Dual 92 Plunger
The Eagle Dual 92 Plunger system represents a true advancement in downhole pump technology. Sand, grit, iron sulfide, and other fines which normally contaminate the produced oil and water can now quickly pass through the pump assembly. The Dual 92 Plunger has a 92R to 98R hardness and is equipped with grooves to allow small solids accumulation, thus reducing wear. No longer are residual concentrations of these particulates allowed to collect between the barrel and plunger.
Clearance between conventional pump plungers and barrels permit some fluid bypass, or slippage between these surfaces. Within this void space, sand, formation fines and other particulates can accumulate. During the normal up-and-down motions of the plunger, these accumulations cause rapid wear, usually in the form of vertical scoring, to both the plunger and barrel surfaces. Moreover, frictional forces generated by these accumulations cause excessive stresses to be generated throughout the pump and rod-string which often result in a stuck pump, automatic shut down of the pumping unit, or a parted rod string.
Repairs necessitated by the above forms of damage, plus revenues lost during resulting downtime, cost the oil and gas industry tens of millions of dollars each year. By incorporating the Dual 92 Plunger system within the pump assembly, stuck plungers and premature wear of barrel and plunger surfaces can be eliminated. Costly well servicing and pump replacements can be reduced to a minimum.
How is this possible? During the downstroke the Dual 92 Plunger, along with the Cyclone Seat Plug forces any entrained particulates collected within the space between barrel and plunger inward through the axial evacuation ports and into the center of the plunger. Here, they commingle with other fluids entering the pump and are displaced into the tubing. Throughout the upstroke particulates are also collected within the tapered neck of the Dual 92 Plunger, where, during the downstroke, they are flushed upward and enter the tubing through the Eagle Cyclone Top Adapter.
There are additional benefits of the Dual 92 Plunger when run with the axial ported technology of the Eagle Cyclone System. When run together, these two tools cause the fluid and particulates to constantly rotate. This permits the pump barrel and plunger to wear more evenly, resulting in longer pump life and a more cost-efficient pump assembly. While the pump is not operational, settling solids are redirected into the internal area of the plunger, reducing the possibility of stuck plungers and excessive barrel wear.
For best results, the complete Eagle Cyclone Pump System is recommended.
