中文摘要:土耳其是世界上最早应用定向对接井进行天然碱商业化开采的国家,其所使用的核心技术——对接井水溶开采技术,就是引进我国自主研发的定向水平对接井水溶开采技术。与常规旱采方法相比,该技术具有劳动强度低、人工成本少、不排放尾矿、绿色环保等优点。在过去10多年里,我国以对接井水溶开采技术为依托,深度参与了土耳其贝帕扎里和卡赞两大碱矿从试验到生产的开发,在整个工程实施过程中持续对开采井组模式、定向器具、井底钻具总成、测井仪器等进行了改进,尤其是磁中靶系统方面取得了突出成果和广泛应用,开发了第四代“慧磁”钻井中靶导向系统,设计施工了三井组模式。一方面,通过该项技术的应用使土耳其天然碱资源得到广泛开发,其纯碱工业在世界上占有了一席之地;另一方面,通过广泛的生产实践进一步推动了定向钻探技术的发展,提升了我国定向水平对接井技术水平。

Review on trona solution mining with intersected well sets in Turkey
Abstract:Turkey is the first country to extract trona deposit commercially with intersected well sets. The core technology which is employed to make underground connection of the well sets for brine recovery is the intersected well drilling and mining technology developed by China. Compared with conventional tunnel mining, mining with the intersection well sets provide lots of advantages such as less labour intensity, reduced labour cost, environment soundness without discharge of tailings. In the past ten odd years, with support of the intersected well drilling technology, China has participated extensively in test and commercial production of trona resources, and made continuous improvement on the mining well set design, orientation tools, BHAs, survey tools; in particular, great achievement has been made in development and application of the magnetic ranging system, with the 4th generation “SmartMag” ranging tool launched into market; meanwhile, the three well set mining mode has been desgined and implemented. On one hand, intersected well drilling and mining technology has driven the extensive exploitation of trona resources in Turkey to elevate it to a major player in the world soda ash industry; on the other hand, intersected well drilling and mining technology has advanced itself through intensive field application, lifting it to a higher level.
