中文摘要:土耳其卡赞天然碱矿水溶采卤对接井施工项目技术规范中对工程质量的要求非常严格。由于矿区地质构造复杂、地层倾角大、含水层多等原因,易出现直井易斜、岩心采取率低、固井质量差,水平对接井轨迹控制难等问题。针对这些问题,在前期施工经验的基础上,通过调查研究、方案优选等手段,分别提出了针对性的措施,有效地解决了这些钻井难题,优化了钻井工艺,从而保证了施工质量,加快了施工进度。该项目钻井质量控制成果对于今后类似工程的施工具有一定的借鉴意义。

Quality control measurements for solution mining with intersected well sets of Kazan Trona Mine in Turkey
Abstract:The requirement on the quality control in the technical specifications is very strict for drilling of the solution mining intersected well sets at Kazan Trona Mine. The vertical wells were easily deviated, with low core recovery and poor cement bonding due to the complex geology, the high dip angle of the formation, and presence of several aquifers; meanwhile, for the horizontal well, it was very difficult to control the trajectory. After a thorough analysis of data obtained from previously drilled wells and a study of related issues and optimization of solutions, several measurements were put forward and applied. The results showed that all the drilling problems were effectively solved, the drilling process was improved, and the construction period was reduced. The experience acquired from the project could be used as reference for the similar works.
