Abstract: The response characteristics of logging on low-resistance oil layer is not obvious,which often decreases the level of interpretation of low-resistance oil layer,even lose it; thus causes loss for oil field developing. This article combines the condition of production in low-resistance oil layer on turbid reservoir in Shinan oil field, deeply research multi-well geology and log information,and analyze relation of lithological composition, physical attributes, property of oil-bearing and electronic attributes of low-resistance oil layer. It studies sensitive factors on low-resistance oil layer, and confirms the existence of low-resistance oil layer in this field. It also explores methods to decide and interpret low-resistance oil layer by conventional series log curves such as analogy of reservoir characteristics of multi-well and spontaneous characteristics between oil layer and water layer. It is helpful to identify oil-bearing formation with low resistance.
