Description
Technical Field
The utility model belongs to the technical field of wellhead devices of oil extraction wells in oil fields, and particularly relates to an oil pipe rotator suitable for being transformed by a production well.
Background
In oilfield production, an oil pipe in an oil production well has a eccentric wear phenomenon, and the eccentric wear greatly shortens the service life of the oil pipe. In order to solve the problem of oil pipe eccentric wear, technicians have developed oil pipe rotators that avoid oil pipe eccentric wear by constantly rotating the oil pipe.
The utility model patent number CN202220244132.9 discloses an automatic oil pipe rotator with built-in impellers, which takes kinetic energy of flowing liquid in an oil pipe as driving force to drive the built-in impellers to rotate, and then the rotating motion of the impellers is converted into the rotating motion of the oil pipe through a turbine worm speed reduction transmission mechanism, so that the automatic rotation of the oil pipe is realized, and the automatic oil pipe rotator has higher practicability and popularization and application values.
However, while the tubing swivel described above has many advantages, it also has significant drawbacks:
when the oil pipe rotator is installed, the oil pipe rotator needs to be connected below a large four-way joint at a wellhead, and the height of a wellhead Christmas tree can be objectively increased. For new wells, the increase of the height of the christmas tree does not bring obvious adverse effect, but for a large number of existing production wells in use, the shape and trend of the wellhead process flow are matched with the height of the christmas tree, and if the oil pipe rotator is required to be additionally arranged, the wellhead process flow is necessarily thoroughly modified. During transformation, the wellhead technological process is required to be redesigned and manufactured, the fire welding is required, and the production stopping is required, so that the operation is complex, the transformation cost is high, and the purchasing will of oilfield users is low. Therefore, there is a need for improvements to the tubing swivel described above.
Disclosure of Invention
The utility model designs the oil pipe rotator suitable for the reconstruction of the production well, and the oil pipe rotator can be conveniently installed in the production well by adopting an alternative installation mode without damaging the original wellhead technological process.
The technical problems solved by the utility model are realized by adopting the following technical scheme:
the oil pipe rotator suitable for the reconstruction of a production well comprises a base, wherein an oil pipe hanger is arranged in the center of the base, an impeller assembly and a speed reduction transmission mechanism are used for driving the oil pipe hanger to rotate, a rotatable mandrel is arranged in the center of the oil pipe hanger, and an oil pipe is connected to the lower end of the mandrel;
the height of the base is the same as that of the large four-way joint at the original wellhead;
the side surface of the base is provided with a left branch pipe and a right branch pipe, and the space in the two branch pipes is communicated with the space above the oil pipe hanger in the base; the vertical height and the extension length of the two branch pipes on the base are matched with the original wellhead process flow.
As a preferable scheme, the upper end and the lower end of the base are respectively provided with an upper flange and a lower flange, the base replaces the original large four-way at the wellhead, and the base is connected to the position of the original large four-way through the upper flange and the lower flange.
Preferably, the base is provided with a locking bolt for locking the tubing hanger, and the locking bolt is located below the branch pipe.
The beneficial effects of the utility model are as follows:
in order to install the oil pipe rotator and not increase the height of the wellhead christmas tree, the utility model creatively adopts the design thought of replacement installation, perfectly fuses the oil pipe rotator with the large four-way on the original christmas tree in structure and function, and the improved oil pipe rotator is enabled to have the same height as the large four-way on the original wellhead by additionally arranging the branch pipes on the existing oil pipe rotator, so that the utility model can be installed at the installation position of the large four-way on the original wellhead and has the function of the large four-way on the original wellhead. By this improvement, the utility model can be directly applied to existing production wells in large numbers without modifying the wellhead process flow, so that the utility model is more easily accepted by oilfield clients.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Examples:
as shown in fig. 1, the present embodiment includes a base 7, a tubing hanger 4 is mounted at the center of the base 7, an impeller assembly 3 and a reduction gear mechanism (not shown) for driving the tubing hanger 4 to rotate are provided at the center of the tubing hanger 4, a rotatable mandrel 8 is provided at the center of the tubing hanger 4, and a tubing is connected to the lower end of the mandrel 8. The impeller assembly 3 is mounted in a mounting hole in the base 7 and the impeller assembly 3 is located above the tubing hanger 4. The speed reducing transmission mechanism adopts a turbine worm speed reducing mechanism.
The above is a structure already existing in the existing oil pipe rotator, and will not be described here again.
As shown in fig. 1 and 2, the present utility model differs from the prior art mainly in three ways: firstly, the height of the base 7 is the same as that of a large four-way valve at the original wellhead; secondly, two branch pipes 1 are arranged on the side face of the base 7, the space in the two branch pipes 1 is communicated with the space above the oil pipe hanger 4 in the base 7, and thirdly, the vertical height and the extension length of the two branch pipes 1 on the base 7 are matched with the original wellhead technological process. The oil pipe rotator is provided with the function of a large cross joint of a wellhead by additionally arranging the branch pipe 1 on the existing oil pipe rotator, and the oil pipe rotator is directly arranged at the position of the large cross joint of the original wellhead by adopting the same connecting structure as the large cross joint of the original wellhead at the upper end and the lower end of the oil pipe rotator and the tail end of the branch pipe 1 and enabling the height of the oil pipe rotator to be the same as that of the large cross joint of the original wellhead. Therefore, through the improvement, the oil pipe rotator can directly replace the original wellhead large four-way joint, and the oil pipe rotator can be conveniently and quickly installed in a production well by adopting the replacement installation mode without modifying the existing wellhead process flow.
In the utility model, as shown in fig. 1, the upper and lower ends of the base 7 are respectively provided with the upper flange 2 and the lower flange 6, and when the installation is performed, after the original large four-way at the wellhead is removed, the original large four-way can be conveniently connected at the position of the original large four-way through the upper flange 2 and the lower flange 6, so that the installation process is short in time consumption and labor-saving, and the production cannot be influenced. In the concrete implementation, threaded holes can be machined at the upper end and the lower end of the base 7 to replace the upper flange 2 and the lower flange 6, so that the connection function is realized.
