摘　　要：本文应用岩心、薄片、测井等资料,以火成岩岩相研究为基础,重点研究了火成岩储层裂缝特征,认为研究区内裂缝以成岩缝和构造缝为主,大多为小裂缝,呈网状分布,形成了有利的储渗空间体系。裂缝的发育方向总体上以北东向为主,北西向为辅。研究区以气孔玄武岩、火山角砾岩和凝灰岩中裂缝最为发育,是较有利储层。With the data of drill core, thin section, well logging and igneous rock facies, the characteristics of the fractures in igneous rock reservoirs are studied in Zaoyuan area, Huangbua depression. Researches show that the main fractures are the diagenetic fracture and structural fracture, mainly small fractures, distributed in grid, formed the favorable reservoirs. The northeast fractures are given priority to, northwest is complementary. The vesicular basalt, volcanic breccia and tuff are the main reservoirs of igneous rocks in this area.
