根据动力钻具在水平并中的造科特性，用几何分析方法推导出不带稳定器双弯动力钻具和带稳定里双弯动力钻具造料车的计算公式。根据这些公式，可对在水平共中使用的不同结构、不同几何尺寸的双奇功力钻具的造科率进行分析预测，也可用来指导动力钻具外形结构的设计和加。。此外，还对华弯动力钻具和异向双弯动力钻具（DTU）造科率的计算公式和适用条件进行了分析讨论，并对计算的单、双弯动力钻县造科率进行了现场验证。实粘结果说明，这种计算方法有一定的实用价值。
According to the characteristics of horizontal and vertical dynamic drilling tools, this paper deduces the formula of double curved bending drill with stabilizer and double curved bending drill with stable force by geometric analysis method. Based on these formulas, it is possible to analyze and forecast the rate of establishment of double-odd-power drilling tools of different structures and geometries used in horizontal co-ordination, and also to guide the design and addition of the shape structure of the power drill. . In addition, the calculation formula and applicable conditions of the rate of the establishment of the Chinese curved power drill and the double-curved power drill (DTU) are also analyzed and discussed, and the calculated rates of drilling of the single and double curved power drilling counties Field verification. Real sticky results show that this method of calculation has some practical value.
