【摘要】 以测井响应特征分析为主 ,辅以岩心观察 ,旋回地层学界面识别和地震反射特征分析 ,在孤岛油田新近系明化镇组底和馆陶组馆上段馆 1+2砂层组第四小层底发现两个辅助标志层。这些辅助标志层的发现为孤岛油田地层、构造、沉积与油气分布规律等研究奠定了重要基础。研究成果可作为油田开发中后期河流相小层划分对比研究工作的借鉴。更多还原

【Abstract】 Two auxiliary index horizons were discovered based on the analysis of the logging response characteristics, observation of core, recognition of cyclic stratigraphic boundaries, and the analysis of seismic characteristics. The work lays an important foundation for the study on the stratigraphy, structure, sedimentation and oil distribution and will be used for the substratum division and correlation in the later period of the oil field.更多还原
