地震检波器

COV gathers can also be constructed through selecting traces from different cross spreads of a 3D survey. A simple and practical way of constructing COV gathers can he described as that 1 when a dominant receiver line direction is determined, the inline offset and crossline offset of every trace can be calculated; 2 the inline offset and crossline offset ranges fruit; negative to positive for the whole dataset can be well represented by the range of the receiver spread of a typical source; 3 the full range of inline offsets can be divided into several sob ranges using twice the source line spacing and the full range of crossline offsets can be divided using twice the receiver line spacing; and 4 one sod; sob-range inline offset and one such sob-range crossline offsets form a COV gather.

一个简便实用的构造COV道集的方法是：在给定检波线的走向后，计算出每一地震道的inline炮检距和crossline炮检距；用观测系统中一个具有代表性的炮点的检波器排列范围来确定整个数据的inline炮检距范围和crossline炮检距范围，用两倍的炮线间距把inline炮检距的范围分成若干份，用两倍的检波线间距将crossline炮检距的范围也分成若干份，一份inline炮检距和一份crossline炮检距就构成一个炮检距向量道集。

Meanwhile, the high master frequency band signal acquisition channel makes full use of the cymoscope sensitivity and hardware dynamic range, has larger analog signals front-located gain, thereby reinforcing the signal-noise ratio of the high master frequency band signal, and bringing along benefits for the later stage high resolutions seismic data process.
