Abstract
The invention relates to a downhole tool thrust actuating mechanism for automatically and vertically drilling used in the field of oil and natural gas exploration and development and mainly consists of a nozzle, a piston, a cylinder sleeve, a palm, a piston ring and a pin roll; the profile of the cylinder sleeve of the thrust actuating mechanism is rectangle; a round through hole is arranged inside the thrust actuating mechanism; one side of the thrust actuating mechanism is provided with a pin roll hole and a trapezium slot; the lower part of the thrust actuating mechanism is provided with aseal ring slot; a seal ring is arranged in the seal ring slot; the piston is arranged in the round through hole of the cylinder sleeve; the outer circle of the piston is provided with the annular slot of the piston; the piston ring is arranged on the annular slot of the piston; the nozzle is arranged in the inner hole of the piston and fixed by an elastic check ring; the palm and the cylinder sleeve are connected by the pin roll; a drilling liquid generates a hydraulic pressure difference when flowing into the annular space of a borehole through the nozzle; the piston extends to the outside under the effect of the pressure difference; simultaneously the palm is driven by the pressure difference to outwards push the well to generate a streighting force. The downhole tool thrust actuating mechanism is arranged at the side surface of the body of a downhole tool offset mechanism for automatically and vertically drilling and matched with a control system for use and capable of generating astraightening force of a certain direction.
Description
Technical field
The present invention relates to a kind of automatic vertical drilling downhole tool thrust executing agency that is used for oil, natural gas exploration and development field.
Background technology
At present the straight well boring method in oil, natural gas exploration and development field is: in drilling process, come the control well oblique angle in keeping certain scope through manual work adjustment drilling parameter through deviational survey instrument measuring well again after tiltedly.This method control accuracy is lower, and can't realize real-time corresponding control, complicated operating process, and construction cost is high, has higher construction risk.
Summary of the invention
The automatic vertical drilling downhole tool can be through the control system that carries; Hole angle in the control drilling process remains in certain scope automatically, and has the function to the inclined shaft well straightening, and whole control process need not manual intervention; Can increase work efficiency, reduce risk, cost.The automatic vertical drilling downhole tool mainly is made up of control system and executing agency.The control system of automatic vertical drilling downhole tool is through controlling the generation that the thrust executing agency of installing in the executing agency realizes restoring force, to reach the purpose at well straightening and control well oblique angle.The objective of the invention is to provide a kind of thrust execution device of fluid power driving for the automatic vertical drilling downhole tool.
The technical solution adopted for the present invention to solve the technical problems is: a kind of thrust execution device of automatic vertical drilling, be installed in the side of automatic vertical drilling system actuator body, and comprise nozzle, piston, cylinder sleeve, palm, bearing pin; An appearance profile is the cylinder sleeve of rectangle, and manhole is arranged in the cylinder sleeve, and a side has pin shaft hole and dovetail groove; The outside, bottom has seal groove, cylinder sleeve to be installed in the side of actuator body, and sealing ring is contained in the seal groove of cylinder sleeve; Piston is installed in the manhole of cylinder sleeve; Outside piston has piston ring groove, and piston ring is housed on the piston ring groove, and piston inner hole is equipped with nozzle; Nozzle is fixed by circlip, is connected through bearing pin after the dovetail groove of palm and cylinder sleeve matches.The end that piston contacts with palm is the piston spherical crown, and three piston runners that are symmetrically distributed along circumference communicate with the endoporus that nozzle is installed.The appearance profile of palm is a rectangle, and the outer is an arc profile, and a side has rectangular aperture groove and circular palm pin shaft hole.
Advantage of the present invention is: simple in structure, reliable, response is fast; Can action rapidly under the driving of seldom drilling fluid; Can produce enough big thrust, piston seal is reliable, for the generation of automatic vertical drilling downhole tool restoring force provides good executing agency with accurately controlling.
