preparation example Construction

[0032]The preparation device of the rubber wax ball with wax inhibitor includes the following three parts:

[0033]Such asfigure 1 As shown, the first part is a rubber cleaning ball perforating device 10, which includes a perforating housing 11, a motor 12, a gear linkage device, a drill bit fixing plate 13, and a plurality of drill bits 14. The gear linkage device and the drill bit fixing plate 13 are arranged in the hole Inside the housing 11. The gear linkage device includes a plurality of gears, one of which is mounted on the output shaft of the motor 12, and the other gears are mounted on one end of each drill bit 14 one by one. The other end of each drill bit 14 passes through the drill bit fixing plate 13 and then extends out to punch holes. Housing 11; each drill bit 14 is mounted on the drill bit fixing plate 13 through a bearing and a bearing seat. The motor 12 provides power to the drill bit 14 through a gear linkage device. When the motor 12 is working, the output shaft of ...

Embodiment 1

[0040]Install 4 drill bits 14 with a diameter of 2mm, a length of 2cm and 8 drills with a length of 1.7cm on the drill fixing plate 13 in a square arrangement. The spacing between the drills 14 is 3mm, and the four 2cm drills are arranged in a square in the middle. Eight 1.7cm drill bits are arranged in a square on the outside, and the motor 12 is used to drive the gear to make the drill bit 14 move, and two sets of drilling holes are drilled on the two adjacent surfaces of the rubber ball, such as the front and the left side. The injection needle 32 of the same size as the drill bit is installed on the injection housing 31 one by one according to the arrangement of the drill bit 14, and the injection housing 31 and the injection pump 33 are connected together. Dissolve 70% sodium stearate, 15% sodium citrate and 15% sodium bicarbonate with absolute ethanol as a wax inhibitor slurry.

[0041]Such asFigure 4 As shown, during operation, put the ordinary rubber wax removal ball into the r...

Abstract

The present invention provides a rubber wax removal ball loaded with anti-wax agent and its preparation method, preparation device and application. The device is composed of a punching device, an injection device and a supporting device. The three devices are used together. The punching device can be used in traditional Holes are drilled on the surface of the rubber wax removal ball, and the injection device injects the anti-wax agent into the hole of the rubber wax removal ball. The support device plays the role of fixing and supporting the punching device and the injection device, and can be completed with the punching device and the injection device. Through a series of operations, the prepared rubber wax removal ball has dual functions of physical wax removal and chemical wax removal, and can be recycled and reused.

Description

Technical field[0001]The invention belongs to the field of crude oil transportation, and relates to a rubber wax removing ball carrying a wax inhibitor and a preparation method, a preparation device and an application thereof.Background technique[0002]Most of the crude oil produced in the oil field is waxy crude oil. Paraffin wax usually exists in the oil layer in a dissolved state. During the oil field production process, due to the decrease of temperature and pressure, and the escape of light components, the paraffin wax in the crude oil will gradually separate out. Crystal particles begin to precipitate in the oil flow or on the pipe wall, resulting in paraffin accumulation, reducing the cross-sectional area of ​​the pipeline, increasing the flow resistance of crude oil, affecting the efficiency of the oil pump, and when waxing is severe, the oil well pipeline can be completely blocked, resulting in shutdown.[0003]The wax control technologies for oil field gathering pipelines mai...
