[Abstract]:Because of the low efficiency and high energy consumption of the surface oil production system, the oil production cost of the oil field enterprises is increased. According to the excellent speed regulation performance and the remarkable energy-saving effect of the frequency conversion speed regulation technology, this paper puts forward the viewpoint that the surface oil recovery system should be reformed. In order to eliminate the problem of power generation, achieve soft start, improve the system efficiency. The development of this topic is of great significance for oil field enterprises to achieve energy saving and efficiency gains. This paper is based on consulting the data of frequency conversion speed regulation at home and abroad. Combined with the present situation of the original surface oil recovery system, the calculation and energy consumption analysis of the recovery efficiency of the pumping unit well are carried out. The energy saving methods which have been widely used in oil fields and have achieved obvious results are compared and analyzed, and the frequency conversion speed regulation technology is put forward. Reactive power compensation technology and sensor technology to improve the surface oil production system, the feasibility evaluation and calculation of energy saving and production increase, it is concluded that this scheme can effectively reduce the power consumption per ton of oil, and realize the saving of energy and consumption. According to the reform scheme and system performance requirements, the overall design of the system and the design of related control hardware are carried out, and the movement of the power consumption equipment before and after the transformation is compared and analyzed. It is concluded that the system can meet the needs of high efficiency operation of oil wells under different reservoir geological conditions, combined with local special geographical environment factors, the system is applied on the spot, and the economic and social benefits are evaluated and analyzed. It is concluded that the system has strong reliability and adaptability, which can not only realize the soft start of the motor and intelligently adjust the parameters, but also meet the requirements of energy saving and increasing production. At the same time, this paper also points out the inevitable potential faults of the system itself. Through the transformation and application of the surface oil recovery system, it is found that the frequency conversion speed regulation technology has great application potential in oil field enterprises. It provides guiding direction and technical support for oil field enterprises to realize energy saving and increasing production.
