4C OBC深海地震采集系统技术发展

Technical development of 4C OBC deep ocean seismic acquisition system.

海洋地震技术从漂缆发展2C OBC,再到深海4C OBC。多波多分量及4D油藏地震、开发地震技术在近年取得了许多技术上的发展。本文介绍了目前世界4C OBC的市场发展状况及其采集系统的发展趋势和海洋物探服务公司选择4C OBC系统的考虑因素。

Ocean seismic technology has developed from streamer to 2C OBC and again to deep sea 4C OBC. The multiwave, multi-component and 4D reservoir seismic exploration and development seismic technology have achieved many progresses. The paper introduced the currently developed situation of 4C OBC market in the world and developing trend of its acquisition system as well as the considered factors when the ocean geophysical service company chooses 4C OBC system.
