(1) ZJ40DBS rig as mechatronics design, rig123.net' target='_blank'>drilling rig can achieve digital control, with automatic drilling function. And it has a strong ability to communicate within the system and outside the system. Meanwhile rig equipped with hydraulic translation means to meet the requirements of cluster well played. For 4000m deep well drilling cycle is short, safe move frequently, specific requirements for low-cost operation, ZJ40DBS rig used in the design of the full economic, technical optimization.

(2) drilling rig driven approach to AC-VFD - AC drive. Generators output AC power by the inverter treatment and then drive AC variable frequency motor, separately driven winch, rotary table and two mud pumps. Electricity transmission system using oil rig use AC variable speed control system and AC variable speed motors, electrical and electronic control system technology is mature, high reliability.

 

(3) 1 station by the winches and rotary 970kW AC inverter motor unified driver. JC40DB winch as variable speed, light weight, small size, less maintenance and so on. Winch speed and dynamic braking function is controlled by AC variable frequency control and, under normal circumstances, only the hydraulic disc brake from parking, location and emergency shutdown role, but also has a manual control function delegated drill. Winch all operating parameters, including tripping speed, hook position, various security settings, CNC automatic drilling inverter, dynamic braking and other functions, both through computer and electrical control systems to achieve a full digital control.

 

(4) before opening derrick derrick use, effective height 43m; the base for the jack-screw, drill floor high 7.5m. Derrick, base body as one of the lifting structure. Power winch to hoist the mast when lifting derrick, rooted cartridge together with the lifting derrick. Derrick box to be rooted in place, use a winch power, will rise from the position winch and back, complete the lifting process.

 

(5) has integrated driller operating room, operating, electronically controlled, integrated drilling instrumentation and recording, the driller can drill operator sitting indoors with air conditioning operation in the Division improved driller working conditions, while more Safety. Rig with integrated control system, combined with the control module, can driller drilling operations, monitoring drilling parameters set, the rig main equipment condition monitoring and other functions, and has a record storage of drilling parameters.

 

(6) hydraulic drilling rig can be equipped with a stepping translation device that can play the same cluster wells in well field line.
