Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0024] At present, most oil fields mainly use pumping wells for oil production. The long-term production pump efficiency is low, and there are many sand wells. Bump pump is an important method for us to improve pump efficiency. Bump pump is to artificially cause the collision between the deep well pump piston and the fixed valve cover, timely eliminate the debris adhered by the wax of the deep well pump valve ball, and restore the production capacity of the oil well. Due to the current production of long stroke and slow stroke working system, and the long reserved light rod for heavy oil production, the donkey head will be hung, resulting in abnormal production. Therefore, the light rod reserved for most oil wells is short, and the light rod cannot touch the pump at the bottom of the well. The production site can only use the crane to cooperate, unload the donkey head load and collide 3-5 times. If the road is muddy in the rainy season, the crane cannot enter the well site normally, which seriously affects the production time of the oil well, and then affects the oil well production. Normal crane bump pump requires 4 people to operate, and it takes about 1 hour to complete the bump pump operation, which is labor-intensive and costly.

At present, the light rod 1 of the oil well is relatively short, and the light rod 1 cannot hit the oil pump at the bottom of the well. The production site can only use the crane to cooperate, unload the donkey head load and collide 3-5 times. If the road is muddy during the rainy season, the crane cannot enter the well site normally, which seriously affects the production time of the oil well, and then affects the oil well production. Normally, it takes 4 people to operate the crane to bump the pump, and it takes about 1 hour to complete the bumping pump operation, which is labor-intensive and costly.
