胜利油田滩浅海地区地震勘探技术

THE APPLICATION OF SEISMIC EXPLORATION TECHNIQUE TO THE BEACH AND SHALLOW SEA AREA OF THE SHENGLI OILFIELD

滩浅海地区由于特殊的地表条件和复杂多变的表层结构,既不同于陆上勘探也不同于海上勘探,尤其在两栖地带存在海陆2种施工方式。笔者对滩浅海地区地震勘探的激发震源、检波器和观测系统等野外采集各环节进行了系统研究,提出解决滩浅海地区野外难以采集到高品质地震资料问题的方法,开展了地震记录上的干扰波压制、差异校正等方面的深入研究,形成一整套适用于滩浅海地区油气资源探查的高精度实用性的特色技术,取得了较好的地质效果。

Due to the specific surface conditions as well as the complex and varied surface structure of the beach and shallow sea area, the exploration work in such an area is different from beth continental exploration and sea exploration. In the amphibian zone, in particular, there exist two working means （sea and continental means）. Based on a systematic study of such field collection links in the field as the excitation seismic source, the detector and the observational system, the authors put forward the method for solving the difficult problem of collecting high-quality seismic data. On the basis of a thorough investigation into the interference wave suppression and the difference correction, a complete set of high-precision and practical special techniques for oil and gas exploration in the beach and shallow sea area was developed, and the results show that its geological effect is satisfactory.
