Description
Technical field automatic vertical drilling tool hydraulic control device belongs to the auxiliary equipment of subsurface boring device, particularly relates to hydraulic drive controlling organization in the drilling tool.
The principle of the anti-oblique well straightening of background technology closed loop drilling tool is that the flash at drilling tool applies an opposite lateral force when bore inclining, promotes drilling tool and creeps into to the direction of drop angle.If adopt the known technology flow control methods, carry out the restoring force that piston can only produce limited direction, it is opposite with inclination drilling tool flash to produce a direction in any direction, and its size can be according to the adjustment power of the mechanical property on stratum; In addition, in known technology, adopt mud to transmit medium, cause wearing and tearing hydraulic valve as fluid pressure; If when adopting single loop output, make three execution pistons obtain different pressure, use parts more, the cost height, reliability is low.For addressing the above problem, designed this hydraulic control device.
Summary of the invention can both to be measured the tilting value of drilling tool and provide corresponding well straightening signal any direction in order to make in drilling process, make drilling tool in the deviant scope that allows, finish probing, hydraulic control device is an important step in the automatic vertical drilling tool, and the purpose of this utility model provides a kind of making it and all can be corrected in the inclination of boring any direction also; Adopt the hydraulic circuit of independent sealing, in oil circuit, inject the automatic vertical drilling tool hydraulic control device of senior cleaning hydraulic oil as pressure transmission medium.It has solved the function of the measurement well straightening of any direction; Device is not vulnerable to pollute, long working life; Stability and safety is reliable; Technical problem such as simple in structure, easy to maintenance.
For this reason, the utility model has adopted following technical scheme:
--the hydraulic control device that this device is made up of pluger type hydraulic pump (3), electromagnetic pressure proportioning valve (6), execution piston (8) and accumulator (10) is installed in the ring-shaped cavity of the automatic vertical drilling tool that is made of interior pipe (1) and outer tube (2); Pluger type hydraulic pump is communicated with electromagnetic pressure proportioning valve, execution piston, accumulator respectively by oil circuit; The interior pipe of drilling tool, the upper and lower part of outer tube link to each other with drilling rod or drill collar, drill bit respectively; The electromagnetic pressure proportioning valve links to each other with electronic-controlled installation.
--pluger type hydraulic pump is fixed on the outer tube by shell, drives revolution by drilling rod or drill collar.
--carry out piston and contact with gripper shoe; Transmission coupling through power causes outer tube to touch mutually with the hole wall of boring.
--injecting cleaning hydraulic oil in hydraulic control device is pressure transmission medium.
--in the outside of carrying out piston gripper shoe (7) is housed, its top is equipped with pivot pin (11), and gripper shoe can be rotated around pivot pin; Be provided with back-moving spring (9) in the bottom of gripper shoe.
Facts have proved: compared with prior art, the utlity model has following beneficial effect:
(1) to the tilting value of any direction in drilling process, all can measure, and give well straightening, having overcome prior art only can be in the shortcoming of limited direction well straightening.
(2) be the hydraulic circuit of medium owing to what adopted independent sealing with cleaning hydraulic oil, overcome and adopted mud to transmit medium in the known technology, cause defective, improved the reliability and the working life of this device the wearing and tearing of hydraulic valve as hydraulic coupling.
(3) simple in structure, easy to maintenance.

Specific embodiment Fig. 1 Fig. 2 and Fig. 3 are and implement a kind of optimal way of the present utility model, referring now to them technical scheme are remake further and describe.Each label is defined as follows among the figure:
Pipe is round tube in the 1-, constitutes the axle of automatic vertical drilling tool, and its top links to each other with drilling rod, and the bottom links to each other with drill bit, and generator amature is fixed on its outer wall.The 2-outer tube is the selected equipment of common drilling tool, and outside the pipe, both coincide in the axle center in being contained in, and it and interior pipe constitute the agent structure of automatic vertical drilling tool.Between the inner and outer pipe annular housing, generator, measurement, control and actuating unit are installed within it.The 3-pluger type hydraulic pump is a universal standard part, it and execution piston, and electromagnetic pressure proportioning valves etc. link to each other, and also can select other high-pressure pump for use.The 4-plunger.5-plunger displacement pump shell is between plunger and outer tube.6-electromagnetic pressure proportioning valve.The 7-gripper shoe is installed in the outside of carrying out piston, and its top is equipped with pivot pin, and gripper shoe can rotate around it, and is provided with back-moving spring in its underpart.8-carries out piston, and it contacts with gripper shoe, and the transmission coupling through power causes gripper shoe to be touched mutually with the hole wall of boring.The 9-back-moving spring, the normal condition of adjustment gripper shoe.The 10-accumulator is connected with pluger type hydraulic pump, execution piston, electromagnetic pressure proportioning valve etc. through oil circuit.The 11-pivot pin.The 12-oil cylinder is communicated with pluger type hydraulic pump, electromagnetic pressure proportioning valve through oil circuit.The tie point of M-electromagnetic pressure proportioning valve and electronic-controlled installation.8-1,8-2,8-3 are for carrying out piston geometric position schematic diagram.F1, F2 are for acting on the power of carrying out on the piston (8) respectively.
The operating principle of this device:
When drilling rod rotates, drive plunger displacement pump and rotate, produce hydraulic oil, high pressure oil content three tunnel is transported to three by three solenoid-operated proportional pressure valve and carries out piston.When unlike signal voltage is applied on three solenoid-operated proportional pressure valve, then carries out on the piston and obtain three different pressure at three.If when recording the direction of flash that bore inclining and drilling tool tilt such as Fig. 4 arrow indication, then give to be connected in the solenoid-operated proportional pressure valve of carrying out piston (8-1) and to apply signal voltage, make it produce the pressure of size as F1; In like manner make and carry out the pressure of piston (8-2) generation shown in figure F2; And do not exert pressure to carrying out piston (8-3); The high edge direction of making a concerted effort to point to of F1 and F2 then.When carrying out piston (8-1) and (8-2) promote with gripper shoe that it touches mutually respectively, gripper shoe is supported in borehole wall, and under the promotion of reaction force, drilling tool is pushed to the direction opposite with arrow among Fig. 4, promptly carries out drop angle and creeps into.Boring is advanced along vertical direction.
