Core Plate Models for Experimental Study of Seepage Flow Patterns in Poor and Thin Reservoirs

Resumo

We propose an artificial core plate model for studying seepage flow patterns in fractured poor and thin reservoirs. We have analyzed the pressure gradient distribution, mapped sections with different seepage flow patterns, and studied the qualitative and quantitative parameters of the seepage flow patterns for liquid in thin and poor reservoirs. The experiments have shown that the seepage flow pattern in thin and poor reservoirs depends on the permeability and heterogeneity of the rock and the presence of cracks. The presence of cracks can compensate for the negative impact of low permeability and heterogeneity of the rock. From the experimental results, we can identify three sections in the rock with different seepage flow patterns. Fracturing can significantly reduce the size of the no-flow section (by at least 72%) and can increase the size of the quasilinear seepage flow section (by at least 86%).
