1. The composition of the hoisting system: derrick, winch, traveling system, wire rope, crane, traveling block, hook;
Function: Trigger and run the drilling tool, run the casing, control the drill bit and the drilling tool.
2. Rotary system composition: turntable, kelly, drill string tap, top drive system, downhole power drilling tools, etc.
Function: Drive drilling tools, drill bits, etc. to rotate and break rocks, load and unload drilling tool threads, special operations (connect lifting and mud circulation systems).
3. Circulation system composition: vibrating screen, desander, desilter
Function: circulating mud
4. Power system composition: motor and diesel engine, etc.
Function: Drive winches, turntables, drilling pumps and other working machines to run.
5. Transmission system composition: reducer, clutch, shaft, chain, etc.
Function: The main task of the transmission system is to transmit and distribute the energy of the engine to each working machine. Due to the gap between the characteristics of the engine and the characteristics required by the working machine, it is required that the transmission system must include mechanisms such as deceleration, paralleling, reversing, and shifting. Sometimes on the basis of mechanical transmission, there are also hydraulic transmission or electric transmission.
6. Control system composition: computer, sensor, signal transmission medium, control actuator, etc.
Function: Manipulate various systems to coordinate work. According to the requirements of the drilling process, each working machine has a quick response, accurate and reliable movements, and is convenient for centralized control and automatic recording. It enables the operator to ensure the safety or normal operation of each part of the drilling rig according to his wishes.
7. Composition of base: The base of the drilling rig is mainly composed of the base of the drilling floor, the base of the pump and the double main auxiliary equipment, etc., which are generally welded by steel pipes.
Function: It is convenient to install various equipment for fixing the drilling rig, and meet the requirements of relocation or whole towing construction.
8. Auxiliary equipment Modern drilling 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 prevention and fire prevention facilities, drilling fluid preparation, storage, processing facilities, etc., as well as various instruments and equipment. Automatically record meters. Drilling in remote areas also requires living and rest facilities for staff, and communication equipment such as telephones, radios, and walkie-talkies for communication. Drilling in cold areas should also have heating and thermal insulation equipment.
