摘要

深水水道是深水油气勘探的重要领域,勘探实践表明深水水道体系优质砂岩是白云凹陷深水区油气的主要储集体。利用南海北部白云凹陷深水区三维地震资料,综合应用地震—沉积相、相干处理、地震属性等地震技术,对三维工区内珠江组上段深水沉积水道体系展布进行识别,定性分析水道砂岩储层有利相带分布规律;在此基础上,开展岩石物理分析及叠后地震反演储层预测研究,(半)定量刻画水道砂岩储层分布规律及厚度特征,对水道砂岩储层开展综合评价。最终总结出一套适合深水水道砂岩储层识别预测的地球物理综合方法体系。

Abstract

Deepwater channel system is one of the main fields in deepwater hydrocarbon exploration.The exploration practice in the Baiyun deepwater area indicates that the deepwater sandstone is the main reservoir type.Based on high-resolution 3D seismic data of the study area,this paper presents a set of comprehensive geophysics methods that can be used to recognize and characterize deepwater channel sandstone reservoirs.First of all,the distribution of the deepwater channel system in the upper Zhujiang Formation was identified according to seismic-sedimentary facies,seismic coherence and seismic attribute,as a result the favorite facies distribution and sandbody distribution lows of the reservoir were qualitatively understood.And then petrophysical analysis and post-stack inversion reservoir prediction research were conducted,so the reservoir distribution lows and the reservoir thickness were half quantitatively or quantitatively delineated.Recognition and characterization of the deepwater channel might provide some insights for future explorations in the Baiyun Sag.
