What are the main equipment of oil drilling rig? What is the working principle?
Here's an example of an oil rig.
In the oil drilling, drive the drilling tool to break the rock, drilling into the ground, drilling out the specified depth hole, for the oil or gas extraction machine or gas.
Oil rig there are eight major general system (lifting system, rotation system, drilling fluid circulation system, transmission system, control system and monitor display instrument, power drive system, rig substructure, drill auxiliary equipment system), to have a trip, rotary drilling, circulating to wash well. The main equipment are: derrick, crown, winch, travelling block, hook, turntable, faucet (power swivel) and drilling pump (eight) field traditionally called drill, the engine (diesel engine, electric motor, gas turbine), interlocking machine, solids control equipment, well control equipment, etc.
The working principle of drilling rig is rings and rings with pin connection between, the suspension loop with hook rod welding as a body, cylinder and a hook with left-hand thread connection, and stop block to prevent thread is loose. The hook and barrel can move along the hook rod. The internal and external load spring can be used to lift the upright roots and spring up.
The whole body is fitted with motor oil. The seat ring of thrust bearing divides the oil chamber into two parts, with oil holes in the seat ring. Because of the damping effect of oil flowing through, it absorbs the shock vibration of the hook during the drilling operation, which can prevent the damage of the street thread of the drill pipe.
Tower top is composed of six small spring and positioning plate positioning device, with the aid of positioning and friction between the rings seat ring contact surface, can prevent ascension empty when the elevator turn turn a switch, convenient derrickmen operation.
The above is about the detailed content of oil drilling rig, want to learn more relevant information, please pay attention to the real-time update in the station.
