摘　　要：江汉断陷盆地潜山发育,且具备基本的成藏地质条件,是该盆地的一个重要的勘探领域,但油气勘探一直未获得突破,其油气成藏模式是倍受关注的问题。利用钻井、测井、地震及分析化验等资料,从潜山成因类型和成藏的基本地质条件方面探讨了古潜山的成藏模式。研究结果表明,万城潜山带、潜北潜山带和通海口潜山带主要形成残丘型块状和层状油气藏;新沟潜山带和天门潜山带主要形成断块型块状和层状油气藏。Burial hills are well developed in Jianghan faulted basin with basic geologic conditions for hydrocarbon reservoir forming, and they are important exploration areas in this basin. However, there is still no great breakthrough in hydrocarbon exploration at present , and the hydrocarbon reservoir forming patterns are always the main problem of being paid great attention. Based on drilling,logging, seismic, analyzing and testing results,the patterns of hydrocarbon reservoir forming are discussed from the genetic type and geologic conditions for hydrocarbon reservoir forming of the buried hills. The research results indicate that hammock massive or bedded oil reservoirs formed in Wancheng, Qianbei and Tong-haikou buried hill belts and fault block massive as well as massive bedded oil reservoirs formed in Xingou and Tianmen buried hill belts. It provides a foundation for the exploration potential e-valuation and planning in the buried hills.
