Hydraulic fracturing is a pivotal technology in the development of unconventional tight reservoirs, which accurate monitoring fracture parameters significant. This paper proposes an improved differential evolution algorithm (EMDE) to calculate Effective Propped Volume (EPV) accurately. The forward simulation results demonstrate that when transmitting source plane particular position, relationship between signals and specific parameter most obvious, providing basis for application inversion algorithms. Furthermore, difference population center individual added accelerate convergence EMDE algorithm. A simplified selection strategy simulated annealing used enhance speed ability find global optimal value objective function simultaneously. one-stage two-stages strategies are designed parameters. In two-stage inversion, second-stage constrained by first-stage results. It indicates errors can be controlled within 5%. Through proposed this paper, feasibility electromagnetic method monitor EPV verified, it provides theoretical guidance subsequent construction adjustments.
