拟声波构建技术依据对储层敏感的非声波地球物理测井信息构建具有声波量纲的新曲线,即拟声波曲线,使之既能反映地层波阻抗和速度的变化,又能反映地层岩性的细微差别,可以较好地解决储层定量预测中的岩性识别难题。针对张东古潜山地层实测声波时差曲线对砂、泥岩的岩性反映不明显,无法进行储层反演预测的问题,采用了拟声波构建技术,将对储层岩性敏感性好的自然电位曲线转换成拟声波曲线,以此为约束条件实现了储层预测的目的,取得了较好的应用效果。 Pseudoacoustic wave construction technique builds a new curve with acoustic dimension based on non-acoustic geophysical well logging information that is sensitive to reservoir, that is, the pseudo-acoustic curve, which can not only reflect the change of formation wave impedance and velocity, but also reflect the lithology Which can well solve the problem of lithology identification in reservoir quantitative prediction. In view of the fact that the measured acoustic wave time-lag curve of buried hill in Zhangdong is not obvious to the lithology of sand and mudstone and the reservoir inversion can not be predicted, the pseudo-acoustic construction technique is adopted to integrate the natural lithology sensitivity The potential curve is converted into a pseudo-acoustic curve, and the purpose of reservoir prediction is fulfilled as a constraint condition, and a good application effect is achieved.
