The recognition of sequence boundaries is a key problem in sequence stratigraphy.Core,seismic data, palaeontologic correlation and logging data are often applied to recogn ize sequence boundaries.In sparse well pattern, because of the limitation of seismic resolution and the length of the cores,a lot of logging data are needed in order to improve the recogn ition accuracy of sequence boundaries.On the basis of identifying the sequence boundaries of Zhujiang Formation in Pearl River Mouth Basin by diferent methods,such as shape of natural gamma-ray logging curves,acoustic travel time and wavelet analysis,a method for recognizing the sequence boundaries by making full use of well logging information in sparse well pattern is put forward.
