In accordance with the main contradictions between high deterioration degree of coal and low permeability of coal bed , this paper predicts high permeability region by use of new technique and methods including stress field , curvature analysis and major stress difference analysis 针对沁水盆地煤变质程度高、煤层渗透率普遍较低的主要矛盾，利用新技术、新方法，利用应力场、曲率分析方法和主应力差分析方法预测高渗区。
The geochemical characteristics of coals from liyazhuang coal mine , sihe coal mine and fucheng coal mine of qinshui basin , shanxi province , were comparatively studied , and the thermal evolution degree , the contents of soluble organic matter and the biomarker characteristics of coals were discussed 摘要对比研究了山西沁水盆地李雅庄煤矿、寺河煤矿和附城七一煤矿煤岩的地球化学特徵，讨论了煤岩的热演化程度、可溶有机质含量、生物标志化合物特徵。
This paper is carrying out based on the chemical materials of huanhe group of cretaceous system of erdos basin , carrying on relativity analysis about tds and three major anion percentage of meq ( milligram equivalent ) , taking cluster analyses on tds and the three anion percentage of meq , the trend analysis of the percentage of the number of fresh water and the total water with the increases of anion percentage of meq , classifies the new index , divide the groundwater into three kinds according to percentage of meq of three major anion finally defining new groundwater water chemistry : definitely bicarbonate type , relativity bicarbonate type and non - bicarbonate types , point out that the possibilities of fresh water reduce in proper order of these kinds 鄂尔多斯地下水勘查是国家重大的地质调查项目，在地下水水化学研究的几次大型讨论会议上，专家们一致认识到，能不能利用鄂尔多斯盆地地下水勘查项目中的大量地下水水质分析资料，探索出一种新的水化学类型划分方法，对舒卡列夫分类中的25毫克当量百分数的分类界限加以重新考虑，而找出一个与淡水密切相关的x作为分类界限。本文就是以鄂尔多斯自流水盆地白垩系保安群环河组地下水水化学资料为基础而开展相关研究的。
Judging by the special topic " hydrochemistry study of automatic flow water basin about erdos cretaceous " from project of " erdos basin groundwater reconnaissance " investigated geology department of china , this paper selected establishing and applying of erdos cretaceous groundwater hydrochemistry spatial database ( ekghsdb ) as a question for discussion and carry out all works 本硕士论文依托中国地质调查局国土资源大调查“鄂尔多斯盆地地下水勘察”项目的“鄂尔多斯白垩系自流水盆地地下水水化学研究”专题，选择鄂尔多斯盆地白垩系地下水水化学空间数据库(以下简称ekghsdb )的构建及应用作为课题，开展研究工作。
From csql to csq5 , the barrier system was the main system . from psql to psq5 , the carbonate ramp was the main system and from psq6 to psq8 the main system was fluvial and fluvial - delta system in brackish basin . from psq9 - psql2 , the main system turned to the fluvial - delta system 晚石炭世csq1 ? csq5层序以碎屑海岸障壁?泻湖和碳酸盐缓坡沉积体系为主；早二叠世早期psq1 ? psq5层序以碳酸盐缓坡沉积体系为主，早二叠世晚期psq6 ? psq8层序以半咸水盆地河流、河流三角洲沉积体系为主；中二叠世psq9 ? psq12为陆相冲积扇、河流、湖泊三角洲沉积体系。
In the condensed sections analysis , the concept of water - bearing lacustrine basin condensed sections and non - water - bearing basin condensed sections are firstly put forward , and have been described their features of lithology , mineral and geophysics , and have been predicted their distribution . meantime , this paper has studied the geochemical characters of source rocks , and contrast betwee 同时，对有水湖泊密集段进行了烃源岩地球化学特征和烃源对比研究，确立了凹陷的含油气系统；对无水盆地密集段进行了盖层封闭能力的研究，确定了含油气系统的区域性盖层及顶部范围。
Aim at the present condition that the permeability of high rank coal reservoirs and its dynamic change regulation have been rarely studied , based on the modern testing technologies and actual measure data of coalbed methane ( cbm ) well with better drainage effect in qinshui basin , using the international advanced cbm well numerical simulation software ( comet2 ) , the dynamic change regulation of the permeability of high rank coal reservoirs during gas recovery has been discussed , using the gas and water recovery process in divided stage is matched 摘要针对高煤级煤储层渗透率尤其是其动态变化规律极少开展研究的现状，基于现代测试技术和沁水盆地排采效果较好的煤层气井实测排采数据，利用目前国际上较为先进的煤层气数值模拟软件comet2 ，采用分段拟合的方法对煤层气井的产气、产水过程进行历史拟合和修正，进而对高煤级煤储层渗透率在开采中的动态变化规律进行了探讨。
