Description

Technical Field

[0001] This utility model relates to the field of oil well trees, specifically a split-type oil well tree. Background Technology

[0002] A wellhead tree is a wellhead device used to extract oil in flowing wells and mechanically operated wells. It is the main equipment at the top of an oil and gas well for controlling and regulating oil and gas production. It mainly consists of three parts: casing head, tubing head, and the wellhead (or production tree) body. Most existing wellheads are integral wellheads.

[0003] In the prior art, the integral wellhead can only be fixed in one position for extraction during use, and the angle and position cannot be adjusted, resulting in low extraction efficiency and long extraction time. Therefore, this utility model proposes a split wellhead to solve the above problems. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a split-type oil well tree, including a fixed base 1, a circular groove 2 at the upper end of the fixed base 1, a fixed column 3 fixedly installed in the middle of the circular groove 2, a connecting column 4 on the side of the fixed column 3, an oil well tree body 8 at the upper end of the connecting column 4, and a bolt 20 at the bottom end of the oil well tree body 8; the surface of the connecting column 4 has several sets of threaded holes 21, and the side of the connecting column 4 is provided with roller 2 15 and roller 14; the inner wall of the fixed base 1 has a sliding groove 12, and roller 2 15 is slidably installed in the sliding groove 12;

[0021] In use, align the bottom flanges of the two sets of wellhead bodies 8 with the two sets of connecting columns 4, align the threaded holes 11 on the fixing blocks 9 fixed on one side of the wellhead body 8 with the threaded holes 5, and then thread the bolts 20 through the flanges and thread them to the threaded holes 21. Thread the bolts 10 to the threaded holes 5 and 10, and fix the two sets of wellhead bodies 8 on the two sets of connecting columns 4 respectively. Oil production can then be carried out. Remove the bolts 10 to push the wellhead body 8 to move on the fixed base 1. At this time, the rollers 15 slide in the slide groove 12 and the rollers 14 slide in the slide groove 13, which can push the wellhead body 8 to a suitable position before oil production can be carried out. The two sets of wellheads can carry out oil production at the same time, which improves the extraction efficiency to a certain extent and saves time.

[0022] Example 2: Based on Example 1, in order to facilitate the fixing of the two sets of oil well bodies 8, a fixing block 9 is fixedly installed on one side of the bottom of each set of oil well bodies 8. The surface of the fixing block 9 is provided with threaded hole 11, and the upper surface of the fixing base 1 is provided with several sets of threaded holes 5. A bolt 10 is provided at the upper end of the fixing block 9. The bolt 10 is threadedly connected to the threaded hole 5 and the threaded hole 5. The bolt 20 is located at the flange position at the bottom of the oil well body 8. The bolt 20 passes through the flange and is threadedly connected to the threaded hole 21.

[0023] Align the bottom flanges of the two sets of tree bodies 8 with the two sets of connecting columns 4. Align the threaded holes 11 on the fixing blocks 9 that are fixedly installed on one side of the tree body 8 with the threaded holes 5. Then, use bolts 20 to thread the flanges through the flanges and thread the bolts 21. Thread bolts 10 are threaded to threaded holes 5 and 15. Fix the two sets of tree bodies 8 on the two sets of connecting columns 4 respectively.

[0024] Example 3: Based on Example 2, to facilitate the movement of the two sets of oil well bodies 8, an annular groove 2 7 is provided on the surface of the fixed column 3. A sliding groove 2 13 is provided on one side of the annular groove 2 7, which is connected to the sliding groove 2 13 on one side, and the other side of the annular groove 2 7 penetrates the fixed column 3. An annular groove 1 6 is provided on one side of the sliding groove 1 12, which is connected to the sliding groove 1 12 on one side, and the other side of the annular groove 1 6 penetrates the inner wall of the fixed base 1. Two sets of connecting columns 4 are provided, and rollers 2 15 and rollers 1 14 are symmetrically installed about the connecting columns 4. Roller 15 has a mounting hole on one side wall, and bearing 18 is fixedly installed in the mounting hole. Fixing rod 17 is fixedly installed on the inner ring surface of bearing 18. The other end of fixing rod 17 is fixedly installed on one side of connecting column 4. Roller 14 has a mounting hole on one side wall, and bearing 19 is fixedly installed in the mounting hole. Fixing rod 16 is fixedly installed on the inner ring surface of bearing 19. The other end of fixing rod 16 is fixedly installed on one side of connecting column 4. Roller 14 is slidably installed in slide groove 13. The diameter of roller 14 is larger than that of roller 15.

[0025] Two sets of wellhead bodies 8 are fixed to two sets of connecting columns 4 respectively. Oil production can then be carried out. Bolt 10 is removed, and the wellhead body 8 can be moved on the fixed base 1. At this time, roller 15 slides in groove 12 and roller 14 slides in groove 13. Because the wellhead body 8 needs to be moved, roller 14 and roller 15 need to slide in groove 12 and groove 13 respectively when the connecting column 4 is moved. Since the straight distance between groove 13 and the fixed column 3 is greater than that between groove 12 and roller 14, the diameter of roller 14 is slightly smaller than that of roller 15, which makes it easier to move the wellhead body 8. The wellhead body 8 can be pushed to a suitable position and then bolt 10 can be used to fix it before oil production can be carried out. The two sets of wellheads can be used for oil production at the same time or separately.

[0026] In actual use, bolt 20 passes through the flange and is threaded into threaded hole 3 21. Bolt 10 is threaded into threaded holes 1 and 5. The two sets of production tree bodies 8 are fixed on the two sets of connecting columns 4 respectively. Oil production can then be carried out. Bolt 10 can be removed to push the production tree body 8 on the fixed base 1. The production tree body 8 can be pushed to a suitable position before oil production can be carried out. The two sets of production trees can carry out oil production at the same time, which improves the extraction efficiency to a certain extent and saves time.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
