Study on relationship of liquid energy distribution and coalbed methane development in coal bearing strata

From the reservoir pressure water dynanic condition and gas beaing aspects ,a comprehensive analysis was conducted on the vertical distrbution features of th lauid energy in Shuigonghe syneline Late Pemian coal beaing strata of Wlest Guiznou Due to the sedimentary environment dferences,three coal bearing sections had ohviou diffrental n the liquid energy The energy condtion at thecentral secion was best the top secion was second and the bottom section was poor.The the secions formed thee independent coabed methane beaing systems and there wa lack of the interaction lcuid connecton.Thus the coal bearing stratum wasdivided into the top.,midtle and boton development sectons and the sequence development mode of the calbed methane from the top to the bottonm in sequence wasaplied to the thee develogment sections with the sectional downward development.The area had the engineering geological conitions for the coalbed nethane surace development and the mutit stata fracturing combined nining fechnology with the verical wells would be based. The horizontal well echnology could be applied to N0.5-3seam,No.6-3seam and No.8 seam and the cluster well technology would have a good promotion prospect.
