Composition of rig equipment

Lifting system
Composition: derrick, winch, swimming system, wire rope, crane , traveling crane,  big hook;
Role: to play drill, casing, control drill and drill.
Rotary system
Composition: turntable, square drill pipe,  drill string faucet, top drive system, downhole power drilling tools, etc.
Role: Drive drilling tools, drill bits and other rotating broken rocks , loading and unloading drill tools , special operations (connecting the lifting and mud circulation system).
Circulatory system
Composition: vibrating screen, sand remover, desilter
Role: circulating mud fluid
power system
Composition: motor and diesel engine, etc.
Function: To drive the working machine such as winch, turntable, drilling pump, etc.
Transmission system
Composition: reducer, clutch, shaft, chain, etc.
Role: The main task of the transmission system is to transfer and distribute the energy of the engine to each working machine. Due to the gap between the characteristics of the engine and those required by the working machine, the transmission system must include mechanisms such as deceleration, parallel running, reverse rotation, and speed change. Sometimes on the basis of mechanical transmission, there are also hydraulic transmission or electric transmission.
Control System
Composition: computer, sensor, signal transmission medium, control actuator, etc.
Role: Coordinate the work of various systems. According to the requirements of drilling technology, each working machine can respond quickly, operate accurately and reliably, and facilitate centralized control and automatic recording. Enables the operator to ensure the safety or normal work of the components of the rig according to his own wishes.
Base
Composition: The rig base is mainly composed of the rig base, the pump base and the two main auxiliary equipment bases, etc., which are generally made of steel pipe welding.
Role: It is convenient to install various equipment of fixed drilling rig to meet the requirements of relocation or towing construction. The deep well drilling rig should also be beneficial to install wellhead blowout prevention facilities and facilitate personnel operation and maintenance.
Auxiliary equipment
Modern rigs must also have a set of auxiliary equipment, such as power supply, gas supply, water supply, oil supply and other equipment, equipment storage, blowout and fire prevention facilities, drilling fluid preparation, storage, processing facilities, and various instruments and automatic recording instruments. Workers in remote areas need to have facilities for living and rest. In order to communicate, communication equipment such as telephones, radios, and walkie-talkies are also required. Heating and insulation equipment is needed for drilling in cold areas.
