Problems solved by technology

This type of polymer has the characteristics of temperature resistance, salt resistance, alkali resistance, high viscosity, and high shear resistance, so it has broad application prospects, but its dissolution problem has always been one of the technical problems restricting the industrial application of this type of polymer.
However, there are problems that the dissolution time is long, requiring more than 2 hours, or incomplete aging to form gel-like insoluble matter and uneven mixing of the solution, which affects the oil displacement effect and thus affects the oil displacement efficiency.

Embodiment Construction

[0013] Such as figure 1 As shown, the stirring device for rapidly dissolving hydrophobic associating polymers of the present invention still includes a driving device 1, a stirring transmission reduction mechanism 2, a stirring shaft 4, and a stirring paddle 5 installed on the stirring shaft 4, a stirring shaft 4 and a stirring paddle 5. Insert into the mixing tank 8. Among them, the stirring blade 5 is a push-up wide blade axial flow blade. According to the height of the mixing tank 8, 1 to 3 push-up wide-blade axial flow paddles can be installed on the mixing shaft 4. The stirring shaft 4 and the push-up wide-blade axial flow paddle can be made of stainless steel or carbon steel lined rubber material. The push-up wide-blade axial flow paddle is composed of a hub 6 and 3 or 4 blades 7, such as figure 2 , 3 As shown, the push-up wide-blade axial flow paddle in this specific embodiment is provided with three blades 7, which are evenly distributed and fixed on the hub 6 along th...

Abstract

The invention relates to a device for dissolving, curing and stirring hydrophobic associating polymer, comprising a driving device, a stirring and driving decelerating mechanism, a stirring shaft anda stirring paddle arranged on the stirring shaft. The device is characterized in that the stirring paddle is a push-up type wide blade axial flow paddle. By adopting the push-up type wide blade axialflow stirring device, the device can obviously improve axial circular flow, evenly and uniformly dissolves the polymer, and can keep higher viscosity coefficient, thereby accelerating the dissolving and the curing of the polymer and being capable of greatly improving the oil displacement efficiency of the polymer.

Description

Technical field [0001] The invention belongs to the technical field of petroleum extraction equipment, and specifically is a stirring device used in a water-repellent associative polymer dissolution and maturation tank in a polymer flooding process. Background technique [0002] Polymer flooding, as one of the important means for oilfield development to stabilize or increase production, has been widely used in onshore oilfields at home and abroad. Major oil regions such as Daqing, Shengli and Karamay in my country have conducted field tests and achieved great success. In particular, Daqing Oilfield has entered the stage of large-scale industrial application. On the basis of 42% waterflooding recovery rate, the recovery rate after the implementation of polymer flooding has been increased by 12%, bringing the final recovery rate to 55%. [0003] Hydrophobic associative polymers are widely used in tertiary oil recovery, drilling fluids, completion fluids and oilfield profile control ...
