    摘要： Seismic node systems can be configured for acquiring seismic sensor data with an array of seismic receivers or nodes deployable in a survey area, each receiver or node having a seismic sensor for acquiring the seismic sensor data, a clock, a controller and local memory. The seismic sensor can data characterize a seismic wavefield proximate the seismic receivers in the survey area. Quality control data can be generated based on the seismic sensor data and associated timing information provided by the respective clock, and incorporated into a seismic data flow for recording in the local memory.

    摘要： A system is proposed for conducting efficient marine seismic surveys in different climatic conditions for water depths of 0-500 meters, in near-shore zones and on the land for obtaining seamless profiles. The system includes at least one bottom module (BM) and onboard devices located on a vessel. The BM can be submerged from the vessel onto a bottom ground and lifted up on the board. The BM includes a case provided with roundings on its upper surface and its bottom area, to which case are mounted damping elements, a hydrophone and a geophone block for receiving seismic data, a vacuum port, a hermetic electrical socket, and equipment arranged inside the case, including—a clock generator,—a digital compass providing angle data,—an interface board essentially reading the seismic and angle data and transmitting thereof to the onboard devices, and—a recorder board communicating with the geophones, hydrophone, and interface board.

    摘要： A standard acquisition system is selected, the system comprising seismic signal sources disposed on an excitation surface and seismic signal receivers disposed on an acquisition surface, and specifying a fold number. A bin size is selected for a reflecting boundary, and the reflecting boundary is broken down into bins with the selected size. Ray tracing from each seismic signal receiver to each bin at the reflecting boundary and elongating of a reflected ray from the reflecting boundary to the acquisition surface are performed by computer simulation. A density of the seismic sources at the excitation surface is calculated using a computer program. Then, based on the calculated seismic signal source density, the seismic sources are disposed at the excitation surface for the selected seismic acquisition system providing the specified fold number.
