摘要
为了分析煤矿采动区对邻近煤层气井的产能影响,对樊庄区块西南部煤层气井的物性特征和产能特征进行了研究。研究表明:随着距煤矿采动区距离的增加,煤层的含气量逐渐增大,渗透率逐渐下降;根据采动区邻近煤层渗透率变化和煤层气井的产能特征,将采动区周围区域划分为4个区域,并提出了产能控制模式。煤炭和煤层气协调开发过程中,建议在Ⅱ、Ⅲ区布置煤层气井,有利于煤层气的高效开发。
In order to analyze the influence of mine mining area on the capacity of adjacent coalbed methane （CBM） wells, the physical properties and productivity characteristics of CBM wells in the southwest of Fanzhuang block are studied. The results show that with the increase of the distance from the coal mining area, the gas content of coal seam increases gradually, and the permeability decreases gradually; according to the change of coal seam permeability and productivity of CBM wells, the surrounding area of coal mining area is divided into four area, and put forward the capacity control mode. In the coordinated development process of coal and CBM, it is suggested to arrange CBM well in Ⅱ and Ⅲ area, which is beneficial to the efficient development of CBM.
