| 中文摘要:以山东肥城海晶盐化有限公司100万t/a卤折盐采输卤工程钻井项目中H17/H18对接井为例，首先介绍了定向钻进对接技术在采卤井中的应用以及定向钻孔轨迹设计，在对地层详细勘探的基础上对定向钻孔进行可靠精确的轨迹设计是钻探施工的基础。其次，介绍了定向水平井的施工工艺。本项目关键技术是MWD无线测斜仪技术和旋转磁铁测距系统（RMRS），以及钻进时钻井液选取和参数调控。MWD无线测斜仪技术和旋转磁铁测距系统（RMRS）可以实时测量钻进方向，进而根据工程需要调整钻进方向，保证了中靶作业成功连通。本项目施工过程中的难点及所采取的技术对策可为同类钻井施工提供借鉴和指导依据。 |

| Abstract:With the case of H17/H18 butt well in brine transportation project of a salt and chemical company in Shandong, the paper introduces the application of directional drilling and butting technology for brine wells and the design of directional drilling trajectory, which is based on the detailed formations exploration; and also introduces the construction technology of directional horizontal well. For this project, the key technologies are drilling fluid selection and parameter control in the drilling process; and what''s more, MWD inclinometer technology and rotating magnet ranging system (RMRS) are used to measure the real-time drilling direction and then adjust the drilling direction according to the needs of the project in order to ensure the successful well butting. The difficulties in this project construction process and the technical countermeasures can be reference for the similar drilling construction. |
