In order to better explore oil and some other products, people need tools to help themselves to complete the drilling work, in order to meet the development of China's oil and industry, China's oil drilling rig development is also advancing with the times, for China's drilling work to provide convenience, oil drilling equipment mainly contains what:
Drilling equipment and tools include surface drilling equipment (oil rigs), drill bits, drill strings, etc.
1. oil rig
1. Composition of drilling rigs Modern oil drilling rigs are a set of large combined units. According to the requirements of drilling, flushing, lifting and tripping of drilling tools in the drilling process, a set of drilling rig shall be equipped with the following systems and equipment:
Drilling Equipment
(1) Lifting system. It is used for lifting and running drilling tools, replacing drill bits and running casing.
(2) Rotary system. It is used to drive the drilling tool to rotate, break the rock and deepen the borehole.
(3) the circulation system. It is used to circulate drilling fluid to clean the bottom of the well and carry out broken rock cuttings to ensure continuous drilling.
(4) Power equipment. The power equipment for driving drawworks, rotary table, drilling pump and other working machines are mostly diesel engines, and some drilling machines are driven by AC or DC motors.
(5) transmission system. The main task is to transfer and distribute the energy of the power equipment to the working machines.
(6) Control system. In order to command the various systems to work in a coordinated manner, the rig is also equipped with a variety of control equipment, such as mechanical, hydraulic or electrical control devices, equipped with a centralized console and observation and recording instruments.
(7) Base. Including drill floor base, machine room base and drilling pump base.
(8) Auxiliary equipment. Generally, it includes wellhead blowout preventer, air compression equipment, auxiliary power generation equipment, auxiliary lifting equipment, wellhead tools and movable houses.
2. Wellhead tools Manual wellhead tools such as tongs, elevator and slips are required for lifting and lowering the drilling tools and for screwing and unloading the drilling tools.
The tongs are composed of several tongs with dental plates and a tongs handle, which are connected to each other by hinges. The tongs are used to unscrew the connecting threads of various downhole tools that make up the drill string, such as drill pipe and drill collar. The tongs are used in pairs of inner and outer pairs (one positive and one negative), and are screwed with a cat's head rope.
The elevator is used to suspend, lift and lower the drill string. The inner diameter of the elevator is slightly larger than the outer diameter of the drill pipe, but smaller than the outer diameter of the drill pipe joint. Clamp the drill string joint while working for tripping and tripping.
When the drill string is screwed on or unscrewed, the section of the drill string located in the well shall be temporarily suspended from the rotary table. The slips installed in the hub of the rotary table are used to hold the drill pipe and suspend the drill string.
With the rapid increase in the number of deep wells, hard formations and offshore drilling, the workload of up and down drilling operations is obviously increasing. Using the above-mentioned manual wellhead tools to unscrew the thread is physically intensive and has low work efficiency, which urgently needs to be improved. At present, there are many forms of power tongs and power slips used in drilling production. Speed up the speed of up and down, reduce the labor intensity of workers,.
The further realization of the drilling work of the overall mechanization, automation laid the foundation.
3. The blowout may occur when the wellhead BOP is drilled through the high-pressure oil and gas layer, causing serious problems. In order to control the injection of drilling fluid, oil, gas and water in the well when blowout occurs, a blowout preventer is usually installed under the drill floor. At present, the drilling rigs produced at home and abroad are equipped with a complete set of blowout preventer system.
