  • Multi-channel, combination coiled tubing strings for hydraulically driven downhole pump
    Patent number: 8276658
    Abstract: This invention relates to a downhole hydraulic pump for hydrocarbon wells that is installed and operated using coiled tubing. The downhole hydraulic pump is driven by a hydraulic power system positioned at the surface and connected through a closed loop system using multiple channels of the coiled tubing. The coiled tubing is formed of a combination of channels including strength component such as steel and having one channel that is at least lined with a non-metallic corrosion resistant surface where clean hydraulic fluid is carried from the hydraulic power system to the downhole hydraulic pump through the non-metallic corrosion resistant channel so to be less likely to pick up manufacturing and environmental particulates and corrosion by-products within the channel carrying the hydraulic fluid to the downhole hydraulic pump. The non-metallic corrosion resistant lined channel may comprise plastic pipe.
