Abstract
The utility model relates to a top drive drilling device with an integrated hydraulic system. A hydraulic system in a top drive comprises an integrated oil tank (1), wherein the integrated oil tank (1) is arranged on the integral top drive, the oil tank is connected with a pressure compensating type variable hydraulic pump (2) and a control valve assembly (3) through a hydraulic pipeline (5), the pressure compensating type variable hydraulic pump is driven by a motor (4), a hydraulic oil return pipeline returns to the oil tank through a heater (6) and a cooler (7) to raise temperature or lower temperature, and a main control valve assembly is an electromagnetic valve-controlled plugging type integrated valve assembly, and is used for controlling hoisting ring tilt (8), rotation (9), main motor brake (10), back-up tongs (11), a balance system (12), a remote control inner spraying-prevention device (13) and the like in the top drive. The whole hydraulic system adopts a PLC (programmable logic control) system, so the procedure control of each function is realized.
Description
Technical field
The utility model belongs to the improvement of oil-well drilling equipment technical field, particularly top-drive drilling.
Background technology
The top driving well drilling device structure of routine ground hydraulic power source system is substantially: the dynamical system that drive on the top comprises power system and hydraulic system.Hydraulic system comprises hydraulic power source, control valve group, hydraulic pressure manifold.Hydraulic power source is settled on the ground, comprise fuel tank, pump group, connect manifold, electric control box, gate valve etc., the delivery hydraulic pressure pipeline group of the fluid that pumps by driving from ground to the top driven to the top, and the control valve group is controlled by each function executing unit part of solenoid control.
Following shortcoming has been driven on the top that existing ground hydraulic source is controlled: 1, need powerful motor and pump group to drive, power consumption is larger; 2, the top is driven at derrick up and downly, and the distance of driving from ground to the top needs 100 meters at least, and is very large to the pressure loss of hydraulic oil, needs increased pressure, also high for the requirement of withstand voltage of system, and hydraulic line need to use and pull out soon joint usually, is easy to damage; 3, long installing/dismounting apart from hydraulic line has increased labour intensity; 4, hydraulic line takies on-the-spot more space, and the work at scene is had certain obstruction; 5, the control valve group adopts the solenoid control Sandwich plate valve, and volume is large, because tolerance is relatively poor during the vibrations that the Sandwich plate valve self reason is driven for the top, easily damages.
The utility model content
The utility model purpose is a kind of top-drive drilling with integrated hydraulic system of design, the drawback of bringing on ground to overcome existing top drive drilling hydraulic system.
Specifically, top-drive drilling with integrated hydraulic system, have TDS, hydraulic system and electric control system, it is characterized in that hydraulic system becomes one and drive body junction with the top of TDS being combined and being positioned at the drilling rig top.
Hydraulic system during drive on described top is included in pushes up the integrated fuel tank that drives on the main body, and fuel tank is connected by hydraulic line with pressure compensation type volume adjustable hydraulic pump and control valve group, and hydraulic pump is by a motor-driven; Heater and cooler are housed on the hydraulic oil-returning pipeline; The main control valve group is that solenoid control plug-in pile-up valve group and the suspension ring inclination that the top is driven, revolution, main motor brake, back-up tong, balance sysmte, remote control inner blowout preventer are controlled; Whole hydraulic system adopts the PLC programmable control system to realize the programme-control of all functions.
The top that the utility model integrated hydraulic system controls is driven and had the following advantages: 1, compact conformation is driven on this top, and volume is little; 2, the hydraulic system modular construction that adopts distributes rationally, use power of motor less, but adopt both drive hydraulic system principles of independent pressure compensation type variable pump, variable pump is the less discharge capacity of output when working clearance at ordinary times, it is the compensation that determines pressure for load, therefore save energy consumption, increased application life; 3, all hydraulic pipeline all drives body interior, the back side and side on the top, does not affect working space, and the pressure of hydraulic oil is less, and fed distance is near, is convenient to regulate and change; 4, the installation that is combined as a whole is driven on whole hydraulic system and top, need not to increase fixing link; 5, the control valve group adopts the cartridge valve group of solenoid control, and volume is little, because cartridge valve all installs on the valve body with integral body, seal very reliably, and the cartridge valve of employing also has anti-little stifled self-cleaning function, so long service life, easily replacing.

The specific embodiment
Provided the utility model specific embodiment such as figure, all functions parts (6 ~ 13) all use pipeline (5) to connect among Fig. 1.Top-drive drilling with integrated hydraulic system has TDS, hydraulic system and electric control system, and its hydraulic system becomes one and drives body junction with the top of TDS and is combined and is positioned at the drilling rig top.
The top integrated hydraulic system of driving fully and the top drive body junction and be combined, comprise the compositions such as hydraulic oil container 1, hydraulic pump 2, motor 4, integrated control valve group 3 and hydraulic pressure manifold 5.Each functional part suspension ring that drive on the top tilt 8, the controlling of revolution 9, main motor brake 10, back-up tong 11, balance sysmte 12, remote control inner blowout preventer 13, operation by the integrated hydraulic system is finished, the fill order of hydraulic system is sent on the hydraulic system of driving on the top by a holding wire by the programmable logic controller in the power system, and the operating personnel that driven by the top finish in the driller station straighforward operation.
TDS in the utility model, electric control system are the prior art universal architecture, no longer describe its concrete structure here.
