深部气层和干层的模糊模式识别

深部气层和干层的区分是常规测井解释的一个困难问题，文中依据东濮凹陷深层试采资料，并参考诸多测井解释的可能气层，建立了两个模式各四个参数的隶属函数，拟定了两个模式各参数的权分配，经该地３０层试采层验证，效果良好，因此模糊模式识别对区分深部气层和干层是一种值得借鉴的方法。

Distinction between Deep-beared Pays and Tight Formation with Log Fuzzy Patterns

It's difficult to make a distinction between deep gas-beared pays and tight formations with conventional method. New knowledge comes from recent work. This paper, based on the producing tests data of Dongpu Depression as well as on possible gas -- beared pays of many wells with log interpretation, establishes functions of membership degree about two patterns with four parameters and draws up coefficients of weight about two patterns with four parametors verified by informations of 30 wells, the applicability of method is available on the relativeaspects.
