摘要 目前能源的主要来源为石油、天然气,随着石油市场的不断低迷,市场对天然气的需求日益增加,天然气的开采也成为当下各油田发展的主流。但随着气田开采的深入,气井生产时间的延长,油套压不断下降,气井携液能力降低,当气井产量降低到一定程度时,井筒积液逐渐形成,影响了正常生产。针对以上情况,有选择性的开展排水采气工艺技术、排净井筒积液,使气井恢复生产,提高天然气采收率,是气田急需解决的技术难题。 Currently the main source of energy is oil and natural gas. With the continuous downturn of the oil market, the demand for natural gas increasingly grows, gas recovery has become the mainstream of each oil field development. But with the deepening of the gas field exploitation and the extension of gas well production time, oil casing pressure continuously declines, gas well liquid carrying capacity also reduces. When the gas well production reduces to a certain level, wellbore liquid loading gradually forms, which can affect the normal production. In view of the above situation, the suitable drainage gas recovery process should be used to drain wellbore fluid to restore the gas well production and enhance natural gas recovery.
