侧向封闭性和油气运移形式均好于南部，导致乌尔逊凹陷北部南二段油气供给、运聚及保存条件均优于南部。这即是造成乌尔逊凹陷北部南二段油气显示好于南部的根本原因

The characteristics of sequence development, source reservoir - seal assemblage and types of hydrocarbon reservoir for each sequence were discussed in detail. The dark colored shale of deep lacustrine facies in the transgressive system tract of SⅡ sequence deposited around the maximum flooding surface is the main source rock in this area. The shale of shallow lacustrine facies in the TST of SⅢ sequence around the MFS is the most important regional seal rock.

结果表明，该区古近系可划分为SⅠ，SⅡ，SⅢ和SⅣ4个层序，分别对应于房身泡组、沙三段、沙一段沙二段和东营组。SⅡ层序水进体系域最大湖泛期沉积的半深湖深湖相暗色泥岩是研究区的主力烃源岩系；SⅢ层序水进体系域最大湖泛面附近的浅湖相泥岩是最重要的区域盖层。

Opening his eyes, he saw a large rock on his chest with a note on it that read,"Chinese Torture 1: Large rock on chest."

他睁开眼睛，看见一个大石头在他的胸口上，上面还有一个小纸条：&中国刑罚一：胸口上放一块大石头。&

Opening his eyes he saw a large rock on his chest with a note on it that read,"Chinese Torture 1: Large rock on chest."

他睁开眼睛，看到在他的胸上有块大石头，石头上粘着一张字条，上面写着，&中国式处罚之一：巨石压在胸上。&

There are many factors influence gas outburst, rock pressure was one of the important factors,and it was also a new contents to study rock pressure .

影响煤与瓦斯突出的因素较多，矿压对瓦斯突出的影响是其中一项重要的因素，也是现今矿山压力研究的一项新内容。

Because the underground reservoir rock is under high pressure and high temprature, it is very important to determine the relation between rock velocities and various pressures.

油气储层岩石在地下都处于高温和高压的环境，研究弹性波速度和各种压力的关系是岩石物性研究的重要内容。

In this paper, based on the common software Ansys, the method how to set up the contact element that between the pile and the rock for better simulating behavior of rock-socketed piles are studied. The visual software was written, which based on the improved elastic theoretic method and can be used to computing and plotting.

本文以Ansys软件为基础，在桩与岩土之间设置较合理的接触面对工程实例进行计算，又以改进的可以考虑岩石与土的分层性质的弹性理论法为基础，编制了一个具有计算及简单绘图功能的可视化软件。

At present, the researches at home and abroad concentrate on aquatic environmental influence of mine tailing and coal-gangue, but seldom focus on waste rock , which contrasts sharply with the present status of a large amount of waste rock pile in my country.

目前，国内外研究多集中于尾矿和煤矸石的水环境影响，对废石衍生水环境效应的过程、机制、影响因素研究甚少，这与我国大量废石的堆放现状形成了鲜明的对比，所以本文研究金属硫化矿业废石对水环境的影响有一定的实际意义。

Rock painting is a kind of picture carved or painted on the rock, which is a kind of cultural form for descriping the life and self-expression.

岩画是一种刻在岩石上或画在岩壁上的图画，是远古人类描绘生活、自我表述的一种文化形式。
