AB  - Many chemicalprofile agents have been widely adopted to control water content. Polymermicrosphere is a new potential profile control technology developed rapidly inrecent years. According to the diameter of reservoir rock throat, the polymermicrospheres matching the throat diameter are prepared by nano-micron materialsynthesis method. The mechanism of profile control is that the microspheres canmove freely in the porous media after entering the reservoir with injectedwater. The polymer microspheres accumulate in the throat to block up and causeresistance to the flow, so that the subsequent flow will turn around and flowaround. Because the microspheres have the certain degree of viscoelasticity,the microspheres will be elastic deformation as the plugging pressuredifference increases to a certain extent. Then the polymer microspherescontinue to migrate deeply through the throat, so as to achieve step-by-stepdeep profile control and flooding.In this article, divinylbenzene-co-acrylamide microspheres (DCAMs) with differentparticle size were firstly prepared by using dispersion polymerization. Thentheir physical properties such as chemical structure, micromorphology, particlesize and size distribution, swelling property and stability were reseached. Thecore displacement experiment under the simulated reservoir conditions was designedto analyze the recovery and profile modification performance of DCAMs.
