Description

Technical Field

[0001] The utility model relates to the field of drilling, in particular to a high-efficiency hydraulic oscillator. Background Art

[0002] A hydraulic oscillator is a commonly used tool in the drilling industry. It is mainly used to generate mechanical vibrations during the drilling process to reduce friction between the drill pipe and the well wall and prevent the occurrence of drill sticking. It can also improve drilling efficiency and safety. It uses fluid dynamics effects and a specially designed internal structure to create pressure pulsations in the drilling fluid flowing through it, which are then converted into mechanical vibrations. This vibration can be transmitted along the drill pipe, helping to break rocks and improve the efficiency of carrying drill cuttings.

[0003] When using the existing hydraulic oscillator, it is first necessary to install the hydraulic oscillator at the lower part of the drill string, close to the drill bit, and then use the specially designed internal structure to make the drilling fluid flowing through it generate pressure pulsation, which is then converted into mechanical vibration and transmitted along the drill pipe to achieve the purpose of breaking rocks and improving the efficiency of carrying drill cuttings. However, the existing hydraulic oscillator is usually exposed to the outside, so the outside is easily subject to greater wear and tear, which shortens the service life.

[0004] In summary, there is an urgent need for a high-efficiency hydraulic oscillator with a protective function to solve the above problems. Utility Model Content

[0005] In order to overcome the disadvantage of the existing hydraulic oscillator being exposed to the outside and easily damaged, the utility model aims to provide a high-efficiency hydraulic oscillator with a protective function.

[0006] Technical solution:

[0007] A high-efficiency hydraulic oscillator comprises a hydraulic oscillator, a drill bit connection ring, a drill column connection ring and a first protective sleeve. The right side of the hydraulic oscillator is connected to the drill bit connection ring, the left side of the hydraulic oscillator is connected to the drill column connection ring, and the outer wall of the hydraulic oscillator is connected to the first protective sleeve.

[0008] In one of the embodiments, it also includes a second protective sleeve, a fixing ring, an elastic member and a limit block. The second protective sleeve is covered on the outer wall of the first protective sleeve. The front and rear sides of the hydraulic oscillator are connected to the fixing ring. The opposite sides of the fixing ring are connected to the elastic members. The ends of two adjacent elastic members that are away from each other are connected to the limit blocks. The elastic member and the limit block both pass through the first protective sleeve and the second protective sleeve and clamp the second protective sleeve.

[0009] In one of the embodiments, a third protective sleeve and a threaded sleeve are also included. The threaded sleeves are threadedly arranged on both sides of the second protective sleeve. The third protective sleeve is connected to the sides of the two threaded sleeves away from each other. The third protective sleeve blocks the drill bit connecting ring and the drill column connecting ring respectively.

[0010] In one embodiment, a rubber sleeve and a sponge sleeve are further included. The left and right sides of the first protective sleeve are connected to the rubber sleeves, and the sides of the two rubber sleeves that are away from each other are connected to the sponge sleeves.

[0011] In one embodiment, the first protective sleeve completely covers the outer wall of the hydraulic oscillator.

[0012] In one embodiment, the outer end of the third protective sleeve is longer than the drill bit ring and the drill string ring.

[0013] The utility model has the following advantages:

[0014] 1. The first protective cover of the utility model can protect the outside of the hydraulic oscillator, prevent the hydraulic oscillator from being damaged during use, and increase the service life of the hydraulic oscillator.

[0015] 2. The second protective cover of the utility model can further protect the outside of the hydraulic oscillator and enhance the protective effect.

[0016] 3. The third protective sleeve of the utility model can protect the drill bit connecting ring and the drill column connecting ring at both ends. BRIEF DESCRIPTION OF THE DRAWINGS

When the second protective sleeve 5 needs to be replaced, the limit block 8 can be pressed inward first, and the elastic member 7 can be compressed so that the limit block 8 releases the second protective sleeve 5. At this time, people can pull the second protective sleeve 5 outward to remove it, and then put the new second protective sleeve 5 on the first protective sleeve 4, and then release the limit block 8. The elastic member 7 returns to its original state, driving the limit block 8 to move outward and reset, so that it can re-jaw the second protective sleeve 5. After the device is used up, the device can be removed.
