preparation example Construction

[0032] The preparation device of the rubber wax-removing ball loaded with anti-wax agent comprises the following three parts:

[0033] Such as figure 1 As shown, the first part is a rubber wax removal ball punching device 10, including a punching housing 11, a motor 12, a gear linkage, a drill bit fixing plate 13 and a plurality of drill bits 14, and the gear linkage and the drill bit fixing plate 13 are arranged on the punching hole. Inside the shell 11. The gear linkage device includes a plurality of gears, one of which is installed on the output shaft of the motor 12, and the other gears are installed on one end of each drill bit 14 correspondingly, and the other end of each drill bit 14 passes through the drill bit fixing plate 13 and stretches out to punch a hole. Housing 11; each drill bit 14 is installed on the drill bit fixing plate 13 through bearings and bearing seats. The motor 12 provides power to the drill bit 14 through the gear linkage. When the motor 12 works...

Embodiment 1

[0040] The drill bits 14 with a diameter of 2mm, four lengths of 2cm and eight lengths of 1.7cm are installed on the drill bit fixing plate 13 according to a square arrangement, the spacing between the drill bits 14 is 3mm, and four 2cm drill bits are arranged in a square in the middle. 8 drill bits of 1.7cm are arranged in a square on the outside, drive the gear with the motor 12 to make the drill bit 14 move, and drill two groups of holes for example on the adjacent two surfaces of the rubber wax removal ball, such as the front and the left side. Injection needles 32 of the same size as the drill bits are mounted on the injection housing 31 one by one according to the arrangement of the drill bits 14 , and the injection housing 31 is connected with the injection pump 33 . Dissolving 70% of sodium stearate, 15% of sodium citrate and 15% of sodium bicarbonate in absolute ethanol is used as wax preventive agent slurry.

[0041] Such as Figure 4 As shown, during operation, the...

Description

technical field [0001] The invention belongs to the field of crude oil transportation, and relates to a rubber wax removing ball loaded with an anti-wax agent, a preparation method, a preparation device and application thereof. Background technique [0002] Most of the crude oil extracted from the oil field is waxy crude oil, and paraffin usually exists in a dissolved state in the oil layer. During the oil field production, due to the reduction of temperature and pressure, and the escape of light components, the paraffin in the crude oil will gradually precipitate 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 pipe, increasing the flow resistance of crude oil, and affecting the efficiency of the pump. [0003] The anti-wax technologies of oilfield gathering and transportation pipelines mainly include chemical anti-wax, hot washing wax removal, rubber ball wax remo...
