Description

Technical Field

[0001] This utility model belongs to the field of drilling tool technology, and in particular relates to a high-temperature resistant hydraulic oscillator. Background Technology

[0002] A drilling hydraulic oscillator is a device used in drilling operations. Its main function is to improve drilling efficiency and reduce drill string wear by generating oscillating force. The drilling hydraulic oscillator utilizes the effect of a throttle, and the hydraulic oil pumped to the drill string generates oscillating force on the drill pipe during the narrowing and expansion of the orifice. Its amplitude and frequency are related to factors such as the size, gap, curvature of the throttle orifice, as well as the viscosity and flow velocity of the liquid.

[0003] Current hydraulic oscillators used in drilling move during operation. As the hydraulic oscillator moves, its outer surface wears against the inner wall of the borehole. This causes wear and tear on the hydraulic oscillator and also raises the overall temperature of the hydraulic oscillator due to friction. Therefore, a high-temperature resistant hydraulic oscillator is provided. Utility Model Content

[0004] The purpose of this invention is to solve the problem of wear and overall temperature rise caused by friction during the movement of current hydraulic oscillators, and to propose a high-temperature resistant hydraulic oscillator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-temperature resistant hydraulic oscillator, comprising a pulse subsection and an oscillation subsection, one end of the oscillation subsection extending into the interior of the pulse subsection and fixedly connected thereto, a protective component being provided on the outer surface of the pulse subsection and the oscillation subsection, and a lubrication component being provided inside the protective component;

[0006] The lubrication assembly includes a connecting rod, a sliding ring fixedly installed at one end of the connecting rod, a connecting spring fixedly installed on the side wall of the sliding ring, a compression ring fixedly installed at one end of the connecting rod, a liquid reservoir fixedly installed on the side wall of the compression ring, and an injection port provided on the outer surface of the liquid reservoir, the injection port extending to the outside of the positioning sleeve.

[0008] A fixing ring is fixedly installed on the side wall of the liquid storage bladder, and an oil storage tube is fixedly installed on the inner wall of the fixing ring. One end of the oil storage tube is connected to the side wall of the liquid storage bladder, and an oil outlet tube is connected to the upper surface of the oil storage tube.

[0009] As a further description of the above technical solution:

[0010] A dustproof mesh plate is fixedly installed at the oil outlet of the oil outlet pipe, and a limit sleeve is fixedly installed on the outer surface of the connecting rod.

[0011] As a further description of the above technical solution:

[0012] Ventilation holes are provided on the side walls of both the sliding ring and the compression ring, and the sliding ring, compression ring and the fixed ring are the same size.

[0013] As a further description of the above technical solution:

[0014] The protective assembly includes a fixed sleeve and a positioning sleeve. The inner surface of the fixed sleeve is fixedly connected to the outer surface of the oscillation sub-section, and the inner surface of the positioning sleeve is fixedly connected to the outer surface of the pulse sub-section. The fixed sleeve has a sliding groove inside, and the positioning sleeve has an installation groove inside.

[0015] As a further description of the above technical solution:

[0016] The outer surface of the sliding ring is slidably connected to the inner wall of the sliding groove, one end of the connecting spring is fixedly connected to the inner side wall of the sliding groove, the outer surface of the squeezing ring is slidably connected to the inner wall of the mounting groove, the outer surface of the fixing ring is fixedly connected to the inner wall of the mounting groove, the liquid storage bladder is located between the squeezing ring and the fixing ring, the oil storage tube is located inside the mounting groove, the limiting sleeve is located outside the positioning sleeve, and the diameter of the limiting sleeve is larger than that of the mounting groove.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by providing a lubrication component, the fixed sleeve, under the support of the moving sliding ring and the connecting spring, drives the connecting rod to move into the mounting groove. At this time, the connecting rod will drive the extrusion ring to extrude the liquid storage bladder. Under the action of the fixed ring, the liquid storage bladder is extruded, and the lubricating fluid inside the liquid storage bladder will flow into the oil storage pipe, and then flow to the outside of the positioning sleeve through the oil outlet pipe. The lubricating oil is squeezed out by the oscillation of the hydraulic oscillator itself, which reflects the utilization rate of resources. At the same time, the lubricating oil can reduce the wear generated during the operation of the hydraulic oscillator and improve the service life of the hydraulic oscillator. On the other hand, the lubricating oil can absorb heat and reduce the heat generated by the friction of the hydraulic oscillator.

