The STD5100TLG Continuous Tubing Work Vehicle is a specialized oilfield workover rig manufactured by Hubei Luke Special Automobile Co., Ltd. The following is a detailed introduction:
Basic Information: The announced model is STD5100TLG, brand is Casarte, and chassis model is EQ2180GSZ6DJ. The overall dimensions are 6950mm in length, 2500mm in width, and 3900mm in height, with a wheelbase of 3950mm. The gross vehicle weight is 10000kg, the curb weight is 9805kg, the maximum speed is 89km/h, and the cab seats 3 people.
Chassis Parameters: 6 tires, tire size 10.00R20 18PR, approach angle 23°, departure angle 16°, front overhang 1320mm, rear overhang 1680mm.
Engine Parameters: Equipped with a YCS06245-60 engine, displacement 6234ml, power 180kW, manufactured by Guangxi Yuchai Machinery Co., Ltd.
Specialized Equipment and Applications: The specialized equipment consists of coiled tubing and a roller, used for downhole operations such as sand flushing and well washing in oil and gas wells. It maintains tension on the coiled tubing during operation.
Protective Equipment: The side and rear protective devices are made of Q235 stainless steel and are bolted together. The rear protective device has a cross-sectional dimension of 120mm × 50mm and a ground clearance of 475mm.
Definition: A special-structure specialized work vehicle equipped with coiled tubing rollers, tubing delivery devices, tubing guides, pushers, and a hydraulic power system, used for lowering coiled tubing into the production string of an oil well for operations.
Functional Features: Coiled tubing workover rigs are primarily used for pressurized operations such as well washing, sand flushing, and wax removal in oil and gas wells. They offer advantages such as high efficiency, low cost, and good safety, earning them the nickname "all-purpose workover rig."
Main Components: The rig mainly consists of a chassis, injection head, tubing drum, hydraulic station, control room, and blowout preventer (BOP). The chassis typically uses a high-performance all-wheel-drive chassis. The injection head is the core component, using slips to grip the coiled tubing for lifting or pushing. The tubing drum is used for winding the coiled tubing and is equipped with a constant tension control system. The hydraulic station provides power and meets cooling requirements. The control room allows for centralized control of the operating conditions and observation of the equipment's status. The BOP is a safety device with multiple gate valves.
Product Types: Based on structure, rigs can be divided into composite types (one rig per skid) and those with the drum as a separate skid.
Technological Development: With the advancement of technology, fully electric automated coiled tubing operation equipment has emerged, such as the SLG630D fully electric automated coiled tubing operation equipment developed by PetroChina Machinery. It has overcome technologies such as heavy-duty electric drive injection head and motor direct drive drum, and has achieved "one-button" automatic control and multiple active safety protections.
