基于属性融合技术下天然气水合物甜点储层预测——以中国南海台西南盆地A区为例

Prediction of Natural Gas Hydrate Dessert Reservoir Based on Attribute Fusion Technology——Take Area A of Southwest Tai Basin in the South China Sea as an Example

中国南海台西南盆地地质条件复杂,水合物甜点储层预测难度较大。为了达到有效刻画甜点储层的目的,本文以台西南盆地A区为试验区,重点采用一项针对性的关键技术--地震属性融合技术,并重点阐述了多次迭代及分级属性融合技术流程,在此基础上,开展试验区振幅、频率、相位属性融合,并结合地震拟海底反射BSR特征,实现了A区水合物甜点储层的有效刻画,该方法可以作为水合物甜点储层刻画的有效技术手段,为下一步中国南海台西南盆地水合物勘探指明了方向。

The geological conditions in the southwest Tai basin of the South China Sea are complex and it is difficult to predict the hydrate dessert reservoir.In order to achieve the purpose of effectively depict the dessert reservoir,in southwest Tai basin area A test area,this paper mainly adopts a corresponding key technology,seismic attribute fusion technology,and expounds the multiple iterations and classification attribute fusion technology process.On this basis,we carry out amplitude,frequency,phase properties fusion for the experimental zone,and combine the earthquake as the bottom reflection characteristics of BSR,implement the effective dessert area A hydrate reservoir characterization.This method can be used as a hydrate dessert reservoir characterization of effective technical means.For the next step in the southwest Tai basin in the South China Sea it points out the direction of the hydrate exploration.
