【摘要】 地震资料的极性确定是关系到井约束反演的重要问题，也是长期以来应用地震资料进行岩性解释及储集层预测时困扰我们的一个问题。70年代中叶以来，国外已有许多人对这一问题进行过研究，但在实际工作中仍存在着许多认识问题。作者根据多年的实践，从地震剖面的阻抗特征，结合测井（声波、密度及VSP测井）资料，总结出了一套判别地震资料极性的标准及一些辅助方法。此外，还介绍了一些做好井约束反演的实际经验，诸如地震相位角的消除、地层反褶积、目标处理、断层分段处理等。更多还原

【Abstract】 Polarity determination of seismic data is closely correlated with well restrain inversion, which often troubles us in lithologic interpretation and reservoir prediction with seismic data. Based on impedance characteristics of seismic profile and well logging (acoustic, density and VSP) data, the author summarized the standard and some auxiliary methods for determining polarity of seismic data. Furthermore, this paper presented some actual experimences for well restrain inversion such as elimination of phase angle, stratigraphic deconvolution, processing of inversion precision and segment processing of fault etc.更多还原
