Abstract

The seepage equation of formation fluid under the effect of pulse wave is established according to the dynamic mechanism of the pulse wave propagation in the formation and the wave mechanics theory.The flow velocity equation of formation fluid is obtained under the hypothesis that the flow velocity of formation fluid under the effect of pulse wave is the stack of the flow velocity of formation fluid without the effect of pulse wave with the vibration velocity of fluid particle under the effect of n-th pulse wave.The influences of the distance from pulse source,time,pulse frequency and pulse amplitude on the seepage velocity of formation fluid are analyzed by an example.It is shown that,the amplitude of the seepage velocity decreases with the increase of the distance;the amplitude of the seepage velocity decreases firstly and then increases with the increase of the pulse frequency;the amplitude of the seepage velocity increases with the increase of the amplitude.The research results can provide theoretical basis for the field application of pulse wave recovery technology.
