Applications of seismic acquisition technology in oilfield development and discussion on relevant problems
地震采集技术在油田开发中的应用及相关问题探讨

With deep exploration and development in old oilfields, it is more and more difficult to explore and develope the hydrocarbon resources, which becomes an obvious characteristic of the Liaohe oilfield that terraneous complex small faultages and secluded lithology traps are its main reservoirs. At present, the difficulties faced by oilfield development are deep, hidden, low, small, which means exploration layer is deeper, exploration target is more hidden, the proportion of low permeability and ultra-low permeability reservoir are more, and the scale of each exploration target is getting smaller and smaller. Based on current domestic and international seismic technology status, there are two effective ways to solve these problems: one is high-density seismic exploration technology, the other is to develop seismic technology, which includes cross-hole seismic, multi-component seismic, VSP logging and four-dimensional seismic technology. This article describes some recent applications of seismic technology to oilfield development. Meanwhile, it analyses the idea of developing seismic technology for oilfields in the Liaohe exploration region in the future.
