From full hydraulic engineering drilling rig spud phenomenon with full hydraulic drilling rig from drilling in production when the top drive drilling rig derrick rope rigidity and stiffness relatively close, but relatively rigid drill string is much larger, XY -2 drilling rig where to sell, so in the case does not affect the structure can be ignored and the flexible frame and rope. When fully hydraulic drilling rig in drilling production time, much more rigid top drive drilling rig derrick and rails than rigid drill string, but rigid and rigid frame larger than the rails, so do not affect the solution The results of the case, XY-2 type drilling rig equipment, you can ignore the mast and rail flexibility. Deformation of the drill string is a non-linear, ie the drill string from top to bottom circumferential angular displacement is not linear, and therefore the angular displacement of the drilling rig to drill spindle is a certain delay. Part of the lifting system from full hydraulic drilling rig is fully hydraulic drilling rig lifting system function, with other parts of the body of common components supporting sets of full hydraulic drilling rig equipment. Lifting system for full hydraulic drilling rig, the drilling process and main role is to play the next hole, casing, drill and drill bits and other hanging hold. Lifting System This system is mainly composed of drilling winches, auxiliary brake, traveling system and derrick composition. Also for the operation of the wellhead tripping drill tools and mechanization equipment. Role derrick crane is used for placement, suspension travel, hook and special tools, Quzhou XY-2 type drilling rig, operated from under the drill and lower casing during drilling. Full hydraulic drilling rig swimming system can greatly reduce the rope pull, thereby greatly reducing engineering drilling rig winch and various operations in compliance, while reducing the lifting unit should be equipped with motive power. Full hydraulic drilling rig in the role of the main winch is used to play the next hole, casing, drilling process control WOB, XY-2 type drilling rig manufacturers, feed drill and drill wire by means of unloading the drill bit buckle, lifting heavy objects, and perform other auxiliary work.
