煤层地面区域治理水平分支孔钻进速度影响因素探析

Analysis of Horizontal Branching Drilling Velocity Impacting Factors in Coal Seam Surface Regional Governance

近年来我国科学技术的不断发展,钻井新技术不断投入到施工中,水平分支孔技术不限于在油气施工中应用,在煤层地面区域治理中也广泛应用。新集能源公司新集二矿1煤组开采底板灰岩水地面超前区域探查治理项目,采用水平分支孔治理底板灰岩水防止水害,在已完水平分支孔施工中,不断进行技术革新和探索,总结施工经验,对影响钻井速度因素有了初步认识。提高水平分支孔钻进速度可以使钻井任务较快的完成,节省资金投入,为企业创造更多的经济效益。

With continuous development of science and technology in China recent years,new drilling technologies have been ceaselessly put into operations.The horizontal branching drilling technology is not only used in oil and gas drilling,also widely used in coal seam surface regional governance.The Xinji energy company Xinji coalmine No.2 coal group I extraction floor limestone water surface advanced regional exploration and governance project has used horizontal branching drilling to govern floor limestone water and control water hazard.In completed horizontal branching drilling operations,technical innovation and probing have been continuously carried out,and operation experience summarized,drilling speed impacting factors initially recognized.To improve horizontal branching drilling speed can quicken drilling completion,save investment;create more economic benefits for enterprise.
