据俄罗斯油气网10月25日诺维港报道，俄罗斯天然气工业石油公司(俄气石油)日前在其旗下的Novoportovskoye油田创造了一个钻井速度的新纪录，在不到3天(2.93天或70小时33分钟)的时间里完成了1000米的水平竖井。

这个新纪录是通过使用一个实验性的钻头实现的，钻头的设计已经被国内生产商在冻土层实施诺维港项目的钻井作业时做了专门调整。这种新型钻头使钻井速度提高了一倍，达到每小时130米。总钻透深度达到5921米。

使用新技术和创新设备是俄气石油“技术极限”项目的一个组成部分。“技术极限”项目是一个全面的综合项目，旨在改善钻井工艺，使在具有挑战性的地质条件下建造高度复杂的油井成为可能。

在这个方案的帮助下，俄气石油-亚马尔的一个专家小组通过高质量的工艺规划、及时的设备准备、细致的风险评估和经验教训分析，降低了钻井成本和交货时间，并提高了钻井效率。

Helped by new technologies, Gazprom Neft sets a new record in drilling speeds

Neftegaz.RU. A new record in well-drilling at Gazprom Neft has been set at the company’s Novoportovskoye field, with a 1,000 m horizontal shaft being covered in just under 3 days (2.93 days or 70 hours and 33 minutes).

This result was achieved by using an experimental drill bit, the design of which had been specially fine-tuned by domestic producers for drilling in permafrost for use at the Novy Port project. This new drill-bit has made it possible to double drilling speeds, to 130 m per hour. The total penetration was 5,921 m.

Using new technologies and innovative equipment forms part of Gazprom Neft’s ?Technical Limits? project — a comprehensive and integrated project to improve drilling processes, making it possible to build highly complex wells under challenging geological conditions.

Helped by this programme, a specialist team at Gazpromneft-Yamal were able to cut drilling costs and lead-times, as well as increasing drilling efficiency, through high-quality process planning, timely equipment preparation, meticulous risk assessments and analysis of lessons learned.
