连续油管新技术 解决长距离作业难题

The length of coiled-tubing strings manufactured has been increasing in order to keep pace with the longer laterals being drilled in today’s wells. However, adding to the length of a coiled-tubing string greatly increases the load the unit must carry. In some cases, these heavier loads can run afoul of permitting requirements. National Oilwell Varco (NOV) developed the Genesis platform to provide durable long-tubing strings on a unit that meets permit requirements. In this video from the 2018 SPE/ICoTA Coiled Tubing and Well Intervention Conference in The Woodlands, Texas, Norm Fossheim, Director of Engineering at NOV, explains the features of the new unit, including its ability to provide both hydraulic and electric power. He also discusses the future of the Genesis line and associated coiled-tubing units.

Genesis™ Coiled Tubing Unit

Our newest coiled tubing product line, Genesis, ensures you can quickly and safely get to your operations. Genesis was created to support our vision of building quality, fit-for-purpose products in a timely fashion, balanced with the need for safety. Featuring high-visibility cabins, HMI displays, electric over hydraulic controls, and industry leading injector technology – the future of coiled tubing is here.

This four-axle coiled tubing unit is optimized to maximize your tubing payload and legally carries up to 24,000 ft of 2⅜” coiled tubing with a dry tubing tare of 110,000 lb, based on Colorado policy and permits. It is also permittable in Texas, New Mexico, Oklahoma, Louisiana, Ohio, and Wyoming

You’ve asked for a line of single-trailer coiled tubing units that are structurally capable of carrying the largest tubing load possible into the most diverse group of basins without exceeding axle and tire ratings.

ST2558 Coiled Tubing Unit

With the rollout of our Genesis™ ST2558, we have once again pushed the envelope in the world of high-capacity single-trailer coiled tubing units. Touting a maximum capacity of 25,000 ft of 2⅝-in. tubing and capable of shouldering a maximum tubing load of 140,000 lb, this model was designed to carry the largest strings into the challenging environments of West Texas and New Mexico.

Leveraging our experience and global engineering and manufacturing resources, the ST2558 represents a significant breakthrough in the evolution of coiled tubing transportation.

Nitrogen pumping product

Our newest nitrogen pumping product line, Genesis, ensures you can operate with the highest level of efficiency. The Genesis™ automatic nitrogen unit with CTES™ controls provides advanced control of the nitrogen’s rate, temperature, and pressure while monitoring safety limits during pumping operations. The unit receives requests from the operator remotely for mode changes. The CTES controls evaluate and adjust operations to reduce the startup time of your unit while increasing efficiencies.

Mundane actions, like heat builder control and pump speed, are managed within operator preset ranges. The unit reduces unsafe actions and conditions by monitoring the condition of liquid nitrogen in the pumps and alerting the operator if targets stray away from optimal conditions while providing a tight range of operation to maintain job stability.

The CTES condition based maintenance (CBM) system is a custom real-time monitoring system for the unit when customer-provided Internet or 4G LTE connection is available. The system improves uptime and reduces maintenance costs associated with personnel and inventory requirements through early identification of potential component failures. The installed CBM system monitors process and machine data locally while transferring the data to GoConnect™ for intervention and stimulation equipment to allow remote viewing of the unit’s data.
