| titleOfInvention | Screening method for applicability of nanoscale polymer microspheres in medium-high permeability oil reservoirs |
| abstract | A screening method for the applicability of nano-scale polymer microspheres in high-permeability oil reservoirs is characterized in that physicochemical property experiments are carried out on the polymer microspheres to obtain the expansion characteristic, the shear resistance and the agglomeration property; characterizing the average pore radius of a residual oil enrichment area of the stratum and the average pore radius of a high water-bearing area by a nuclear magnetic resonance technology, and screening out a suitable polymer microsphere type according to the average pore radius; screening out polymer microspheres meeting the standard retention rate by combining a physical simulation experiment with a retention rate calculation formula; the most suitable polymer microspheres are selected from economic indexes through a polymer microsphere deposition regulating reservoir seepage key parameter formula and a polymer microsphere injection volume formula, and the use is more accurate and practical. |
