| 摘 要： | 渤海海域A构造区沙二段高孔高渗型混合岩类储层的发现改变了此区缺乏优质储层的认识.以钻井取心化验资料为基础,综合分析了该类储层的岩石学特征、沉积成因、储层特征及影响因素.研究认为该类储层是受间歇性陆源供给影响的混合沉积产物,沉积相带是影响储层质量的主要因素,后期混合白云石化对储层质量保护及改善具有积极作用.

| Abstract: | The discovery of high porosity and high permeability reservoirs has changed the traditional understanding about reservoir quality in E3s2 in A structural area, Bohai Sea. On the basis of the drilling core and the laboratory analyzing results, study has been conducted on the lithologic characteristics, sedimentary genesis, reservoir characteristics and influence factors on this type of reser- voir. The study results indicate that this type of reservoir was mixed deposits, affected by intermittent local terrigenous supply, and the sedimentary facies is the main factor influencing the reservoir quality. In addition, the later mixed dolomitization has some posi- tive influence on reservoir quality protection and improvement. |
