Qué es la tubería de revestimiento OCTG?
La tubería de revestimiento OCTG significa "Oil Country Tubular Goods" (productos tubulares para campos petrolíferos) y se refiere a una gama de productos laminados sin costura, como tuberías de perforación, revestimiento y tubos utilizados en la perforación y producción de petróleo y gas. La tubería de revestimiento se utiliza para revestir las paredes de un pozo para evitar el derrumbe y separar las diferentes capas de suelo o roca. Estas tuberías están hechas de varios grados de acero y están diseñadas para soportar las altas presiones y los entornos corrosivos que se encuentran en las operaciones de pozos de petróleo y gas.
Cuáles son los tamaños de las tuberías de revestimiento OCTG?
El tamaño de las tuberías de revestimiento OCTG se especifica por su diámetro exterior y el espesor de la pared. Estos tamaños suelen estar estandarizados según los estándares del Instituto Americano del Petróleo (API). Los tamaños comunes de tuberías de revestimiento OCTG varían de 4 1/2 pulgadas a 20 pulgadas de diámetro exterior, con distintos espesores de pared para adaptarse a diferentes profundidades de pozo y requisitos de presión.
Por ejemplo, un tamaño común de tubería de revestimiento OCTG podría especificarse como "7" (7,00 pulgadas de diámetro exterior) con su espesor de pared específico especificado en libras por pie o milímetros. El tamaño exacto y las especificaciones de la tubería de revestimiento dependen de las condiciones de perforación específicas, el diseño del pozo y los requisitos reglamentarios para las operaciones de petróleo y gas.
Este texto mostrará la tabla de tamaños de tubería de revestimiento normal; puede obtener información detallada en la tabla de tamaños de tubería de revestimiento a continuación.
