The metering and controlling of down hole flow has became an important and indispensable technology in the development of oil field as well as the intelligent oilfield technology, the correlative data which measured by them can provide a reliable theoretical basis for the production and management of the oil-field. Develops a new flow measurement device which can adapt to the complex down hole environment is very important. This paper emphasis on the composition of the data acquisition system about flow test in the down hole, including the design of data acquisition system, the application of bus, the selected of core chip and the design of software, and super-induce some collecting data that get in the test, determining the most value information, as well as making a more rapid response to the oil deposit management, gets up a significant guiding sense to the heavy oil development and the intelligent well completion.
