对岩浆岩这一特殊油气藏的储层形成及其孔隙结构特征进行了较系统的阐述 ,认为造成该类储层的决定性因素为构造运动、风化及热液作用等 ,形成了以次生的裂缝为主的复杂孔隙结构类型 ,其储渗空间的分布具有局限性和一定的分散性。由此 ,也造成该类油气藏在分类上的特殊性 ,即按其储层成因的主导因素可分为 :构造裂缝油气藏、古风化壳油气藏及火山碎屑岩油气藏等三大类、若干种 ;提出岩浆岩油气藏在地壳中分布的规律 ,为勘探和开发该类油气藏提供一定的理论基础和评价的依据。
The reservoir formation and pore structure of the special reservoir of magmatic rocks are systematically expounded. It is considered that the decisive factors of this kind of reservoirs are tectonic movement, weathering and hydrothermal action, forming a secondary Fractures of the main types of complex pore structure, the distribution of storage and infiltration space has its limitations and a certain degree of dispersion. As a result, the special classification of this kind of oil and gas reservoirs also can be divided into three categories: structural fractured reservoirs, ancient weathering crust reservoirs and volcaniclastic reservoirs, according to the dominant factors of reservoir origin. And some kinds of them. The law of the distribution of magmatic oil reservoirs in the crust is proposed, which provides some theoretical basis and evaluation basis for exploration and development of such reservoirs.
