渤海海域AVO技术应用效果分析——以JZ31—1构造为例

AN APPLICATION ANALYSIS OF THE AVO TECHNIQUE IN BOHAI SEA:A CASE STUDY OF JZ31-1 STRUCTURE

随着油气勘探方向逐渐向寻找隐蔽型油气藏转化,AVO技术已愈来愈得到人们的重视.文中以渤海海域JZ31-1构造为例,结合地质、测井和叠前地震资料,对叠前地震信息随偏移距变化与油气关系进行了分析,结果表明,应用AVO属性分析对该区有利勘探目标进行烃类检测是可行的.

With the exploration direction turning to subtle reservoirs, more and more emphases are put on the AVO technique. Taking JZ31?1 structure as an example, this paper has analyzed the relationship between pre_stack seismic changes with offset and hydrocarbon occurrences, combining with the geologic, logging and pre_stack seismic data. The results have indicated that the AVO technique is useful to detect hydrocarbon for favourable targets in Bohai Sea.
