The whole density is reduced by arranging the bubble structure in the rubber ball, the volume of the ball cannot be increased, and the condition of blocking a pipe cannot occur; the manufacturing method is simple, the gravity center can be ensured not to be greatly deviated, and the wax scraping function of the existing wax removing ball can be realized.
Description
Technical Field
The utility model relates to a defeated equipment field of crude oil collection, concretely relates to paraffin removal ball.
Background
In the oil recovery technology in current oil field, in the pipeline oil transportation operation from beam-pumping unit well head christmas tree to the joint station, often lead to oil pipeline inner wall to become littleer and smaller because of the wax deposition gradually because of containing in the crude oil, crude oil can not normally reach the joint station, therefore, oil production factory worker need regularly add the rubber paraffin removal ball at the oil production well head christmas tree, utilize crude oil self pressure in the pipeline, promote the paraffin removal ball to remove to the joint station pond oil mouth, utilize the outer surface that the rubber ball has certain hardness to reach the effect of scraping the wax clearance pipeline, utilize rubber to have certain elasticity again simultaneously, be unlikely to paraffin removal ball card and die at certain position in the pipeline. The density of the paraffin removal ball generally reaches 1.2 to 1.3g/cm3The specific gravity of the rubber paraffin removal ball is larger than that of oil, so the rubber paraffin removal ball pressed in through a well head reaches the lower part of crude oil after being pressed to an oil drainage port,is not easy to be found. In actual production, the oil extraction worker does not know whether the paraffin removal ball reaches the oil drainage port or not, and does not know which well pressed the paraffin removal ball reaches the oil drainage port. The oil extraction worker can not know the running track and speed of the paraffin removal ball and whether the paraffin removal ball reaches the oil drainage port or not. Workers need to use tools to fish out the paraffin removal ball from the oil drainage port, and the operation environment is severe. In order to solve the problem, the patent with the application number of 201821580397.6, namely the low-density paraffin removal ball for reducing the back pressure and the patent with the application number of 201821581147.4, namely the low-density paraffin removal ball, adopt a mode that a stainless steel hollow ball and a solid wood ball are wrapped by rubber to ensure that the density of the paraffin removal ball is as low as 0.85g/cm3However, by adopting the structure, the steel ball is hollow, the steel ball is generally formed by splicing, specifically, the two hemispheres are firstly assembled, and then the welding wires of the welding machine are used for connecting the interfaces of the two hemispheres to form a complete closed hollow steel ball. During welding, the prior art cannot ensure that the inner part of the steel ball connecting part is smooth.
It has the following drawbacks:
1. the manufacturing process is complex.
2. The stainless steel hollow ball and the solid wood ball are adopted, and when the stainless steel hollow ball and the solid wood ball are coated and vulcanized by rubber, the stainless steel hollow ball and the solid wood ball cannot be positioned, so that the centers of gravity of most of the stainless steel hollow ball and the solid wood ball are not in the center of the whole paraffin removal ball. The stainless steel hollow balls and the solid wooden balls are easy to run on the surface of the paraffin removal ball, and the function of the paraffin removal ball is influenced.
3. Because two different materials are adopted, the oil pipeline is easy to delaminate, and the potential danger of blockage is brought to the oil pipeline.
4. The above scheme is theoretically possible, but in practice it is desirable to achieve 0.85g/cm3Is not practical. Theoretically, the larger the hollow proportion in the sphere is, the lower the density of the whole paraffin removal ball is, but in the actual situation, the hollow stainless steel ball and the solid wood ball are required to have larger diameters and are easy to be eccentric, the stainless steel and the wood part are exposed, the exposed part is not oil-resistant, the pipe is easy to be blocked, and the function of the paraffin removal ball is lost.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned technical problem and provide a paraffin removal ball.
The utility model discloses a following technical scheme realizes:
a paraffin removal ball comprises a rubber ball body, wherein a bubble structure is arranged in the rubber ball body, so that the density of the rubber ball body is less than 0.845g/cm 3. The density of the paraffin removal ball is smaller than the oil density, the paraffin removal ball can well float on the surface of oil, the density of a rubber ball body is reduced by adopting an internal bubble structure, the paraffin removal ball can be manufactured by adopting the existing foaming vulcanization and foaming injection molding technology, and the manufacturing method is simple and free of the problem of gravity center offset. The whole paraffin removal ball of this scheme is the rubber material, does not have the layering phenomenon, and the wholeness is good, long service life. This scheme accessible foaming vulcanization, the technique of moulding plastics produce the bubble structure in rubber ball, make paraffin removal ball reliably float in the oil level when density reduction, can not block up the pipe.
Compared with the prior art, the utility model, following advantage and beneficial effect have at least:
1. the utility model discloses a set up the bubble structure in the rubber spheroid and reduce whole density, the wholeness is good, long service life.
2. The utility model discloses a set up the bubble structure in the rubber spheroid and reduce whole density, manufacturing method is simple and can guarantee that the focus does not take place the skew, can fine realization paraffin removal ball scrape the wax function.
3. The utility model discloses a process into various colours and sign, can prepare to confirm time, the orbit of paraffin removal ball operation.
Drawings
The accompanying drawings, which are included to provide a further understanding of the embodiments of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principles of the invention.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.
Example 1
A paraffin removal ball as shown in figure 1 comprises a rubber ball body 1, wherein a bubble structure 2 is arranged in the rubber ball body 1 so that the density of the rubber ball body 1 is less than 0.845g/cm3。
Example 2
Based on the structure of the above embodiment, the present embodiment optimizes the structure thereof.
Specifically, the surface of the rubber sphere 1 has no bubble structure, i.e. the surface is smooth, and when foaming and vulcanizing are carried out, the smooth surface of the rubber sphere can be naturally formed by utilizing the blocking effect of the surface of the mold cavity on the flowing of elastic fluid.
The selection of the pore diameter of the bubbles can be realized by selecting different foaming agents and controlling the consumption of the foaming agents. Preferably, the bubble structure 2 in the rubber sphere 1 is uniform. The rubber ball body with the bubble structure inside can be formed by foaming vulcanization and foaming injection molding technology, and the uniformity of the bubble structure can be controlled by controlling the uniformity of the foaming agent and the uniformity of the stress. Preferably, the density of the rubber sphere 1 is 0.84g/cm or less3。
