- Abstract
Sucker-rod deep-well pumping units widely used in oil production are described. It is shown that oil production depends on the operating conditions of these units, which are selected based on the results of analyzing closed dynamometer charts. The latter describe the load on the suspension depending on the stroke of the polished rod of the unit. The quality of preparing the charts determines the ability to diagnose the technical condition of the unit. The trends in the development of existing dynamometer systems and methods for diagnosing the condition of a sucker-rod deep-well pumping unit have been analyzed. One of the ways to create an intelligent intertraverse dynamograph is considered based on a messdose of a pocket dynamograph with the use of modern pressure, acceleration, and temperature sensors; STM32 controllers; a graphic liquid crystal display with an I2C interface; radio communication protocols and digital technologies for processing periodic sensor signals. The existing dynamometer systems along with force and stroke sensors installed in various unit locations were analyzed, and the possibility of developing an intelligent stationary dynamograph by utilizing the latest advances in the field of technology and equipment for analyzing noises of the measured signals has been demonstrated. The proposed dynamograph should ensure early diagnostics of the technical condition of the unit, while satisfying the following criteria: low cost; ease of assembly; high sensitivity, reliability, flexibility, and accuracy. A block diagram of an intelligent intertraverse dynamograph for a sucker-rod deep-well pumping unit is presented, which is based on a pocket dynamograph messdose. The proposed intelligent intertraverse dynamograph will be useful for early diagnostics of the technical condition of deep-well pumps and tubing strings connecting them with the ground equipment, which will ultimately contribute to improving reliability of oil production equipment. The proposed intelligent intertraverse dynamograph can also be used in other engineering fields, where there is a need to measure force.
