在储集层划分的研究中,针对活度曲线变化缓慢,且在反映测井曲线层序界面方面能力较差的问题,设计了一种综合活度分析的处理方法.针对不同测井曲线在储集层的地质特征,采用不同窗长计算其综合活度曲线,通过计算标准差,剔除其中差异较大点,选择差异较小点的平均值作为最终分层结果.实验结果表明,该方法比单纯选用一种窗长、一种测井曲线计算活度曲线划分层序界面深度更准确.

In the research of reservoir division,aiming at the problems of the shorter of the calculation window,the weaker of the noises reduced ability and the sharper of the activity curve amplitude,a method based on the comprehensive activity analysis of reservoir division is put forward in this paper.According to the different geological features of different logging curves in the reservoir,the comprehensive activity analysis curve is calculated by using different window,the quite different points are removed by comparing the standard deviation,the average value of little different is selected as the result of final hierarchical.Experimental results show that it is more precise than simply choose one kind of calculation window and curve.
