A Quantitative Measurement Method for Interlayer Channeling Flux of Heterogeneous Core Model

[0061] The heterogeneous model consists of three interconnected anti-rhythm sandstone models of equal thickness. Two sets of anti-rhythm experiments have been carried out. The core models used in the experiments are outcrop cores at the same place, and the wettability is strong water-wet. The basic data of the core are shown in Table 1. The oil used in the experiment is white oil, and the viscosity of the simulated oil at room temperature (25°C) is 12cp; the brine used in the experiment is NaBrCT enhancer with a salinity of 50000ppm. Both oil and water were evacuated and filtered before the experiment.
