Oil well increasing oil device is one of downhole tool to make oil well stimulation. rod pump in the import section of the tail pipe is oil gas and water mixture back and forth cycle is relatively low-pressure area, thus resulting in the import of rod pump for liquid present instability. Especially energy shortage in the layer, pump rod sank less than a reasonable degree of sinking wells , instability is even more apparent. In the formation pressure , lack of capacity for the fluid case, the liquid product flow pattern changes, effective rod pump up the weak link for the solution to improve the liquid flow rate, pressure to make changes to accelerate the liquid flow capacity improve the coefficient of the pump is full , to increase pump efficiency increase production purpose.
