Use of a chopper mechanism to add fibers to a well

摘要

A chopper mechanism for providing a fiber to a fluid at an oilfield. The chopper mechanism may be employed to process the fiber from an uncut form to a cut form in order to provide a mixture of the fluid and the fiber with flowback inhibiting character. Techniques of employing the chopper mechanism may be utilized at the site of an oilfield for applications such as fracturing, cementing, and drilling. Additionally, the chopper mechanism itself may be made available as a large high capacity chopper assembly, or a smaller handheld chopper gun for slower rate fiber supply operations.

1. A method of treating a well at an oilfield with a fluid mixture, the method comprising:
providing a fluid to the oilfield; providing an uncut form of a fiber in the form of an interconnected and continuous plurality of cheeses; interconnecting the plurality of cheeses to form a continuous pallet of interconnected cheeses; andadding the fiber to the fluid to form the mixture, said adding comprising:
feeding the uncut form of the fiber to a chopper gun, wherein said feeding is configured to be performed continuously for the duration of the treating; operating the chopper gun to convert the uncut form of the fiber to a cut form of the fiber to form a plurality of cut fibers; delivering and metering the plurality of cut fibers from the chopper gun to the fluid to provide the mixture with a flowback inhibiting character; andinjecting the fluid mixture into the well.
