用于海洋地震采集的方法和设备
摘要：
本发明涉及一种用于海洋地震采集的方法和设备，其描述了一种用于改善地震采集系统中的方位角分布的方法和系统。勘测采集系统包括由多个海洋地震拖缆船舶拖带的多个海洋地震拖缆和由多个源船舶拖带的多个源，多个海洋地震拖缆船舶包括第一海洋地震拖缆船舶和第二海洋地震拖缆船舶。多个海洋地震拖缆船舶和多个源船舶相对于彼此配置，以使得多个源船舶位于第一海洋地震拖缆船舶的一部分后面的一个或多个预确定纵测线距离处，并且还位于第二海洋地震拖缆船舶的一部分前面的一个或多个预确定纵测线距离处。多个海洋地震拖缆船舶和多个源船舶还在横测线方向上彼此隔开。
摘要（英）：

Methods and systems for improving azimuth distribution in a seismic acquisition system are described. A survey acquisition system includes a plurality of streamers towed by a plurality of streamer vessels, including a first streamer vessel (202) and a second streamer vessel (204) and a plurality of sources towed by a plurality of source vessels (206, 208, 210). The plurality of streamer vessels and plurality of source vessels are configured relative to one another such that the plurality of source vessels (206, 208, 210) are positioned at one or more predetermined inline distances behind a portion of the first streamer vessel and are also positioned at one or more predetermined inline distances in front of a portion of the second streamer vessel. The plurality of streamer vessels and plurality of source vessels are also spaced apart from one another in a cross-line direction.
