The basic structure of electric earth augers

Electric earth auger is a rapidly developing type of drilling rig today, which has a high price and high performance and is suitable for drilling and construction of various oil and gas wells.

The electric earth auger mainly consists of the following systems: power system, electric transmission system, lifting system, rotary system, mud circulation system, liquid gas control system, oil supply, and water supply system, drilling parameter detection, processing and transmission system, wellhead workers, and auxiliary facilities.

1、 Powertrain

The power system consists of a diesel generator set and an auxiliary diesel generator set. Electric drilling rigs can also be powered by grid electricity. The diesel generator set can be arbitrarily connected to the grid for operation and load-balanced distribution as required.

2、 Electric drive system

The electric drive system consists of an SCR or VFD system and an MCC. SCR or VFD systems supply power and control the motors that drive the winch, drilling pump, and rotary table, and their characteristics meet the working requirements of the winch, rotary table, and drilling pump. Power and control low-voltage AC motors, lighting systems, living lanes, and other AC electrical equipment.

3、 Lifting system

The lifting system mainly includes a winch, crown block, traveling block, hook, wire rope, derrick, substructure, lifting ring, elevator, and other tools used for auxiliary drilling operations. Its function: to realize tripping the drilling tool, tripping the casing string, and controlling the bit feed.

4、 Rotating system

The rotary system consists of a rotary table and faucet (or a top-driven drilling unit). Its function: rotating the drilling tool and circulating mud.

5、 Mud circulation system

The mud circulation system consists of a drilling pump, a high-pressure manifold, a mud tank, and mud purification equipment. Used for circulating and purifying mud to ensure continuous drilling operations.

6、 Liquid gas control system

The hydraulic and pneumatic control system consists of a hydraulic station, a gas source and purification device, a control valve, a control pipeline, and an actuator. The hydraulic and pneumatic control system together with the electric transmission system realizes the control of the entire drilling rig.

7、 Drilling parameter detection and transmission system

Drilling parameter detection and transmission systems typically consist of sensor signal processors, display recorders, alarms, well-site transmission systems, and remote transmission systems. It can detect, record, process, transmit, and remotely manage the relevant parameters of the entire cobalt well process.

8、 Oil and water supply system

The oil supply system consists of two parts: diesel oil supply and lubricating oil supply. It is composed of oil tanks, oil transfer pumps, etc., and is used for the storage and transportation of oil. The water supply system consists of water tanks, pumps, and water pipelines. Used for cooling equipment.
