AI Technical Summary

Technical Problem

Existing coiled tubing equipment cannot be lowered to the target location in horizontal well construction due to the large difference in curvature radius and friction, thus failing to meet the construction requirements of ultra-long horizontal wells.

Method used

Design a continuous and controllable coiled tubing straightening device. The device uses an adjusting block and a hydraulic system to control the pressure rollers to straighten the coiled tubing, increasing its radius of curvature to meet construction requirements.

Benefits of technology

It increases the running depth of coiled tubing in horizontal wells, reduces the number of deformations, extends service life, and lowers equipment and production costs.
