| 摘 要： | 低频异常增强（ABV）油气检测技术在双相介质理论基础上,能够分析储集层中油、气的＂低频共振,高频衰减＂现象,其中气的＂衰减＂现象明显,而油的＂共振＂现象明显。通过对比各种时频分析方法,选用广义S变换时频分析方法得到高精度的时频谱,使用突出地层含油引起的低频共振频谱特征的方法,记录频谱特征中远离正常频率规律的异常低频能量,得到ABV检测数据体。将此技术应用于大庆长垣高台子地区扶余油层,能快速预测储层的含油性,不受井约束,取得了良好的效果。

| Abstract: | 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. |
