In the description of the present invention, it is to be noted that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and should not be construed as limiting the present invention.
Example 1
As shown in fig. 1-2, an automatic paraffin cleaner includes,
the self-rotating power part is arranged in the upper joint 1;
in particular, the upper joint 1 is used for connecting a sucker rod, and provides axial movement power for the whole paraffin cleaner on one hand and pressure fluid on the other hand.
A self-rotating power part is arranged in the upper joint 1 and used for providing rotating power for the paraffin removal column. In the present embodiment, the self-rotating power member includes a bypass valve assembly 2, a screw motor 3, and a universal joint assembly 4, which corresponds to the upper half of the screw drill.
Specifically, the paraffin removal column 6 is a hollow cylinder, one end of the paraffin removal column is connected with the universal assembly 4 of the spinning rotating part, and the other end of the paraffin removal column is a sealing section. A protective shell 5 is arranged at the joint between the paraffin removal column 6 and the universal assembly 4, and the protective shell 5 has the following functions: the joint of the paraffin removal column 6 and the universal assembly 4 is protected, and the scraped paraffin blocks and other solid phases are prevented from entering the universal assembly 4 and the screw motor 3, which brings trouble to the operation of a spinning rotating force part, so that a rotating sealing part 8 is arranged between one end of the protective shell 5, which is far away from the universal assembly 4, and the paraffin removal column 6; so that the fluid flowing through the self-rotating power part can completely enter the paraffin removal column 6, and for this reason, a plurality of liquid inlet holes 7 are arranged on the paraffin removal column 6 arranged inside the protective shell 5, and the fluid passing through the self-rotating power part can enter the paraffin removal column 6 through the liquid inlet holes 7.
As shown in fig. 3, the hot fluid has a better auxiliary effect on paraffin removal than the cold fluid, and meanwhile, if the hot fluid is injected on the ground, the hot fluid dissipates heat more and to a greater extent in the flowing process. Therefore, in this embodiment, the fluid is heated by providing the heating layer 15 in the upper connecting head side wall and the protection casing side wall 501, so that the heat loss can be effectively reduced. Fig. 3 discloses the arrangement of the heating layer 15 on the protective shell 5, and the arrangement of the heating layer 15 of the upper connector is the same.
On the paraffin removal column 6, a first spray head 13, a paraffin removal scraper 12, a vibration paraffin removal brush 11 and a third spray head 10 are sequentially arranged from the tail end of the paraffin removal column 6 to the direction of the universal assembly 4. Wherein, the first nozzle 13 is arranged at the tail end of the paraffin removal column 6, and the other parts are arranged in sequence. The first spray head 13 and the third spray head 10 have an inclination angle of 0-60 degrees with the paraffin removal column 6, and the direction of the rotary thrust generated to the paraffin removal column 6 by the fluid flowing through the first spray head 13 and the third spray head 10 is the same as the rotation direction of the self-rotating power part. Since the screw motor 3 and its accessories are used as the spin rotating member in this embodiment, the rotation speed of the screw motor 3 itself is relatively slow, so that when the directions of the first nozzle 13 and the third nozzle 10 are designed, it is necessary to reduce the influence of the thrust generated by the liquid discharge of the nozzles on the rotation of the paraffin removal column 6 as much as possible. In the embodiment, the first spray head 13 and the third spray head 10 both have an inclination angle of 0-60 degrees with the paraffin removal column 6, meanwhile, the central axes of the first spray head 13 and the third spray head 10 and the paraffin removal column 6 are not on the same plane, and the specific inclination of the first spray head 13 and the third spray head 10 is related to the rotating direction of the self-rotating power part. When the inclination angle is 0 degrees, the first spray head 13 or the third spray head 10 is tangent to the paraffin removal column 6, and the effect is best, so that the rotation of the paraffin removal column 6 is promoted; when the inclination angle is 60 degrees, the first spray head 13 or the third spray head 10 cannot influence the rotation of the paraffin removal column 6, but the fluid sprayed on the wall surface is more concentrated, and meanwhile, the spraying distance of the first spray head 13 or the third spray head 10 is shorter, so that the wall surface washing effect is stronger; when the inclination angle is larger than 60 degrees, although the spraying distance of the first spray head 13 or the third spray head 10 is closer, the washing effect on the wall surface is stronger, but the spraying distance can cause negative influence on the rotation of the paraffin removal column 6, so that the paraffin removal efficiency is reduced, and the stability of the whole automatic paraffin remover is reduced.
