| 摘 要： | 辽河油区龙湾筒凹陷的碎屑岩以砾岩、砂岩和泥岩为主，其储层的储集空间类型主要有粒间孔隙、粒内孔隙和裂缝。最有利的储集空间是粒间孔隙。储层物性的影响因素主要为泥质含量、颗粒分选性和成岩作用三个方面。成岩作用类型主要有机械压实作用、胶结作用、交代作用、溶解作用及矿物成分的转化和重结晶作用；其中交代作用和溶解作用是影响储层物性的主要地质作用。龙湾筒凹陷碎屑岩分布广泛，且具有形成中小型油藏的能力，是辽河油区外围盆地勘探的新领域。

| Abstract: | The Longwantong depression is a prospecting target in the periphery of the Liaohe oilfield. Clastic rock reservoir in the Longwantong depression consists mainly of conglomerate, sandstone and mudstone with accumulation space as intergranular pore, intragranular pore and fissure. The reservoir character is controlled by mud content, degree of sorting and diagenesis. The diagenesis includes compactibility, cementation, metasomatism, dissolution, and recrystallization of minerals. |
