JACK SUPPORT FOR SYSTEM FOR DERRICK-DRAWWORKS UNIT OF DRILLING RIG MOVING AND SYSTEM FOR DERRICK-DRAWWORKS UNIT OF DRILLING RIG MOVING

摘要

FIELD: mining.;SUBSTANCE: system for moving derrick-drawworks unit of cluster drilling rig for drilling wells installed on derrick sub-structure includes substructures connected to derrick sub-structure and at least for jack supports connected to derrick substructure. Jack support of movement system includes supporting mat on the surface of which there are not less than two rails, hydraulic cylinder of horizontal movement and hydraulic cylinder of vertical movement with cylinder support, trolley with the possibility of supporting mat rotation round the vertical axis, rail clamps with cylindrical rollers connected to the trolley.;EFFECT: increase of drilling works efficiency within multiple-well platform, reduction of total construction time of multiple wells and multiple-well platform construction and preparation costs.;10 cl, 12 dwg
