Under normal conditions, T-type well takes:
No. | Working program | Working-hours (h) | Remarks |
1 | Depth correction | 3 | working hour is difference for different layer； |
2 | Azimuth adjusting | 3 | Working time is different according to the azimuth equipment； |
3 | Whipstock hanging | 0.5 | |
4 | Casing milling | 3 | The length of windows milling is 0.6-0.8m; The compound milling cone is fit for high-strength steel casing,such as P110、N80; |
5 | Building-up operation | 3 | The length of building-up hole is 4-6 meters； |
6 | Horizontal stage drilling | 40 | The average RPM of horizontal stage is 3m/h; T-type hole 90m, the purely drilling time maybe 30 hours. |
