【摘要】 应用地理信息系统基本原理,结合煤层气地质学、天然气地质学、煤田地质学、构造地质学等学科的理论和方法,对煤盆地的典型代表阜新盆地的区域地质概况、盆地断裂网络的形成和分布进行深入研究。在此基础上借助ArcGIS平台,根据研究区混合气的生、储、盖条件建立了分析模型及空间分析数据库,应用于王营井田,对断裂网络进行分析,并对混合气的有利区块进行预测。认为煤层气、采煤尾气、砂体气、分散有机气和无机气是混合气的主要补给气源; 地壳运动和采矿活动产生的各种裂隙以及渗透性较好的倾斜煤、岩层为其创造了良好的运移通道; 砂岩层、节理裂隙带、断层带、裂隙发育的火成岩墙和采空区冒裂带是具有开发潜力的储气层(带); 煤系上部非渗透性岩层、含水层和第四系土层对混合气具有良好的封盖作用。在此基础上预测了王营矿区混合气的最佳富气带,为今后的混合气勘探提供了理论和技术方法参考,并为在煤炭枯竭型矿区勘探、开发和利用混合气资源提供了经验。更多还原

【Abstract】 The paper applies the fundamental of geographical information system, based on theories and methods of coal-bed methane (CBM) geology, natural gas geology, coal geology and structural geology, thoroughly studys the general regional geological situation,formation and distribution of cranny network in Fuxin basin. In virtue of the ArcGIS platform, based on generation-reservoir-overburden condition of admixture gas in this district, establishes analysis model and spatial analysis database, apply to Wangying well and analyses its cranny network, forecasts favourable region of admixture gas. It points out that coal bed methane、excavate coal tail gas,sandstone gas,dispersed organic gas and inorganic gas are main replenishment gas sources of admixture gas; various kinds of cranny ,which produced by the crust movement and mining activity and slope coal, rock layers of having good penetrability supply better migration channels ,sandstone layers,joint cranny zone,fault zone,igneous rock wall developing cranny and emit split zone of pick hollow area are gas storage layer and have exploitation potential ; non-penetrability terrane in top of coal series、hydrous layer and layer of soil in quaternary stratam have good close over action to admixture gas.Finally, the possible abundant-gas zone of admixture gas have been forecasted in Wangying mine field. At the same time, the paper provides theory and technology for the exploration of admixture gas and offer experiences of exploration, prospect and utilize of admixture gas in the future.更多还原
