Abstract: Since development of Tahe oilfield that has converted from exploration, the available 3D seismic interpretation methods have not metthe demands of well arrangement precision in stage of petroleum development. Detailed calibration of seismic data and detailed interpretation ofstructures will be conducted as necessary. In this paper, new techniques at home and abroad such as multi-well composite calibration and 3Dvisible data correction, etc., are selected and applied. The results show that work efficiency of seismic interpretation can not only be improved,but also the accuracy of time-depth conversion and structure mapping be guaranteed, forming a set of technical methods for meeting interpreta-tion and mapping accuracies in stage of development.

Key words: Tarim Basin, 3D seismic interpretation, reflected wave, calibration, correlation, average velocity, accuracy
