THE STABILITY ANALYSIS MODELS OF PROPPANT PACKING FOR HYDRAULICALLY FORMED HORIZONTAL FRACTURE

  • Assuming an evenly-packed pattern of the proppant in thehydraulic cracks of the perforating well, considering the intensity ofproppant packing, parameters of reservoir characteristics, the fluidparameters, well production condition and fluid flow in the fracture, amechanical model of stability and fluid flow models in porous medium forproppant packing formation are proposed by considering the action offormation stress and additional stress produced by fluid flow in the porousmedium. The application results show that the coincidence rates of the oilwells, sand free oil wells and sanding oil wells are, respectively,84.66\%, 84.18\% and 88.10\%, and the calculating precision of the models areverified. The presented models can provide guidances for sandcontrol measures in Daqing Oilfield.
