| Polymer microspheres profile control technology, it is according to the characteristics of the reservoir pore diameter for micron level, with the synthetic mechanism and method of polymer materials, the synthesis and reservoir rock pore diameter matching organic polymer microparticles, and for deep displacement implementation improve waterflood recovery efficiency purpose a new technology. Is the average size of a few hundred nanometers, polymer microspheres can be evenly dispersed in water, easy to enter the water injection formation, then slowly swell gel microspheres. When microspheres with water injection reservoir, a large number of particles will be widely distributed in reservoir rocks in the pore, and the migration and plugging in the pores of the rock in the reservoir, deformation, migration and plugging, changing direction of injected fluid flow in reservoir rocks, effectively increase the sweep efficiency of injected water in reservoir, reach a deep displacement of improving the water injection development effect improve recovery factor. So the research of polymer microspheres deep areas of high water cut oil displacement technology development, production has the vital practical significance,effectively solve GanGuYi production plant water injection after water flooding development region growing oil well water, the water breakthrough and water injection the effect not beautiful, a precipitation increased, the effect of oil GanGuYi oilfield production stable and high efficiency to lay the solid foundation. Expects the technology research and application results of application can not only in the extension of the oilfield co., LTD., also can be application in other fields, has a good application foreground and good economic benefit. |
