地震方法技术在油气勘探开发中的应用与挑战

Applications and challenges of seismic techniquesin oil-gas exploration and development

地震方法技术在过去几十年的油气勘探开发中起了非常重要的作用 ,目前最新进展具有六大特点 ,主要是向四维地震和虚拟现实研究方向发展。地震方法技术仍面临严峻的挑战 ,导至成本增加的十大实际问题急待解决。这 10个问题按地震方法技术的作用分为与构造性质和与油藏性质相关两大类。在未来 10多年内 ,地震方法技术最可能进步的有 10个新领域 ,其中动态油藏描述是地震方法的新任务 ,新一代地震数据采集和处理技术 ,数据、知识以及多学科的真正结合将是未来发展的重要领域。

Seismic techniques have played an important role in oil and gas exploration and development for decades. The advances of seismic techniques were made mainly in six aspects, particularly in 4 D seismic and virtual reality. However, seismic techniques face severe challenges. There are ten most challenging problems that control exploration cost to be solved. These problems can be classified as structure related and reservoir related. The paper lists ten areas that will be the most possibly ones to make breakthrough in the next ten years. Among them dynamic reservoir description, new generation of seismic acquisition and processing techniques, and integration of data and knowledge of multidisciplines, are of the most important areas.
