用声速测井和侧向测井研究岩石的各向异性

A Study of Anisotropy in Rocks with Acoustic Vclocity Log and Laterolog

各向异性——岩石的重要物理性质之一,没有一种地球物理方法能测出理藏条件下岩石的各向异性。本文提出利用声波速度测井和侧向测井研究岩石的各向导性,并推导了有效的计算方法.作为一种应用,又研究了由各向异性确定油、气储集层孔隙结构的数学—物理模型,还在已有岩心资料的井中进行了检验。

Anisotropy is one of the important rock properties. A method studying rock anisotropy with acoustic log and laterolog is proposed. Its calculation method is derived. As an applica-tion, a mathematical-physical model determining reservoir pore structure has been re-searched with anisotropy. The result is comfirmed with core analysis data.
