In some areas because sand layer was thin in target zones,sonic wave velocity was high in shales,traditional ρimpedance inversion could not be used to distinguish the overlapping of sand and shale rock impedance values,could not meet the needs of subtle reservoir exploration in complex geologic conditions,while pre-stacke elastic parameter inversion had high resolution capacity to lith.
近年来,随着对隐蔽油气藏勘探的日益重视,储层预测技术得到了长足发展,但在某些地区由于目的层砂岩厚度薄,泥岩声波速度高,应用传统的P波阻抗反演,砂、泥岩波阻抗数值互相重叠,无法区分,不能满足复杂地质条件下隐蔽油气藏的勘探需要,而叠前弹性参数反演对岩性识别具有较高的分辨能力。
