在超稠油的采过程中,日常的修井作业较多。修井前排液般通过套管排液,降低井底压力,进行不带压修井作业,但排出的稠油含砂量高,直接通过管线接入集油系统容易对系统管线造成损坏,甚至对处理站的稠油处理造成影响;另外,排出的原油容易喷溅在地面,造成井场污染。针对这现状,研制出种可以对对套管排液沉水、沉砂、回收的多功能装置。
In the super-heavy oil mining process, more daily workover work. Workover drainage through the casing before the liquid drainage to reduce the bottom hole pressure, without pressure workover operations, but the discharge of heavy oil sand content directly through the pipeline access to the oil collection system is easy to cause damage to the system pipeline, Even dealing with heavy oil processing station impact; In addition, the discharge of crude oil easily splashed on the ground, causing the well site pollution. In response to this situation, developed a kind of multi-functional devices that can drain the casing casing, sink and recover.
