Abstract
The present invention discloses a method for proppant suspension and suspension parameter optimization based on bubble bridge effect, comprising: select a proppant and hydrophobically modify its surface to obtain a hydrophobically surface-modified proppant; prepare a bubbly fracturing base fluid; make the first optimization of the base fluids according to the average radius of the proppant and the average radius of the bubbles of the base fluids; optimally select the base fluids selected for the second time according to the interaction energy between the proppant particle and the bubble after the hydrophobically surface-modified proppant mixed with the base fluid; the basic parameters of the bubbly fracturing base fluid selected at the third time were used for the perfect selection for proppant suspension. The present invention establishes a procedure on experimental evaluation and parameter calculation optimization by suspending fracturing proppant with the bubble bridge effect on the hydrophobic surface.
