Abstract

During the use of gas wells, the production time must be increasing. If reasonable measures are not taken for a long time, the bottom hole pressure will be reduced. If the gas flow in the gas well can no longer drive the water at the bottom to the ground, it will lead to the accumulation of water at the bottom of the well and produce back pressure, which will have a very obvious impact on the production of the gas well until the gas well finally can not meet the normal production requirements. This paper first analyzes the water production law and productivity details of shallow gas fields, then analyzes the diagnosis mode of wellbore effusion, and finally puts forward the practical application mode and strategy of drainage gas production technology, hoping to provide a reasonable reference for the optimal development of related work.
