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。
At present, the main source of energy is oil and natural gas. With the continuous downturn in the oil market and the increasing demand for natural gas in the market, the exploitation of natural gas has also become the mainstream of current oilfield development. However, with the deepening of gas field exploitation, prolonging the production time of gas wells, the oil casing pressure drops continuously and the carrying capacity of the gas wells decreases. When the gas well production is reduced to a certain extent, the wellbore fluid gradually forms, affecting the normal production. In view of the above situation, it is a technical problem that the gas field needs to be solved selectively to carry out drainage and gas production technology, drain the wellbore fluid, resume the production of gas wells and increase the recovery rate of natural gas.
