产品描述

简    介:

 

 

深井抽油泵采用双层泵筒结构,上冲程时,管柱内的液柱静压力作用于泵筒外壁上,在该压力的作用下,泵筒与柱塞间的间隙减小,因而可减少因漏失而引起的泵效低;在下冲程时,由于内外压力的平衡,可消除胀泵现象,因此明显延长泵筒的疲劳寿命。独特的柱塞防卡设计,可有效解决机械杂质以及轻微出砂井中出现的卡泵问题。 

该泵主要用于地层供液不足和压力低等原因导致的常规举升工艺难以生产的稀油井,井深一般在26003500m之间。 

 

This pump applies double pump barrel structure, on the up-stroke, the liquid column static pressure within the string acts on pump barrel outer-wall, under the action of the pressure, the clearance between the pump barrel and plunger is reduced, thus can decrease the low pump efficiency caused by leakage; On down-stroke, due to the balance of internal and external pressure, it can eliminate the phenomenon of bilge pump, thus significantly extend the fatigue life of pump barrel. Unique design of plunger anti-stuck can effectively solve the mechanical impurity and slight pump stuck problems in sand producing wells.

This pump is mainly used for thin oil well which the conventional lifting technology cannot produce due to the insufficient formation fluid and low pressure causes, the well depth is commonly between 2600 ~ 3500 m.
