Abstract:

Drilling for opening a sidetrack window on the casing itself is a very important stage in the construction of sidetracking unconventional diameter wells from a conventional master well. This article presents and analyzes the typical complex and incidents that possibly occur during drilling for opening a sidetrack window on the casing before the drilling unconventional diameter sidetrack well. On this basis, and combined with the identifying the influence factors and the principles of sidetrack position choice, build the diagram calculating and choosing the reasonable position of sidetrack position to minimize the possibility of the complex, incidents when drilling for opening a sidetrack window on the casing.
