摘要
在塔河油田碳酸盐岩裂缝性储层中,采用声波全波列测井及偶极横波测井来获取丰富信息,主要成分波有纵波、横波、斯通利波,主要采用时域和频域2种信息提取方法,来获得声波时差、频率和能量信息.其能量衰减和能量值的大小可以反映地层渗透性能,斯通利波能量的相对变化可用来定性划分渗透层,反射波能量反映渗透性地层的裂缝分布,为划分渗透层提供了良好的条件.
By using full wave acoustic, including longitudinal wave, transverse wave and stoneley wave and DSI log, we can get more information about fractures and cracks in carbonate reservoirs in Tahe Oilfield. Acoustic time difference, frequency and energy are collected by picking-up two kinds of information in time and frequency field. The energy and attenuation of the waves can be used to infer the permeability of a stratum. The relative changes of the energy of Stoneley wave can be used to define permeable strata.
