The approaching of stem lifting load factor for directional well |
| |
| Abstract: | This paper analyzes the lifting calculation method for drilling stem at different sections of directional inclined well curve.In general consideration of the design and selection of a rig,the approach is made for lifting load factor based on cardinal number of drilling stem weight and the effectiveness of drilling stem lifting.A simplified calculation formula is obtained.The result shows that the simplified calculation formula is with a practical value for rig design and selection. |
