    The trajctory parameters for horizontal drilling designed by use of seismic data include the horizontal target layer, segment the coordinates (x,y,z) of target points, the azimuthal angle (ot) and the dip angle (0) of the trajctory, and the horizontal trajctory curve. Two keys in designing the trajctory of horizontal drilling lie in the correct calibration for horizons, and the cautious study for velocity field. Based on the wavelet analysis on a set of 3-D seismic data in LHK area, the wavelet parameters for generating synthetic seismograms are extracted and the characteristic layers arc correctly calibrated with those high-quality syn-thetic scismograms. The features in velocity variation arc drawn from velocity analysis and a high precision velocity map and detailed structural map for the characteristic layer are plotted with the aid of an interactive workstation. The procedure for designing horizontal drilling is developed as a result of the work on the trajctory design of Well HD-1. Practice shows that this technique for horizontal drilling design is economic, effective and accurate.

    The wavelet analysis is a milestone in the development of Fourier analysis history. It is superior to the Fourier transforms due to its possession of good localization performances in both time and frequency fields. Since it can focus the analysis to any details, the wavelet analysis, known as mathematical microscope, is an important break--through inmethods and tools of signal analysis and processing.
