Description

Technical Field

[0001] The utility model relates to the technical field of petroleum, in particular to an oil casing head installer which is easy to adjust. Background Art

[0002] The casing head is used to fix the wellhead of the drilled well, connect the wellhead casing string, support the gravity of the technical casing and the oil layer casing, seal the annular space between the layers of pipes, provide a transition connection for the installation of blowout preventers, tubing heads, and Christmas trees, and through the two side ports on the casing head body, operations such as mud squeezing, monitoring, and adding balancing fluid can be carried out.

[0003] When installing the current casing head, the double male pipes are first installed at the bottom of the casing head, and then an electric hoist is used to connect the hook on the upper cover of the casing head to lift the casing head until the double male pipes can be connected to the wellhead casing string, and then the casing head is rotated to drive the double male pipes to engage with the wellhead casing string threads; then the casing head cover is removed, and then the casing buckle is installed on the casing head and the bolts are tightened, and then the buckle is lowered so that it engages with the casing buckle and rotates to complete the installation of the casing head.

[0004] The disadvantage of the existing installation method is that each time the casing head is installed, the upper cover and the casing buckle need to be removed and installed alternately on the casing head (to seal the casing head and prevent debris from entering the casing head); this method has low efficiency and high labor for the removal of bolts and the use of an electric hoist for the installation of the casing head; therefore, the present application proposes an easily adjustable oil casing head installer.

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides an easily adjustable oil casing head installer, comprising:

[0022] A movable bracket 3 is provided with two guide rails 1 below the bracket 3, and guide blocks 2 are slidably connected in the two guide rails 1. The bracket 3 is installed on the guide blocks 2. The part where the guide blocks 2 contact the guide rails 1 can be installed with pulleys to facilitate the movement of the guide blocks 2, thereby facilitating the adjustment of the position of the bracket 3; a through groove 4 is provided through the bracket 3, and the through groove 4 is a circular groove, and the oil casing head can be placed on the mounting plate 7 through the through groove 4.

[0023] A mounting assembly capable of guiding double male pipes; the mounting assembly comprises two driving members 5 mounted on a bracket 3, the driving member 5 being an electric push rod or a hydraulic cylinder, and the two driving members 5 working synchronously to achieve stable up and down movement of the mounting plate 7.

[0024] A connecting rod 10 is fixed to the output end of the driving member 5, and the bottom of the connecting rod 10 is connected to a detachable guided mounting plate 7, and a circular notch 8 is penetrated by the mounting plate 7. The circular notches 8 on the two mounting plates 7 are located on the same circumference, and the center of the circular notch 8 is coaxially arranged with the through groove 4; further explanation: four guide rods 6 are fixed to the upper end of the mounting plate 7, and the guide rods 6 pass through the bracket 3 and are slidably connected thereto, so that when the connecting rod 10 is separated from the mounting plate 7, the stable downward movement of the mounting plate 7 can also be ensured under the action of the guide rods 6.

[0025] The detachable mounting plate 7 is explained as follows: a connecting sleeve 11 is fixed on the mounting plate 7, a connecting rod 10 is slidably connected in the connecting sleeve 11, a locking groove 12 is provided on the connecting rod 10, a sliding locking rod 14 is passed through the connecting sleeve 11, the locking rod 14 is slidably connected in the locking groove 12, a hand-pull block 13 is fixed on the locking rod 14, a spring 9 is fixed on the hand-pull block 13 and the connecting sleeve 11, and the hand-pull block 13 is pulled by the spring 9 so that the locking rod 14 is tightly stuck in the locking groove 12, thereby ensuring a stable connection between the connecting rod 10 and the mounting plate 7; when disassembling, only the hand-pull block 13 needs to be pulled to drive the locking rod 14 out of the locking groove 12.

[0026] When installing the oil casing head, the double male pipes pass through the two circular notches 8 and move against each other. The driving member 5 drives the mounting plate 7 downward to guide the double male pipes. After installation, the connecting rod 10 is separated from the mounting plate 7 and the mounting plate 7 is removed. For further detailed explanation, the oil casing head with the double male pipes installed is placed on the mounting plate 7. At this time, the double male pipes are located in the two circular notches 8. At this time, the upper end of the oil casing head is connected to a casing buckle;

[0027] Then the staff pushes the support 3, the guide block 2 slides on the guide rail 1 until the double male pipe is opposite to the well mouth; the driving member drives the mounting plate 7 to move downward to make the double male pipe abut against the oil pipe, then rotates the petroleum casing head to drive the double male pipe to rotate, so that the thread at the bottom of the double male pipe is engaged in the petroleum system, then the driving member 5 is started to move downward to make the two mounting plates 7 move downward to make them not contact with the petroleum casing head, the double male pipe can be guided through the mounting plate 7, so that the petroleum casing head is rotated to drive the double male pipe to rotate and move downward, so that the double male pipe is installed in the petroleum system, then the upper tongs are placed downward to make them engage with the casing upper tongs and rotate to ensure the torque marking, which is the prior art; after the installation of the casing head is completed, the casing upper tongs are removed, and the upper end of the petroleum casing head is measured horizontally, and the installation of the petroleum casing head is completed.

[0028] Then the hand pulls the block 13 to make the lock rod 14 disengage from the lock groove 12, at this time, the connecting rod 10 is no longer limited, moves downward to the mounting plate 7 to make the guide rod 6 separate from the support 3, so that the mounting plate 7 can be removed, and then is installed on the connecting rod 10 again for next use.

[0029] Compared with the prior art, the utility model discloses the installation and removal of the upper cover are omitted, the working steps and the work amount are reduced, and the double male pipe can be guided to the casing head, so that stable connection between threads during thread engagement is ensured, and serious thread wear or damage caused by the inclination of the double male pipe during thread engagement is avoided.

[0030] Finally, it is pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model and not to limit, although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions of the utility model, and all should be covered in the claim range of the utility model.
