【摘要】 裂缝是潜山油气藏的重要储集层 ,潜山的油气产出与裂缝的发育情况密切相关 ,因此 ,对裂缝发育控制因素和裂缝发育规律进行了分析和探讨。尽管单条裂缝在地震资料上难以识别 ,但是裂缝带在地震资料上有其特征。描述了裂缝储层的地球物理特征 ,并利用测井约束反演技术、吸收系数技术、地震相分类和相干分析技术对潜山储层进行预测。通过在车古 2 0 1潜山的应用实例分析 ,说明以上 4种储层描述技术比较有效

【Abstract】 Fractures are important reservoir spaces in buried hill reservoirs. The production of a buried hill reservoir is directly correlated with the growth of fracture. In this paper we analyzed the factors controlling the growth of fracture and discussed the rules of fracture growth. Although single fracture is hard to be identified in seismic data, fracture zone has its own seismic characteristics. Based on the geophysical characteristics of fractured reservoir, we use logging constrained inversion, absorption coefficient, seismic facies classification, and coherence analysis to predict buried hill reservoir. The effectiveness of the above four technologies in describing buried hill reservoir is confirmed by the case study on the Chegu201 buried hill reservoir.
