Movable dry stored powder dispersion module for polymer injection and oil production of offshore oil production platform

Abstract

The invention discloses a movable dry stored powder dispersion module for the polymer injection and oil production of an offshore oil production platform, which comprises a base, a tank body, vibrators, an electric knife gate valve, a bottom level meter, a feeder, a material receiving hopper and a dispersed mixing device; and the dispersion module is characterized in that the tank body is set into a vertical cylindrical shape, a cone radiating from the lower middle part of the center of the tank body to the tank wall of the upper middle part of the tank body divides the tank body into two sealed bodies, the upper part of the cone is an upper chamber, the lower part of the cone is a lower chamber, the middle parts of the left and right side walls of the cone are respectively provided with a vibrator, the upper middle part and lower part of the front and rear inside walls of the cone are respectively provided with a mirror, the lower part of the lower chamber is provided with the dispersed mixing device, and the circumferential side wall of the lower part of the cone is provided with the bottom level meter; the upper chamber and the lower chamber are provided with an air feeding tube communicated with a dehumidifier; and the tank wall of the lower middle part of the tank body is provided with an explosion-proof intelligent control box for controlling the operation of the dry powder storing and mixing module.

Description

technical field [0001] The invention relates to a mobile dry powder storage material dispersing module for polymer injection and oil production on an offshore oil production platform, which is suitable for a polymer injection and profile control oil production process on the marine oil production platform. Background technique [0002] At present, polymer injection flooding has been widely used in the tertiary oil recovery process of onshore oilfields. The dry powder dispersing part in the polymer injection device is mainly composed of a storage bin, a feeding tank and a dispersing and mixing device. The tertiary oil recovery process at sea has also been put on the agenda. For example, if the onshore polymer injection and dispersion device is directly moved to the offshore oil production platform, the device is scattered and covers a large area, which is extremely unsuitable for the narrow space of the marine oil production platform. In addition, the ocean atmosphere has a...

Problems solved by technology

If the onshore polymer injection and dispersing device is directly moved to the offshore oil production platform, the devices are scattered and occupy a large area, which is extremely unsuitable for the small space of the offshore oil production platform

Moreover, the ocean atmosphere contains a lot of moisture, so it is advisable to make the dry powder agglomerate; the platform above is an open-air environment, which cannot prevent wind and rain

Therefore, the land polymer injection dispersion device cannot be applied on the offshore platform
