THE STUDY ON THE METHODS USED TO DELINEATE THE DEEP TIGHT GAS BEARING SANDS IN DAQING OIL FIELD

针对大庆地区深部致密砂岩气层具有岩性复杂、物性差、侵入浅的特征，提出了一套相应的气层判别方法。

Abstract We present a set methods used to delineate gas bearing zones based on the com-plex lithology,poor pertophysical properties and xhallow invasion of mud filtrate in the deep tight gas bearing sands in Daing Oil Field, Practical application shows the methodscan delineate gas bearingh sands.SUBJECT TERMS:tight sand . logging interpretation model
