Products & Services Drilling
 | Increase the drainage radius and area of borehole and realize the stimulation. |  | |
| Radial and multi-lateral drilling in vertical wells instead of the functions of horizontal branch wells and directional sidetracking. | ||
| Penetrate contaminated area near wellbore instead of conventional perforation. | ||
| Advanced acidization. | ||
| Realize directional water injection. | ||
| Reduce squeeze pressure and improve the effect of profile control and water shutoff. | ||
| Realize advanced obstruction removal. | ||
| Short operating period, 4 laterals radial drilling completed within 2 days and whole operation completed within 5 days, equivalent to 1/3 the time of window sidetrack drilling. | ||
| No need of slurry and no damage on reservoirs. | ||
| Less fluid (only 10-20 cubic meters needed in four laterals of one layer) | ||
| Less damage on casing than perforation, and strength remains unchanged. |
