摘要
低渗透凝析气藏,在气井开发过程中,当地层压力降低到露点压力以后,凝析油会析出,积液造成地层污染,使气井产能下降。为此,对濮8-12井探索实施了注(甲醇段塞和N2)(干气)反凝析污染治理技术,解除其地层反凝析造成的污染,恢复了气井生产产能。
Low-permeability gas condensate reservoir, in the gas development process, the formation pressure is reduced to a dew point pressure after the condensate will be precipitation, fluid has caused pollution, which makes gas well productivity decline. To this end, pairs of PU8 - 12 methanol injection wells to explore the implementation of the technology, the lifting of condensate formation Key words：gas condensate gas reservoir; gas put; methanol cheaning slug and N2 （dry gas） anti-condensate pollution control anti-pollution, restoring gas production capacity.
