Abstract:
Nodular and banded chert distribute extensively over the4th interval and underlying strata of the Ordovician Yingshan formation in Tahe oilfield in northern Tarim basin. Researching the logging response characteristics of chert and distinguishing the chert?developed formation are of significance to the evaluation of effective reservoir, formation zonation, and stratigraphic correlation. This paper discusses the basic principle of identifying chert by using imaging well logging, chemical element logging and litho?density logging data, and establishes the method for chert logging identification by means of these data and photoelectric absorption cross?section index curve. Taking the chert intensive development section near the bottom margin of Yingshan 4th lithologic interval as marker bed, it makes the stratigraphic correlation of partial strata and resolves the problem of the Middle-Upper Ordovician denudation estimation in Tahe oilfield
