摘要: 储层流体能量是进行煤层气开发的主要动力,是煤层气获得高产的关键因素,查明煤系地层流体能量特征对煤层气有利区段优选具有重要意义。以恩洪西南区块为研究对象,基于抽水试验数据和煤田勘探资料,从视储层压力、水动力场和水化学场3个方面分析了研究区垂向流体能量层域特征,发现不同层段差异明显,含煤地层普遍属于欠压状态,中段压力系数平均为0.86,流体能量相对最高;上段水动力条件明显强于中、下段,与周围含水层水力联系较强,有利于实现排水降压;上段地下水封闭指数平均为11.96,水质类型主要为HCO-3—Ca2+型,封闭性较弱,水化学环境较开放;各层段含气量均较高且差异较小,不构成约束开发的限制条件。提取压力系数、单位涌水量、渗透系数、影响半径和地下水封闭指数5个水文地质评价指标,运用灰色关联分析法对不同含煤层段的开发潜力进行了初步评价,认为上段为较有利开发层段,推荐为优选层段,各含煤层段递进开发顺序为上段→中段→下段。

Abstract: Reservoir fluid energy is the main driving force for coalbed methane development,and it is the key factor to obtain high production.It is of great significance to identify the fluid energy characteristics of coal measures to optimize the favorable sections of coalbed methane.In this paper,take the southwestern of Enhong block as the research object,based on pumping test data and coalfield exploration data,the layer characteristics of vertical fluid energy in the study area were analyzed from three aspects of apparent reservoir pressure,hydrodynamic field and water chemical field.It is found that there are obvious differences in different layers.The coal-bearing strata generally belong to under-pressure state.The average pressure coefficient of middle section is 0.86,and the fluid energy is the highest.The hydrodynamic condition of upper section is obviously stronger than the middle and lower sections,and has strong hydraulic connection with the surrounding aquifers,which was conducive to the drainage and depressurization.The groundwater closeness index of the upper section is 11.96 on average,the type of water quality is mainly HCO-3-Ca2+ type,indicating weak closeness and relatively open water chemical environment.The gas content of each section is high and the difference was small,which does not constitute the restriction condition of constraint development.The 5 hydrogeological evaluation indexes,including apparent reservoir pressure coefficient,unit water inflow,permeability coefficient,influence radius and groundwater closeness index,are extracted,and the development potential of different coal bearing sections is preliminarily evaluated by using grey relational analysis method.It is considered that the upper section is the favorable development layer,and is recommended as the preferred layer.The progressive development order of each coal bearing section is:Upper section → middle section → lower section.

Key words: The southwestern region of Enhong block, Coalbed methane, Fluid energy characteristics, Grey relational analysis, Orderly development
