Development of a technology and design of a removable whipstock assembly for drilling exploration wells using wireline core barrels
Background. During the drilling process, all wells undergo distortion to a greater or lesser extent. In a number of cases, the distortion of wells causes no significant effect on the results of drilling. Therefore, the actual position of the well shaft and bottom coordinates are not determined. This...

| description | Background. During the drilling process, all wells undergo distortion to a greater or lesser extent. In a number of cases, the distortion of wells causes no significant effect on the results of drilling. Therefore, the actual position of the well shaft and bottom coordinates are not determined. This applies to mapping, engineering-geological, blasting and other wells having a shallow depth. During deep-well drilling, especially at the final exploration stages, issues of drilling wells according to design trajectories acquire a greater importance and significant resources for their solution. The application of technical means for changing the direction of the well (whipstocks) is associated with a number of problems related to tripping operations.Aim. To reduce the time input needed for adjusting drilling trajectories by excluding tripping operations when conducting controlled drilling works.Materials and methods. The operating principles of various types of deflectors were studied. The results of investigating deflectors of continuous action are presented, along with means for adjusting drilling trajectories and optimizing the time required for controlled drilling works.Results. The conducted analysis revealed the direct proportion between the time spent on tripping operations and the costs incurred in controlled drilling.Conclusion. In order to reduce the time input needed for tripping operations during drilling, technological means should be developed to exclude them from the entire process. |
