废弃裸眼油井封堵治理方法应用
|
摘要
本文论述了废弃油井对煤矿开采的影响及废弃裸眼石油井的封堵技术,并以双马煤矿废弃未封堵的或封堵不良的废弃油井为例,通过井口查找、开挖、透孔、水泥封堵、加压验封等工程措施,完成废弃油井地面封堵治理工程。结果表明,I0104105工作面在回采期间,不会受到该废弃油井的影响而出现涌水量异常、有害气体超限涌出等现象,切断了危险源来源,确保了工作面的安全回采。
This paper discusses the influence of abandoned oil wells on coal mining and the plugging technology of abandoned open hole oil wells. Taking abandoned oil wells that abandoned but not plugging or the undesirable abandoned wells in Shuangma Coal Mine as an example,the surface plugging treatment project of abandoned oil wells is completed through well head searching,excavation,perforation,cement plugging,pressurized seal inspection and other engineering measures. The results show that the water discharge is ab-normal and the harmful gas is out of the limit in the working face I0104105,which will not be affected bythe abandoned oil well during the mining period,thus cutting off the source of danger and ensuring the safe mining of the working face.
