Embodiment 1

[0030] Such as figure 1 As shown, a kind of polymer supermass transfer deepening instant dissolving device of the present invention comprises housing 3, the end cover 2 that is connected on described housing 3 by bolts, motor 10 and is arranged in described housing 3 The mass transfer tray 4, the mass transfer ring 7, and the tray cover 6 on the mass transfer tray 4 are connected by bolts; the motor 10 is axially installed on the housing 3;

[0031] Such as Figure 4 and 5 As shown, the mass transfer tray 4 has a connecting portion connected to the motor 10, and an annular slot A16 matching the mass transfer ring 7;

[0032] Such as Figure 6 and 7 As shown, the tray cover plate 6 is axially provided with a through hole for penetrating the liquid pipe 1, and is used for inserting the ring-shaped slot B19 of the mass transfer ring 7;

[0033] The mass transfer tray 4 is connected to the rotating shaft of the motor 10; the annular engaging groove A16 and the annular engagin...

Embodiment 2

[0039] Such as Figure 8 As shown, a polymer super mass transfer deepening instant dissolving device of the present invention is also equipped with a cleaner 17 on the basis of Embodiment 1, wherein the cleaner 17 is installed into the liquid inlet pipe 1 and extends into the mass transfer tray 4 on one end.

[0040] In the second embodiment, if Figure 9 and 10 As shown, the cleaner 17 is a cross-shaped impeller, the impeller is four L-shaped blades 18, the L-shaped blades 18 are perpendicular to the mass transfer ring 7, this design can better clean the mass transfer ring 7 The polymer swelling particles on the surface, the distance between the cleaner 17 and the mass transfer ring 7 is determined according to the particle diameter of the polymer swelling particles.

[0041]When this embodiment is in use: the liquid inlet pipe 1 is connected with the outlet of the on-site liquid transfer screw pump, and the liquid outlet 8 is connected with the inlet of the aging tank. T...

Abstract

The invention discloses a polymer ultra-strong mass transfer deepening instant dissolving device. The polymer ultra-strong mass transfer deepening instant dissolving device comprises a shell, an end cover covering the shell, a motor, a mass transfer tray arranged in the shell, a mass transfer ring and a tray cover plate covering the mass transfer tray, the motor is axially mounted on the shell, and the mass transfer tray is connected with a rotating shaft of the motor; the mass transfer tray and the tray cover plate are respectively provided with a ring-shaped clamping groove A and a ring-shaped clamping groove B which are opposite to each other; two ends of the mass transfer ring are respectively embedded into the ring-shaped clamping groove A and the ring-shaped clamping groove B; a liquid outlet is formed in the side face of the shell, a liquid inlet pipe is arranged on the end cover in the axial direction, one end of the liquid inlet pipe is located outside the end cover, and the other end of the liquid inlet pipe penetrates through the tray cover plate and extends into the mass transfer tray. According to the method, a uniform polymer solution can be obtained in a short time,the polymer ultra-strong mass transfer deepening instant dissolving device can be used in the offshore platform polymer oil displacement technology, the oil recovery efficiency is improved, and the polymer ultra-strong mass transfer deepening instant dissolving device further has the advantages of being easy to install, large in handling capacity, light in weight and small in occupied area.

Description

technical field [0001] The invention relates to a polymer super-strong mass transfer deepening instant dissolving device, which belongs to the technical field of petroleum engineering. Background technique [0002] Efficient polymer dispensing is the key to implementing polymer flooding in offshore oilfields, but offshore platforms pose severe challenges to polymer dispensing systems. [0003] First of all, offshore platforms have small space and limited carrying capacity. The offshore platform integrates production, transportation, power, and living functions, with high space utilization and high equipment density. The transportation, hoisting, installation, and maintenance of large equipment are limited, and the space available for polymer dispensing equipment is very limited. At the same time The limitation of the overall carrying capacity of the platform should also be considered. Therefore, the polymer dispensing device is required to be small in size and light in weig...
