油井堵塞问题一直制约着油井的正常生产,锦州采油厂从建厂以来一直使用机械解堵类技术对中低渗稀油油藏进行解堵,解除近井地带污染,恢复油井产能。经过多年现场试验,根据投入产出对比现场应用效果,优选和改进适合锦州采油厂的解堵技术,从而实现油层改造,解决油层污染,恢复油井产能。
The blockage of oil wells has always restricted the normal production of oil wells. Since its establishment, Jinzhou Oil Production Plant has been using mechanical unblocking technology to unblock medium and low permeability thin oil reservoirs, relieving the pollution of near-wellbeds and restoring oil well productivity. After many years of field tests, according to the field application effects of input-output comparison, optimization and improvement of the plugging technology suitable for Jinzhou Oil Production Plant, so as to realize the oil layer reconstruction, solve the reservoir contamination and restore the well productivity.
