地层抑盐解堵工艺在高含盐油藏的应用

Stratum Salinity Plugging Process in the High-salt Reservoir

中原油田采油三厂部分高含盐油藏在开采过程中出现严重结盐,造成因生产管柱盐卡、盐堵而躺井和因油层盐埋而液面下降、供液不足,严重影响生产。地层解堵抑盐工艺技术解除含盐油藏地层结盐造成的油层堵塞,恢复或提高产量,克服清水洗盐造成的油层伤害、含水恢复期长和井筒加抑盐剂有效期短的问题,对恢复油井产能和减少躺井具有重要的意义。

Some of the high-salt reservoir in the Zhongyuan Oilfield Third Factory Appear Serious phenomenon of Salt,it lead production string clipping and blocking to the oil formation stopping,and lead the oil well being buried by salt to the liquid level dropping and lack of the liquid,it affect Seriously the production.Stratum Salinity plugging process removes stoppage of the oil formation by the application of high-salt reservoir being Serious phenomenon of Salt,restores and increases production,it overcome problems of the oil well being hurtted by the water washing salt,a long recovery period of oil content and a short period of Shaft plussing Salinity agent.It was the great significance to restore well productivity and to reduce the number of the wells lieing down.
