IMPROVEMENT OF ROD EQUIPMENT OF DEEP PUMPING UNITS IN THE CONDITIONS OF OIL FIELD DEVELOPMENT

Abstract

Currently, it is relevant to reduce the cost of maintenance, selection and purchase of fishing equipment, primarily deep-water pumps, tubing, pumping rods. After all, they are most susceptible to wear and the supply of the rod pumping unit depends on their condition. However, despite the well-known improvement of production technology introduced by manufacturers, there is a tendency not only to increase the service life of pumps, but also to decrease. The reason for the decrease in the service life of deepwater pumps is the continuous deterioration of their operating conditions. The reason for the decrease in the service life of depth pumps is the continuous deterioration of their operating conditions. It is established that this is due to an increase in the depth of discharge of pump compressor pipes (SCS), progressive wetting of well production, an increase in the corrosive properties of the pumped liquid, etc. The cause mentioned above in the article was solved in the following way, studying the consequences. The task of the proposed modification of the stand is to improve the design of the unit for testing rod pumps by changing the position of the pump drive and ensuring accounting for leaks through the plunger pair. The mechanism of mutual action of the plunger in the pump cylinder is solved by the fact that the internal channel of the plunger of the rod pump testing unit with a system for measuring and recording pump parameters is blocked, a pressure gauge with a high-pressure inert gas is installed on the pressure line. Modeling of fluid flow in the stand position was carried out. A plan of the experiment Matrix was drawn up and the minimum number of repetitions of the experiment was determined.The obtained experimental data were processed statistically. The obtained regression models were tested for statistical significance. Detection rates were more than 90% in all cases. It was found that during turbulent fluid flow, the amount of fluid leakage in plunger pairs with a constant microregion in the form of a right triangle is less than in smooth plunger pairs. The Reynolds number for quantitative experiments for each hole was carried out by changing the value of the constant viscosity, a given flow of liquid entering the hole of the plunger pair.
