大牛地气田奥陶系岩溶缝洞型储层识别预测方法OA
Identification and prediction methods for the karst fractured-vuggy reservoir in the Ordovician Formation of Daniudi gas field
大牛地气田下古生界气藏主要发育中小尺度岩溶缝洞型储层,与塔里木盆地、四川盆地相比,缝洞定量识别评价难度大.通过岩心、薄片、常规-成像测井及物探等资料,明确了岩溶缝洞型储层类型和发育特征,形成一套储层定量识别和储层预测方法,主要取得了以下认识:①结合地质特点,将研究区储集岩的孔隙类型划分为孔隙型、裂缝-孔洞型和缝洞型三大类,建立了岩溶缝洞型储层综合识别模板;②通过基于贝叶斯准则的逐步判别法实现了不同类型储层定量划分,判别模型解释的储层类型与实钻资料…查看全部>>
The Lower Paleozoic gas reservoir in Daniudi gas field is mainly formed by medium and small scale karst fractured-vuggy reservoirs,it is difficult to identify and evaluate fractured-vuggy quantitatively compared with Tarim and Sichuan Basins.Based on core,wafer,convention-imaging logging and geophys-ical data,the types and characteristics of karst fractured-vuggy reservoirs have been defined and we devel-oped a set of quantitative identification and predicti…查看全部>>
