Embodiment 1

[0034] refer to Figure 1-4 , a four-way casing quick-installation structure applied to oil wells, the four-way casing quick-installation structure includes:

[0035] The casing body, the casing body includes a first casing 1, a second casing 2 and a connecting pipe 3, the diameter of the second casing 2 is larger than the diameter of the first casing 1, and the first casing 1 is connected to the second casing through a connecting mechanism The pipe 2 is connected, the connecting pipe 3 is fixedly connected with the end of the second casing 2 close to the first casing 1, and the diameter is larger than that of the second casing 2, and the connecting pipe 3 is sleeved on the first casing 1;

[0036] Limiting mechanism, the limiting mechanism includes a limit port 4, a limit block 5, a mounting block 6 and a spring 7, the two limit ports 4 are opened at opposite ends of the connecting pipe 3, and the two mounting blocks 6 are provided with installation The two ends of the sprin...

Embodiment 2

[0044] refer to Figure 5-7 The difference between this embodiment and the first embodiment is that the connecting pipe 3 and the first sleeve 1 are fixedly connected by a reinforcement mechanism. The reinforcement mechanism includes a bayonet 13, a bayonet slot 14 and a fixing rod 15. Open on both sides of the connecting pipe 3, and the connection line of the bayonet 13 is perpendicular to the connection line of the limit opening 4, the clamping slot 14 is relatively open on the surface of the first sleeve 1, and the fixing rod 15 is clamped inside the bayonet 13 and the clamping slot 14. ;

[0045] The side wall of the fixing rod 15 is provided with a plurality of strip-shaped grooves 16. The strip-shaped grooves 16 are fixedly connected with support feet 17. The support feet 17 are made of elastic material, and the expanded width is greater than the diameter of the limit opening 4. The strip-shaped grooves 16 is a place to place the support feet 17 when the support feet 17...

Abstract

The invention discloses a four-way casing quick-installation structure applied to an oil well. The four-way casing quick-installation structure comprises: a casing main body, the casing main body comprises a first casing, a second casing and a connection The diameter of the second sleeve is larger than the diameter of the first sleeve, the first sleeve is connected to the second sleeve through a connecting mechanism, and the connecting pipe is fixedly connected to the end of the second sleeve close to the first sleeve , the connecting pipe is sleeved on the first sleeve; the limit mechanism includes a limit port, a limit block, a mounting block and a spring, and the two limit ports are opened on two opposite sides of the connecting pipe. The two mounting blocks are both provided with mounting grooves, both ends of the spring are fixedly connected to the bottom of the mounting groove and the bottom of the limiting block respectively, and the size and shape of the limiting blocks are matched with the limiting opening and the mounting groove. The connection method of the present invention makes the process of installation and disassembly more convenient, and the operation is simple, and the construction personnel can also complete the process with bare hands.

Description

technical field [0001] The invention relates to the technical field of glass cleaning, in particular to a four-way casing quick-installation structure applied to oil wells. Background technique [0002] In the oil production operation, the casing spool, as the main component of the collection and distribution of the oil pipe and the casing, plays a key role in the structural stability of the entire oil production device. The lower part is connected to the hanging casing to seal the annular space of the oil casing. At present, the connection between different casings is often through flange connection, that is, two interconnected casings are fixedly installed with a flange on the end face, and the casings are connected through the connection between the two flanges. [0003] However, the existing sleeves connected by flanges are very cumbersome in connection, and it takes a lot of time for manual disassembly and assembly, which reduces the assembly speed of the four-way sleev...