In the present embodiment, the first nozzle 13 and the third nozzle 10 have different functions in wax removal: the first spray head 13 is arranged at the bottom of the paraffin removal column 6, and the sprayed fluid firstly contacts the wall surface which is not cleaned by the paraffin removal scraper 12 and the paraffin removal vibrating brush 11 or the wall surface which is being treated by the paraffin removal scraper 12, so that the first spray head 13 firstly washes the paraffin deposition wall surface through high-speed fluid, and washes the paraffin particles which are not firmly combined with the wall surface, thereby weakening the acting force between the residual paraffin particles and the wall surface, and leading the paraffin removal scraper 12 and the vibrating paraffin removal brush 11 to more easily remove the paraffin deposition on the wall surface. The third spray head 10 is arranged between the vibration paraffin removal brush 11 and the universal assembly 4, fluid sprayed by the third spray head 10 contacts with the wall surface treated by the paraffin removal scraper 12 and the paraffin removal vibration brush 11, or the wall surface treated by the paraffin removal vibration brush 11, therefore, the third spray head 10 is more effective in washing the wall surface to prevent a small amount of residual wax particles from being bonded on the wall surface, and if the third spray head 10 is not arranged, after a small amount of wax particles are bonded on the wall surface after paraffin removal, the paraffin precipitation speed of the wall surface is rapidly increased in the subsequent production process.
Meanwhile, in the embodiment, a plurality of liquid inlet holes 7 are further formed in the paraffin removal column 6 arranged in the protective shell 5, in order to further increase the liquid discharging speed of the first spray head 13 and the third spray head 10 and better perform paraffin removal on an oil production pipe and the like, a certain inclination angle is also formed between the liquid inlet holes 7 and the paraffin removal column 6, and the inclination angle of the liquid inlet holes 7 is completely the same as that of the first spray head 13. After fluid enters the paraffin removal column 6 through the liquid inlet hole 7, the fluid immediately enters a rotating state, the fluid passes through the first spray head 13 and the third spray head 10 at a higher speed, and paraffin deposition side walls such as an oil production pipe and the like are more fully cleaned.
In this embodiment, wax deposits on the wall surface of the pipe including the production string are removed by the wax removal scraper 12 and the wax removal vibrating brush 11. The paraffin removal blade 12 may be a conventional paraffin removal blade currently available on the market, and in this embodiment, a spiral blade is used. Generally speaking, the paraffin removal scraper 12 can remove large-particle paraffin deposit on the surface to be avoided, but the effect is poor for the paraffin deposition degree (namely, a thinner paraffin deposition layer) or even the paraffin deposition degree cannot be treated, so that the paraffin removal vibrating brush 11 is additionally arranged behind the paraffin removal scraper 12 in the embodiment, and the paraffin removal vibrating brush are combined to be used for cleaning the paraffin deposit on the wall surface more fully.
As shown in fig. 2 and 4, the paraffin removal vibration brush 11 is composed of a brush handle 111 and bristles 112, the brush handle 111 is fixed on the outer side wall of the paraffin removal column 6, a vibration plate 114 is arranged inside the brush handle 111, meanwhile, in order to supply power to the vibration plate 114, a power source 113 is arranged at the bottom of the brush handle 111, and in general, the power source 113 is a battery. The bristles 112 are fixedly arranged on the upper part of the brush handle 111, generally speaking, at least one fifth of the bristles 112 are coated with an abrasion resistant coating 1122, and the abrasion resistant coating 1122 is arranged on the upper part of the bristles 112; at least one-half of the bristles 112 are coated with an oleophobic coating 1121, and the oleophobic coating 1121 is disposed on the lower portion of the wear resistant coating 1122. In this embodiment, the wear-resistant coating 1122 is provided on one fifth of the top of the bristle 112, the remaining portion of the bristle 112 is provided with the oleophobic coating 1121, and the wear-resistant coating 1122 provided on the top of the bristle 112 substantially takes into account that the bristle 112 has a better effect due to the wear-resistant coating 1122 provided on the top thereof during long-term operation. The reason why the oleophobic coating 1121 is disposed on the bristles 112 is that when the vibration wax removing brush 11 is operated for a long time, a part of the wax block inevitably adheres to the bristles 112, which reduces the efficiency of the vibration wax removing brush 11, and the oleophobic coating 1121 is disposed to effectively prevent the wax block from adhering to the bristles 112. The vibrating reed 114 is provided to allow the bristles 112 to perform a wax removal operation in a state of continuous vibration, thereby increasing the wax removal efficiency.
