Study on Optimal Drilling Design in Block 1 of Central Junggar Basin

摘要:

围绕钻井工程设计优化展开研究，论述了准噶尔盆地中部1区井身结构优化过程，提出了井身结构优化方案；建立了该区岩石可钻性剖面，结合钻头使用效果评价，推荐了钻头选型方案；介绍了该区钻井液体系优选及使用情况。形成了准噶尔盆地中部1区钻井设计优化方案，提出了后续研究方向。

Abstract:

Drilling design and optimization were researched. The development of casing program in block 1 of central Junggar Basin was discussed with the casing program optimization scheme put forward; a bit selection scheme was recommended base on the rock drillability profile and the evaluation of bit performance; and drilling fluid system optimization and application was also introduced. Drilling design for block 1 of central Junggar Basin was formed and the future research direction was presented.
