According to the requirements of the holding point of groundwater and aquifers Shandong rig, water well drilling rig exploration process has the following holding point: ① the sleeve Tho well drilling rig with large diameter. In order to facilitate the next casing string from the well outside diameter as large boxes. In order to enhance the strength of Shandong rig casing accessories, wall thickness relatively large core drilling. ② drill using large outlet structure, less cutting tools, large alloy sheet. In order to make the fluid flow, the majority of the drill bit for the ribs. ③ well drilling rig drill diameter, is to increase the torque decreases in the drill fluid flow resistance. ④ the use of "soft reduction, slow turn, a large amount pump" procedures in the drilling process. Gently press in soft formations, rock drill rig Shandong small, light pressure can prevent broken drill 亊, therefore, to improve the stress state of the drill rig to the Shandong models to prevent hole deviation. Slowly into the technical measures to adapt the hole diameter of the well, and the use of the torque, number of revolutions of well drilling rig is between 20? 120r / min, the establishment of a number of grades, large pump shake due to the hole wall and the drill pipe annular gap, to make the hole bottom cleaned only increase firefly row to increase the flow rate between the ring cheaper to prevent debris and broken recurring accidents. Blasting rig week maintenance: ① thorough maintenance classes required for maintenance projects. ② remove dirt chuck and kava tooth surface, and soil. ③ clean the surface of the barriers holding oil, mud. ④ troubleshooting occur within the week.
