摘要: 在现代油气勘探中,利用地震反演资料进行储层和油藏的预测是一项非常有效的方法,它是提高地震资料利用率,提高油气勘探成功率的重要手段.RM波阻抗反演充分发挥了测井资料纵向分辨率高以及地震资料横向信息丰富这两大资料的优点,以测井波阻抗资料为约束条件,以地震解释的层位作控制,从井点出发,首先由井旁道开始对所有地震道进行外推内插出一个详尽的波阻抗反演剖面,然后得到波阻抗反演数据体,以此可用于储层砂体及地层岩性油藏的分布范围的预测.本文以在实际应用中取得较好的应用效果的努格达构造为例,讲述了RM反演方法在地层岩性油藏中的应用情况.

Abstract: In modern oil and gas exploration,it is an effective approach to make use of seismic inversion's data for prediction of reservoir and oil reservoir.That can be enhanced the seismic data's utilization efficiency and improved success ratio in oil and gas exploration.RM inversion has illustrated two characteristics.That is the resolution of the log data's longitudinal direction and seismic data horizon direction is high.The condition is constrained by log data and ontrolled by seismic interpretation's horizon.At first,the wave impedance's inversion section comes from the seismic trace of well to seismic data base,leading to calculation of wave impedance inversion's data base and prediction of reservoir sandstone body and oil reservoir's area.In this article,an application example comes from Nugeda area in Erlian Basin,describing stratigraphic and lithological oil reservoir by use of RM inversion.

Key words: petroleum exploration, wave impedance inversion, Nugeda structure, lithologic oil reservoir
