The invention relates to the drilling technique, namely, mobile drilling rigs with high cross, intended for deep drilling, maintenance and repair of wells.Known mobile oilfield installation comprising a transport base, a tower with a lifting mechanism (see the description izobretena dimensions of the shelter, and the limited height of the tower does not allow deep drilling installation. In addition, work on the Assembly - disassembly shelter installation is time-consuming, which reduces the efficiency of its use.The closest but the achieved technical result, taken as a prototype, is a mobile repair drilling unit (see the description of the invention to the patent of the Russian Federation 2162133, IPC E 21 7/02 from 28.03.2000 g) containing a multi-axle chassis, horizontally disposed on the frame in the transport position, the oil rig, the device for lifting a tower in a vertical operating position, the support jacks with tareley for leveling.Constructive design of the unit provides deep drilling, however, allows the setting of several rigs using one of the transport base: the tower attached to the chassis. The use of the known drilling unit increases the time field development in terms of the sectional arrangement of the wells due to the mounting and dismantling of the tower. In addition, the use of pulley system reduces reliability.The invention solves the problem of reducing the time and complexity to the Assembly-disassembly of Batali installation.To achieve a technical result of the proposed mobile drilling rig containing a multi-axle chassis, horizontally disposed on the frame in the transport position, the oil rig, the device for lifting a tower in a vertical operating position, the support jacks with tareley for leveling, according to the invention, the device for lifting a tower equipped with a console platform hinged to the frame, while the tower is made removable and is connected to the console platform, at least three vzaimootmenyaemy catching type hook-loop orientation and fixation of the tower, zamorozhennye upright tower when installing it on the ground, with two hooks are located at the free end of the cantilever platform, symmetrically to the longitudinal axis of the tower, the third side console mounting platform to the frame, and the base of the tower is equipped with at least four legs, mounted with a possibility of rotation and fixation in the working and transport positions.The hooks are made flat with maw, provided with a safety groove.Zev made prismatic or parabolic shape. The locking groove is placed at the base of a prism or of a parabola.Each tx2">The cross-section of the locking groove is made mating with the locking groove of the hook.The free end of each foot is equipped with a hydraulic cylinder with a plate for leveling removable tower.The piston of the hydraulic cylinder is made with two rods, one of which is equipped with a safety element.Mobile drilling rig is equipped with an additional self-propelled platform with a console platform for service rigs, hinged can be locked in the tower free end, a manipulator, a control system, pumping station, rack - drive for the drill pipe.Distinctive features of the proposed mobile drilling rig from the well-known, is the implementation of the HSE removable, for which the rig and platform device for lifting are connected by at least three vzaimootmenyaemy catching type hook-loop orientation and fixation of the tower, zamorozhennye in a vertical position. The base of the tower is equipped with at least four power jacks, mounted with a possibility of rotation and fixation in the working and transport positions. For the viability of a mobile drilling rig, it is equipped with extra samaha and on the rig free end, a manipulator, a control system, pumping station rack-drive for the drill pipe.The implementation of the HSE removable allows in terms of cluster location of wells to use the vehicle to transport several towers of similar design during operation of the first tower. Derrick made whole not telescopic, allowing to reduce the time of Assembly-disassembly and improve the reliability of the structure during operation of the installation.Mobile drilling rig is illustrated by drawings, where
