The rig uses modern automatic drilling control and advanced offshore drilling technology. Including the single-seat driller cabin, the driller sits in the air-conditioned room through the programming logic circuit, the screen and the joystick remote control winch, turntable, drilling pump and thyristor rectifier; also uses steady-state electronic drilling device to carry out various related functions and drills. The combination of pressure, footage speed, pump pressure change, and turntable torque allows the driller to apply stable drilling pressure without manual control of drilling time. It can also be connected to the disc brakes via the encoder on the winch and the proximity sensor on the derrick. The proximity sensor also ensures safety and closes the hoist system once the ride is too close to the crown or drill floor.
These rigs can be handled in three ways: one is to sell on the market at a lower price; the other is to invest these rigs in oil fields, which can greatly increase domestic drilling activities and reduce the economic burden of oilfield users; The amount is increased, and these rigs are technically transformed and modernized. The current number of backlog rigs continues to decline.
Due to the oil price hike and the maintenance of oil wells, the US land workover machine market activity has increased in the past two years. This year, the workover rig increased by 31% to 1,350 units. In 2002, it is expected to increase by 10% to 1,491 units. This is based on the average oil price increase of $27 a barrel, and the oil well requires more maintenance. In recent years, drilling in the United States has tended to be deeper in gas wells. The workover rig has a great effect on the completion and stimulation of these deeper wells, and the workover of these wells is increasing, and the workover activities of the wells are greatly rebounded. A notable feature of this patented technology is the breaking of the conventional use of an external blower to cool the internal coils, using natural gas to achieve internal coil cooling.
