分析受控定向孔在铜陵凤凰山矿区的实践

The Practice of Branching Controlled Directional Drilling in Fenghuangshan Coal Mine Area of Tongling

施工分支受控定向钻孔比其他方法更优越、更先进,成功地解决了常规钻进难以实现的问题。本工程采用一主二支集合孔的方式施工,不仅对深部矿体适用定向钻探勘探提供了可行性论证,而且为我国全面受控定向钻探技术得到广泛应用开辟了一条新路。本文概略地介绍了所取得的技术、经济效果及所采用的定向钻探技术方法。

Controlled directional drilling in construction is more advantageous and advanced than other ways,and it can succe-ssfully overcome the difficulty in common drillings.The method used in this construction is not only a feasible prove for contr-olled directional drilling,but open up a new way for the broad use of controlled directional drilling technology.This paper bri-efly introduces the technology we acquired,the economic benefit we got and the ways of utilizing controlled directional drilling.
