Abstract

The invention relates to a polymer agitating device. The invention is characterized in that the device comprises an agitating tank, a cylindrical bracket and a pedestal, wherein the agitating tank is vertically and fixedly arranged in the cylindrical bracket, and the bracket is fixedly arranged on the pedestal; the cross section of the agitating tank is 8-shaped, and has a feeding port at the upper part thereof and a discharging port on bottom part thereof; a pair of spindle agitators are axially arranged in the agitating tank and comprise two main shafts axially running through the agitating tank, wherein upper ends and lower ends of the two main shafts are fixed with the agitating tank through bearings respectively; the lower ends of the two main shafts are respectively arranged with gears which are connected to the output end of a motor through a gear transmission device; a plural groups of blades are radially arranged on parts with different height of the two main shafts, and the blades on the two main shafts are arranged staggerly on height. The polymer agitating device has a compact structure, reduces volume of equipment, saves space and can be widely applied to driving polymer in offshore oil exploitation.

Description

technical field [0001] The invention relates to a polymer stirring device, in particular to a polymer stirring device used for dissolving polymers in petroleum development and production. Background technique [0002] In oil development and production, polymer flooding is an important technology for enhancing oil recovery. This technology dissolves water-soluble polymer solid dry powder evenly and injects it into the oil layer to drive oil, so as to achieve the ultimate goal of improving oil recovery and oil field production. Purpose. Among them, the dispersion and dissolution of the polymer is a key step. The general process of dispersing and dissolving is: the solid powder passes through the water-powder mixing device, and after being fully contacted with water, it is pumped to the dissolving tank for mixing, and then transported to the aging tank to swell and dissolve to form mother liquor, and then mixed with high-pressure injection water, The solution is diluted to th...
