Method of locating a cementing plug in a subterranean well |
摘要 |
<p>A method which, in an embodiment, permits a location and/or displacement of a cementing plug (42) to be determined during a cementing operation. One or more pressure pulses are transmitted through a displacement fluid (40) which is being used to pump the plug (42) through a casing string (12). The pressure pulses are reflected off of the plug (42) and received by a pressure sensor (26). Information regarding the timing of the reflected pressure pulses may be used to determine the location and/or displacement of the plug (42). <IMAGE></p> |
