The invention discloses a method and a device for realizing a towing exploration control network, and relates to the technical field of offshore oil seismic exploration. The method includes the steps: initially designing a towing exploration control network form; converting node positions in the initially designed towing exploration control network into coordinates under the same coordinate system; performing network adjustment calculation for nodes according to the converted coordinates to obtain positioning precision distribution of the nodes in the towing exploration control network; adjusting the owing exploration control network form when calculated node positioning precision cannot meet operating requirements until node positioning precision of the adjusted towing exploration control network form meets the operating requirements. The technical scheme solves the problem that a current towing control network datum node is laid only by depending on experience, and node positioning precision of the towing control network cannot be evaluated before operation.
