弯曲和定向钻孔的设计计算——通用地质坐标系应用实例(之六)

Design-calculation of Curved or Direction Drilling——Applying of General Geological Coordinate System (6)

通用地质坐标系的似螺线法和圆弧线法为设计弯曲和定向钻孔提供了全定量计算的基础,并能在钻孔施工发生偏离时,指导选择钻孔纠斜方案.

Spiral and round curve methods of General Geological Coordinate System have established the basis on which the design of curved or directional drilling can be well calculated .Moreover , the methods could guide selection of deviation-correcting schemes when a drilling hole deviated its couse.
