周远田．用ＡＲＭＡ模型恢复薄层测并值．测并技术，１９９４，１８（２）：８７～９３通过各种分析，建立自回归滑动平均模型ＡＲＭＡ（ｎ，ｍ）模拟测井信号，以其逆函数恢复测井值。这是一种新的薄层测井解释方法。本方法能处理各种测井资料，不依赖事先建立的测井响应函数。本文研究了方法的技术基础，解决了有关的问题，并在计算机上获得实现。通过理论测井曲线和实际测井曲线的恢复和分析解释，显示了方法的有效性。

Restoring Log Values of Thin Bed With Model ARMA

An Auto-regressive Moving--average model ARMA(n, m)is established to simulate logging signals. And the inverse function of the simulated signals are used to restore log values.This is a new approach for thin bed interpretation, which can process various log data not depending on pre--built logging response function. This method has been studied technically and used successfully. Its effectiveness can be seen clearly by the restoration of the theoretical and actual logs and the interpretation results of such restored logs.
