An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system
Deep Underground Science and Engineering, EarlyView.The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an
