Artificially resonant wave strengthened oil displacement dynamic simulation experimental device and experimental method

Abstract

The invention discloses an artificially resonant wave strengthened oil displacement dynamic simulation experimental device and an experimental method. The experimental device comprises an artificially resonant wave test bed, core grippers fixed on the artificially resonant wave test bed, thermotanks distributed outside the core grippers, an intermediate transitional water-delivery container, an intermediate transitional oil delivery container, a water storage tank, an oil storage tank, and liquid containers connected with liquid outlets of the core grippers. The experimental device comprises the following steps of: 1, performing an unartificially resonant wave dynamic simulation experiment; 2, replacing cores and performing an artificially resonant wave dynamic simulation experiment on the plurality of cores under the artificially resonant wave vibration conditions of different frequency and identical vibration acceleration; and 3, performing data processing. The device and the methodensure rational design, convenience of distribution, use and operation, perfect functions and good simulation effect; and the single-phase and two-phase seepage characteristics of the cores, the saturation of residual oil and the final oil recovery factor can be tested under the conditions of artificially resonance waves and different displacing mediums.

Description

technical field [0001] The invention belongs to the technical field of dynamic physical simulation experiment of enhanced oil displacement in an oil production chamber, and in particular relates to a dynamic simulation experiment device and method for artificial resonance wave enhanced oil displacement. Background technique [0002] As one of the most important physical enhanced oil recovery technologies, the artificial resonance wave enhanced oil recovery technology achieves the purpose of increasing production and injection and improving oil recovery by using the excitation effect of high-power artificial wave field on oil layers. The research and application of artificial resonance wave oil recovery technology at home and abroad has progressed rapidly, and some related supporting equipment and technology have been formed, and correspondingly achieved a certain effect of mine production increase. But in general, artificial resonance wave enhanced oil recovery technology is...

AI Technical Summary

Problems solved by technology

But in general, artificial resonance wave enhanced oil recovery technology is basically still at the level of single field test, so it is difficult to form a large-scale promotion and application. There are deficiencies in conditions and construction, especially the lack of high-precision and high-stability indoor simulation experimental conditions, devices and effective experimental methods
