大邑构造须家河组气藏的裂缝识别

裂缝性油气藏研究中,裂缝识别一直是测井解释的难点。在详细对比分析了大邑构造的成像测井和常规测井响应特征之后,通过"双刻度法",即利用岩心刻度成像测井资料,再用成像测井刻度常规测井,综合各种生产、动态资料,对大邑地区裂缝的常规测井响应特征进行研究,建立了应用常规测井资料进行裂缝识别的模式,确定了大邑各井的裂缝平面分布规律。

Fracture identification for gas reservoir of Dayi structure on Xujiahe formation

During fractured reservoir research,fracture identification is always difficult to be achieved in well log interpretation. After detailed analyzing and correlating the response characteristics of Dayi structure based on FMI and conventional logging,through the double scale method using the core scale imaging well logging data and imaging well logging scale conventional well logging,with the combination of various production and dynamic data,the general response characteristic of Dayi structure on Xujiahe Formation was studied,thus fractures identification model by means of conventional well log data was established.In the end,the plane distribution of the fractures in Dayi structure was revealed.
