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。
In modern oil and gas exploration, the use of seismic inversion data to predict reservoirs and reservoirs is a very effective method. It is an important means to improve the utilization of seismic data and increase the success rate of oil and gas exploration. The RM wave impedance inversion gives full play to the advantages of high vertical resolution of well logging data and rich horizontal information of seismic data. Constraints are obtained from logging wave impedance data and controlled by layers of seismic interpretation. From well points First of all, starting from the side of the well, all the seismic traces are extrapolated to a detailed wave impedance inversion profile, and then the wave impedance inversion data body is obtained, which can be used for reservoir sandstone and stratigraphic lithologic reservoirs Prediction of distribution range. In this paper, the practical application of the Nugda structure to achieve better results as an example, describes the application of RM inversion method in the formation of lithologic reservoirs.
