Abstract: As a dominant technology for oil and gas exploration and development, geophysical technology plays an important part in oil and gas exploration and development. With oil and gas exploration continually unfolding, the areas of oil and gas abundance have been basically covered with 2D and 3D seismic survey lines. However, the 3D coverage rate of the royalty blocks remains low. The 3D coverage rate is less than 22 percent for the eight main onshore basins. With the seismic processing and interpretation technological development, the acquisition data acquired in the past are unable to meet the need for pre-stack depth domain processing and pre-stack reservoir prediction owing to the limitations of technology and equipment. It is necessary to strengthen the strategic seismic study of the replaceable and potential areas under the background of focusing exploration efforts on low-permeability, deep-layer, offshore and non-conventional areas. The healthy development of oil and gas exploration and development calls for more efforts for seismic coverage study and application of seismic technology in the initial stage. Based on the analysis of the current issues existing in application of seismic technology, this paper comes up with the suggestions to strengthen seismic coverage study, increase the investment for initial strategic study and beef up processing of the targets in old data.

摘要： 物探技术是油气勘探的主导技术，在油气勘探开发中发挥着重要作用。随着油气勘探不断深入，富油气区带已基本实现二维和三维地震全覆盖，但矿权区块三维地震覆盖率还较低，陆上八大盆地的三维覆盖率不足22%。随着地震处理解释技术的发展，以往采集的资料受技术和装备手段限制，不能完全满足叠前深度域处理、分方位处理及叠前储层预测等技术的需要。在常规油气勘探深化挖潜，并不断加大“低、深、海、非”领域勘探力度的转型期以及低油价背景下，针对接替领域和潜在领域的战略性研究地震部署需要加强。加强地震部署研究，加强地震技术前期应用研究，是油气勘探开发良性发展的保障。通过剖析目前地震技术应用存在的问题，提出了加强地震部署研究、加大战略性前期研究的地震投入、加强老资料目标处理的建议。