In this embodiment, the bristles 112 are made of a material having a certain strength, such as a high-strength steel wire. Meanwhile, the distance from the tail end of the brush hair 112 of the vibration paraffin removal brush 11 to the paraffin removal column 6 is larger than the distance from the tail end of the paraffin removal scraper 12 to the paraffin removal column 6 in consideration of the function of the vibration paraffin removal brush 11.
Referring to fig. 1, in the present embodiment, a spiral scraper is used as the paraffin removal scraper 12, but during the operation of the paraffin removal scraper 12, the contact area between the paraffin removal scraper 12 and the wall surface is large, the calorific value is high under high-speed rotation, and under long-time high-temperature operation conditions, the efficiency of the paraffin removal scraper 12 is reduced and is even easily damaged. Simultaneously, the wax granule adheres easily on paraffin removal scraper 12, consequently, still is provided with a plurality of second shower nozzles 14, and the nozzle of second shower nozzle 14 is towards paraffin removal scraper 12, is used for taking away the heat on paraffin removal scraper 12 on the one hand, reduces its temperature, and on the other hand can wash paraffin removal scraper 12, avoids a large amount of wax granules to adhere on paraffin removal scraper 12, causes the influence for subsequent paraffin removal work.
Still be provided with on whole automatic paraffin cleaner and right piece 9, right piece 9 and can set up on top connection 1 or clear wax column 6, in this embodiment, right piece 9 sets up on clear wax column 6.
When the automatic paraffin cleaner is used, the upper joint is connected with a sucker rod, the automatic paraffin cleaner is put into a paraffin deposition part, pressure fluid such as low-viscosity crude oil is injected through the sucker rod, after the pressure of the pressure fluid is increased, the bypass valve is opened, the fluid enters the screw motor and drives the screw motor to rotate, the paraffin removal columns rotate together under the action of the universal assembly, and the whole automatic paraffin cleaner starts to work. Pressure fluid enters a space between the protective shell and the paraffin removal column through the universal assembly, and under the action of the rotary sealing element, the pressure fluid can only enter the paraffin removal column through the liquid inlet hole.
After the pressure fluid enters the paraffin removal column, the liquid inlet hole has a certain inclination angle, so that the flowing mode of the pressure fluid in the paraffin removal column is rotational flow, the pressure fluid is discharged through the first nozzle, the second nozzle and the third nozzle, and meanwhile, the pressure fluid plays a promoting role in the rotation of the paraffin removal column in the discharging process.
After the pressure fluid is discharged through the first spray head, the pressure fluid impacts the wax deposition wall surface to avoid wax particles with unstable upper structures from being washed away, then the wax deposition wall surface is scraped by the wax cleaning scraper, the wall surface cleaned by the wax cleaning scraper is further cleaned by the vibration wax cleaning brush, a wax block is prevented from being cleaned to the maximum extent, the wall surface cleaned by the vibration wax cleaning brush is prevented from being washed, and wax with small particles is prevented from being deposited on the wall surface.
In the whole paraffin removal process, the pressure fluid is heated under the action of the heating layers of the upper joint and the side wall of the protective shell, so that the paraffin removal effect is better.
In a certain oil well of kravayi in Xinjiang, the wax content is 7.1%, the conventional wax cleaner is used for cleaning wax (namely, a simple spiral wax cleaner is equivalent to the wax cleaning scraper in the embodiment), the wax cleaning period is 115 days, after the automatic wax cleaner in the embodiment is used for cleaning wax, the automatic wax cleaner runs smoothly for 180 days till now, and the automatic wax cleaner in the embodiment is explained to be used, so that the automatic wax cleaner has a good wax cleaning effect, and meanwhile, the wax is relatively thorough, and the wax is not easy to precipitate after the wax is cleaned.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the embodiments of the present invention are included in the scope of the present invention.
