摘　　要：涩北气田储层具有埋藏浅、成岩性差、胶结疏松、泥质含量高、薄层发育、气水层交互并有边水环绕的特点。通过对涩北气田井下流型的形成机理与测井曲线响应特征分析,提出基于持气率优先的流型划分标准,对于井下主要存在的泡状流、段塞状流和雾状流的不同流动形态,采用不同解释模型分段解释的方法,解释结论与实际生产有较高的一致性。Abstract： The Sebei gasfield reservoir is characterized by shallow depth, worse compacuon, poor cementation, high shale content and gas water interaction with edge water around, so, the output profile logging in such reservoir is more complex than that in the conventional gas reservoir. We analyze the formation mechanism and log curve responses of the underground flows in Sebei gasfield, the flow dividing pattern standard based on prior gas holdup is proposed. According to main flow types in well, such as, bubble shape flow, segment block flow and spray flow, we use different segmentation interpretation methods to effectively improve the accuracy of log interpretation. The practical log applications show that the interpretation conclusions have higher consistency with the actual production.
