地震勘探直接找油气在国外的最新发展

Direct hydrocarbon detection via seismic prospecting:A review of overseas advances

介绍了美国The Leading Edge杂志第21卷第10期地震属性专辑中的主要地质成果,包括:用综合地震反演求泊松比,用参数谱估计求吸收系数,用密度数据体直接找油气的成果,寻找河道砂、高孔隙带、高裂缝带等含油气特殊圈闭的10个成功实例,预测超高压带以预防钻井风险成功的实例和两个油气预测失败的例子。着重指出,为了使地震属性技术和人工智能技术在直接找油气方面富有成果,地质家和油气工程专家应持有的态度,以及要使属性技术上升为属性科学所要继续研究的问题。

This paper reviews the special issue of The Leading Edge on seismic attributes. Dixrect hydrocarbon de- tection with seismic attributes has been developed rapidly since 1990s. The main achievements observed from the issue include calculation of poisson's ratio with integrated seismic inversion, absorption coefficient estimation with parametric spectrum, direct hydrocarbon detection on density volume, 10 examples of successful prediction of oil- bearing traps such as channel sand, high porosity zone, highly fractured reservoir, an example of successful pre- diction of overpressure zone, and two examples of failed hydrocarbon prediction. The author tries to elucidate what attitude people should take towards more effectively detect hydrocarbon, increase drilling success rate, and upgrade from attribute techniques to attribute science, by using seismic attribute analysis and artificial intelligence technology.
