%X The time-depth conversion,that converts the seismic data from the time domain to the depth domain,is a very important step in seismic processing,and it is the key to do seismic interpretation which indicates the oil and gas structures successfully.But the result of time-depth conversion depends on the accuracy and veracity of the velocity model building.After researching the geological characteristics and geophysical characteristics of the highly-steep structure in east Sichuan,the modeling method of velocity-controlling points is suggested,which uses the seismic reflective layers to be the velocity model controlling layers and uses the fault pointsoin both sides of the large fault to be the controlling points.It achieves great effect on improving the seismic mapping by this method.
