Description

Utility model

Installation for drilling and repair of oil and gas wells

K-703MBR-160G

1. The area of technology to which the utility model belongs.

The inventive model relates to the field of engineering, to the field of lifting and drilling equipment, and more specifically to mobile units for drilling and repair of oil and gas wells.

2. The level of technology.

The design of mobile drilling rigs depends on the type of work performed, the required depth of the well and the method of drilling. Information on various designs and specifications is given in catalogs, reference books, and specialized print publications, for example, Cooper Avenue - Houston, Texas 77064 USA Gas and Oil Well Drilling Aids, Wilson Avenue - Self-propelled Drilling, Overhaul, and Well Maintenance Installations Houston, Texas 77251-1489 USA; Drilling magazines No. 2, 10, 11 for 2001, No. 3 for 2002

There are various designs of units manufactured abroad by Cooper, Wilson, mobile drilling rigs that are manufactured in Russia - Izhdril CJSC, Volgograd Plant

Drilling equipment (LLC VZBT).

All of them are equipped with a mechanical drive of winches.

The difference of the claimed utility model is the ability to control the speed of rotation of the winch drum, and, consequently, to smoothly feed the tool to the face. In domestic engineering, the nominal carrying capacity of mobile units does not exceed 125 tons.

In developing the installation for drilling and repairing oil and gas wells K-703MBR-160G with a rated carrying capacity of 160 tons, materials were used for the K-703 MTP-127G, K-703 MTU-80VGR lifting rigs, as well as K-703 MTU 60 / 80G ( patent No. 41258 OJSC Spetsmash).

3. The essence of the claimed utility model.

Soup1, the claimed utility model, The installation for drilling and repairing oil and gas wells K-703 MBR-160G consists in the fact that the installation has a hydraulic winch with adjustable pumps, which allows you to steplessly change the speed and flow of the tool, and therefore get the most optimal operating mode and land; significantly increase drilling productivity.

drilling one of the pumps is switched on for the operation of the drilling rotor, and the second provides the winch.

Description of the useless model

The operation of the installation for drilling and repairing oil and gas wells during rotary drilling: the installation is deployed at the well, the tower 2 rises to the vertical position and its second section extends, the chassis 1 is hung on the hydraulic jacks 17, the tower 2 is strengthened by power and wind cables, along the axis a fixed working platform 8 is installed on the well, on which a beam with a rotor 16 is mounted. Next to the installation for drilling and repairing oil and gas wells, a drill block 11 and a circulation system 12 are installed. Application osnash; aetsya drilling riser 13 with hose 15 and swivel.

The drilling process begins. Drilling can be carried out with hydraulic tool 1ent: rotor, top power drive or swivel. At the same time, the pumping station of the drilling rig is used to rotate the hydraulic drive tool.
