摘　　要：由于井眼轨迹形成过程受诸多因素影响,较为精确地解释和描述动力学系统的行为,需要对影响动力学系统的诸多因素进行分析。在对井眼轨迹的影响因素进行详细分析的基础上,重新划分和定义了井眼轨迹的影响因素。并客观地将井下因素进行合理分类,按其存在的性质分为确定性因素、随机因素和模糊因素。然后针对影响因素的来源及其特征进行系统的定性描述,以及根据不同影响因素的性质给出了应采用的相应数学处理方法。Because of many influence factors existing in the process of well trajectory construction, and in order to more accurately explain and describe the dynamics system behavior, many influencing factors which influences dynamics system needed to be analyzed. This paper analyzed the influence factors of well trajectory in details, and classified and defined the influence factors, and the downhole factors was classified rationally into decided factor, random factor and fuzzy factor based on the in-being characteristics, and then definitely described the source and its characteristic of influence factor, and put forward corresponding mathematic treatment method based on the characteristic of different influence factors.
