Application of layer oil extraction pump
edit:keruitime:2012-12-27 browse:

 

recently, the layer oil extraction pump has a successful result, by the application for area 2, WC2-45 well in 3 Unit of Zhongyuan Oil Field. In Nov.26th, 2012, the layer oil extraction pump put down to the well. Nov.29th, 2012 becomes increase oil production. Until Dec.18th, 2012 this well increase 10 m³/day, increase 0.5t/day, hydraulic add up to 220 m³, oil production add up to 10t.Layering oil


 

As to enter the high water later development, area 2, WC2-45 well drive efficiency drops by year, useful oil layer worse. Part of the well has Lithologic property, fluid permeability difference, Heterogeneity is serious. Over years fill the hole and layer transfrom, multi-layers combined extraction and other construction, the layer contradiction Increasingly prominent. In order to solve influence from the layer interference to oil well, our company developed the layer oil extraction pump in 2012.


 

Layer oil extraction is to say that seal off the several interference oil layer with packer to realize layer extrction and have no interference to each other, and makes the lower pressure layer produce oil normally. It is composed of Φ44/57 layer oil extraction pump, self-sealing packer, compensator, tube centralizer, lift up joint. More details from

After construction, the effect of field application is very well. Layer oil extraction construction technology avoids the layer interference effectively and improves output. Has the same leading guiding significance to Similar oil reservoir, suggest to widely used for the badly interlayer interference area.
