摘要：

基于沁水盆地柿庄南区块23口排采1年以上的煤层气井排采水水质分析数据及实测储层压力，采用Schoeller图、Piper图等分析了柿庄南煤层气井排采水地球化学特征及水动力分区特征，探讨了水文地质条件对煤层气富集的影响。研究表明柿庄南区块煤层气井排采水主要为Na_HCO3水型，反映研究区处于开启_半封闭的水文地质环境；排采水氢氧同位素值均位于全国大气降水线附近，排采水初始来源主要为大气降水；利用折算水位将研究区大致划分为西北部径流区、南部弱径流区及中部过渡带滞流区，水流从西北部和南部向中部滞流区汇聚，水化学参数反映出滞流区煤层气保存条件好于两侧径流区和弱径流区。基于水化学场和水动力场参数建立了煤层气富集区优选指标体系，优选出煤层气富集有利区和较有利区，对下一步煤层气井布置具有指导作用。

Abstract:

Based on the measured reservoir pressure and the water quality analysis data of 23 CBM wells drainaging more than 1 year in Shizhuangnan block，hydrogeological and hydrodynamic characteristics were studied using multi-methods such as Schoeller counter，Piper counter，and the influence of hydrogeological conditions on coalbed methane enrichment was discussed.The study indicated that the drainage water is mainly Na-HCO3 type which reflects the study area was in an open-semi closed hydrogeological environment，the hydrogen and oxygen isotopic values of drainage located near the national atmospheric precipitation line and proved that the initial source of drainage water was atmospheric precipitation.The study area was divided into runoff area in the northwest，weak runoff area in the south and the stagnant wake in the central area using conversion water level，and the water came from the northwest and south and flew into the stagnation zone.Hydrochemical parameters reflect the preservation condition in the stagnation zone are better than that in the runoff area and weak runoff area at both sides.Based on the parameters of hydrodynamic field and hydrochemical field，the parameter system of CBM favorable area optimization was established，and the favorable good target was selected using this system，and it gave a guide for the next CBM well layout.
