Purpose:
Drilling and repair of oil-and-gas wells.
Operations performed:
- mobile moving from well to well;
- assembly and disassembly of control head with the main and auxiliary hoist;
- round trip with sucker rods, tubing and drill pipes;
- mechanized spinning-up and uncoupling of tubing and drill pipes;
- construction of cement bridging in holes through derrick manifold;
- drilling-out of sand plugs and cement bridging with the help of mechanical or hydraulic drive rotary;
- fishing and other works;
- flushing-out of wells through the derrick manifold;
- breakdown elimination;
- well drilling by rotor with mechanical drive;
- kickoff and drilling of second stems;
- milling of the metallic parts of drilling equipment fallen into the well;
- well development after drilling completion.
Design features and advantages:
- drawworks is equipped with cable layer that provides uniform wire winding;
- flange for connection of drawworks emergency drive is provided;
- chassis engine emergency stop from operator’s control or remote control console;
- extension of the derrick upper section is performed by hydraulic driven winch from the remote control console;
- hydraulic driven winch is used for auxiliary works;
- double action hydraulic jacks for leveling the rig;
- reverse reducer of rotor drive is installed;
- air brake for drive rotor is provided;
- drawworks chain drive is in the closed oil bath;
- hydraulic system is dual-profiled:
1-profile is designed for carrying out auxiliary operations (rig hoisting, derrick lifting, derrick upper section moving-up, hydraulic control valve operation, auxiliary drawworks operation)
2-profile - hydraulic rotor operation, hydraulic wrench operation.
