摘要: 中国致密砂岩气经过10余年的大力发展,目前已成为仅次于美国、加拿大的致密砂岩气生产大国,勘探效果显著,但“如何效益勘探开发”已成为致密砂岩气藏的核心问题,其富集高产主控因素研究迫在眉睫。针对此问题,以四川盆地中部须家河组二段为例,通过对高产气井的解剖,从沉积环境、储层、烃源、构造及成藏等基本地质特征入手分析了富气区高产主控因素,进而探讨天然气高产富集模式。研究取得两方面认识:一是须二段天然气富集高产主要受五大因素控制,且不同区域其侧重点不一。具体表现为古隆起宏观上控制了高产气井的分布,高产气井主要分布在构造圈闭或鼻凸,裂缝是形成高产气井的重要因素:①在隆起带,优质储层对形成高产气井的贡献相对较强;②在斜坡带,烃源的贡献作用更为明显。二是川中地区须二段主要表现为“3种成藏模式、2类油气高产富集模式”,具体表现为川中东部合川—营山地区主要为相对优质储层控藏模式、川中西部中台山—秋林地区则为顶部薄储与下伏巨厚的烃源组合模式及川中中部蓬莱—公山庙地区过渡成藏组合。前者富集高产模式表现为构造—优质储层模式,后两者则为储渗体模式。基于这些富集高产因素与模式初步预测了下一步勘探方向及重点勘探领域,以期能指导该区致密气的高效勘探开发。
