钻井实践证明,固齿质量好坏严重地影响着镶齿钻头的工作寿命。随着镶齿钻头适用的地层范围日益扩大,以及高刃楔形齿钻头的推广使用,镶齿钻头的工作条件更加繁重,它对固齿质量提出了更高的要求。为了深入分析影响固齿质量的有关因素,进一步探索提高固齿强度的工艺措施,我们和上海第一石油机械厂协作对影响固齿质量的主要因素进行了初步的分析试验。
Drilling practice has proved that the quality of solid teeth seriously affect the working life of the insert bit. As the range of strata to be used for inserts increases and the promotion of the use of high-edged wedge toothed bits, the working condition of the insert bit becomes even more burdensome, which sets a higher requirement on the quality of the solid teeth. In order to further analyze the factors that influence the quality of solid teeth and further explore the technological measures to improve the strength of solid teeth, we conducted a preliminary analysis and experiment with the main factors affecting the quality of solid teeth in cooperation with Shanghai No. 1 Petroleum Machinery Factory.
