摘要(Abstract)：

为确定川西新马—什邡地区蓬莱镇组三段气藏沉积、储层特征及其控制因素,利用岩心观察、薄片、物性、压汞曲线等分析,结合地震属性预测等结果,采用地质—地震、宏观与微观相结合的方法开展研究。结果表明:蓬三段由5个砂组构成,各砂组厚度变化较小,反映沉积期构造稳定、地势平缓,蓬三段JP_2~3砂组属于浅水湖盆河控三角洲前缘沉积。细粒岩屑砂岩为JP_2~3砂组主要储集岩,粒间孔为主要的储集空间类型,粒间溶孔、粒内溶孔、铸模孔等也较为发育,以中孔、小孔为主;喉道总体呈差—中等分选、中细歪度,为中—细喉道的特征;孔喉组合总体为中—小孔—中—细喉,渗流能力中等—较差,为典型特低孔—低孔—低渗—特低渗的孔隙型储层。沉积微相是控制JP_2~3砂组储层发育的关键,并控制储层厚度、岩性粒度和充填物成分,导致储层物性和孔隙结构等差异。
