低幅度构造识别技术在Carmen油田三维工区的应用
|
摘要
近年来,随着油田勘探开发的深入,规模小,构造幅度低的油气藏所占比例逐年上升,低幅度构造也逐渐受到重视.本文分析了低幅度构造的特点及地震反射特征,结合工区实际情况,提出了在地震资料解释阶段研究低幅度构造的流程和思路,总结了针对低幅度构造的主要识别方法:地震正演模拟、井控提高分辨率处理、层位精细解释、三维速度场分析、构造图倾角校正等.通过以上技术在Carmen油田三维工区识别了12个低幅度构造,结合地质、测井资料综合分析优选了两个钻探目标,取得了较好的勘探效果.
In recent years, with the in-depth of oil field exploration and development, the amaount ratio of small-scale and low amplitude structure reservoirs discovered is climbing and paid more attention gradually. This paper analyzes the seismic reflection characteristics of low-amplitude structure, brings forward the research flow of data interpretation and summarizes the main recognition techniques: seismic forward modeling, well control improving resolution processing; 3-D velocity field analysis; dip logging correct and so on. Through these techniques twelve low-amplitude structures are recognized in the 3-D seismic exploreation in the Carmen field and two drilling objects are optimized baset on the geology and logging information. It received preferable prospect effect.
