Compared with the past, the current smart phone can access the Internet, transmit documents, watch TV and chat with wechat. It has all the functions in hand. In oil field production, if an energy-saving motor has a complete set of functions such as the original well motor, reducer, electric control box, belt, etc., it can also be called the "fighter" in the motor. On April 22, the reporter learned from the engineering and technical team of the third oil production plant that they are carrying out the field test of the direct drive transformation of the permanent magnet composite motor of the beam pumping unit, which is to study the application effect of the "fighter" in the motor in the oil field production. The project is a company level test project, and it is also the first attempt to apply direct drive permanent magnet composite motor in the oilfield. At present, 9 wells have been tested. "The 9 pumping wells that we reformed are in normal operation. According to the current test results, the electricity saving rate of 100m per ton liquid is 20.8%, and the system efficiency is increased by 11.2 percentage points. " Liu Hongyu, the main participant of the project, said. In fact, for a long time, the oilfield has made a lot of efforts in energy saving and consumption reduction, and tried to use various energy-saving methods in energy saving of pumping units. For example, the third oil production plant has 3145 pumping wells, with an average system efficiency of 31.91%. The application proportion of energy-saving motors and distribution boxes of pumping units is 79% and 92.75%, respectively. Further energy-saving in energy-saving motors and power distribution boxes, the potential to improve the efficiency of pumping well system is very limited. How to further improve the system efficiency of pumping wells is a problem that technicians need to break through. "Since 2013, we have conducted a lot of research and conducted detailed analysis on energy consumption nodes of pumping wells. At that time, we thought that the energy consumption of the gearbox is also relatively large, but we have never tried to save energy in this aspect. At this time, direct drive permanent magnet composite motor came into our sight. Our team put forward the application of direct drive permanent magnet composite motor, the cancellation of pumping unit gearbox, the realization of the transformation of direct drive pumping unit, to further improve the energy saving effect. " Liu Hongyu said. After all preparations are made, the technicians "operated" in well 2-361-20, north of oil production team 1, No. 2 mine, No. 3 oil production plant, and removed the motor, reducer, electric control box, belt, brake, etc. of the original well, and installed the direct drive permanent magnet composite motor. For the first time, the "fighter" in the motor has been put into the field test. What is the application effect? "The daily power consumption of this well is 182 kwh with ordinary motor, and 148 kwh with direct drive permanent magnet composite motor installed. Compared with the ordinary motor, its comprehensive power saving rate is 21.2%, which saves about 23 yuan per day and 4400 yuan per year. Compared with other energy-saving motors, its power-saving effect is also obvious. " Liu Hongyu said. It is understood that the reformed pumping wells not only achieve the goal of energy saving and consumption reduction, but also the oil production workers no longer need to replace the lubricating oil of the gearbox, no longer need to replace the belt and adjust the four points and one line. At the same time, the fault points of the pumping wells are reduced, which can achieve maintenance free and greatly reduce the maintenance cost and workload. This year, they plan to reconstruct 20 pumping wells, further track the "postoperative" situation of pumping wells, summarize the test results, and lay a good foundation for further promotion. |
