基于岩石物理统计的亮点技术应用分析
|
摘要
地震亮点技术近年来在油气勘探中得到广泛应用。本文依据地球物理岩石正演理论,通过对四个正演模型的分析,讨论不同厚度含气砂岩与围岩(泥岩)的振幅特征;在南海北部深水区L凹陷地区主要含油气层系内,通过纵波阻抗的统计对比,分析了亮点特征差异原因,认为地震亮点特征可作为该区储层预测的重要依据。
Seismic bright spot identification method in oil and gas exploration in recent years have been widely used.According to the basic principle of physical modeling rock,through to the four of forward modeling analysis,discusses different thickness of gas sandstone and surrounding rock(mudstone) amplitude characteristic;Based on the actual well as an example,through its longitudinal wave impedance contrast,analyzes the characteristics of bright spot reasons for difference;Northern south China sea in the deep water area main oil bearing formation L sag,within conventional profile in the bright spot of that can be used as an important basis for the reservoir prediction.
