提升测井曲线分辨率的一种新的处理方法

A new method on enhancing log resolving power

老油区的测井资料的分辨率不能满足对储层的精细描述的要求,所以对测井曲线的高分辨率处理很重要。一般而言,测井值与地层实际物理量满足第一类积分方程。本文利用第一类积分方程的线性矩解法,提出了提升测井曲线分辨率的一种新的处理方法。计算结果表明,处理后的测井信息与地层的真实情况更为接近,可更好地用于老油区储层非均质区域性评价。

The resolving power of logs in some old exploitative oil regions cannot satisfy the demand for fine description of the old oil region. Hence, it is important to enhance the resolving power of the old conventio-nal logs. Generally speaking, the logging value and the stratigraphical actual physical quantity satisfy the first kind of integral equation. In this paper a new processing method using the linear moment solution of the first kind of integral equation is proposed. The computed results indicate that the method effecteively enhances the resolving power of co - ventional log and makes it more effective in evaluating the territorial heterogeneity of reservoir.
