Overview
Development of a novel design of rod pumping unit drives for the oil and gas industry. Co-authored 2 patents and published 1 journal article.
Problems in Existing Designs
- Horse-head (arc-head) is massive and structurally complex in manufacture, has increased requirements for manufacturing accuracy
- Difficulties associated with the use of a flexible link wound on the head of the balancer
- Sensitivity to vibrations of pumping unit
- Large height of the balancer attachment point requires a massive foundation of high-quality concrete, resulting in high metal consumption
- Poor balancing, resulting in shock loads on the crank finger
- Unfavorable force transmission at small angles when stroke is increased
Contributions
Studied dynamics of the new sucker-rod design. Conducted kinematic synthesis and developed computational and simulation models. The novel design eliminates the drawbacks listed above.
