摘要
徐闻地区迈陈凹陷涠洲组、流沙港组发育薄层砂岩储层,储层与非储层声波曲线响应差异不明显,用常规波阻抗曲线进行岩性识别效果较差。本文应用曲线重构技术进行精细储层预测研究,系统分析了储层的曲线响应特征,优选出岩性识别效果好、特别是对薄层砂岩响应敏感的伽马曲线作为最优的储层特征曲线,利用原始声波曲线的低频信息及伽马曲线的高频信息,对原始声波曲线进行了重构,并基于测井约束反演方法开展了精细储层预测,并对预测结果进行了分层分析,明确了有利储盖区,取得了良好效果。
Thin sandstone reservoirs are developed in the Weizhou Formation and Liushagang Formation of the Maichen Depression in the Xuwen area.The difference in acoustic response between reservoirs and non reservoirs is not significant,and conventional impedance curves have poor lithological identification results.This article applies curve reconstruction technology for fine reservoir prediction research,and carries out fine reservoir prediction based on logging constrained inversion method.The prediction results are analyzed layer by layer,and favorable reservoir cap areas are identified,achieving good results.
