【摘要】 本文在全面整理已有煤层气资料的基础上总结霍林河煤层气资源概况,综合运用煤层气地质学,天然气地质学、煤田地质学、测井学、岩石学、构造地质学等学科的理论和方法,结合钻测井、地质录井等方面的资料以及霍林河盆地煤田钻孔等勘探资料,在以前研究的基础上,深入分析研究区的煤层气地质条件,主要包括构造、区域水文地质、煤层厚度与深度分布、煤的含气性等。对勘探开发区域的地质背景、沉积相类型及聚煤作用、煤层特征及含气性、煤层气资源量计算、有利目标评价及部署等方面进行了详尽论述。总结了适合研究区特点的、可操作性强的研究方案。收集了霍试1井煤层气含量、工业分析、显微组分、试井、测井等资料,重新对本区的煤层气勘探开发前景进行评价。对霍试1井主力煤层做了等温吸附、有机显微组分、工业分析等项目的研究。根据近几年的煤层气地质研究,内蒙自治区二连盆地群具有良好的煤层气勘探前景。其中,位于最东端的霍林河盆地是二连及海拉尔地区煤层气勘探前景最好的地区之一。霍林河盆地含煤层系是下白垩统霍林河组,探明煤炭储量131×108吨,主要为褐煤,煤层埋藏深度一般在1000米以浅。初步工作显示,该区煤层较厚,含气量较高,煤层气地质条件比较优越。更多还原

【Abstract】 This article has been collated in a comprehensive information based on coalbed methane summary overview of coalbed methane resources in Huolinhe. Comprehensive use of coalbed methane geology、natural gas geology、coal field geology、oil well logging、petrology、structural geology and other disciplines theories and methods as its instrument, Combination of logging and drilling, geology logging and other geological information, as well as Huolin Basin coal field exploration drilling and other information, based on previous studies,earlier analysis of the geological conditions of coalbed methane in the study area. Mainly include the structural、regional hydrogeology、coalbed thickness and depth of distribution、coal gas and so on. Deals with their geologic background of explorating development in this regional precipitation facie form and gather coal role ,coalbed feature and Includes disposition coalbed methance resources calculation、beneficial target evaluaterating and disposition and so on proceed exhaustive expound.Summed up the characteristics suitable for the study area can be operable research program. Collection of Huo 1 well coalbed methane content、industry analysis、maceral、well testing、well logging data and Re-evaluation about exploration and development prospects for coalbed methane in this zone. Huo 1 well of the main coal seam to do the adsorption isotherm,organic macerals, industry analysis project.According to coalbed methane geological studies since recent years,Groups of Erlian Basin of Inner Mongolia Autonomous Region has good prospects for coal-bed methane exploration which is located in the easternmost ,Huolinhe and Erlian and Hailar Basin Coalbed Methane Exploration Prospect in the region are one of the best. Huolin Basin coal seam line are the Lower Cretaceous Huolinhe group, proven coal reserves of 131×10~8 tons, mainly lignite. Burial depth of coal seams generally less than 1000m. Preliminary work showed that the area thick coal seam、the higher gas content、coalbed methane geological conditions are relatively favorable.更多还原
