Sucker rod pump lifting technology development is currently the most widely used, the most mature, the most complete supporting facilities. In the sucker rod pump lifting system of heavy oil, the larger of sucker rod and the friction liquid is one of the important factors that affect the lifting system. The friction between sucker rod and the liquid is needed to be accurately calculated in the scientific design of rod string matching. In this paper, friction between sucker rod and the liquid is the research object. The practical problems for the properties of the heavy oil which is changed with the temperature abnormally higher than the conventional crude oil. Temperature and pressure in the wellbore which effect on the viscosity of heavy oil is further researched. The calculation model of the wellbore temperature field and pressure field distribution is established. Furthermore, we put forward a set of suitable calculation model of the friction between sucker rod and the liquid in the sucker rod pump lifting system for heavy oil. At the same time, Using visual c # language programme computing software is compiled and generates the heavy oil viscosity curve which changed with various factors. On the basis of the work performed, the data of more than 500 Wells is calculated successfully. The results show that model prediction accuracy is higher than the normal model (Relative errors are less than 8%).

Field SS is a Heavy Oil field which means high viscosity oil making it difficult to flow. Therefore, artificial lift was used in this field to help lifting the high viscosity fluid, i.e. sucker rod pump (SRP). In the last several years, problem of the damage to the rod string was frequently occur. Rod string damage is usually indicated by the occurrence of broken or detached components. In order to overcome the damage of rod string components on the sucker rod pump, several parameters that causes rod string damage in 41 well samples in the field SS were analyzed and then recommendations were made as an alternative to minimize the occurrence of rod string damage. After analyzing the parameters that can cause rod string damage on 41 well samples in SS field, the cause of the breakdown of rod string is fluid pounding for 37 samples well, while the causes for 4 samples of other wells is not detected. After that, recommendation efforts is done, like size down pump speed and stroke length for 9 samples of wells, size down pump size and pump speed for 6 samples of wells and size down pump speed for 22 samples well. As for the undetected cause 4 samples of wells, is recommended to do proactive well service.

The article is devoted to the diagnostics of the well pumping equipment operation using wells production viscosity measurement results obtained by the developed field device VNP 1-4, 0-90. The method for making measurements with a field oil viscometer was developed in accordance with the provisions of GOST R 8.563, GOST R ISO 5725-2. It has gained certification and entered the State Register of the Russian Federation. On the basis of preliminary laboratory studies of oils viscosity from the group of fields of LLC UK «Sheshmaoil», a formula was obtained for the dependence of oil emulsions viscosity on temperature and the content of formation water in them. Viscosity measurements obtained with the developed device in field conditions have shown the applicability of the method for calculating the watered oil viscosity.The application of the results of measuring the watered oil viscosity at the wellhead allows diagnosing the downhole sucker rod pump unit operation based on the construction of a dynamic model of its operation.

Based on the informatization and intelligent construction of an oilfield, this paper proposes a new method for calculating inflow performance relationship in sucker rod pump wells, which solves the limitations of current IPR curve calculation method in practical application. By analyzing the forming principle of the dynamometer card, the plate of abnormal dynamometer card is created innovatively, and the recognition model of abnormal dynamometer card based on “feature recognition” is established to ensure the accuracy of the dynamometer card. By analyzing the curvature of each point on the curve of downhole pump dynamometer card, the opening and closing points of standing valve and traveling valve are determined, and the models for calculating fluid production and bottom hole flowing pressure are established to obtain the data of fluid production and bottom hole flowing pressure of sucker rod pump wells. Finally, a calculation model of inflow performance relationship fitted with the calculated fluid production and bottom hole flowing pressure data based on genetic algorithm is established to realize calculation of oil well inflow performance relationship curve. The field application and analysis results show that the inflow performance relationship curve calculated by the model in this paper fits well with the measured data points, indicating that the calculation model has high accuracy and can provide theoretical and technical support for the field. Moreover, the real-time acquisition of dynamometer cards can provide real-time data source for this method, improve the timeliness of oil well production analysis, and help to reduce the production management costs and improve the production efficiency and benefit.

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.
