河流相储层单一河道的识别及其对油田开发的意义

Identification of single channel in fluvial reservoir and its significance to the oilfield development.

利用密井网条件下丰富的测井资料 ,通过储层建筑结构层次分析 ,对主河道、废弃河道、决口水道、决口扇、天然堤、河漫滩成因砂体进行了综合识别 ,其中河道成因的砂体是河流相储层的骨架砂体。总结出识别单一河道边界的五种标志 。

By applying abundant log data in close spacing and layer analysis of reservoir configuration,six kinds of essential genetic sand body are identified comprehensively,such as major channel,abandoned channel,crevasse channel and so on. Among them channelgenetic sand body is the framework of fluvial facies reservoir. Five identifying markers of single channel boundary are summarized. Its significance to the oilfield development is pointed out.
