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.

The measurement of the dynamic liquid level is of great importance during the oil-producing process of rod pumping wells. It may affect the production of oil fields and motor efficiency. However, the dynamic liquid level is difficult to detect because of the circumstances in the downhole of rod pump wells. In this paper. Firstly, according to the working principles of the sucker rod pump, the mechanical models of the pumping motor and four-bar linkage mechanism are respectively built. Secondly, for the underground frictions, a mechanical model based on the energy conservation equation is built and then the mechanism model is built between the dynamic liquid level and power of the motor. To improve the accuracy of the mechanism model, a novel method based on an artificial fish swarm algorithm optimization Gaborc-kernel extreme learning machine is used to establish a soft sensor dynamic liquid level error compensation model. The mechanism model is paralleled with the soft sensor model to establish a hybrid model of dynamic liquid level. Eventually, the AFSA-Gaborc-KELM soft sensor hybrid model is verified by using the oil dataset collected from the electrical parameter acquisition equipment. This hybrid model is compared with some other models. In the comparison, the proposed hybrid model has better performance and prediction accuracy for the dynamic liquid level than the BP hybrid model, GA-ELM hybrid model, and LSSVM hybrid model.

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.

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.

One of the solutions to reduce the production and maintenance costs of the sucker rod pumping installations is to develop automated systems for regulating and controlling their operations. The development of these automated systems requires an attentive modeling of the dynamics of the mechanism of the pumping unit, process in which the identification of the values of the parameters involved in the calculations plays an essential role. The paper presents the manner of determining the values of some parameters of the mechanism of a C-320D-256-100 pumping unit starting from the variation on a cinematic cycle of the motor torque at the crank shaft. Simulations were performed with a computer program developed by the authors, and the experimental records were processed with the program Total Well Management.

Sucker Rod Pump

AbstractIn many oil reservoirs worldwide, the downhole pressure does not have the ability to lift the produced fluids to the surface. In order to produce these fluids, pumps are used to artificially lift the fluids; this method is referred to as artificial lift. More than seventy percent of all currently producing oil wells are being produced by artificial lift methods. One of the most applied artificial lift methods is sucker rod pump. Sucker rod pumps are considered a well-established technology in the oil and gas industry and thus are easy to apply, very common worldwide, and low in capital and operational costs. Many advancements in technology have been applied to improve sucker rod pumps performance, applicability range, and diagnostics. With these advancements, it is important to be able to constantly provide an updated review and guide to the utilization of the sucker rod pumps. This research provides an updated comprehensive review of sucker rod pumps components, diagnostics methods, mathematical models, and common failures experienced in the field and how to prevent and mitigate these failures. Based on the review conducted, a new classification of all the methods that can fall under the sucker rod pump technology based on newly introduced sucker rod pump methods in the industry has been introduced. Several field cases studies from wells worldwide are also discussed in this research to highlight some of the main features of sucker rod pumps. Finally, the advantages and limitations of sucker rod pumps are mentioned based on the updated review. The findings of this study can help increase the understanding of the different sucker rod pumps and provide a holistic view of the beam rod pump and its properties and modeling.
