摘　　要：隐蔽类油气藏同构造类油气藏一样,目前已成为我国油气勘探工作的重点领域,而且随着勘探工作的深入,隐蔽类油气藏必将是油气储量增长的主要来源。裂缝性油气藏是隐蔽类油气藏中最为复杂、勘探难度最大且产量较高的一类油气藏。为了提高裂缝性油气藏的勘探成功率,以辽河盆地火山岩裂缝油气藏的勘探为例,在分析和研究不同类型裂缝性油气藏的测井响应特征,利用电导率测井、声波测井、放射性测井和地层倾角测井等测井方法对裂缝性储层进行测井识别的基础上,引进分形模型方法对裂缝性储层的表征参数———裂缝发育程度和裂缝密度进行了定量预测,从而达到对裂缝性储层的孔隙度进行定量评价。The subtle reservoir, just as the structural reservoir, has become the important hydrocarbon exploration target. Moreover, with further exploration, the subtle reservoir will be the main resource to increase hydrocarbon reserves. The fracture reservoir is one kind of subtle reservoir , and this kind of reservoir is the most complicated, and the most difficult to exploit with the highest production. The exploration success rate of fracture reservoir needs to be increase. For example, during the exploration of volcanic fracture reservoir in Liaohe basin, the fractal model approach was introduced. In this example of Liaohe basin, based on the analysis and research on the logging response characteristics of different types of fracture reservoirs, resistivity log, acoustic log, nuclear logging, dip-log and other logging methods were used for the identification of fracture reservoir. At the same time, the fractal model was used to quantitatively estimate the characterization parameter of fracture reservoir, fracture developmental degree and fracture density. Then, the porosity of fracture reservoir could be quantitatively evaluates.
