【摘要】 截至2004年底,济阳坳陷三维地震资料满覆盖面积为21134.72km2,在其主要油气聚集带已经连片。这些资料采集时间跨度大,品质参差不齐。采用定量计算与定性评价相结合所确定的综合评价方法,按不同凹陷和不同区带对161块三维成果资料进行了评价。评价出Ⅰ类资料24块,Ⅱ类资料107块,Ⅲ类资料30块。Ⅲ类资料且具有较大勘探潜力的地区,是今后地震二次采集的重点地区。更多还原

【Abstract】 By the end of 2004, the total area of 3 D seismic datais21 134.72 km in Jiyang Depression, which covers the whole area in the main hydrocarbon accumulation zones. The data are collected in different time with various qualities. 3D seismic data of 161 blocks are evaluated using quantitative calculation and qualitative evaluation according to different depressions. Seismic data of 24 blocks are Ⅰ type, seismic data of 107 blocks are Ⅱ type, and seismic data of 30 blocks are Ⅲ type. Secondary seismic acquisition will be made in the area of Ⅲ type data and great exploration potential.更多还原
