【摘要】 潍北凹陷孔二上亚段主要以薄层为主,受多种因素影响,声波测井曲线不能有效反映储层特征。依据本区地质特点和资料情况,以地质、测井、地震综合研究为基础,以岩石物理学为理论指导,利用拟声波技术分析了不同测井曲线对于储层的敏感性,优选出能有效反映岩性特征的自然电位、自然伽马等测井曲线,应用拟声波技术构建储层特征曲线,开展测井约束反演。处理结果表明,该方法在储层预测、岩性识别等方面应用效果较好。更多还原

【Abstract】 The majority in the top of second member of Kongdian Formation is thin layer,affected by many factors,acoustic logging curve can ’t reflect the character of the reservoir effectively.In this paper,according to the geological characteristics and data of this area,using the quasi-acoustic which is based on the geology,log,seismic research and petrophysics,to analyse the sensitivity of the different borehole log,then choosing spontaneous potential and natural gamma ray well log which can reflect the lithology character effectively and applying the quasi-acoustic technology to reconstruct the curve of the reservoir character for well-log inversion.The results suggest that the method is effective in reservoir prediction and lithology identification.更多还原
