Modern trends in the development of technology are based on the need for experimental studies of the equipment being developed in laboratory conditions with the maximum approximation of the operating modes to real ones. Such studies are impossible without the development of specialized stands with test automation systems. Automation of processes involves the organization of measuring channels as part of a stand using analog-to-digital conversion (ADC), digital-to-analog conversion (DAC), digital-todigital conversion (DDC) and the development of a hardware-software complex (HSC) based on high-speed computing devices. As part of the project to create new high-tech equipment, the specialists of FSBEI HE “KSPEU” and JSC “ChEAZ” developed and created an experimental stand designed to verify and confirm the correctness of the selected structural and circuit solutions used in the design of a synchronous valve electric motor (SVEM) and rod control station borehole pumping unit (RC SBPU). The object of experimental research was the prototype and prototype electric drives of oil pumping units, as well as their components: SVEM and RC SBPU. The article discusses the ways of organizing the measuring and control channels of the measuring and information system of the experimental bench, which allows to study samples of synchronous valve motors and control stations of the sucker rod pump unit in the regimes that are as close as possible to real field conditions simulating the operation of the oil pumping unit of the sucker rod pump unit. Thus, in the experimental stand, analog, discrete and digital control and control channels are implemented.

As it is known, currently, the fields at the last stage of development are operated predominantly with sucker-rod pumps. Their operation is usually carried out in quite complicated technological and hydrodynamic conditions dramatically affecting the operation efficiency. Based on the actual field data, the paper studies the possible impact of the depth of sucker-rod pump running on the delivery rate, which is one of the indexes of operation of the whole sucker-rod pump unit. The values of delivery rates by oil and water have been calculated and their functional dependencies on the depth of sucker-rod pumps running developed as well. The results justified the increase of delivery rate by oil and its decrease by water in reviewed value diapasons. Mathematical models of developed dependencies have been obtained as well. As a result of conducted studies, the practicability of the increase of pump setting depth in operation conditions of reviewed field is justified.

Abstract SCADA optimization platform is implemented to monitor and evaluate well performance. For Sucker Rod Pump, SCADA Optimization Software can be used to monitor the unit balance and gearbox torque. In some ways, not all required well configuration data for SCADA Optimization Software to do a calculation of counterbalance torque (CBT) for pumping unit balance and gearbox torque evaluation are available. Standard field Counterbalance Effect (CBE) measurement might be performed to calculate the CBT value. However, this standard procedure is limited to well that run on balance condition. For well with unbalance condition, the measured CBE needs to be adjusted by a correction factor which the equation will be presented in this paper. The corrected CBE value from the new equation is then inputted to the SCADA Optimization software to perform day-to-day real-time monitoring of pumping unit balance and gearbox torque. Derivation of the CBE correction factor equation is presented. Validation upon this new equation is performed by comparing the result with electrical measurement on the pumping unit motor. Using the calculated CBT from the new equation, SCADA Optimization Software performs gearbox torque and pumping unit balance analysis based on every collected dynamometer card. Calculated CBT from the new equation provided results in gearbox torque distribution pattern that match with measured electrical parameter distribution along the stroke. This CBT value assists SCADA optimization software to calculate pumping unit balance and gearbox torque. Alarm in the SCADA optimization software that coming from an anomaly on pumping unit balance and gearbox torque help operator to do preventive maintenance so that pumping unit component especially the gearbox could have longer run life.

In order to calculate the working mode of a sucker-rod pump driven by the beam pumping unit and a jet pump during their simultaneous operation, pressure and temperature distribution along the wellbore from the bottom to the wellhead is determined for the real oil well 753-D "Dolynanaftogaz" Field Office. To calculate these parameters an improved methodology based on known Poettmann-Carpenter and Baxendel methods is used. As a result, the imperfection of these methods was eliminated, namely the assumption that pressure and temperature behavior along the wellbore is linear. This led to obtaining results which are up to 23% more accurate. In addition, using the algorithm for determining the density of perfect (ideal) liquid-gas mixture, the author has calculated the velocities of gas-water-oil and water-oil mixtures for a number of sections along the production tubing at different angles of the crank position in the beam pumping unit. The indicated values make it possible to determine the depth of the oilgas jet pump location in the well, and, consequently, the parameters at its input (pressure, temperature, velocity of the liquid-gas mixture, its density, etc.). Besides, the author studies the dependence which describes the behavior of the liquid-gas mixture density along the wellbore, as well as the relations between the density of the free oil gas, thevolumetric consumption gas content of the flow and the placement of the section under consideration. All of the above-mentioned algorithms were implemented using developed computer programs. The obtained results give a possibility to choose the location of the jet pump in the well which is the most advantageous one for ensuring maximum pressure reduction and the decrease in the stem load.

Automatic Balancing

The efficiency of sucker rod pump installations, which have become widespread in mechanized lift practice, is largely determined by the balance of the drive. During the operation of sucker rod installations, the balance of loads acting on the rod string and the drive can change significantly due to changes in the dynamic fluid level, which leads to a decrease in balance and an increase in loads on the pumping equipment units. The increase and decrease in the dynamic level in accordance with the pumping and accumulation cycle occurs in wells operating in the periodic pumping mode. It is shown that during the operation of equipment in a periodic mode, fluctuations in the dynamic level and, accordingly, in the loads acting on the nodes occur. This leads to the need for dynamic adjustment of the balancing weights to ensure the balance of the pumping unit. A system for automatic balancing of the rod drive has been developed, including a balancing counterweight, an electric motor that moves the load along the balance beam, a propeller and a computing unit. To study the effectiveness of the proposed device, a complex mathematical model of the joint operation of the reservoir - well - sucker rod pump - rod string – pumping unit has been developed. It is shown that due to the dynamic adjustment of the balance counterweight position, the automatic balancing system makes it possible to significantly reduce the amplitude value of the torque on the crank shaft (in comparison with the traditional rod installation) and provide a more uniform load of the electric motor. Equalization of torque and motor load reduces the power consumption of the unit.
