摘要
以解决工程实践难题为目的,首次提出了根据换能器与薄层所处位置不同,分别利用其不同求薄层厚度公式之观点。研究了声波测井薄层厚度定量计算公式,详细介绍了公式在高背景上检出Vp低值薄层,在低背景上检出Vp高值薄层的应用情况。并就薄层纵波速度的获取以及如何选用合适计算公式等问题作了一些探讨。同时,通过实例证明了这些措施对提高薄层厚度定量计算精度的重要性。
In order to solve the problems in engineering practice,this paper proposes the use of different thin layer thickness formulas according to the thin layers in different locations on the basis of the transducer for the first time.The paper introduces in details the application of the examination of thin layer thickness with high-value Vp in low background and low-value Vp in high-value background.This paper has also discussed the following two points:the capturing of longitudinal wave velocity and the choosing of appropriate formulae,in order to demonstrate that these measurements are of importance to raise the accuracy of the thin layer thickness calculation.
