井眼曲率作为衡量工具造斜能力和评价井身质量的重要指标之一，对实现安全、快速、高效钻井具有重要意义。

Borehole curvature is one of significant index to evaluate Angle build-up capacity and wellbore quality, is very important to realize safety, speedily and efficiently drilling.

使之在钻井、完井、固井过程中不发生溢流(井喷)或井漏事故，从而实现安全，快速，低成本钻进。

In well drilling and completion, cementing the process does not overflow occurs (at) or well leakage accidents, and realize safe, rapid and low cost of drilling.

因此如何快速地控制失控井喷，甚至使喷井恢复到安全钻井状态，至今仍然是值得持续、深入研究的课题。

So how to quickly control the blowout and bring the accident well to a safety state is still worth to continuing and in-depth study.
