Embodiment 1

[0046] Such as Figure 1 to Figure 3 The casing slip matching device shown includes a box body 1 and an annular groove 2 opened on the top surface of the box body 1. The side of the annular groove 2 has a first gap 3 communicating with the outside of the box body 1. The top of the first notch 3 is open, and also includes a lifting platform 4 located inside the box body 1, a driving device 5 for driving the lifting platform 4 up and down, and a rotating shaft 6 that is rotatably matched with the lifting platform 4. The rotating shaft 6 protrudes from the top of the annular groove 2 to the outside of the box body 1, and also includes several circular hooks 7 uniformly distributed on the outer wall of the rotating shaft 6 in the same direction of rotation, and the hooks 7 are located outside the box body 1; it also includes a detachable connection The handle 8 at the top of the rotating shaft 6. A square hole 10 is provided at the top of the rotating shaft 6, and a square insert...

Embodiment 2

[0060] A casing slip supporting device, on the basis of Embodiment 1, also includes a sheath 12 for placing in the annular groove 2, such as Figure 4 and Figure 5 As shown, the shape of the sheath 12 matches the groove type of the annular groove 2; the top surface of the sheath 12 is open and the bottom surface is closed, and the bottom surface of the sheath 12 is provided with an anti-collision hole 13, and the anti-collision hole 13 is used to avoid the The sleeve 12 interferes with the rotating shaft 6 and the crotch 7 when entering and leaving the annular groove 2 .

[0061] The sheath 12 is annular, and the outer diameter of the sheath 12 is equal to the inner diameter of the annular groove 2 , and the side wall of the sheath 12 is provided with a second notch 14 equal in width to the first notch 3 .

[0062] The inner wall of the annular groove 2 is provided with a plurality of longitudinally distributed limiting grooves 15, the top of the limiting grooves 15 is conne...

Embodiment 3

[0069] A casing slip supporting device, on the basis of any of the above-mentioned embodiments, such as Figure 8 As shown, the bottom end of the rotating shaft 6 is rotatably connected to the bottom of the annular groove 2, the outer wall of the rotating shaft 6 is movably sleeved with a sliding sleeve 17, and a through hole is opened on the lifting table 4, and the sliding sleeve 17 is fixedly connected to the through hole. On the inner wall of the hole, the rotating shaft 6 and the lifting platform 4 realize rotational cooperation through a sliding sleeve 17 .

[0070] The driving device 5 in this embodiment cannot interfere with the rotating shaft 6, as Figure 8 As shown, the driving device 5 is composed of several circularly distributed elevators, and all the elevators need to be linked synchronously.

[0071] It should be noted that the attached Figure 8 The cross-section passes through the first gap 3 .

Abstract

The invention discloses a casing slip matching device and a using method thereof, which comprises a box body and an annular groove set on the top surface of the box body. It also includes a lifting platform located inside the box, a driving device for driving the lifting platform to go up and down, and a rotating shaft that is rotatably matched with the lifting platform. The rotating shaft extends from the top of the annular groove to the outside of the box. A plurality of hooks with the same rotation direction on the outer wall of the rotating shaft are located outside the box; a handle detachably connected to the top of the rotating shaft is also included. The purpose of the present invention is to provide a casing slip matching device and its use method to solve the problem that the casing slips in the prior art are easy to fall on the drill floor and hurt or trip the drill floor workers, and it is not conducive to the subsequent Take and use issues, realize stable and convenient bundling of casing slips, avoid interference with drilling floor operations, and facilitate the transfer or storage of casing slips.

Description

technical field [0001] The invention relates to the field of petroleum casing, in particular to a matching device for casing slips and a method for using the same. Background technique [0002] Casing operation is an important process for stabilizing the wellbore in the process of oil and gas drilling. A wellbore passage separated from the formation. Casing slips are tools used to hold and suspend casing strings at the wellhead during casing running. Different from the three-lobed drill slips, the casing slips are a multi-piece structure connected by hinge pins, and due to the large size span of the casing, the matching casing slips also have different sizes . In the prior art, it is necessary to carry a large number of casing slips of different sizes for backup no matter in the process of well team transfer or in the process of on-site drilling approval. The packaging or storage of casing slips has become a Difficulties; and at the drilling site, the used casing slips o...
