CONTROLLED-SIZE MICROGEL PREPARATION METHOD |
摘要 |
FIELD: oil and gas production. ^ SUBSTANCE: method of preparing controlled-size microgels, which can be used in oil and gas wells to prevent water inflow, consists in introducing polymer and suitable crosslinking agent into porous and permeable medium. Passage and passage velocity of polymer and crosslinking agent are controlled such as to provide crosslinking of polymer to form microgel aggregates in porous and permeable medium and to control sizes of aggregates leaving this medium. Removed solution contains microgel aggregates essentially equal in size. ^ EFFECT: achieved effective size control microgel aggregates. ^ 11 cl
