声波测井曲线环境校正方法探讨

Research into environment correction with sonic loging

裸眼声速测井是煤层气勘探和开发中普遍应用的一种测井方法,而测井环境对声波时差测井曲线有一定的影响,为了更准确的通过声波时差测井曲线来反映地层的真实情况,采用了补偿声波测井方法,但这种补偿作用十分有限,不能满足实际需要。本文提出了一种声波时差曲线环境效正的方法——漫反射声路法。

Bare eyes sonic logging is a kind of commonly used sonic log method in the field of the exploration and development of coal bed gases, logging environment has some effect on sonic skew log. In order to reflect the real stratigraphic situation through sonic skew log, the compensated sonic logging method is used, but this method is very limited and can抰 meet the practical needs. A novel method for applying environment correction to sonic skew log is presented—an acoustic path scattered reflection method.
