摘要:

随着经济发展及矿产资源开发利用程度进一步提高，地质勘探向着深部、复杂地层发展，钻探施工钻孔也向着定向孔、分支孔的方向发展。地质目的对钻探工艺的要求越来越高，在控制钻孔轨迹方面也需越来越精准。本文就钻孔轨迹参数计算及成图作了详细介绍，阐述了钻孔轨迹相关概念及有关参数的计算方法；通过对Excel电子表格相关功能的研究，成功地将其应用到钻孔轨迹参数计算与处理分析中；通过对Solidworks三维制图软件的研究，成功地将其应用到钻孔轨迹监测及成图方面；通过实际工作案例验证了上述方法的可行性。

Abstract:

Along with the economic development and further improvement of mineral resources development and utilization, geological exploration is developing toward to deep and complex strata, drilling construction is also developing toward to the directional holes and branch holes. Higher requests are put forward for drilling technology to realize more comprehensive understanding of geological conditions, and the control of drilling trajectory also should be more and more accurate. In this paper, the drilling trajectory monitoring and mapping are described in detail， the related concepts of drilling trajectory and the calculation methods of the relevant parameters are elaborated. By the study on the related functions of Excel spreadsheet, which is successfully applied in the drilling trajectory parameters calculation and analysis; based on the research, Slidworks three-dimensional graphic software is successfully applied in drilling trajectory monitoring and mapping. The methods have been verified the feasibility in the actual work case.
