综合地球物理方法识别准噶尔盆地的岩性圈闭

岩性圈闭研究的关键在于圈闭的识别和评价方法的逐步完善。通过对新疆准噶尔盆地岩性圈闭识别技术的研究，全面介绍了近年来广泛应用的各种岩性圈闭识别手段和分析技术。从沙南二叠系梧桐沟组岩性油藏的探明和阜5井南侏罗系三工河组岩性圈闭的发现等典型勘探实例出发，从技术手段、工作流程上探索适用于准噶尔盆地岩性圈闭识别的研究思路和识别规范，以便为今后岩性圈闭和油气藏的勘探开发提供借鉴，这对准噶尔盆地的油气勘探工作具有重要的现实意义。

Discussion on identifying method for Identification of lithologic traps in Junggar Basin by comprehensive geophysical method.

The key of lithologic trap study depends on the gradual development and improvement of methods for lithologic traps.Through studying the distinguishing technique of lithologic traps in Junggar Basin,Xinjiang,the paper introduced comprehensively the identifying tools and analyzing techniques of different lithologic traps which widely used in recent years.Starting from the real exploration cases such as lithologic reservoir in Wutonggou Formation of Permian in Shanan and lithologic traps in Sangonghe Formation of Jurassic in south of Fu 5 well,the paper discussed the identifying methods of lithologic traps and sought the studied ways and the identifying rules suitable for Junggar Basin from technique and work flow,which provided valuable experiences for later exploration and development of lithologic traps and reservoirs and has an important realistic and strategic meaning for oil gas exploration in Junggar Basin.
