川西深井钻井提速阶段性技术成果

On the Phase Technique Fruit of Deep Well Drilling Acceleration at West Part of Sichuan

四川盆地是中石化集团公司天然气大发展的主要地区,川西地区深层须家河组蕴藏着巨大的天然气资源,是西南油气田今后一个时期天然气储量、产量增长的重要领域和主战场。去年,集团公司组织了川西地区深井钻井提速科技攻关活动,近一年来,川西地区加强技术攻关,取得了川西深井提速的阶段性成功,同时取得了井身结构优化、钻井液体系、钻头选型和欠平衡技术应用等方面的阶段性技术成果.

Sichuan Basin is the main area of great development of natural gas for Sinopec Group Company.Deep in Xujiahe Group in western Sichuan contains vast reservoir of natural gas resources,it is the important area and the main battlefield for the natural gas output growth of southwest oil and gas field in the next period.Last year,group company organized speeding up drilling science and technology key task for western Sichuan.Over the past year,speeding deep well has acquired the initial success in western Sichuan,and has made well structure optimization,drilling fluid system,bit selection and application of underbalanced technology and other aspects technological achievements of stage.
