发明名称 RADIAL INDEXING COMMUNICATION TOOL AND METHOD FOR SUBSURFACE SAFETY VALVE WITH COMMUNICATION COMPONENT
摘要 A communication tool apparatus is described which is adapted to provide selective communication of control fluid through a downhole tool, such as a safety valve. The downhole safety valve is a tubing retrievable subsurface safety valve ("TRSSSV"). The communication tool may be run downhole and within the TRSSSV. Once within the TRSSSV, the communication tool apparatus activates a cutting device within the TRSSSV such that communication of control fluid through the TRSSSV is possible. A replacement safety valve run on a wireline may then be inserted into the TRSSSV and be operated via the control fluid line, as a new communication path created by the communication tool described herein. A method of using the communication tool apparatus is also described.
