摘要: 通过岩心观察、薄片鉴定、测井分析等方法,结合其他地球物理技术,对四川盆地元坝地区上三叠统须家河组三段致密砂岩储层特征进行了研究,结合研究区气井产能特征及主控因素分析,归纳了气藏的甜点类型和成因,并对甜点的分布进行了预测。研究结果表明: ①元坝地区须三段砂岩类型多样,其中中粗粒钙质岩屑砂岩和细砾岩为优质储层;裂缝类型多样,以低角度剪切缝和成岩收缩缝为主。②研究区须三段气藏发育中粗粒钙质岩屑砂岩型和细砾岩型等两大类甜点,结合裂缝特征,可进一步细分为六小类;各类甜点的地质特征、测试方式和试采特征均存在差异。③甜点的形成主要受沉积、成岩和构造作用控制,中粗粒钙质岩屑砂岩和细砾岩多分布于三角洲平原和前缘亚相界线附近的分流河道;差异重结晶是砾缘缝形成的原因;构造活动产生的断层和地层挠曲控制了裂缝的分布。④中粗粒钙质岩屑砂岩和细砾岩均表现为低GR、低CNL、中—高Rd、中等AC值的特征,优质储层的横波阻抗和μρ(μ为剪切模量,ρ为密度)均表现为中—高值,中粗粒钙质岩屑砂岩孔隙型、细砾岩和穿砾缝叠加型甜点呈条带状广泛分布,其他4类甜点零星分布。
