复杂沉积区内低渗-致密薄储层分级表征下的"甜点"预测
Petrochemical Industry Technology（2023）
Abstract
随着低渗-致密油气藏纳入油气开发范畴,"甜点"分布的有效预测是该类油气藏高效开发的关键.主要应用储层分级表征的地震预测技术,采取以定性的沉积环境、半定量的储层预测到定量储层预测下逐级深入的储层展布研究为指导;综合利用地震反射结构分析、波形指示预测、地质统计学反演为手段提高有效储层预测的可靠性,进而确定优势储层平面分布,并通过平面叠合进行"甜点"分级;针对"甜点"分级以分步钻探实施,滚动开发,实现对复杂沉积区内低渗-致密油气藏低风险、高效的开发.
