“…To restore the natural permeability of PFZ in low-permeability reservoirs it is advisable to use swabbing with additional use of downhole hydraulic generators combined with swabs. A relatively simple and efficient method of vibration swabbing is the method developed at VNIITneft (one of the authors of this work) for generating HDW using the GDG-14 hydrogenator consisting of two elements (swabs [11,12,13,14] or identical plugs for cementing casing strings), between which a spring is additionally installed. The prototype of the method is the known effect of pulsed loads during hard braking of railway trains.…”

The paper considers the influence of crank radius change on pumping unit kinematics during the dynamic fluid level control between tubing and casing in order to reduce the string fault rate. To improve the quality of prediction of these factors, the calculation of the movement of the polished rod over time is carried out using the Fourier variable separation method: the product of the balance bar head of a pumping unit defined as the movement of the slider of the pumping mechanism (in a straight line – like the chords of a circle), and the difference of such a chord with the length of the circle section equivalent to the movement of the articulated joint of the balance bar with the connecting rod. As a result, the accuracy of calculations is improved and the solution of the problem is simplified.

Nowadays deterioration of productivity and intake capacity of wells cause different problems in exploitation of oil and gas fields. It happens because of some irreversible physicochemical processes in the bottomhole formation zone: swelling of clay materials, colmation, formation of stable emulsions, confluence of salts, iron oxides etc. Various methods and technologies are used to solve these problems. However, they have disadvantages, for example, material and energy intensity, short-lived equipment, technological complexity. The method of pulse action by various vibrations seems to be the most effective solution. Vibrations are mechanisms that create controlled fluctuations of the working body influencing a recycled material and a reservoir. Now they are widely used in different industries.
