2003年,在Campos盆地2888m水深处完成的小井眼钻井创造了巴西深水钻井记录。该井使用陆上防喷器安全完钻。本文将分两个方面进行详细讨论:首先讨论该井和某一假设的常规井之间在井控作业方面的技术问题;其次讨论陆上防喷器技术问题。主要目的是深入探讨使用陆上防喷器勘探开发巴西深水和超深水储层方面的问题,重点讨论井控问题。
Slimhole drilling completed at a depth of 2888 m in the Campos Basin in 2003 created a record for deepwater drilling in Brazil. The well was drilled safely using a land blowout preventer. This article will be discussed in detail in two areas: first, the technical aspects of well control operations between the well and a hypothetical conventional well; and second, the technical issues of land-based blowout preventers. The main objective is to explore in depth the exploration and development of deepwater and ultra-deepwater reservoirs in Brazil using land-based blowout preventers, with a focus on well control.
