摘要
对勘探程度较低的杭州湾平湖凹陷,以地震资料为主结合地质、测井等资料,运用高分辨率、地震道反演、层序地层学等技术,对凹陷进行横向预测,初步建立了凹陷的层序地层,预测了生油岩和储集层的分布,发现了低速圈闭,提出了有利勘探区和可能产气区。提供的实例表明,运用横向预测技术是普查阶段提高勘探效率的一种手段。
According to seismic data in combination with geological and logging data, using new tech- niques such as high resolution, seismictrace inversion and sequence stratigraphy, etc., the leteral prediction has been performed to predict source rock and reservoir distribution, find low-velocity traps and propose the favorable explorational target and the potential gas-producting area. The given case shows that the leteral prediction techniques are one of the effective method in the initial exploration stage.
