One of the factors decreasing the operation efficiency of wellhead pump unit is the fluid loss from the starting space between the pump, barrel coupling and the plunger. Due to the the pressure of liquid column rising within the barrel, as well as the friction wear over time, the space between the barrel-plunger pair increases, significantly amplifiying the fluid loss. The pressure within liquid columns on the inner and outer barrel surfaces should be aligned to prevent their widening due to the pressure. The space increases due to the hydrostatic pressure in the pumps in the upper parts of the barrel coupling, thus the fluid leakeage increases as well. In case, when the barrel coupling is in the lower part of cylinder, due to the pressure in the liquid column from within and outside, the space does not increase and as a result the well production rate rises for up to 3 %.
