煤油气共生矿井顶板油气赋存特征及防治措施研究

Research on the Characteristics of Oil and Gas Storage on the Roof of Coal Oil and Gas Symbiotic Mines and Prevention Measures

为了提高煤油气共生矿井油气灾害治理的科学性,以富县矿区为例,采用钻探取芯、物探识别、分析化验等多种方法,研究了采掘工作面煤层顶板油型气赋存特征,并探讨了顶板油型气富集的主控因素。结果表明油气主要赋存于煤层顶板3套砂体中,油气富集受到沉积相带、构造鼻隆与厚层砂体的共同控制,建议加强油型气综合探查技术、油型气灾害预测预报技术、油型气综合抽采技术和智能化矿井建设等方面的研究。

In order to improve the scientific management of oil and gas disasters in coal oil and gas symbiotic mines,taking the Fuxian mining area as an example,various methods such as drilling,geophysical identification,and analysis were used to study the occurrence characteristics of oil type gas on the roof of coal seams in the mining face,and to explore the main controlling factors for the enrichment of oil type gas on the roof.The results indicate that oil and gas mainly exist in the three sets of sand bodies on the coal seam roof,and the enrichment of oil and gas is jointly controlled by sedimentary facies zones,structural nose uplifts,and thick sand bodies.It is recommended to strengthen research on comprehensive exploration technology for oil and gas,prediction and prediction technology for oil and gas disasters,comprehensive extraction technology for oil and gas,and intelligent mine construction.
