排水采气工艺是当前众多气田采气工艺中的一种,主要应用于有水气田的后期开采。随着气田的不断开采,气井内液体逐渐积累,需采取有效排水采气工艺,以免造成气田产效的下降。近年来,随着国际能源的日趋紧张,科学应对气田产水现象已成为国内外气田开采的重要课题。因此,对排水采气工艺进行研究,为有水气田提供决策依据具有重大现实意义。
Drainage gas production technology is currently a gas field in many gas production process, mainly used in the late exploitation of water and gas fields. With the continuous exploitation of gas fields, the liquid in the gas wells gradually accumulates, and an effective drainage and gas recovery process needs to be taken to avoid the decrease of the gas field production efficiency. In recent years, with the increasingly tense international energy sources, the scientific response to water production in the gas field has become an important issue for gas field exploitation at home and abroad. Therefore, it is of great practical significance to study the drainage gas production process and provide decision-making basis for water and gas fields.
