潜山油藏中裂缝发育是证明其高储油、高产油的重要标志，可靠地识别和预测潜山裂缝发育段是实现该类油藏有效勘探和开发的关键。首先对井点裂缝进行岩性成分与裂缝特征分析，认为呈浅色矿物的岩性中由于脆性成分含量高，岩石易破碎，裂缝更易发育；在井曲线上，双侧向曲线和声波时差曲线是对裂缝响应较为敏感的常规曲线；并结合地震反射剖面及实际油气井产量，发现在裂缝发育区地震反射呈错乱断续特征且其区域井产能较高，进一步总结出裂缝－地震反射－产能之间的关系；在裂缝检测方面，通过提取对裂缝敏感的地震属性，从单一属性证明了裂缝检测的可行性，再利用敏感的裂缝属性进行多属性融合裂缝预测，综合预测该区在东胜堡和法哈牛构造带、静安堡裂缝最发育，其次为边台、平安堡、静北、前进构造带，而安福屯和曹台构造带裂缝相对欠发育。基于点－线－面逐步推进分析的原则，总结了大民屯地区裂缝段地球物理响应特征，为该区裂缝预测提供依据，进一步指导变质岩潜山油藏勘探开发工作和井位部署。

Fractures in the buried hill reservoir is proved that the important symbol of its high oil storage , high oil production , reliably identifying and predicting buried hill fracture development section is the key to realize the effective exploration and development of such reservoirs .Firstly, for the analysis of characteristics of well point frac-tures and lithologic composition thinks of light-colored rock mineral ingredients due to the high brittleness is easily broken , cracks are more likely to develop .On the curve of the well , dual lateral resistivity curves and sonic curves are more sensitive to response fracture development section .Combined the actual seismic reflection profile and oil and gas well production , found that seismic reflection in the fracture development zone is disorder intermittent char-acteristics and its regional well productivity is higher , further sums up the relationship the crack-the seismic reflec-tion-the capacity of wells .In terms of fracture detection , by extracting the crack sensitive seismic attributes demon-strated the feasibility of fracture detection from a single attribute , and then using sensitive multi-attribute fusion technology to predict fracture ,a conclusion was comprehensively drawn that Fort Dongsheng and Fahaniu structural belt, Jing′an Fort crack is the most fracture development;followed is Biantai,Fort peace,Jing north and Qianjin structural belt;fractures of Anfutun and Caotai structural belt are relatively less developed .Based on the principle of point-line-face gradually analysis ,this area fracture section of geophysical response characteristics was summarized , provided the basis for predicting fracture in the region , and further guided the metamorphic buried hill reservoir ex-ploration and development work and well placement .
