摘要
气井产层水堵是一种普遍现象,尤其是开发中后期或遭受外来液体侵入的气井则更为严重。产层水堵将降低气井产量,生产条件恶化,甚至造成气井停产、复产困难,采收率下降。为此,针对这一问题开展了室内评价和解除地层水堵药剂的研制,并进行了现场解堵施工,取得了显著效果。这为解除气井产层水堵提供了工艺手段,工艺有效期在12个月左右。
Blocking of pay zones by water often occurs in gas producers, especially during the middle-late development stage or when the producer is invaded by coming fluid. It is seriously detrimental to well deliverability and production conditions, even worse to kill the producers. To solve such those problems, a study was carried out on laboratory appraisal and development of de-plugging agents. The field operation results of this technology showed favorable effect. The effective lifetime of this method will be about 12 months.
