摘　　要：针对高含水疏松砂岩油藏开展了储层特征解释方法研究。根据测井解释成果,建立储层岩性、物性识别方法,并以A油田为例,分析储层岩性、物性分布特征,进一步深化储层特征解释方法研究,现场应用效果较好,为下一步开发调整提供可靠的地质资料。After a long time of exploitation,due to the horizontal and vertical heterogeneity of the reservoir,there is a large difference in reservoir development,and a large amount of remaining oil is enriched,resulting in low overall recovery degree of the reservoir and high comprehensive water-cut.The reservoir with unconsolidated natural sandstone is more serious.Based on the results of logging interpretation,this paper establishes the identification method of reservoir lithology and physical property,and takes oilfield as an example,analyzes the distribution characteristics of reservoir lithology and physical property,and further deepens the research on the interpretation method of reservoir characteristics,so as to provide reliable geological data for the next development and adjustment.
