Tool for locating and plugging lateral wellbores

摘要

A tool used for treating and/or maintaining a wellbore that includes acoustic transducers for locating a lateral wellbore that intersects a primary wellbore. The tool include a sensor to sense water and/or gas, and if the water and/or gas enters the primary wellbore from a lateral wellbore, the lateral to primary intersection can be identified by correlating information from the sensor and acoustic transducers. If needed, the tool can be used to plug the water and/or gas supplying lateral wellbore. The tool may include a bendable sub portion for orienting a portion of the tool for insertion into the lateral wellbore and a plug section for plugging the lateral wellbore after insertion therein.
