Centrealoil-- Polymer in-depth profile controlling agent
Product introduction:
The product is used for microfracture profile of water well distant end injection and high permeable formation plugging.
The product is composed of a variety of modified starch, has a good delay gel, adsorption, porous medium shear resistance, good pump performance. After gelation, the gel absorbs water and swell, oleophobic and hydrophilic. It has a good selective effect of water plugging but oil phase.
The main technical index:
①Gel time:≥72h
②Gel strength(1.5S-1):≥5000mPa·s
③The plugging rate of water shutoff :≥80%
