| Abstract: | In order to play the application of ultra high strength CT110 coiled tubing in deep well, extra-deep well and extended reach horizontal well production and stable production, as well as the advantages in the shale gas staged fracturing, drilling and milling bridge plug. In this article, it analyzed the microstructure and properties of domestic CT110 grade coiled tubing. The results indicated that the overall performance of CT110 coiled tubing is good, the performance indexes such as strength, hardness can meet the requirements of API SPEC 5ST standard, and the strength and plasticity match well, the comprehensive performance reaches rater high level. And the main performance indexes of domestic CT110 coiled tubing reach or exceed those of the same specification imported CT110 coiled tubing. |
