Sand is a frequent visitor for oil recovery. Some oilfields have high cut, some have a low cut. But no matter how much content the sand takes, we could never ignore its influence during oil production. So what influence will the sand exactly bring to us? The following are just some example:
1).The sand will increase the abrasion of the barrel, plunger, standing valve, and traveling valve, which will greatly reduce their service life.
2). The sand in the clearance between barrel and plunger will result in stuck or scuffing on the barrel and plunger, greatly reducing the pumping efficiency.
3).Sand will bury the sucker rods when stopping the pump. It will cost us a lot of operation time.
From above 3 items we can see, sand can really bring a lot of harm to our equipment, pumping efficiency, and operation time. For now, there are a few technologies about how to solve the sand problem during oil production, like adopting a hydraulic jet pump to flush out sand, mechanical anti-sand technology, and chemical anti-sand technology. Today, I would like to introduce special downhole pumps to you developed by Sanjack. Hope they can help you get an idea about how a downhole pump can control sand during production.
