近年来,煤系气开采受到越来越多国家的关注。我国煤系气储量十分巨大,但其分布方式多以煤-砂互层为主,主要特点是煤层多(20-40层),单层厚度薄。若采用单层开采的方式,不仅成本高昂且收益低下。为经济高效的开采往往需要一口井贯穿十几个甚至几十个薄层区域,此时需要合采来提高效益。为了研究煤层气、致密气合采规律,基于煤层气的赋存和运移规律,综合考虑煤层气从煤层基质中解析、扩散,经由裂隙渗流到井筒的过程,结合煤层气在致密砂岩中满足达西渗流的特点,建立了耦合的煤-致互层储层两气合采数值模拟。通过采用有限元数值分析软件 COMSOL Multiphysics 进行数值求解 ... Read More
Structural, morphological and ground deformation studies suggest that the eastern flank of Mt. Etna (eastern Sicily) is spreading seaward. According to the deep-seated spreading model, both the volcanic edifice and its uppermost basement are spreading eastwards because of magma ... Read More
煤炭地下气化就是将处于地下的煤炭直接进行有控制的燃烧,通过对煤的热作用及化学作用产生可燃气体的过程。煤炭地下气化过程中,随着气化工作面的扩展,燃空区范围不断扩大,煤层顶板产生裂隙甚至发生冒落,对地下气化稳定运行造成不确定影响。相较于常规井工开采造成的顶板垮落,气化过程会产生大量热,顶板在煤层温度场高温作用下因热膨胀产生热应力,改变顶板内热应力的分布,同时温度会对顶板岩石的抗压强度、抗折强度、比热容、导热系数等造成影响。研究随着燃空区的逐渐扩展,顶板在温度影响下的应力场分布,对研究煤炭地下气化过程中的顶板冒落规律有重要意义。 ... Read More

煤层气开采过程中煤层所受应力、孔隙压力的变化以及气体的吸附解吸,会导致煤体骨架和孔隙体积发生变化,改变煤层的渗流能力。基于多孔弹性理论、渗流力学并考虑吸附变形,建立了煤层压裂水平井的物理模型,并建立了煤体变形和气体流动的全耦合数学模型,推导出了渗透率的动态变化模型。利用数值分析软件Comsol Multiphysics对煤层气的开发特征及规律进行了数值模拟,最终实现对模型中关键参数的敏感性和压裂裂缝参数的影响进行分析。 Read More

Many theoretical studies concerning lava tubes focus on the thermal disturbances generated on the earth surface. Recently a solution was suggested, where a lava tube located at a great depth h in the soil, where the ratio between h to the major axis of the ellipse a is higher than 10. ... Read More
