摘要
Based on the theory of two-phase media and using ABV hydrocarbon detection technology,this paper analyzes the phenomenon of low-frequency resonance and high-frequency actuation for oil and gas in reservoir.Among them,the gas actuation is obvious and oil resonance is obvious.It also compares all kinds of time-frequency analysis method and employs generalized S transform time-frequency analysis method to get high-precision time-frequency spectrum.And a method of highlighting low-frequency resonance spectrum features caused by hydrocarbon is presented,that is recording the abnormal low-frequency energy of spectral characteristics away from the normal frequency.Using this technolog,the data volume of ABV hydrocarbon detection can be gotten.In application of the method to predict the oil-bearing ability of Fuyu reservoir in Gaotaizi area of Daqing placanticline,a good effect has been obtained.
