__ Even Wall Thickness Hollow Rotor For Downhole PC Pump * Well washing through hollow rotor; * Steam injection into well through hollow sucker rod and hollow rotor; * use of same components of sucker rod pumping system for both pumping and injecting. * The system requires the drilling of only one well for injection. * The injected steam builds up a steam chamber that rises to the top of the reservoir. * While steam injection heats up the oil and improves the flow characteristic, hot oil drains into the production well. * Huge cost savings because of material saving,price is 1/3 lower compared with solid rotor. -- Subscription Reminder: You're Subscribed to, EvenWall Using the address: gcc-bugs@gcc.gnu.org From: evenw...@hawne.com Wuhan EvenWall Machinery Co., Ltd.
