Abstract

Abstract: Tight oil is an unconventional petroleum resource, which occupies a essential position in the global energy structure. The main purpose of this paper is to quantitatively characterize the lower limit of the physical properties of tight oil reservoirs in nanomaterial porous media. This paper starts with the single-phase deionized water flow experiment in micro-nano-quartz tube, combined with the tight oil reservoir core single-phase simulation, formation water seepage experiment, analyzes and characterizes the low-velocity and nonlinear seepage characteristics of tight reservoir fluid. At the same time, combined with the dynamic network simulation technology, the process of water flooding in tight oil reservoirs under different conditions is simulated, and the influence of each influencing factor on the two-phase seepage of water flooding is determined. In addition, combined with different water injection capillary numbers, water flooding nuclear magnetic resonance experiments, the dynamic characteristics and distribution changes of oil and water, in two phases in the water flooding process are analyzed, and the simulation results are used for verification and analysis, to indicate the reasonable and efficient water flooding development of tight oil reservoirs.
