OIL OF DISTRIBUTED OILFIELD BASED ON GPRS NETWORKS ABSTRACT To solve problems of crude oil measurement and loss in distributed oilfield, a crude oil measuring and antitheft system is designed based on GPRS wireless work in the paper. In the system, a lot of problems existing in distributed oilfield for a long
