Abstract

Summary

The present work is devoted to increasing the efficiency of development of an oil field by horizontal wells due to the effect on the productive layer of elastic vibrations. Based on the results of laboratory studies, the viscosity of oil and the increase in the permeability of the formation have been accepted as mechanisms of acoustic action on a saturated porous medium. The influence of the wave action on the oil production process is considered using a mathematical model of fluid inflow to a horizontal well, taking into account the features of filtration in conditions of inhomogeneity of the properties of the formation and fluids. It is shown that the frequency and amplitude of the oscillations are the main factors of increasing the production rate of a horizontal well. At low frequencies, the effect of increasing the flow rate is weak, and at frequencies above 2.5 kHz, the increase in the production rate of a horizontal well is practically proportional to the increase in frequency. The obtained modeling results are in quantitative agreement with the results of the field data.
