| Abstract: | Main factors affecting the directional accuracy are analyzed in this paper. The theoretical formulas to calculate the deflection ability and azimuth change of the dynamical tool are also given. Meanwhile, the formula to calculate the azimuth change is simplified. The field applications in 6 wells in Jiangsu Oilfield show that the anticipated value derived by using those formulas are well fit with the practical ones. The problems of the bottom hole azimuth inaccuracy in small deviation well and orientation in shallow formation are solved basically. |
