摘要： The invention is directed to stable and labile crosslinked water swellable polymeric microparticles that can be further gelled, methods for making same, and their various uses in the hygiene and medical arts, gel electrophoresis, packaging, agriculture, the cable industry, information technology, in the food industry, papermaking, use as flocculation aids, and the like. More particularly, the invention relates to a composition comprising expandable polymeric microparticles having labile crosslinkers and stable crosslinkers, said microparticle mixed with a fluid and an unreacted tertiary crosslinker comprising PEI or other polyamine based tertiary crosslinker that is capable of further crosslinking the microparticle on degradation of the labile crosslinker and swelling of the particle, so as to form a stable gel. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric microparticles are injected into a well and when the heat and/or pH of the well cause degradation of the labile crosslinker and when the microparticle expands, the tertiary crosslinker crosslinks the polymer to form a stable gel, thus diverting water to lower permeability regions and improving oil recovery.

摘要： The invention is directed to stable crosslinked swellable fluorescently tagged polymeric microparticles, methods for making same, and their various uses. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric particles are injected into target zone and when the heat and/or suitable pH of the target zone cause degradation of the labile crosslinker and the microparticles expand. The swelled polymer diverts water to lower permeability regions and improves oil recovery. The tags allow monitoring of the presence and concentration of the tagged microparticles and ultimately allow evaluation of the performance of such treatments. Detection of polymeric microparticles in producing wells can be instructive for teaching about the character and extent of thief zones in the subsurface. Better knowledge of the reservoir flow will enable improved application of the gel treatments, improved oil recovery, and allow improved forecasting using simulation modeling.
