Description
Technical field
The utility model 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: come the control well oblique angle in keeping certain scope by artificial adjustment drilling parameter by deviational survey instrument measuring well again after tiltedly in drilling process.This method control accuracy is lower, and can't realize real-time corresponding control, complicated operating process, and there is higher construction risk in the construction cost height.
Summary of the invention
The automatic vertical drilling downhole tool can be by 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 by 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 purpose of this utility model is the thrust executing agency that provides a kind of fluid power to drive for the automatic vertical drilling downhole tool.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of thrust execution device of automatic vertical drilling, be installed in the side of automatic vertical drilling system actuator body, comprise nozzle, piston, cylinder sleeve, palm, bearing pin, an appearance profile is the cylinder sleeve of rectangle, manhole is arranged in the cylinder sleeve, one side has pin shaft hole and dovetail groove, there is seal groove in the outside, bottom, cylinder sleeve is installed in the side of actuator body, 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 by 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.
The utility model has the advantages that: 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.
