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.

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.

It is well known that production parameters of the wells operated via sucker-rod pumps are defined by theoretical delivery of applied facilities. Consequently, the issue of efficient usage of production capacity of sucker-rod pumps is of great importance. Particularly, the solution of the issues associated with the energy-saving consumption of power, supplies and other material valuables in the large production well stock is sufficiently important for long-term developed fields. In this view, the research surveys on the potentiality of the theoretical delivery of sucker-rod pumps in Balakhany-Sabunchu-Ramana field have been carried out based on the actual field data. A system analysis has been conducted for all wells on the recovery rate of the liquid, oil, water and theoretical delivery on the basis of which functional dependencies of rates, flooding and specific theoretical delivery of sucker-rod pumps have been developed and their mathematical models found as well. The aspects of more efficient usage of production capacity of sucker-rod pumps have been defined. The results of carried out studies may be successfully implemented in the solution of tasks on the efficiency increase of sucker-rod pumps operation, specifically in long-term developed fields.

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.

Objective/Scope: Challenges of sucker rod pumping operation in high gas and solid production;The implementation of integrated down-hole gas and solid separation in one device. Method procedure/processes: Old Rimau Fields in South Sumatera produce oil from sandstone reservoir with GOR above 800 scf/stb and solid production resulted from fracturing proppant flow back. Due to these conditions, some problems such as gas lock or interference, pump leakage, and rod parted were discovered which resulting in low SRP run life. The installation of sand screen and gas anchor has been implemented to encounter this issue. However, this initiative still ineffective due to limited conditions. If the sand screen was installed to control the sand, then the gas anchor to control the gas could not be installed and vice versa.Results, observations, conclusions: Integrated solid and gas handling called "hybrid" device has been introduced. The device is connected directly at the bottom of down-hole pump consist of three section, the upper section for intake and gas separator, the middle section for gas and solid separator, and lower one for solid container. The first utilization was conducted in three SRP wells, which are KG-09, LKP-21, and KG-10. Previously, these wells were shut-in due to down-hole problem. After installing the device while well service, the SRP run normally to produce the oil. The increasing of pump load performance was also obtained, indicated by the dyna card. At this time, the SRP is still running and run life is still under surveillance. This paper will explain the new technology end-to-end implementation of the integrated down-hole sand and gas control in one device for Sucker Rod Pump (SRP) system.
