基于成像测井技术在我国海域含油气盆地的应用积累,提出了碎屑岩成像测井沉积学的概念.碎屑岩成像测井沉积学的主要研究内容包括地层岩性识别、沉积构造解释、沉积序列与微相分析、砂体物源与古流向分析、砂体分布预测等五个方面.利用南海西部的实际资料,运用成像测井技术,对五方面的应用逐一分析或提出了应用前提、使用步骤、注意要点、已有规律特征以及典型实例.

In the light of imaging logging technique that is applied in the offshore petroliferous basins in China, the concept of imagine logging sedimentology for clastic rock is introduced, which deals with the recognition of stratigraphic lithofacies, interpretation of sedimentary structures, the analysis of sedimentary sequences and microfacies, the analysis of sandbody provenances and paleocurrent directions, and the prediction of sandbody distribution. For some classical cases, the imagine logging technique is applied to resolve the available data from oilfields in the western part of South China Sea.
