Description

Technical Field

[0001] The invention relates to the technical field of resource exploration equipment, in particular to a rotary guided high temperature resistant shock absorbing tool. Background Art

[0002] Rotary steerable drilling technology is widely used in oil and gas exploration, especially in high temperature and high pressure environments. In order to ensure the efficient and stable operation of rotary steerable drill bits under these extreme conditions, high-temperature resistant vibration damping tools are indispensable. These tools can reduce vibration during drilling, protect drilling equipment and improve drilling efficiency.

[0003] When using the existing rotary guided high temperature resistant shock absorbing tool, it is necessary to use a tool to install the rotary guided high temperature resistant shock absorbing tool between the drill rod and the drill bit. The rotary guided high temperature resistant shock absorbing tool can rotate synchronously with the drill bit and buffer the vibration and impact force generated by the drill bit. The installed rotary guided high temperature resistant shock absorbing tool is exposed inside the borehole, which easily causes a large amount of gravel and mud generated by the borehole to enter the protective cover of the rotary guided high temperature resistant shock absorbing tool, which not only easily causes friction damage to the outer surface of the rotary guided high temperature resistant shock absorbing tool, but also affects the buffering and shock absorbing effect of the rotary guided high temperature resistant shock absorbing tool, thereby reducing the service life of the rotary guided high temperature resistant shock absorbing tool.

By arranging the pressure-resistant ring 13 between the connecting bolt 19 and the connecting plate 18, it is convenient to increase the force area applied to the connecting plate 18 by the connecting bolt 19 when the connecting plate 18 is installed using the connecting bolt 19, thereby improving the connection stability of the connecting bolt 19.

[0036] The cleaning blocking mechanism 2 includes a rotating cleaning unit 21 . The rotating cleaning unit 21 is located outside the damping tool body 17 . The rotating cleaning unit 21 is used to clean the outer surface of the damping tool body 17 .

[0037] As a further limitation of the cleaning blocking mechanism 2 of the present invention, the rotating cleaning unit 21 includes a mounting ring 2101, the inner wall of the mounting ring 2101 is fixedly connected to the outer surface of the shock absorbing tool body 17, the internal rotating connection of the mounting ring 2101 is provided with rolling balls 2103 arranged at equal distances in a circumferential direction, the outer surface of the mounting ring 2101 is provided with a cleaning sleeve 2106, and the inner wall of the cleaning sleeve 2106 is provided with spiral grooves 2108 arranged at equal distances in a circumferential direction, and a plurality of rolling balls 2103 are respectively slidably connected to the mounting ring 2101.

The sliding retaining ring 2205 can block the installation operation groove 2203, thereby reducing the amount of mud and gravel that enter the outer surface of the shock-absorbing tool through the outer protective cover of the shock-absorbing tool, thereby improving the protection performance of the high-temperature resistant shock-absorbing tool and further increasing the service life of the high-temperature resistant shock-absorbing tool.

By fixing the stabilizing snap rings 2210 on the outer surface of the telescopic springs 2209, the telescopic direction of the telescopic springs 2209 can be limited, thereby improving the telescopic stability of the telescopic springs 2209.

[0045] The specific implementation of this embodiment is as follows: when the first cleaning brush 2110 that rotates and moves is used to clean the portion of the outer surface of the shock absorbing tool body 17 that contacts the mud and gravel, the upper sliding sleeve 2201 and the lower sliding sleeve 2202 fixed between the two connecting plates 18 can be moved up and down, and by making the sliding cylinder 2213 fixed on the bottom surface of the upper sliding sleeve 2201 slide in the telescopic sliding groove 2214 opened on the lower sliding sleeve 2202, a protective cover can be formed between the upper sliding sleeve 2201, the lower sliding sleeve 2202 and the sliding cylinder 2213 to prevent the upper sliding sleeve 2201 from sliding and the lower sliding sleeve 2202 from sliding.
