由于螺杆泵井具有独特的采油技术特点,目前它的应用在逐年的增多,螺杆泵投产时,电机多数按大泵井匹配大功率电机的原则,随着生产制度、工作参数的改变,这种匹配有一定的不合理性。对于大泵井转数低、产液量低的井仍然匹配大电机,就出现了大马拉小车的现象,无论从节能的角度出发,还是从精细管理的角度看,对于电机的匹配都应该有一个全新的认识。本文通过计算光杆扭矩、驱动头功率等一系列数据,寻找出最佳的电机匹配值,在保证螺杆泵井正常生产的前提下节约能源。
As the screw pump has a unique oil drilling technology features, its application is increasing year by year, screw pump put into operation, the majority of the pump according to the principle of matching large pumps and high-power motors, with the production system, the working parameters of such changes Matching has some irrationality. For large pump well rotation speed is low, the production of low-volume wells still match the large motor, appeared in the phenomenon of a large horse-drawn cart, both from the energy point of view, or from a fine management point of view, the matching of the motor should Have a new understanding. In this paper, a series of data such as polished rod torque, drive head power and so on are calculated to find out the best motor matching value and save energy under the premise of ensuring the normal production of the screw pump well.
