Embodiment 1

[0026] This embodiment provides a smart ball for wax removal in gathering and transportation pipelines, combined with figure 1 and figure 2 As shown, it includes a spherical body 1, and the spherical body 1 has a built-in vibration device 2. The vibration device 2 is electrically connected to a controller 3, and the controller 3 controls the start and stop of the vibration device 2. The vibration device 2 and the controller 3 are both Connect the battery 4.

[0027] The shape and size of the wax-removing smart ball for gathering and transportation pipelines in this embodiment are basically the same as those of conventional balls, but a vibrating device 2 is installed inside. Forced to stay, when it reaches a certain (t) time, controlled by the controller 3, it can vibrate up and down by itself, and the heat generated by the vibration and vibration will loosen or melt the wax block to achieve the effect of clearing and preventing wax.

Embodiment 2

[0029] This embodiment is further improved on the basis of Embodiment 1. In this embodiment, the interior of the spherical body 1 is a non-solid structure, and the center of the spherical body 1 is a spherical vibration sleeve 5. The vibration device 2, controller 3 and The batteries 4 are all placed in the spherical vibrating sleeve 5 , and the outer wall of the spherical vibrating sleeve 5 is connected to the inner wall of the spherical body 1 by connecting columns 6 .

[0030] A wax remover 7 is provided in the annular space between the outer wall of the spherical vibrating sleeve 5 and the inner wall of the spherical body 1 , and a wax remover outlet 8 is provided on the spherical body 1 . An electric valve is arranged at the outlet 8 of the wax remover, and the electric valve is electrically connected to and controlled by the controller 3 to open and close.

[0031] If this kind of smart ball encounters wax blockage when running in the pipeline, it is forced to stay. When...

Embodiment 3

[0033] This embodiment further elaborates on the vibrating device 2 in the above two embodiments. The vibrating device 2 is composed of a cylindrical motor and an eccentric block. The cylindrical motor is electrically connected to the controller 3. The eccentric block is mounted on the output On the shaft, the eccentric block is semi-cylindrical or pie-shaped.

[0034] The controller 3 controls the start of the cylindrical motor, and the eccentric block on the cylindrical motor rotates under the action of the cylindrical motor to generate eccentric force and then vibration.

[0035] In the implementation process of the above two embodiments, there is a premise that if the smart ball encounters wax blockage when running in the pipeline, it will be forced to stay. Therefore, there must first be a device for detecting the "detained" state. A wireless locator 9 is installed inside the spherical body 1 , and the wireless locator 9 is electrically connected to the controller 3 . Th...

Abstract

The invention belongs to the field of oil gathering pipeline wax removal, and in particular relates to a gathering and transportation pipeline wax-removing intelligent ball and a wax-removing method, which are mainly applied to an automatic ball throwing device. The gathering and transportation pipeline wax-removing intelligent ball provided by the invention can automatically vibrate up and down when being blocked by wax to be detained under compulsion, and wax blocks are loosened or melted through vibration and heat generated by vibration, so that the wax removing and preventing effect is achieved; and the intelligent ball can spray a certain dose of wax-removing agent during vibration, so that the intelligent ball can directly reach to the blocking position through two approaches, the effective wax removing and preventing effect is achieved, and waste of the agent caused by the fact that the wax removing agent is added at the mouth of a well is avoided.

Description

technical field [0001] The invention belongs to the field of wax removal for oil collection pipelines, and in particular relates to a smart ball for wax removal in oil collection pipelines and a wax removal method thereof, which are mainly used in automatic ball throwing devices. Background technique [0002] Research has found that crude oil in my country's oilfields is rich in wax. According to statistics, crude oil containing more than 10% wax accounts for more than 90% of the total output of crude oil. 50%, such a high wax content ratio causes the wax in the crude oil to condense in the pipeline for transporting crude oil, thus causing blockage of the crude oil pipeline, and there are certain safety hazards. Therefore, it is necessary to adopt a suitable wax removal method to realize the wax removal of crude oil Operation. [0003] At present, there are two common wax removal methods for oil gathering pipelines: physical wax removal and chemical wax removal. The physical...
