Product Description Oil rig drilling rig equipment ZJ50DBS Oil drilling rig and spare partsA workover rig is a specialized drilling rig used in the oil and gas industry for performing workover operations on existing wells. Workover operations refer to a range of maintenance, repair, and remedial activities conducted to optimize or restore the productivity of a well.Workover rigs are designed to handle various tasks, including:- Well intervention. Workover rigs are used to access the wellbore for interventions such as removing debris or scale, cleaning out sand or other obstructions, or repairing damaged or malfunctioning downhole equipment.- Completion changes. Workover rigs are employed to make changes or modifications to the well completion, which involves altering the configuration of the casing, tubing, and production equipment. This allows for adjustments to production zones, installation of new equipment, or optimizing the flow of fluids.- Stimulation and enhancement. Workover rigs are utilized to stimulate the production of hydrocarbons by performing operations such as acidizing, fracturing, or re-perforating the reservoir. These techniques help increase the permeability of the formation and improve the flow of oil or gas into the wellbore.- Plugging and abandonment. Workover rigs are involved in plugging and abandoning wells that have reached the end of their productive life or are no longer economically viable. This process requires the proper sealing and isolation of the well to prevent any potential environmental or safety risks.Workover rigs are typically smaller and more mobile compared to drilling rigs. They can be truck-mounted, skid-mounted, or trailer-mounted, allowing for easier transportation between well locations. Workover crews, consisting of skilled operators and technicians, operate these rigs and perform the necessary tasks under the supervision of a wellsite supervisor.Workover operations are conducted to maintain or enhance the productivity of existing wells, extend their lifespan, and maximize recovery from reservoirs. They play a vital role in the overall lifecycle management of oil and gas wells, ensuring optimal production and efficiency while minimizing downtime and costly interventions.Product description of ZJ50DBS Oil drilling rig and spare parts 1) Adopting digital-control technique, computer technique and integrating mechanics, electricity, hydraulics and pneumatics into design, the intelligent control for drilling rig is realized through PLC technology and touch screen.2) Adopting AC VF motor drive, the drawworks , rotary table and mud pump achieves stepless speed regulating function .3)The drawworks is a structure with single shaft, gear transmission, stepless speed regulating, the brake adopts hydraulic disk brake and dynamic brake together, with simple structure and reliable performance.4)Adopting constant WOB auto-bit-feed device, the WOB is controlled precisely.5)The rig operation has realized the functions for collecting, display, storing, printing and transfer of drilling parameters, and the function of multi-points monitoring and communication.6)The rig operation has realized the full digital-control or digital closed-loop control for traveling block position, trip speed,safety presetting and interlock protection, and preventing collide up and impact down (crown and RT protection) .7)with the online monitoring system for working s tatus of mechanical, electric, hydraulic and pneumatic implements, failure alarm and failure self-diagnosis has been realized, the equipments can work normally and troubleshooting can be done easily.8)The driller control cabin is independent and lifted hydraulically (ZJ70DBS), without contacting the drill floor, with littlevibration, and convenient for installation and teardown. The driller control cabin is a pressurized unit for explosion proof(certificated). The drillers can fitful all drilling operation parameter setting on the operating chair, the operation manner hasbeen improved and the labor intensity lightened greatly ...9)It can be equipped with rig moving device, satisfying the requirement for cluster well drilling.10)Satisfying the requirement for TDS installation.Welcome to consult, we will provide the most comprehensive technical support!
