中国煤层气第四期 彬长矿区煤层气勘探开发潜力分析 张康顺 陈龙 钱建峰 熊鹏辉 徐建民 索根喜 （陕西省煤层气开发利用有限公司，陕西西安 710065 ） 摘要：彬长矿区位于鄂尔多斯盆地东缘，是我国煤层气研究和勘探最早的地区之一。该区煤 层气资源丰富，预测资源量可达 153 亿 m3 ，具有巨大的开发利用前景。本文在分析总结前 期工作的基础上，对该区煤层气勘探开发潜力进行了分析研究。认为彬长矿区煤层气富集特 征明显、构造稳定简单、煤层厚度较大、含气量较高、埋藏浅、储层物性较好，具有良好的 开发潜力。 关键词：彬长矿区 煤层发育特征 煤层气 开发潜力 Analysis on CBM ED Potential in Binchang Mining Area ZHANG Kangshun, CHENG Long, QIAN Jianfeng, XIONG Penghui, XU Jianmin, SUO Genxi (Shaanxi Coalbed Methane Development Company Limited，Shaanxi 710065) Abstract: Binchang mining area, which is located in the eastern edge of Ordos Basin, is one of the areas where CBM research and exploration were conducted in the earliest time. This region is 3 of abundant CBM resource, which is predicted up to 15.3 billion m , so that there are great prospects for CBM development and utilization. Based on the analysis and summary of the previous works, this paper analyzes the potential of CBM exploration and development in Binchang Mining, proposes that the CBM resources in this area are characterized with obvious enrichment, stable and simple structure, large coal seam thickness, high gas content, shallow and good reservoir, and proves that there is good potential in CBM development. Keywords: Binchang Mining Area; development characteristics of coal seam; coalbed methane; exploitation potential 煤层气井排采动态预警方法研究 王凤林，胡爱梅，陈松鹤，冯 ，赵增平 堃 （中联煤层气国家工程研究中心有限责任公司，北京 100095 ） 摘要：连续、稳定排采对煤层气井生产至关重要，任何影响因素的弱化和滞后都会影响到煤 层气井的整体排采效果。本文系统分析煤层气井排采动态预警的 3 种方法：指标预警、规划 预警和趋势预警，开发了指标预警系统，在示范区应用效果良好，为煤层气田开发动态预警 提供了一条新的途径。 关键词：煤层气 排采异常 动态预警 预警系统 Study on Dynamic Early Warning Methods
