Operation of gas wells under conditions of intensive carrying out of mechanical impurities

[摘要] The presence of a sand plug at the bottom hole of a gas well has a significant impact on its production capabilities, which entails a reduction in the gas production capacity throughout the entire field. To solve this problem, it is necessary to carry out timely measures to clean the bottom hole of the sand, and also to optimize the operating mode of the well so that not only to keep the gas production at the proper level, but to reduce the carrying out of mechanical impurities. The work of a gas well under conditions of sand plug formation was considered. Based on the two-term law of non-linear gas filtration to the well, a mathematical model of accumulation of a sand plug at the bottom was developed, which was consistent with the field data.
