摘　　要：侧钻井在侧钻以后的施工过程中或在定向井扩划眼过程中,由于多种原因易出现新井眼,即井眼出现分叉,这使下钻、下套管、电测等后续作业难以进行,若重新填井侧钻则导致巨大的经济损失。中原油田在文188-14井井眼分叉处理过程中应用了三维井眼分叉处理技术,不但井眼分叉处理成功,而且成功地找到了原侧钻井眼,从而减少了经济损失,也为井眼分叉处理找到了一个新方法。A new wellbore is often made easily for many reasons during drilling or directional reaming after sidetracking, which make it difficult that include running back in holes, running casing, electrical logging, etc. Under this condition, if the wellbore was filled and a new one was sidetracked, an enormous economic loss would be made. In view of this situation, the 3-dimensional branching technology is employed during dealing with branching off in Wen-188-14 Well. The application shows that this technology make it possible to branch off successfully, find original wellbore, and reduce economic loss. Therefore, it would be a new method for dealing with branching.
