【摘要】 从冀中坳陷晋陷凹陷沙三段岩性圈闭成藏背景人手,充分利用现有地震资料,综合运用地震波形、地震多属性、相干体、波阻抗反演等多种技术手段,刻画出砂体的形态,并深入解剖了研究区的岩性圈闭成藏重要条件,完成了岩性圈闭的井位标定。背景分析定方向、相干分析找异常、沉积分析明相带、储层预测描砂体、综合分析定圈闭是岩性圈闭研究的有效的工程程序和方法。更多还原

【Abstract】 Starting from understanding the reservoir forming background of Es₃ lithologic traps in Jinxian sag,fully using the current seismic data,and comprehensively applying multiple techniques such as the seismic waveform technique,the seismic multi-attribute technique,the coherence cube technique,and the wave impedance inversion technique,the sand bodies are described,and the important conditions for forming reservoirs in lithologic traps in the studied area are deeply analyzed.Finally the well site locations of lithologic traps are fulfilled.The paper shows that the following methods are effective to the researcb on lithologic traps,such as the background analysis to set orientation,the coherence analysis to find out abnormality,the sedimentary analysis to identify facies belts,the reservoir predication to describe sand bodies,and the comprehensive analysis to determine traps.更多还原
