摘要
辽东湾前第三系地层中有元古代的花岗片麻岩与混合岩、中生代的中基性—酸性的火成岩及火山碎屑岩。应用自然伽玛能谱测井、密变测井等核测井资料为主,结合大量钻井取心分析资料对上述岩石进行测井解释。通过对地层岩性分类,建立测井岩性数据库。用判别分析方法对资料进行归类识别,从而计算它们的孔隙度;并利用多种测井方法对这些岩石的裂缝发育程度、孔隙类型、储层进行评价,取得较明显的效果。
Pretertiary of Liaodong Bay consists of Proterozoic granitic gneiss and migmatite,and Mesozoic igneous and volcanoclasties. On the basis of gamma ray spectrum and density log data together with a great deal of cores,logging interpretation is made to differentiate lithologies in order to establish logging lithology data bank.Their porosities are calculated with the bank.In addition,fracture development and pore feature of the rocks could be studied with multiple logging techniques to evaluate reservoir characters.Finally this study witnessed satisfactory results.
