深井抽油泵
簡??介:??深井抽油泵采用雙層泵筒結構,上沖程時,管柱內的液柱靜壓力作用于泵筒外壁上,在該壓力的作用下,泵筒與柱塞間的間隙減小,因而可減少因漏失而引起的泵效低;在下沖程時,由于內外壓力的平衡,可消除脹泵現象,因此明顯延長泵筒的疲勞壽命。獨特的柱塞防卡設計,可有效解決機械雜質以及輕微出砂井中出現的卡泵問題。?該泵主要用于地層供液不足和壓力低等原因導致的常規舉升工藝難以生產的稀油井,井深一般在260

深井抽油泵采用雙層泵筒結構,上沖程時,管柱內的液柱靜壓力作用于泵筒外壁上,在該壓力的作用下,泵筒與柱塞間的間隙減小,因而可減少因漏失而引起的泵效低;在下沖程時,由于內外壓力的平衡,可消除脹泵現象,因此明顯延長泵筒的疲勞壽命。獨特的柱塞防卡設計,可有效解決機械雜質以及輕微出砂井中出現的卡泵問題。
該泵主要用于地層供液不足和壓力低等原因導致的常規舉升工藝難以生產的稀油井,井深一般在2600~3500m之間。
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.
