With the production information of seismic acquisition as an example, the author made a comparative analysis of the advantages and disadvantages between conventional input and fast input on the client of SINOPEC Exploration Production Management Information System (SEMIS4.0) and, through bypassing this input mode of the client, improved the input method of information, thus making up the shortage that the input mode of this system client is incapable of realizing the fast input for a great number of records such as surveying data of 3D seismic acquisition. With the improved input method, a great number of records such as surveying data of 3D seismic acquisition can be quickly inputted into the system, and time needed is greatly cut down.
