海上勘探固体拖缆技术的研究与应用
|
摘要
固体拖缆降低了由于天气变化涌浪波动引起的背景噪音,扩大了地震采集作业时窗;不会因拖缆外套局部受损而造成海上采集作业中断,避免了因破损漏油造成的海洋环境污染;整条拖缆比重均匀,拖缆平衡易于调整。中海油田服务股份有限公司研制、开发了海上地震勘探固体拖缆,并对固体拖缆进行了生产试验。试验结果表明,固体拖缆性能指标符合要求,用其获得的采集资料满足采集生产技术的要求。
Solid streamer can not only reduces background noise caused by fluctuations due to weather changes,but also can expand the time range of seismic data acquisition,There is no disrupt to marine acquisition operation caused by the streamer damage,and the pollution to marine environment from oil leakage can be avoided.The streamer′s balance is easy to adjust for uniform proportion of the whole streamer.China offshore Oilfield Services Limited researched and developed a kind of solid streamer for marine seismic exploration.Production test are done to this streamer and the results showed that performance of solid streamer can meet the production requirements and the data requirements too.
