2014年下半年以来,国际油价持续低迷,国际石油公司大幅度削减资本支出,全球勘探开发投资也相对减少,油气勘探开发逐渐向天然气、非常规、复杂储层、深海、极地、山前带等复杂区域转移,促进了地震勘探技术的不断进步。本文总结了目前世界上最先进的地震勘探技术前沿信息,通过对陆上、海上及海底地震数据采集技术和地震数据处理与解释技术进行梳理,总结归纳了包括宽频可控震源技术、百万道地震数据采集系统、海上拖缆采集技术、海底节点采集系统、偏移成像技术和全波形反演技术在内的6项目,国外最先进的地震勘探技术的应用新进展,为应对低油价降低勘探成本,节省投资,提供了一定的借鉴。
Since the second half of 2014, the international oil prices have been in a downturn. International oil companies have drastically reduced their capital expenditures and their investment in global exploration and development has also decreased. Oil and gas exploration and development have gradually shifted to natural gas, unconventional and complex reservoirs, deep-sea, polar and piedmont zones The transfer of complicated regions has promoted the continuous progress of seismic exploration technology. This article summarizes the most advanced seismic exploration information in the world. By combing seismic data acquisition and interpretation techniques of onshore, offshore and seabed seismic data, this paper summarizes the technologies including broadband vibrator technology, Seismic data acquisition system, maritime towed cable acquisition technology, submarine node acquisition system, offset imaging technology and full waveform inversion technology, 6 projects, the most advanced application of seismic exploration technology abroad, in response to low oil prices to reduce exploration Cost, save investment, provide some reference.
