基于电成像资料的砂体古流向识别及应用

Recognition and application of paleocurrent direction of sand body based on electrical imaging data

本文基于电成像资料及常规测井数据进行研究区的分析,利用电成像资料高纵向分辨率及有效研究砂体发育模式的优势,总结目的层岩性相的发育情况,并进一步归纳砂体古流向的判别方法。将该方法运用到区域X井后,其结果能与地质认识吻合良好,说明该方法能有效识别古流向,为勘探开发提供帮助。

This paper analyzes the study area based on the electrical imaging data and conventional logging data,and summarizes the development of the lithologic facies of the target layer by using the advantages of the high vertical resolution of the electrical imaging data and the effective study of the sand body development model,and further summarizes the discrimination method of the sand body ancient flow direction. After the method is applied to the regional X well,the results are in good agreement with the geological understanding,which shows that the method can effectively identify the ancient flow direction and provide help for exploration and development.
