- Abstract
There are some limiting factors in operating of JX1-1-A platform development wells, such as the limited number of notch, concentrated well region, and frequent target adjustment for geological update. Taking account of the upper strata extremely soft, sliding difficulties in conglomerate layer, and inclination of risers, we designed directional well trajectory and added control points to optimize trajectory for a single well. With the application of preventive oblique, anti-collision around obstacles, gyro direction, segments of deviation for shadow vertical wells, and combined with preferable BHA and reasonable drilling parameters, a complete set of shallow and deep anti-collision technologies was formed. The drilling task of JX1-1-A platform was successfully completed by these technologies, which making a good foundation for the development of the platform and Bohai Oilfield.
