摘要
为解决该区影响煤层气地面井的布设及提高产能问题,通过对阜新煤田煤层气地质、富集机理及刘家区煤层气地面钻井开采资料的综合分析研究,提出了该区煤层气井地面开发和高产能主要受控于煤层的埋深、岩浆岩、水文地质条件、围岩性质和构造因素的影响。并据此提出了该区选择地面煤层气井布设的井与方向。该成果对阜新煤田煤层气的开发利用具有一定的参考价值和指导意义。
In order to overcome the problems associated with the surface spatial arrangement of wells,and enhance the gas productivity,this paper investigates the geological conditions and accumulation mechanism of coal bed methane in Fuxin coal field,and analyzes the drillhole data at Liujia area.Therefore,the paper concludes that the well surface spatial arrangement and gas productivity are depended on the coal seam depth,magmatic rock,hydrogeological conditions,the properties of surrounding rock and geological structures.Based on the new findings,the spatial arrangement of gas wells is proposed in this paper.This study is useful for coal bed methane exploitation.
