Longer, deviated wells push drill pipe limits

摘要

Drill pipe technical performance is rarely the starting point for well planning - engineers expect that drill pipe will handle the challenges, loads and environments that it encounters. Until recently, drill pipe has been able to keep ahead of drilling challenges. "Dumb iron," as it is described in the industry, has evolved into a highly engineered drilling product, designed with features to reduce drilling fatigue, improve torsional and tensile strength, resolve slip crushing issues, and allow it to operate in sour drilling conditions.
