定向井稳定器的合理选择初探

A PRELIMINARY PROBE INTO THE RATIONAL SELECTION OF DIRECTIONAL WELL STABILIZERS

根据稳定器在定向钻井过程中的工作特点,针对软、硬地层的具体情况,在基于实现预想造斜效果、安全划眼、顺利起下钻的原则下,分析了稳定器在不同情况下的受力状况。找到了软、硬地层中合理选择稳定器的办法,有利于达到设计的目的和安全钻进。

According to the working characteristics of stabilizer during drilling and concrete conditions of soft and hard formations,the forced situations of the stabilizers in various conditions are analysed to achieve the anticipated deflecting results,safely reaming and successfully making a round trip. The method of rationally selecting stabilizers in soft and hard formations is presented.
