定向井/复合井

优化的工程和钻井实践有助于打破大位移井的记录

本文介绍了采用 12δ-in 大口径设计钻探大位移井的预先计划、执行和结果。作为主要的步出部分并部署 9 英寸。实际垂直深度为 4,200 英尺的浅套管。

完整的论文描述了大位移钻孔 (ERD) 的预先计划、执行和结果，该钻孔采用 12 英寸大孔径设计作为主要步距部分并部署 9 英寸。在 4,200 英尺的浅真实垂直深度 (TVD) 上进行套管。计划并执行从一口井到下一口井的 ERD 比率和复杂性的逐步增加，直到实现破纪录的井，部署 8 公里的 9 英寸。

Optimized Engineering and Drilling Practices Help Break Record for Extended-Reach Well

This paper describes preplanning, execution, and results of drilling extended-reach wells with a large-bore design of 12¼-in. as the main stepout section and deploying 9⅝-in. casing at a shallow true vertical depth of 4,200 ft.

The complete paper describes preplanning, execution, and results of extended-reach drilling (ERD) with a large-bore design of 12¼ in. as the main stepout section and deploying 9⅝-in. casing on a shallow true vertical depth (TVD) of 4,200 ft. Progressive increase of ERD ratio and complexity from one well to the next was planned and executed until a record-breaking well had been achieved, deploying 8 km of 9⅝-in.
