摘　　要：为了研究煤矿工作面附近油气井泄漏情况,采用对比分析法,在煤矿工作面附近的油气井、井下工作面附近巷道和采空区中采集了一定量的气体样品,进行了气体组分研究和碳同位素分析研究。研究表明,在试验区域,通过气体组分难以判断油气井是否向煤矿工作面发生泄漏;甲烷碳同位素值测定方法为临近煤矿工作面的油气井泄漏监测的有效技术。In order to study condition of oil and gas well leakage near the coal mining face,a certain amount of gas samples were collected from the oil and gas well near the coal mining face,the roadway and goaf near the underground working face.The gas composition research and carbon isotope analysis were performed.In the test area,studies have shown that it is difficult to determine whether a gas well leaks to a coal mine working face by gas composition;the method for measuring the carbon isotope value of methane is an effective technique for oil and gas well leakage monitoring near a coal mining face.
