Construction technology of the 3000m scientific drilling project in Dayingezhuang,Zhaoyuan County,Shandong Province
摘要
Abstract
The 3000m scientific drilling project of Dayingezhuang in Zhaoyuan,Shandong Province is the deepest scientific drilling project in the Zhaoping fault zone in Jiaodong area,with a design drilling depth of 3000m.In order to improve the drilling construction efficiency and reduce the probability of accidents in the hole,the project adopts an efficient and stable XY-9DB variable frequency drill rig,self-developed high-efficiency long-life diamond drill bit,CHD76 series high-strength drill pipe and jointly developed LZRT360 drilling fluid centrifuge.The key technologies such as P/H wire-line coring hydraulic percussion drilling technology and wire coring coating drag-reducing inner pipe technology are adopted to carry out deep hole drilling construction,and the rinsing fluid system is optimized for different strata.The final hole depth of the project is 3120.35m,the final hole diameter is 78mm,the average core recovery rate is 95.6%,and the average core recovery rate is 97.9%.This paper summarizes the treatment methods,solutions,and equipment usage of complex formation drilling in the construction process of this project,aiming to provide references for similar deep drilling projects.关键词
