Abstract

The invention discloses a polymer mother liquor aging apparatus and a polymer mother liquor aging method, and belongs to the field of tertiary oil recovery. The apparatus comprises: an aging tank, stirrers, a skidded body, wherein the aging tank is placed on the skidded body, and comprises a plurality of liquid storage bins, the adjacent liquid storage bins are communicated by flow guide grooves,the inlet of the flow guide groove is positioned at the bottom portion of the previous liquid storage bin, the outlet of the flow guide groove is positioned at the top portion of the next liquid storage bin, the liquid storage bin positioned at the head portion is provided with a liquid inlet, the liquid storage bin positioned at the tail portion is provided with a liquid outlet, and the interiorsof each liquid storage bin are respectively provided with the one stirrer. According to the present invention, the aging tank is arranged on the skidded body, such that the occupation area is reduced, the moving is convenient, and the application range is broad; and the plurality of the liquid storage bins are communicated by the flow guide grooves so as to improve the aging effect.

Description

technical field [0001] The invention relates to the field of tertiary oil recovery, in particular to a polymer mother liquor aging device and method. Background technique [0002] Polymer flooding technology is an important technology in tertiary oil recovery. When using polymer flooding technology for oil displacement, it is necessary to inject polymer solution into the oil layer. In order to meet the use requirements of polymer flooding, it is necessary to dissolve the dry polymer powder in water to form a polymer mother liquor, and then mature the polymer mother liquor to obtain a polymer solution that meets the use requirements, avoiding fisheye phenomenon, and at the same time reduce polymer mechanical degradation. Therefore, it is necessary to provide a polymer mother liquor curing device. [0003] The prior art provides such a polymer mother liquor curing device: install a large-volume curing tank on a wide ground, and a mixer is installed in the tank of the curing ...
