摘　　要：从商 741地区测井资料及试油试采资料入手 ,结合钻井取心、测井资料及地震资料等相关资料 ,根据有关公式计算出了裂缝的产状和张开度及储层特征 ,对储层裂缝系统中裂缝的产状、张开度和储层的孔隙度、渗透率、饱和度进行了室内研究 ,并对火成岩成因油藏进行了分析 ,找出了一种适合该区火成岩储层的评价方法 .通过储层评价 ,确定了 4类储集层并划分出了储层的有效裂缝带 ,从而确定了该区原油分布的主要规律 ,以期指导该区的开发方案设计 .The standard is presented for dividing the quality grades of fracture igneous rock reservoir according to reservoir porosity and fracture density, and the quality grades of the igneous rock reservoir in Shang-741 well-block are divided. The reservoir characteristics of the igneous rock in the area are analyzed. The formulas of calculating the occurrence and opening degree of fracture and the porosity, the permeability and saturation of igneous rock reservoir are also presented, and the evaluation of this kind of reservoir can be carried out according to the five parameters. Through the evaluation of the reservoir in this area, the effective fracture belt and the crude oil distribution in this area are determined. The study result in this paper can guide the design of development plan of this area.
