【摘要】 风化店火山岩油藏属火山岩潜山油藏，储层岩性复杂，为裂缝－孔隙型双重孔隙介质。为了进行该油藏的油藏描述，通过测井资料的多井综合分析，评价了风化店火山岩油藏的岩相、地质构造、储层物性参数的空间分布规律、裂缝带的分布规律和油水分布规律，基本上搞清了油田产量下降快、含水上升快的主要原因，为石油储存量的复算，优化开发方案提供了可靠的依据。更多还原

【Abstract】 Fenghuadian igneous reservoir is a buried hill, dual porosity reservoir with complex lithology. For reservoir description, its lithofacies, geological structure, the spacial distribution law of the reservoir petrophysical parameters and the distribution law of oil and water and fracture zone are studied by multi well analysis. By synthetical study, the main reasons for the fast decreasing of oil output and the sharp rising of watercut have been found out, thus preparing the ground for reserve recalculation and optimization of development scheme.更多还原
