Abstract:
Disclosed is a method for simulation of a microscopic flow of pre-crosslinked gel suspension liquid in a porous medium, including the steps of: establishing a simulation area of the porous medium based on a two-dimensional core CT slice image and subjecting the simulation area to numerical grid discretization; setting initial position and original shape of pre-crosslinked gel particles to generate virtual boundary mark points; marking the type of numeric grid nodes; calculating the force of the fluid on each virtual boundary mark point according to the momentum change of the numerical grid nodes on the boundary of the pre-crosslinked gel particles; calculating the contact force on each virtual boundary mark point using a particle contact action model; calculating the bending recovery force and the stretching recovery force for each virtual boundary mark point based on the current shape and original shape of the pre-crosslinked gel particles; and calculating the velocity and displacement of each virtual boundary mark point based on Newton's second law, wherein the respective virtual boundary mark points are connected to obtain the overall shape and position of the pre-crosslinked gel particles.

Claim (Index 3):
The method for simulation of a microscopic flow of pre-crosslinked gel suspension liquid in a porous medium according to  claim 1 , wherein that in the step (3), the type for the numeric grid node is determined as follows: if the numerical grid node and its neighboring 8 nodes are covered by pre-crosslinked gel particle, then it is marked as the intra-particle node; if the numerical grid node is covered by the pre-crosslinked gel particle but there is uncovered neighbor node, then it is marked as the particle boundary node; if the numerical grid node and its neighboring 8 nodes are not covered by the pre-crosslinked gel particle, then it is marked as the intra-fluid node; if the numerical grid node is not covered by the pre-crosslinked gel particle but there is covered neighbor node, then it is marked as the fluid boundary node.
