【摘要】 虚拟三维地震是基于二维地震数据建立的包含所有二维测线信息的三维地震数据体。本文依据此方法在三江盆地绥滨拗陷建立了虚拟三维数据体,进行地震反演,提取了泥岩厚度图,并与地震相研究结果进行对比分析,明确了烃源岩分布详情,为有利区带划分和综合评价提供了更加可靠的基础资料。因此,虚拟三维地震技术可望推广应用于其他仅有二维地震资料的地区。更多还原

【Abstract】 Hypothesized 3D seismic volume is established based on all the 2D survey lines of the work area.By hypothesized 3D seismic volume in Suibin Depression,Sanjiang Basin,we carry out seismic inversion,and draw a mudstone thickness chart.Based on a contrastive analysis with seismic facies,a clearer hydrocarbon source rock distribution is obtained,which can provide more reliable information for the future exploration.Results show that hypothesized 3D seismic technology may play an important role of the exploration in the area which only has 2D seismic data.更多还原
