| 摘 要： | 从储层的岩石学特征、孔隙的类型和结构以及其物性等方面,对陆东凹陷后河地区下白垩统储层特征进行分析,认为储集层的成分和结构成熟度低。孔隙类型主要有残余原生粒间孔、次生孔、微孔隙和微裂缝四种,以次生孔为主要的储集空间,是油气主要的富集场所。孔喉以微细喉和特细喉为主,孔隙的连通性较差。储层孔隙大小分布不均,具有低孔、特低渗特性。沉积相带和成岩作用是影响储层物性的主要因素,次生孔隙带的发育与溶蚀作用关系密切。 |
| 关 键 词： | 陆东凹陷 下白垩统 储集层特征 孔隙结构 次生孔隙 储层物性 |

| Abstract: | Reservoir characteristics of lower cretaceous in Houhe of Ludong sag were analyzed from the petrology, pore types and structure, petrophysics etc. The textural and compositional maturation of the Houhe reservoir is low. There are four kinds of pores, such as: remainder intergranular pore, secondary pore, micro-pore and micro-fissure. The secondary pores are major reservoir pore space, in which oil-and gas are enriched. Micro-fine throat and ultra-mini throat are major pore throats with little connectivity. The distribution of pores is odds. Reservoir characteristics are low porosity and ultra-low permeability. Sedimentary facies zone and diagenesis are major affecting factors for pore reservoir structure. The growth of secondary pore zone is closely related to dissolution. |
