Abstract: The data transmission and production management of exploration and production in QinghaiOilfield always depend on microwave transmitter-receiver,which can not meet the demand of rapid exploration, blocking the transmission and intercommunion of information. In addition, field operation of oil-gas exploration features in high mobility, fixation communication systemis not set up,which making production management be not in time and lack veracity. Through the star communication network of VSAT Ku wave band was set up and linked with distance-controlled telephone network at the base, so as to realize the free communication between production unit field and management department at base, at same time, by using the information system of exploration production, it is realized that the specific data processing such as log profile along with drilling well, well logging curves, pla yback of log second data , real time data of log instrument, and oil-testing data , geophysica l da ta a s well a s web releasing function, with the geological data, the daily report of drilling well and oil-testing released onsite together, the dynamic information platform of exploration management has been established, which provides leaders a t various level, research personnel and managers with an integrated, abundant data, dynamic information platform along with drilling
