Indirect measurement of dynamometer card of pumping unit

2008 7th World Congress on Intelligent Control and Automation, 2008
The indirect measuring model was built, and the computation process of the model was introduced. Synchronization signals were used to obtain the corresponding relationship between the power of the drive motor and the displacement of the pumping unitpsilas rod. The indirect measuring model was incorporate into the oil field supervisory system using GPRS.

Determination of Downhole Dynamometer Cards for Deviated Wells

SPE Artificial Lift Conference — Latin America and Caribbean, 2015
Abstract This paper proposes a numerical solution for the calculation of the downhole dynamometer card for deviated wells equipped with sucker-rod pumping. The solution shown is based in the model developed for the project of sucker-rod pumping systems considering three-dimensional trajectories.

Binary Histogram of Oriented Gradients Based Dynamometer Card Recognition

2017 13th International Conference on Computational Intelligence and Security (CIS), 2017
Surface dynamometer card of pumping unit is a closed curve of load and displacement values in a pumping cycle, which reflects the operating condition of the sucker-rod pumping unit. Automatic analyzing and diagnosing the dynamometer card plays an important role in the process of oil and gas production.

A novel method of output metering with dynamometer card for SRPS under fault conditions

Journal of Petroleum Science and Engineering, 2020
Abstract Remote monitoring of sucker rod pumping system (SRPS) based on polished rod dynamometer cards (DC) is an effective means to reduce the operating costs and realize the real-time control. Nevertheless, how to obtain the working process and the production rate of SRPS from polished rod DC is always a puzzle because of complex down-hole motions.

Innovative Convolutional Neural Networks Applied in Dynamometer Cards Generation

SPE Western Regional Meeting, 2019
Abstract There are nearly 200,000 oil wells producing in PetroChina and 94% are sucker-rod pumping wells. Dynamometer card is essential for well diagnosis and optimization, which cost huge investment on sensor installations and maintenance. This paper present an innovative artificial intelligence method to get the card data directly from

Trend prediction of pumping well conditions using temporal dynamometer cards

2020 2nd International Conference on Machine Learning, Big Data and Business Intelligence (MLBDBI), 2020
Most of the oil wells in China use sucker rod pump. Traditionally, manual patrol is used to find the working conditions of pumping wells. In the trend of oilfield automation and intelligence, this traditional working mode can not adapt to the increasingly complex working conditions of the oilfield. Therefore, artificial intelligence technology has been

Use of Pattern-Recognition Techniques in Analyzing Downhole Dynamometer Cards

SPE Production Engineering, 1990
Summary Four pattern-matching methods are presented to evaluate the downhole condition of sucker-rod-pumped wells. Comparing the generated pump dynagraph of a well being tested to various downhole dynagraphs characteristic of particular rod-pump problems allows the pattern-matching methods to diagnose a variety of different pump ...

Motor Power Based Inversion of Dynamometer Cards Using Hybrid Model

2020 Chinese Control And Decision Conference (CCDC), 2020
The dynamometer card sensors' poor real-time performance and high maintenance costs limit the control and diagnosis for sucker rod pumps(SRP) in oil exploitation. The motor which is the power source of the whole pumping process can reflect the working state of the entire equipment. The motor power can be accessed easily and continuously.

The Study of Using Measured Power Cure to Derive Dynamometer Card Based on Calibration Method

Springer Series in Geomechanics and Geoengineering, 2021
There is currently a low precision in predicting the indirect dynamometer card with measured power cure. The indirect measured model of normal beam pumping unit based on the measured power cure was established, and taken into consideration comprehensively the effects of transmission efficiency of each node and moving part inertia on the dynamic ...