[0019] 2. In this utility model, by providing protective components, the hydraulic oscillator moves back and forth inside the pulse section during the working oscillation section. At this time, the hydraulic oscillator moves, and the moving fixed sleeve and positioning sleeve protect the outer surfaces of the oscillation section and the pulse section. When the oscillation section moves, it drives the fixed sleeve to move synchronously, thereby protecting the hydraulic oscillator, reducing the wear on the hydraulic oscillator during drilling, and extending the service life of the hydraulic oscillator.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1-3 This utility model provides a technical solution: a high-temperature resistant hydraulic oscillator, including a pulse section 1 and an oscillation section 2, one end of the oscillation section 2 extending into the interior of the pulse section 1 and fixedly connected, a protective component 3 being provided on the outer surface of the pulse section 1 and the oscillation section 2, and a lubrication component 4 being provided inside the protective component 3;

[0027] The lubrication assembly 4 includes a connecting rod 41, a sliding ring 42 fixedly mounted at one end of the connecting rod 41, a connecting spring 43 fixedly mounted on the side wall of the sliding ring 42, a compression ring 44 fixedly mounted at one end of the connecting rod 41, a liquid reservoir 46 fixedly mounted on the side wall of the compression ring 44, an injection port provided on the outer surface of the liquid reservoir 46 extending to the outside of the positioning sleeve 33, and a fixing ring 47 fixedly mounted on the side wall of the liquid reservoir 46. An oil storage pipe 48 is fixedly installed on the inner wall of the fixed ring 47. One end of the oil storage pipe 48 is connected to the side wall of the liquid storage bladder 46. An oil outlet pipe 49 is connected to the upper surface of the oil storage pipe 48. A dustproof mesh plate is fixedly installed at the oil outlet hole of the oil outlet pipe 49. A limit sleeve 45 is fixedly installed on the outer surface of the connecting rod 41. Ventilation holes are provided on the side walls of the sliding ring 42 and the compression ring 44. The sliding ring 42, the compression ring 44 and the fixed ring 47 are the same size.

[0028] The specific implementation method is as follows: the fixed sleeve 31 drives the connecting rod 41 to move into the mounting groove 34 under the support of the moving sliding ring 42 and the connecting spring 43. At this time, the connecting rod 41 will drive the compression ring 44 to compress the reservoir 46. Under the action of the fixed ring 47, the reservoir 46 is compressed. At this time, the lubricant inside the reservoir 46 will flow into the oil storage pipe 48, and then flow to the outside of the positioning sleeve 33 through the oil outlet pipe 49. When the connecting rod 41 moves, it will also drive the limiting sleeve 45 to move synchronously. When the limiting sleeve 45 contacts the side wall of the positioning sleeve 33, the connecting rod 41 cannot move. At this time, when the fixed sleeve 31 continues to move, the connecting spring 43 is compressed.

[0029] The protective component 3 includes a fixed sleeve 31 and a positioning sleeve 33. The inner surface of the fixed sleeve 31 is fixedly connected to the outer surface of the oscillation sub 2, and the inner surface of the positioning sleeve 33 is fixedly connected to the outer surface of the pulse sub 1. The fixed sleeve 31 has a sliding groove 32 inside, and the positioning sleeve 33 has an installation groove 34 inside. The outer surface of the sliding ring 42 is slidably connected to the inner wall of the sliding groove 32. One end of the connecting spring 43 is fixedly connected to the inner side wall of the sliding groove 32. The outer surface of the compression ring 44 is slidably connected to the inner wall of the installation groove 34. The outer surface of the fixed ring 47 is fixedly connected to the inner wall of the installation groove 34. The liquid reservoir 46 is located between the compression ring 44 and the fixed ring 47. The oil reservoir 48 is located inside the installation groove 34. The limiting sleeve 45 is located outside the positioning sleeve 33, and the diameter of the limiting sleeve 45 is larger than that of the installation groove 34.

[0030] The specific implementation method is as follows: the hydraulic oscillator moves back and forth inside the pulse section 1 during the working oscillation section 2. At this time, the hydraulic oscillator moves, and the moving fixed sleeve 31 and the positioning sleeve 33 protect the outer surfaces of the oscillation section 2 and the pulse section 1. When the oscillation section 2 moves, it will drive the fixed sleeve 31 to move synchronously.

[0031] Working principle: The hydraulic oscillator moves back and forth inside the pulse section 1 during operation. This movement of the hydraulic oscillator, along with the movement of the fixed sleeve 31 and positioning sleeve 33, protects the outer surfaces of the oscillating section 2 and pulse section 1. As the oscillating section 2 moves, it drives the fixed sleeve 31 to move synchronously. Supported by the connecting spring 43, the fixed sleeve 31, through the moving sliding ring 42, moves the connecting rod 41 into the mounting groove 34. This causes the connecting rod 41 to squeeze the compression ring 44 against the reservoir 46. Under the action of the fixed ring 47, the reservoir 46 is squeezed, causing the lubricant inside to flow into the oil storage pipe 48 and then through the oil outlet pipe 49 to the outside of the positioning sleeve 33. As the connecting rod 41 moves, it also drives the limiting sleeve 45 to move synchronously. When the limiting sleeve 45 contacts the side wall of the positioning sleeve 33, the connecting rod 41 cannot move. When the fixed sleeve 31 continues to move, the connecting spring 43 is compressed.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
