Bipolar polymer swelling particle dissolution accelerating device with water seepage structure

Abstract

The invention discloses a bipolar polymer swelling particle dissolution accelerating device with a water seepage structure. The device is characterized by consisting of a stretching unit and a liquid storage cavity, wherein the stretching unit comprises an upper fixed fluted disc, a movable fluted disc and a lower fixed fluted disc, which are all provided with a plurality of through holes, from top to bottom successively; the upper fixed fluted disc and the lower fixed fluted disc are fixed on the liquid storage cavity; the surfaces, close to the movable fluted disc, of the upper and lower fixed fluted discs are respectively of a short tooth structure, and are in uniform engagement with short tooth structures on the two surfaces of the movable fluted disc; the upper fixed fluted disc and the lower fixed fluted disc are internally provided with a plurality of water seepage channels which are communicated with a plurality of nozzles on the short tooth structures and are connected with an external water pipe; and the stretching unit also comprises a transmission shaft and a bearing seat, and the transmission shaft is connected with a belt pulley through the bearing seat and the liquid storage cavity. The device is simple to mount, small in floor space, light in weight and high in handling capacity, and can enhance the contact between injected water and polymer swelling particles, achieve forced water seepage handling ability, improve the efficiency and accelerate polymer dissolution.

Description

technical field [0001] The invention provides a forced stretching instant dissolving device for accelerating partial hydrolysis of polyacrylamide polymers, in particular to a device for accelerating polymer swelling particle dissolution with a bipolar water seepage structure. Background technique [0002] Polymer flooding, as one of the important methods to enhance oil recovery in oilfield development, has been widely used in onshore oilfields at home and abroad. Due to the lack of fresh water resources in offshore oilfields, the injected water has high salinity and high content of calcium and magnesium ions. Traditional partially hydrolyzed polyacrylamide has insufficient salt resistance and low viscosity, which is far from meeting the requirements of offshore oil fields. Due to the small number of hydrophobic groups on the main chain of the hydrophobic association polymer, the solution has the characteristics of a reversible three-dimensional network structure, good shear...

Problems solved by technology

However, due to repeated cutting of the polymer molecular chain, the chain is broken, and the solution viscosity is reduced; at the same time, the swollen particles block the screen or the orifice plate, which cannot meet the requirements of polymer dispensing on offshore platforms.
