The device works well all the time.The device is divided into three zones:the zone for gathering gas,the zone for dehydrating and the zone for injecting.Here introduce the process how these three zones work.Here put emphasis on testing technique parameters of the device in the zones for dehydrating and injecting under the steady work condition and the best work scale;recording the running parameters of each device;comparing device’s simulation numerical values in each unit, equipment and technical process with actual measured numerical value;discuss if the device work in best condition depending on calculating the material’s balance and analyzing the factor impacting efficiency;and seek the disadvantages of the device on work and propose opinions. Drawing a conclusion after discussing the device with the data collecting from the work and comparing to standard:each operation parame
