The main characteristics of drilling rig

(1) the ZJ40DBS rig for the electromechanical integration design, drilling machinecan realize the digital control, has the function of automatic drilling. And with strong within the system and outside the system communication ability. At the same time the rig is equipped with hydraulic moving device can meet therequirement of the cluster type well. In view of 4000m in deep well drilling cycle is short, frequent moving specific requirements, low cost of operations, ZJ40DBS drilling rig in the design takes full use of economic, technological design.

(2) drilling rig driving mode is AC - VFD - AC drive mode. The alternating current power generation unit output by frequency converter, and then drive the AC frequency conversion motor, drive winch, rotary table and two mud pumps. Theoil rig electric drive system using AC variable frequency speed control system and AC frequency conversion motor, motor and electric control system technology is mature, high reliability.

(3) the winch and a turntable driven by the unification of 1 970kW AC variable frequency motor. JC40DB winch is stepless speed regulation, has the advantages of light weight, small volume, small amount of maintenance. Winch speed and control the energy consumption braking and AC frequency conversion control, under normal circumstances, hydraulic disc brakes only parking,positioning and emergency stop function, but also has a manual control loweringfunction. Winch all operating parameters, including the drilling speed, hook position, various security settings, CNC frequency automatic drill bit feeding,energy consumption braking function, through the computer and the electronic control system to realize full digital control.

(4) the use of open front derricks derricks, effective height 43M; the base for thespiral type, the floor surface with high 7.5m. Drilling derrick, the base body is in an integrated lifting structure. Winch power to lift derrick, the lifting derrick, the vertical root box and lifting derrick together. The derrick vertical root box in place,using a winch, winch and the background will be lifting in place, to complete the whole process of lifting.

(5) with integrated driller operation room, operation, control, drilling instruments and recording com., driller in the driller operation indoor sitting operation with air conditioner, improved the working conditions, and more safety. The rig is equipped with integrated control system, combined with the control module,monitor the drilling operation, drilling parameters can be set, the main equipment of drilling condition monitoring function, record storage and possesses the function of drilling parameters.

(6) drilling machine can be equipped with step type hydraulic moving device, in the same field linear cluster type well.
