Abstract：Some oblique short events often appear in narrow zones on CDP time section crossing structurally domed area, and some low velocity events follow the normal reflections on the far traces of single cover records.Identified by computations, all such events are considered as converted waves, which severely decrease S/N ratio of seismic records.The measure for eliminating converted waves is to use proper long spread and sufficient folds of multiple coverage in data acquisition, and to adopt 2D filtering after stacking and the method for eliurinating multiples in data processing.This measure proved highly effective.
