Abstract
The invention relates to processing technology of underground reservoir area, in particular to a processing system of down-hole low frequency acoustic wave. The processing system of down-hole low frequency acoustic wave comprises a wellhead adjustment device, a down-hole low frequency generator, a transmission device of connecting wellhead adjustable device and a down-hole low frequency generator. The transmission device comprises a three-structure wellhead which comprises a vertical two-opening pipe and a horizontal branch pipe located in the middle of the vertical two-opening pipe, An underwater acoustic transducer is arranged on an inlet of the horizontal branch pipe, and connected with the down-hole low frequency generator through an audio transmission line. The wellhead adjusting device comprises a regulator of adjusting frequency and a viscosity reducer storage unit. The regulator of adjusting frequency is used for sending the adjustable signal to the down-hole low frequency generator through the underwater acoustic transducer so that the vibration frequency of the down-hole low frequency generator achieves the resonant frequency of the oil layer. The viscosity reducer storage unit is used to release a viscosity reducer, which improves oil recovery efficiency by adjusting the regulator of adjustable frequency and the viscosity reducer storage unit.
