At the end of the 2021 year, Shengli Oil Field completed the construction of a demonstration base for the comprehensive upgrading of pumping units in domestic upstream enterprises. Through the renovation of pumping units and wellhead installations, as well as the optimization of technology and power technology, the demonstration base 15 oil and water wells have realized “Unmanned pipe protection”. 

    Based on this successful experience, Shengli Oil Field will take this demonstration base as a template to formulate “Lean management construction code for pumping units”, which will be extended to other oil production plants. It is reported that in the upgrading and optimization of pumping units, Shengli Oil Field Adopts maintenance-free bearings and the maintenance-free period is extended from half a year to eight years; based on Permanent Magnet Motors, semi-direct-drive pumping units and direct-drive pumping units are used in some oil wells, cancels the belt and the gearbox system, enhances the transmission efficiency, the comprehensive electricity-saving 15% above. There should be linear motor, linear motor is a typical permanent magnet direct drive motor, and linear motor has been used in pumping units in practice, based on this, Shengli Oil Field transformation of the permanent magnet motor is likely to be linear motor. 

     The straight-line motor pumping unit uses the straight-line reciprocating motion of the straight-line motor directly to drive the pumping rod up and down, thus achieving the goal of lifting the liquid in the oil well, can Save 20%-40% power. 

    Kunshan Tong Mao Electronics Co. , Ltd. , self-developed and self-marketing Linear Motors, including non-core Linear Motors and linear motors with iron core two categories, are using European and American technical standards and processing technology, with high speed, high precision, high frequency response, long life and other advantages.
