The invention relates to an offshore drilling platform area seismic acquisition and observation system design method comprising the following steps: designing a conventional seismic acquisition and observation system of a work area, and determining conventional acquisition parameters; delineating a drilling platform range in the work area, performing compressed sensing seismic acquisition observation system design on areas except the drilling platform range in the work area by taking the conventional acquisition parameters as initial parameters, and determining compressed sensing acquisition parameters; performing conventional seismic data and compressed sensing seismic data simulation, and performing regularization reconstruction on the simulated compressed sensing seismic data; and performing error comparison on the regularized reconstructed data and the conventional seismic data, if an error requirement is met, outputting the current compressed sensing seismic acquisition observation system and compressed
