BALL INJECTOR MODEL 202

FUNCTIONALITY

• DNV Type Approval for Model 201 Ball Injector

• The GKD Ball Injector, also known as a “Ball Gun” or a “Ball Sealer”, originated in the late 1970’s in response to requests from some of the leading well stimulation companies in Western Canada. The GKD Ball Injector and its predecessors have been success-fully deployed in oil fi elds around the world since the early 1980’s. The most recent version of the GKD Ball Injector has been in operation since 1995.

• The GKD Ball Injector is used to inject balls together with a pressurized acid solution into the well. The balls are carried down to the perforations by the acid at the rate that the acid is being pumped. The balls follow the fl ow towards the open perforations until they seal against the open perforations, at which point the acid and an increased pressure is applied against the perforations that are not open or not fully open. This reaction opens more perforations to the acid. This can be done throughout the acid job until all the perforations are open and all the perforation tunnels have been acidized, generally resulting in bet-ter fl owback and increased infl ow from the reservoir. When the acidization process is complete, the injected balls fl oat to the top of the well if positively buoyant balls are used or sink to the bottom if negatively buoy-ant balls are used.

OPERATION

• The balls can be injected by manually turning the Ball Injector’s vane shaft with the supplied hand crank thereby releasing balls into the pressurized stream of acidic solution. However, because this pres-surized stream can reach pressures of up to 15,000 PSI, most service companies use the GKD Ball Injec-tor with the remote controlled Motor Drive Package for safer operation.

Funcionalidad

• El inyector de bolas de GKD, conocido también como “pistola de bolas” o “sellador de bolas”, surgió a fines de los años 70 en respuesta a las solicitudes de algunas compañías líderes en estimulación de pozos en el oeste de Canadá. El inyector de bolas de GKD y sus predecesores han sido implementados exitosamente en campos petroleros de todo el mundo desde principios de los 80.

• El inyector de bolas de GKD se utiliza para inyectar bolas junto con una solución ácida presurizada (fracturación ácida o acidificación de matriz) en el interior del pozo. El ácido transporta las bolas hacia el interior de las perforaciones a la velocidad que se bombea el ácido. Las bolas fluyen hacia las perforaciones abiertas hasta que crean un sello contra ellas, momento en el cual se aplican el ácido y mayor presión contra las perforaciones que no están abiertas o que están parcialmente abiertas. Esta reacción crea perforaciones con el ácido y repara el daño del pozo: acidificación de matriz.

Con presiones mayores, la acidificación de fractura se utiliza para aumentar la efectividad del pozo: fracturamiento ácido. En ambos casos, el resultado consiste en control de fluido dirigido, minimización de la pérdida de fluido, disminución del factor de daño y mejora del contraflujo. Una vez que finaliza el proceso de fracturamiento ácido, las bolas inyectadas flotan hacia la superficie del pozo si tienen flotabilidad positiva, se hunden hacia el fondo si su flotabilidad es negativa o se disuelven si son biodegrables.

Operación

• Es posible inyectar las bolas manualmente girando el eje de paleta del inyector de bolas con la manivela suministrada, liberando así las bolas hacia el flujo presurizado de la solución acídica. Sin embargo, debido al riesgo que representa trabajar con grandes volúmenes de ácidos de alta potencia a presiones elevadas, la mayoría de las compañías de servicios utilizan el inyector de bolas de GKD con el paquete del variador de motor operado mediante.
