摘要
裂缝孔隙度是评价裂缝性储集层的关键参数。FM I成像测井评价裂缝孔隙度较为精确,但其成本较高,应用受限。常规测井资料具有经济实用,应用广泛的特点,采用裂缝双侧向测井响应快速解释方法计算裂缝孔隙度,并用FM I成像资料提供的裂缝孔隙度对其进行标定,建立二者之间的定量关系。实际处理资料表明,应用双侧向测井资料计算裂缝孔隙度,在经过FM I成像资料标定后数值准确,得到的储层解释结论与试油结论符合,为应用常规测井资料评价裂缝孔隙度,提供了有效的方法。
Fractured porosity is a key parameter to fractured reservoir evaluation.Although the well logging data of FMI are efficient in the fractured porosity evaluation,its cost is high and so its application is limited.As conventional well logging data are of economical and wide application characteristics,the fractured porosity was computed by the fast interpretation method with dual laterolog response to fracture and calibrated by the FMI data.By real data processing,it is found that the fractured porosity computed with dual laterolog response is accurate after calibrating by the FMI data and be in good agreement with testing results.This shows a prospecting application to evaluate fractured porosity using conventional well logging data.
