Product Introduction

Low-carbon Microalloyed Coiled Tubing Description

Low-carbon microalloyed coiled tubing has high strength and good plastic,which is developed by high strength low alloy steel (HSLA) and high frequency welding (HFW) technology. Single tubing is continuously milled on production line and wrapped onto a spool to a certain length for delivery,the length per reel can reach 8000 meters.

Microalloyed Coiled Tubing Applications of Coiled Tubing:‌

‌Drilling & Workover‌

In complex well types such as ultra-deep wells and horizontal wells, coiled tubing efficiently performs drilling, wellbore cleaning, and tool fishing operations. For instance, Bohai Drilling adopted a "1+3" operation mode in shale oil platform wells, significantly enhancing operational efficiency.

‌Completion & Production‌

Utilizing continuous circulation and pressure-containing characteristics, it enables completion string running, production well testing, and oil/gas production operations.

‌Reservoir Stimulation‌

Precisely executes staged fracturing, acidizing and other techniques to improve reservoir permeability and production. At Guan-Ye No.8 Platform, this technology helped reduce commissioning cycle by 6.5 days.

‌Refining & Oil/Gas Gathering/Transportation‌

Gradually expanding into refining applications including pipeline cleaning and medium transportation maintenance.
