定向钻进技术在黑龙江金厂矿区的应用

Application of Directional Drilling Technology in Jinchang Mining Area of Heilongjiang

摘要:

黑龙江省金厂矿区金矿体呈倾向南西的筒状产出，向西南方向侧伏。由于筒体切面范围小，故钻孔布设密度较大，地表钻孔布设位置易发生偏差，往往达不到预期钻进目标。为此引进了定向钻进技术，有效地控制了钻孔轨迹，提高了钻进效率，并且可以在此基础上开展“一基多孔”，有效控制该区矿体的形态。主要介绍了定向钻进应用中的影响因素及技术措施。

Abstract:

The gold orebody shows cylindrical output with small section area in Jinchang mining area of Heilongjiang Province, the location deviation is common for the densive borehole distribution. The directional drilling technology is introduced to control the drilling trajectory, which improves drilling efficiency and develops branch holes to learn the morphology of ore body. The paper introduces some affecting elements and the technical measures in the application of directional drilling.
