The invention relates to a high-concentration mother liquor diluting mixing and relative molecular mass control device. The high-concentration mother liquor diluting mixing and relative molecular masscontrol device comprises an upper shell and a lower shell. An upper transition joint is welded to the upper end of the upper shell. A screw rod seat is welded to the lower end of the upper shell. Thelower shell is welded to the side, close to one end of the screw rod seat, of the upper shell. A sealing plug is welded to the upper end of the lower shell. A lower transition joint is welded to thelower end of the lower shell. The upper shell communicates with the lower shell. A control diameter sleeve is adjusted through an adjusting mechanism and moves up and down in the upper shell. A lowerpositive and negative mixing and proportioning pipe is mounted in the lower shell. The lower positive and negative mixing pipe is close to the lower transition joint. The device can achieve controlling over the relative molecular mass of a single well solution, a personalized service measure is provided for oil field polymer flooding and three compound combination flooding oil recovery, so that the oil layer permeability of each injection well and the relative molecular mass of the injected solution are controlled to be more matched, and the oil displacement effect is further improved.
Description
technical field [0001] The invention relates to a novel multi-functional high-concentration mother liquid dilution mixing and relative molecular mass control device in a surface injection process of oilfield polymer flooding and three-element compound flooding. Background technique [0002] At present, oilfield polymer flooding and ASP flooding injection systems use the polymer to prepare high-concentration mother liquor, then pass through the filter device, pump the mother liquor into the water pipeline, dilute it according to a certain ratio, and pass it through the static mixing device After mixing, it is injected into the oil layer through the injection well. [0003] For different development blocks, due to the influence of plane contradiction, some injection wells have different permeability to a certain extent, and not all injection wells are suitable for solutions with the same relative molecular mass. This difference will cause some oil layers with relatively low p...
