Increasing reliability of wireline hangers of sucker-rod pumping units

It is well known that the bearings of the mechanism of the conventional pumping units are heavily loaded so that their design has to be accomplished very carefully. In this scope the values of the connection forces acting on these bearings has to be determined as accurately as possible. In the paper is presented the kinetostatic analysis of the mechanism of the conventional sucker rod pumping units, obtaining in this way the values of the connection forces in the joints and of the motor moment at the cranks shaft. For processing the experimental records it has been used the program Total Well Management. The simulations have been performed with a computer program developed by the authors using Maple programming environment.

The study of the dynamic model of the conventional sucker rod pumping units requires first determining the variation on the cinematic cycle of the synthesis parameters (the reduced moment and the reduced mass moment of inertia) and then the variation of the angular speed of the cranks, in response to the dynamic and resistant actions on the component elements that appear during operation. The paper presents the way of determining the variation on the cinematic cycle of the synthesis parameters of the dynamic model corresponding to the conventional pumping unit mechanism and of the variation of the angular speed of its cranks. The experimental records have been processed with the Total Well Management program. The simulations have been performed with a computer program developed by the author using the Maple programming environment.

Abstract The problem of measuring the flow rate of wells with low production rates is relevant for many oil fields. Conventional flow meters are not suitable for such cases, and installing an additional flow meter for each well is impractical. At the same time, wells with sucker-rod pumping units (the majority of wells) are outfitted with dynamographs for continuous diagnostics of the pumping equipment state. Dynamograms allow determining the theoretical flow rate of the well easily, however, a mathematical model is required to estimate the actual flow rate. For the correction of flow rate obtained from dynamograms, the authors of this study propose using models based on regression equations that link the calculated valueswith the measurements made by a reference instrument. The results of the experiments have confirmed the eligibility of this approach.
