OBN全称Ocean Bottom Node，简称海底节点，它是一种位于海底，可以独立采集、记录地震信号的多分量地震仪。 OBN地震勘探. 海底节点. “海底节点”就是一个个独立的检波器，它既摆脱了电缆的束缚，又能够在海底灵活部署，定位更准，采集的数据质量更高。 . 补充 | 知识. 常规地震勘探采集的是纵波数据：垂向入射到检波器的地震波（简称单分量）。 OBN既可以采集多方位的数据：垂向纵波、水平方向转换PS波、垂向的标量压力波（多分量）。 海底多分量采集示意图. 早在上 …

2017年5月4日 · Ocean bottom acquisition is a marine seismic acquisition approaches popular in the latest decades. In ocean bottom acquisition, receivers can be either ocean bottom cables or ocean bottom nodes. Ocean bottom cables are usually positioned by receiver boat, while ocean bottom nodes are completely free positioned in deep ocean bottom.

2021年8月9日 · Ocean bottom node acquisition (OBN) is one of the technologies used to assist in deep marine exploration and development. It has allowed seismic acquisition over areas with islands and more complex shallow and deep bathymetry.

Ocean bottom node (OBN) acquisition is adaptable to more challenging imaging objectives providing full azimuth 4C sampling. PXGEO provides a range of ocean bottom nodes suitable in water depths up to 3,000 meter using efficient and accurate placement methods.

OBN全称Ocean Bottom Node，简称海底节点，它是一种铺设于海底，可以独立采集、记录地震信号的多分量地震仪。 随着海洋油气勘探目标日益复杂，以OBN和OBC（Ocean Bottom Cable，简称海底电缆）为代表的海底地震（Ocean Bottom Seismic，简称OBS）采集技术得到迅猛发展。

2018年10月25日 · OBN 全称Ocean Bottom Node，简称海底节点，它是一种位于海底，可以独立采集、记录地震信号的多分量地震仪。 海底节点地震观测方法就是将地震仪通过水下机器人直接布放在海底，地震仪自备电池供电，震源船单独承担震源激发任务。

2021年2月20日 · 海底节点 (OBN)在有效弥补拖缆地震 (TS)的勘探盲区、提供多波和宽方位角数据、定点和重复性等方面具有优势,成为海洋地震勘探的新技术方法.近十年来,OBN勘探技术和装备得到了快速发展,节点地震仪的性能进一步被优化,海底工作的时间和水深得到大幅度提升;智能自动化节点地震勘探系统走向实用,显著地提高了采集工作效率;针对OBN资料的特点,目前已研发了位置校正、上行/下行波场分离、镜像偏移、PS波成像与速度建模等处理方法,提高了成像品质,推动 …

Ocean Bottom Node (OBN) data, and sparse OBN, is ideally suited for Dynamic Matching Full Waveform Inversion (DM FWI). The processing toolkit for OBN includes 3D curvelet, sparse tau-p, and 3D fk domain algorithms, along with dedicated receiver domain-based deblending routines.

To overcome the limitations of OBN, this paper develops a Ocean Bottom Flying Node (OBFN) that combines OBN and AUV techniques. The proposed OBFN retains all the advantages of OBN systems, while at the same time can provide dramatic time and cost savings for ocean bottom seismic operations.
