摘要:
为了发挥CT110超高强度连续管在深井、超深井及大位移水平井增产和稳产过程中的应用以及在页岩气分段压裂、钻磨桥塞等作业中的优势，对国产CT110钢级连续管的组织与性能进行了分析。结果表明，CT110连续管整体性能良好，强度、硬度等性能指标均满足API SPEC 5ST标准要求，且强度和塑性匹配良好，综合性能达到较好水平, 同时国产CT110连续管主要性能指标达到或优于同规格进口CT110连续管。
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.
