宽频带重构反演在喇嘛甸油田北东一区萨尔图油层的应用
|
摘要
为了解决开发地震密井网区薄砂岩预测的难题,从喇嘛甸油田北东一区萨尔图油层研究出发,利用初始模型对波阻抗反演进行低频恢复;同时借助拟波阻抗重构反演进行高频补偿,从而实现了宽频带重构反演。重构后反演结果不仅能够识别出大于5m的厚砂岩,同时能够识别约2m的薄砂岩储层。通过准确定位垂向上砂体间接触关系、砂体的空间展布,最终完成井震联合沉积相修正,以此为薄砂岩剩余油研究提供了可靠的分析依据。
There is a problem in forecasting thin sandstone in development with the earthquake in the area with dense well network.The research was done on Saertu oil bed in the first northeast area of Lamadian reservoir.Make use of the fuzzy system as recovery of the low frequency of the wave impedance inversion,and use the para-wave impedance remodeling inversion as the compensation of the high frequency,the broadband remodeling inversion came true.The remodeling inversion result not only the thick sandstone more than 5 meters and the thin sandstone less than 2 meters could be recognized.As a result,sedimentary phase modified by well to seismic integration after the vertical contact and spatial distribution of sandstone accurately locating,provided the reliable analysis inference for the research of the remaining oil in the thin sandstone.
