发明名称 Sucker rod guide
摘要 An oil well sucker rod guide protects the rods and production tubing from frictional wear during the vertical reciprocation pumping action. The guide has a sleeve enveloping the sucker rod with raised ribs contacting the tubing in an opposed fashion. The raised ribs are circumferentially sequenced to contact the entire circumference of the tubing and provide oil flow-through passages between the sleeve and the tubing. The raised ribs have side and inside end walls angled and contoured to increase through-put of oil in the tubing.

主权项 1. A guide for a sucker rod reciprocating in a well production tubing, the guide comprising: a cylindrical sleeve having a lengthwise concentric passage therethrough; and a plurality of ribs extending radially outwardly from said sleeve, each of said plurality of ribs having a circumferential outer surface, said surfaces taken together defining a common cylinder substantially congruent with an inner circumference of the production tubing, and having sidewalls co-operable with said sleeve and the production tubing to define flow paths for passage of well product between said sleeve and the production tubing during reciprocation of the guide in the production tubing; at least one of said ribs having interior end walls inclined at an acute reverse angle to increase a rate a flow of the well product through the guide.
