Study of Characterization Methods on the Particle Size of SMG

Abstract:

Soft moveable gel (SMG) is a new kind of deep profile control microgels used in many oilfields. SMG has many advantages of high temperature, salt tolerance, shear resistance, controllable grain size, good control and oil displacement effect. The SMG deep profile control technique can remarkably improve oil recovery of the high temperature and high salinity oilfields. While the successful applications of SMG deep profile control technique are greatly decided by the size matching ability between SMG microgels micelle particles and reservoir pore throat. Therefore, three different experimental methods such as microscope, SEM analysis, and laser scattering method are used for particle characterization at first. Based on that, the new method utilizing near-infrared spectroscopy is innovated and developed. The method has the advantages of non-destructive measurement of original state, convenient, accurate and reliable results etc.. Finally, three levels of SMG particle size entitled by nanometer, micron, and sub-millimeter are systematically evaluated. The results show the sizes are 0.06, 21.37, about 39.24 μm respectively in the new method. Different particle size of SMG can be applied in deep profile control of high, medium or low permeability reservoirs correspondingly with high temperature and high salinity.
