Two groups of connecting grooves 501 are opened on one side of the top of the fixing sleeve 3. A spring groove 502 is opened on one side of the connecting groove 501. A spring 503 is arranged inside the spring groove 502. One end of the spring 503 is fixedly connected to the spring groove 502 and the other end is fixedly connected to the bayonet 504. Two groups of connecting blocks 505 are fixedly connected to one side of the top of the fixing sleeve 3. The inner wall of the connecting groove 501 is slidably connected to A connecting block 505 is provided with a slot 506 on one side of the connecting block 505, one end of the bayonet 504 cooperates with the slot 506, and the connecting sleeve 4 is inserted into the connecting slot 501 through the connecting block 505. At this time, the surface of the connecting block 505 will squeeze the bayonet 504 and the spring 503. When the connecting block 505 is in a suitable position, the spring 503 resets and pushes the bayonet 504 into the interior of the slot 506, so that the connecting sleeve 4 is fixed to the fixing sleeve 3 through the connecting block 505, thereby facilitating the installation of the fixing sleeve 3 and the connecting sleeve 4 on the surface sleeve 1.

[0026] In one embodiment, Figure 5 As shown, the diameter of the spring slot 502 matches the diameter of the spring 503 . When the spring 503 is extended or retracted, the spring slot 502 will limit the spring 503 to prevent the spring 503 from shaking.

[0027] In one embodiment, Figure 3As shown, the inner wall size of the connecting groove 501 is consistent with the outer wall size of the connecting block 505. When the connecting block 505 slides inside the connecting groove 501, the connecting groove 501 can limit the sliding of the connecting block 505 to prevent the connecting block 505 from shaking inside the connecting groove 501.

[0028] In one embodiment, Figure 3 As shown, a threaded hole 6 is provided at one end of the connecting groove 501, and a bolt 7 is threadedly connected to the inner wall of the threaded hole 6. One end of the bolt 7 cooperates with the connecting block 505. When the bolt 7 is turned, the bolt 7 passes through the threaded hole 6 and is threadedly connected to the connecting block 505, so that the fixing sleeve 3 and the connecting sleeve 4 can be better fixed together.

[0029] In one embodiment, Figure 4 As shown, a fixing groove 8 is provided at the bottom of the fixing sleeve 3, a fixing block 9 is fixedly connected to the bottom of the connecting sleeve 4, and a fixing block 9 is slidably connected to the inner wall of the fixing groove 8, so that the connecting sleeve 4 can be inserted into the fixing groove 8 through the fixing block 9, thereby preventing the bottom of the connecting sleeve 4 from shaking at will.

[0030] In one embodiment, Figure 1 As shown, a first ring sleeve groove glue injection hole 10 is opened on one side of the top of the fixing sleeve 3, and a second ring sleeve groove glue injection hole 11 is opened on one side of the top of the connecting sleeve 4. The sealing agent can be injected into the fixing sleeve 3 and the connecting sleeve 4 through the first ring sleeve groove glue injection hole 10 and the second ring sleeve groove glue injection hole 11, so that the fixing sleeve 3 and the connecting sleeve 4 are fixed on the surface casing 1, and then the high-pressure sealant is relied on to prevent the medium in the surface casing 1 from leaking and spilling on the ground, and the colloid can be kept in the fixing sleeve 3 and the connecting sleeve 4, avoiding the cementing material spilling on the ground during the grouting and cementing process to cause environmental pollution.

[0031] In one embodiment, Figure 4 As shown, the surface casing 1 is fixedly connected to the oil layer casing 2, a cement injection hole 12 is opened on the bottom side of the surface casing 1, and a cement injection pipe interface 13 is opened on the top side of the fixed sleeve 3. The cement injection pipe is inserted into the cement injection hole 12 through the cement injection pipe interface 13, and cement is injected into the surface casing 1 and the oil layer casing 2 through the cement injection pipe, thereby ensuring that the mortar can accurately fill the missing parts of the cement ring in the surface casing 1 and the oil layer casing 2.

[0032] Working principle: The above embodiment discloses a ash injection packaging structure that is easy to install. When in use, the fixing sleeve 3 is sleeved on the surface sleeve 1, and then the connecting sleeve 4 is inserted into the connecting groove 501 through the connecting block 505. At this time, the surface of the connecting block 505 will squeeze the bayonet 504 and the spring 503. When the connecting block 505 is in a suitable position, the spring 503 resets and pushes the bayonet 504 into the interior of the bayonet groove 506, so that the connecting sleeve 4 is fixed to the fixing sleeve 3 through the connecting block 505. Tighten the bolt 7, the bolt 7 passes through the threaded hole 6 and is threadedly connected to the connecting block 505, so that the fixing sleeve 3 and the connecting sleeve 4 can be better fixed together, thereby facilitating the installation of the fixing sleeve 3 and the connecting sleeve 4 on the surface sleeve 1, and inject the sealing agent through the first ring sleeve groove injection hole 10 and the second ring sleeve groove injection hole 11 is injected into the fixing sleeve 3 and the connecting sleeve 4, so that the fixing sleeve 3 and the connecting sleeve 4 are fixed on the surface casing 1, and then the high-pressure sealant is used to prevent the medium in the surface casing 1 from leaking out and spilling on the ground, and the colloid can be kept in the fixing sleeve 3 and the connecting sleeve 4, so as to avoid the cementing material spilling on the ground and causing environmental pollution during the grouting and cementing process. Then the cement injection pipe is inserted into the cement injection hole 12 through the cement injection pipe interface 13, so that the cement injection pipe can smoothly enter the annulus of the wellhead B at a depth of 50 to 100 meters, and the surface casing 1 and the oil layer casing 2 are injected with cement through the cement injection pipe, so that the mortar can accurately fill the missing part of the cement ring in the annulus within 50 to 100 meters. The cement injection pipe interface 13 is set so that the cement injection pipe can be smoothly recovered and taken out, so as to avoid the cement injection pipe sticking to the oil layer casing 2 and affecting the subsequent use.
