| 中文摘要: |
| 文章依据岩心、薄片、FMI成像测井资料对大民屯凹陷太古宇储集岩岩性及有利储集层段进行了分析研究,不仅从岩石成分角度分析了变质岩的主要储集岩岩性,还在应用成像测井识别裂缝及碎裂段的基础上结合常规测井解析了裂缝性油藏的有利储集层段。研究结果表明,大民屯凹陷太古宇变质岩储集层岩性以混合花岗岩为主,混合花岗岩的碎裂段是良好的流体渗流通道,但不易储集油气,而在碎裂段上部及下部的裂缝发育段则是油气的有利储集层段。 |
| 英文摘要: |
| Based on data of core, thin section and FMI imaging log are analyzed the lithology of reservoir and the favorable crack interval for reservoir in Archean bed rock of Damintun sag. Not only lithology of the major reservoirs is analyzed from aspect of the rock's composition but also applied the imaging logging to recognize crack and cataclastic zones and interpret the favorable crack interval for reservoir. The result shows that migmatized granite is the main lithology of Archean reservoir in the sag. Cataclastic interval of the migmatized granite is good passage of fluid but is not the place to accumulate oil and gas. However the crack intervals both above and bellow the cataclastic interval are the favorable interval for reservoir. |
