After years of development

some wells in South Yanchuan coalbed methane field have entered the decline period

and the daily liquid production of most wells has gradually decreased. Therefore

it is about to face the impact of intermittent pumping on productivity and production management. By studying the seepage mechanism of CBM

the non-destructive intelligent intermittent pumping technology is adopted for low-yield liquid wells with different well conditions. Considering such factors as downhole pressure gauge

peak and valley electricity price of municipal electricity

depth of downhole pocket

safety risk of remote pumping unit and so on

the implementation of unattended intermittent pumping without affecting the stable production of gas wells reduces the intensity of drainage and production well management

improves the efficiency of fine management

and has higher popularization value.
