But in a little old-fashioned synthetically record well instrument software not providing the data interface, Be that its data to exterior procedure is the hideaway, the need of base expert gets the long-range data, and real time making the corresponding decision-making is extremely urgent! The article discusses the method of used the UDP broadcast technology realization between synthetically record well instrument and the field data terminal in the Well instrument data long-range transmission system，and describes the socket programming principle and the realization method of it . Has used VC++ and Delphi two kind of IDE in this system, have adopted DLL and Multi-thread technology to come to accomplish SOCKET communicating. And have introduced the need analysis , population design , detailed design and system testing of recording well instrument real time data transmission system that coming true under the environment owing to broadcasting communication pattern in Delphi and VC + + Visualization. Have realized the data transmission module、the datareceive module and some master data processing.
