Study And Application On The High Resolution Seismic Acquisition Technology In Liaohe Basin

Liaohe Geophysical Exploration Company starts the research and studyt on the high resolution seismic acquisition technology in Liaohe Basin since 2000. Through years of theoretical research and field practice, a set of high resolution seismic acquisition technology with Liaohe character has been developed.This paper analysed the previous seismic data in Liaohe basin and the causes that affect the seismic data quality have been found. In order to raise the S/N ratio and the seismic data resolution, corresponding technological measures have been adopted according to different steps in the field seismic operations.Liaohe Geophysical Exploration Company has systematically studied and analyzed the tests and the application of the high resolution seismic acquisition technology carried out in Liaohe Basin and it has summarized a set of high resolution seismic acquisition technology suitable to Liaohe Basin, including delicate geomety design technology, high definition LVL technology,technology of optical deciding on the shooting lithological layer, geophone pattern receiving technology, selecting the types of geophones and instrument parameters based on the quality of reflection from the objective layer etc..Through its technological application in Liaohe Basin, good economic and acquisition results have been made. Recently, with the development of instrument and geophone technology. There is a high focus on the basic work. As per the increasing request for the exploration and geological task, there is much work to be done on the high resolution seismic acquisition.
