Abstract

Abstract:

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.

Key words: CBM, non-destructive, intelligent, intermittent pumping, PLC
