Purpose:
Drilling rig PAP-80/100 is designed for oil & gas well-workover operations and for work as a part of mobile drilling complex with load on hook up to 100 tons.
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;
- milling of the metallic parts of drilling equipment fallen into the well;
- well development after drilling completion.
Design features:
- mobile moving from well to well;
- increased angle lean of derrick allows to work at well clusters with pipes outbreak at 90° relative to longitudinal axis of rig;
- mono derrick of extended hardness;
- rig` axles load and transport dimensions do not exceed allowed regulations for public road travel;
- emergency drive, operating on electric engine of lifting rigs` all units and allowing to operate by main engine failure, is provided;
- drum with hoist wireline stock for bypass is installed;
- separate assembly & working hydrosystems improve reliability of rig;
- single drum drawworks with disc air clutches and water cooling disc brakes.
