Research of a modified nano-depressure and augmented injection agent

In this paper, the research and application of nanomaterials in oilfield chemical engineering was briefly described with emphasis on nano-silica enhanced oil recovery, depressure augmented injection. A study modification carried out indoors, a modified nano-depressure injection agent prepared by using coupling for surface grafting modification, followed introducing functional monomers in-situ modification. The effects silica dosage, dispersant regulator ratio, time product were investigated. It analyzed infrared spectroscopy, thermogravimetric analysis, nanoparticle size analyzer, transmission electron microscope, atomic force etc. series experiments conducted to evaluate temperature salt resistance, wettability, as well performance products.
