Three-component directional correction method of submarine node seismograph - Eureka

Embodiment Construction

[0071] Such as figure 1 A three-component orientation correction method for a seabed node seismometer shown, comprising the following steps:

[0072] Step 1. Layout of shot points and seabed nodes and acquisition of seismic wave data:

[0073] Step 101, setting multiple shot points on the sea surface, and using the source ship to excite seismic waves to the seabed at each shot point; wherein, the number of shot points is n trace one, n trace shot points are located on the same straight line, n trace The shot points are marked as the first shot point, the second shot point, ..., the h-th shot point, ..., the n-th shot point from front to back according to the running direction of the source ship trace shots, j′ and n trace is a positive integer, and n trace ≥3, 1≤h≤n trace ;

[0074] Step 102, laying out multiple seabed nodes on the seabed, the location of each seabed node is called a detection point; wherein, the number of seabed nodes and detection points is n, and n s...
