Numerical Simulation of High Frequency Vibration Recovery Enhancement Technology in Low-Permeability Reservoirs

摘要

The purpose of this article is to make a quantitative research on high frequency vibration recovery's advantages over traditional production methods. In this paper, acoustic pressure relation equation was established and a quantitative description about the porous media reservoir and fluid parameters alteration after high frequency vibration effect were attained. Furthermore, a preliminary mathematical model and computer modeling under high frequency vibration effect in low permeability reservoir were developed. This study was successfully applied to simulation of high frequency vibration recovery in a low permeability reservoir in Western China. The result showed that high frequency vibration recovery could stimulate single well production. By comparing with the well actual production history, it shows that this study can accurately simulate production performance of high frequency vibration recovery enhancement technology in low-permeability reservoirs.
