Abstract: Seismic technology achieved a great success in recent years, and has become a key method in oil and gas exploration. Now, seismic technology is focusing on oilfield development area. The new techniques mainly include 3-D seismic, vertical seismic profiling, cross-well seismic, 4-D seismic, multi-wave/multi-component seismic, micro-seismic monitoring and seismic while drilling. These techniques are paid more and more attention in the oilfields in China and have achieved good results in application, which significantly contributed to the increase of reserve and production. The paper reviews the forming process of seismic technology, introduces and summarizes the development seismic techniques, and discusses the developing trend.
