准噶尔盆地南缘柴窝堡构造裂缝型储层测井评价

Logging Evaluation of Fractured Reservoir in Chaiwopu Structure in the South of Junggar Basin

根据准噶尔盆地南缘柴窝堡地区上二叠统芦草沟、红雁池组储集岩特点,总结分析了砂砾岩裂缝型储层测井曲线响应特征。以岩心裂缝型储层描述资料为基础,对地层倾角测井资料进行特殊处理,突出裂缝型储层所引起的电导率异常,处理结果表明具有高电阻率背景的砂砾岩致密储集层,裂缝型储层段电导率异常特征明显,能够有效指示裂缝储层发育段,在此基础上,综合利用测井资料,结合岩心描述资料,对该区裂缝型储层分布规律进行了分析和评价。

According to the reservoir rock characteristics of Lucaogou formation and Hongyanchi formation of Permian system in Chaiwopu area in the south of Junggar basin, response characteristics of sandstone ＆ conglomerate fractured reservoir are researched. On the base of core fractured reservoir description data, electric conductance abnormality of fractured reservoir is emphasized on High-resolution Dipmeter Tool （HDT） data characteristic processing. The processing result makes know that electric conductance abnormality characteristic of fractured reservoir is obvious in competent reservoir of high resistivity sandstone ＆ conglomerate and fractured reservoir segment is indicated effectively. So distributing orderliness of fractured resistivity is analyzed and evaluated on the base of the comprehensive exploitation of logging data and core description data.
