Technical complexes for sinking sedimentary rocks

摘要

The proposal relates to the mining industry. Tehkompleks includes downhole equipment in the form of preventer with shut-off and control valves; handling equipment, a control unit. The drilling unit is in the form of energetically autonomous vehicle in its single housing 1 has modular units, which are mainly designed device for working agents: termogazogeneratory 2 and 3, equipped with a common source 4 fuel chemical components and one gazovytesnyayuschim device 5 placed between termogazogeneratorami , working chambers which are connected to, are constructed as cutter working member 6 to 7 gas-jet devices vapor-gas flow composition mixture, 8, and Mechanical Protection nozzles 9, and as an additional operating element 10 with gas jet nozzles 11, designed to create a rising flow of drill cuttings and drilling unit for supplying to the face 12 and - to the wellhead 13. The generators 2 and 3 are provided with two chambers 14 and 15 initiator 16 heating the mixture and its thermal decomposition. The unit is a universal drilling machine for penetration of various breeds. IL. - 4; forms. - 3 n.
