摘　　要：分析准噶尔盆地南缘“双复杂”区速度研究方法存在的问题,据研究区地质和速度资料特点,改进速度校正方法。以三维复杂构造实体模型为基础,开展井震联合层速度校正、全层系层速度反演。通过频率域融合井震联合校正速度和反演层速度优势,直观地体现了层速度在空间上的变化,为“双复杂”区圈闭落实及钻前压力预测提供可靠的速度基础资料。This paper analyzes the problems and shortcomings of the current velocity research methods in the"double complex"area in the southern margin of Junggar basin.According to the characteristics of geological and velocity data in the research area,the interval velocity correction method is improved,based on 3D complex construction solid model,the research promotes the velocity correction of well seismic joint formation,inversion of whole formation velocity.By fusing the advantages of well seismic joint correction velocity and inversion interval velocity in frequency domain,it di-rectly reflects the change of interval velocity in space,and provides reliable basic velocity data for trap implementation and pre drilling pressure prediction in"double complex"area.
