  • 摘要

    排采设备的选取对于煤层气井排采效果影响较大,彬长矿区煤层气资源丰富,属于国家“十二五”规划建设的特大型现代化矿井,为提高煤层气的抽采率,在分析排采设备的适应性及影响因素的基础上,结合彬长矿区的地质情况和排采数据等,利用参数量化综合评价法进行排采设备优选,结果表明:彬长矿区最佳的排采方式为有杆泵,抽油泵选取ø38 mm管式泵,同时考虑静载荷、冲程和转矩等影响,经过悬点载荷公式计算,计算结果表明:当井深400~600 m时,选择CYJ4-1.5-9型抽油机;当井深600~1 000 m时,选择CYJ5-2.1-13型抽油机,抽油杆选取D级ø19 mm,在后续排采实践中应用效果较好,研究成果可为彬长矿区煤层气排采设备选取提供一定的技术支撑。

  • Abstract
    The selection of drainage equipment has great influence on the drainage effect of coalbed methane wells. Binchang Mining Area is rich in CBM resources and belongs to the ultra-large moderm mine under the national“Twelth Five-Year Plan" .In order to improve the extraction rate of coalbed methane ( CBM ) ,on the basis of analyzing the adaptability and influencing factors of the mining equipment and combining the geological conditions and drainage data of Binchang Mining Area, the parameter quantification comprehensive evaluation method is used to optimize the drainage equipment. The results show that the best drainage method in Binchang Mining Area is by rod pump, with the selection of 038 mm tube pump.Considering the ffctst of static load , stroke and torque , the calculation of suspension load formula shows that well depth is 400~ 600 m, the CYJ4- 1.5-9 pumping unit is selected; when the well depth ranges from 600 to 1 000m, the CYJ5-2.1- 13 pumping unit should be chosen , sucker rod should employ the D grade 019 mm, and the application effect is pretty good in the practice of subsequent mining.The research results can provide certain technical support for the selection of calbed methane drainage and mining equipment in Binchang Mining Area in the future.
