Abstract
The hole in the shale formation is in nanometer or micrometer scale, so the conventional plugging materials which are in the scale of millimeter cannot be used during the drilling of the shale formation. An effective way to solve this problem is to develop new plugging materials, which are in the nanometer or micrometer scale. In this article, the micron copolymer particles were prepared by the soap-free emulsion polymerization of the monomers methyl methacrylate (MMA) and acrylamide (AM). The structure of the copolymer particles was characterized by the Fourier transform infrared spectroscope (FT-IR). The particle size was determined by dynamic light scattering (DLS). In addition, the salt tolerance, temperature resistance and compatible property of the particles with the additives of drilling fluids were studied in detail.
