摘　　要：致密砂岩油气资源潜力巨大,但由于其岩性致密、基质孔隙结构复杂且非均质性强.储层含油气性和产能对裂缝的依赖性强,裂缝的测井识别与评价是致密砂岩储层油气勘探开发的关键.致密砂岩储层本身的非均质性以及裂缝分布复杂、规律性差导致目前尚缺乏一个能全面解决裂缝精细描述与刻画的研究方法,在地下裂缝识别和裂缝参数定量表征方面都尚未形成完整的方法理论体系.本文由此拟从裂缝发育控制因素出发,对裂缝分类方案进行归类总结,最后就测井资料在裂缝定性识别和裂缝参数定量表征方面的应用做一综述,以期能弥补裂缝性致密砂岩储层测井评价的薄弱现状,并有助于裂缝空间分布预测的研究.The tight sandstones are of great potentials for oil and gas exploration,however,they are often characterized by dense lithology,complicated matrix pore structure with strong heterogeneity. The oil and gas bearing properties and productivity are strongly dependent on the fracture development,so the logging identification and evaluation for fractures are of great importance for the petroleum exploration and development for fractured tight sandstones reservoirs.But on the other hand,due to the internal heterogeneity and complexity of fractures tight sandstones,there are no logging methods available to solve the all problems encountered in the detailed description and characterization of fractures,and there are no complete method and theory systems for the fractures identification and quantitative characterization of fracture parameters.This paper,aims at the application of logging curves in the qualitative analysis and quantitative calculation of fractures,summarizes the classification scheme for fractures from the geological factors controlling the fracture development.It is hoped that the research results would make up weak research status in logging evaluation of fractures,and could provide guidances for the space distribution research of fractures.
