地球物理技术除了用于油气勘探之外,在油气开发过程中也起着重要作用。在过去的十几年来,时移地震已被证实可成功用于优化油田开发策略。最近,时移地震出现一个新的趋势——高频度油藏监测,即优化短期和长期油田管理。本文介绍了Shell为应对高频度地震监测如何降低费用所做的工作。比如在海上,可以通过新型检波器和更有效的地震船降低费用;在陆上,通过新观测设计、光纤DAS电缆、稀疏观测系统和可移动地下震源降低费用,减少采集脚印。
Geophysical technology plays an important role in the development of oil and gas except for oil and gas exploration. For more than a decade, time-shifted earthquakes have proven successful in optimizing oilfield development strategies. Recently, there has been a new trend in time-shifted earthquakes - monitoring of high-frequency reservoirs, optimizing short-term and long-term field management. This article describes how Shell is working to reduce the cost of high-frequency seismic monitoring. At sea, for example, the cost of new geophones and more efficient seismic vessels can be reduced; on land, the cost of acquiring new footprints is reduced through new observational designs, fiber optic DAS cables, sparse observing systems and mobile ground sources.
