摘要(Abstract):
针对储层预测研究过程中,当波阻抗不能有效识别砂体时,如何利用对储层有良好分辨能力的测井曲线开展储层反演研究工作,提出一种行之有效的重构声波曲线反演方法。给出了计算重构声波曲线的数学模型,利用重构的声波曲线进行储层横向预测,并进一步指出利用正反演结合进行储层预测的发展方向。
Aiming at the process of reservoir prediction,when wave impedance is not effectively identified sandbody,this paper proposes an inversion method of effective rebuild acoustic curve to use well log curve to develop reservoir inversion.Meanwhile,mathematical model which applies to calculate rebuild acoustic curve is given.It can be applied to predict reservoir lateral model.This paper points out reservoir prediction development direction combining with forward and inversion.
