【 摘 要 】

Igneous reservoir, as a deep dominant reservoir, will mostly get high production once developed, but this kind of reservoir has long been the key and difficult point of well logging evaluation due to its complex lithology, various reservoir forming control factors and strong heterogeneity. Lithology identification is the primary task of well logging evaluation of igneous reservoir. Guided by the idea of sequential separation, this paper adopts conventional logging crossplot method and TAS chart method to identify the lithology of igneous rocks successively, meanwhile, the characteristics of igneous rocks imaging logging are summarized. Through the above research, a set of systematic lithology identification criteria for Yingcheng formation igneous rocks has been established.
