| 摘 要： | 介绍了国内外涡轮钻具和螺杆钻具所用涡轮减速器、螺杆减速器、少齿差齿轮减速器及行星齿轮减速器的工作原理、发展现状及各自的适用范围。根据我国油田的具体情况，近期我国可发展螺杆减速器（组成螺杆－涡轮组合钻具）。从长远的观点看，我国应发展涡轮钻具并研制行星齿轮减速器。

| Abstract: | The working principle, current status and application scope of the reducers for turbodrills and screwdrills at home and aboard, including the turbine reducer, screw reducer, differential gear reducer and planetary gear reducer, are introduced. In the light of the existing conditions of the domestic oilfields, it is recommended to develop the screw reducers in recent years and develop turbodrills and planetaly gear reducers in the future. |
