METHOD OF EVALUATING BONDING STATE BETWEEN TUBE AND BONDING AGENT, AND MINE EQUIPMENT INSTALLED IN TUBE

摘要

PPROBLEM TO BE SOLVED: To provide a method and a device for analyzing a bonding state of fixing a casing inside a drilling well. PSOLUTION: The figure herein shows a mine equipment 40 useful for evaluating the bonding state between a tube and a bonding agent. The tube is the mine casing 36 installed in the drilling well 32 penetrated through an underground layer 38, in Fig.8. The cement bonding agent comprises cement 44, and is used for separating a layer inside the underground layer 38 and for fixing the casing 36 to the drilling well 32. The mine equipment 40 is suspended inside the drilling well 32 by a cable 34, and the cable 34 is supported optionally by a ground surface pulley 35. The cable 34 not only serves as a means for making the mine equipment 40 go downwards in the drilling well 32, for supporting it, and for making it go up to a ground surface, but also serves as a communication line between the equipment 40 and the ground surface 45. An information processing system (IHS) 47 is connected to the mine equipment 40 via the cable 34. PCOPYRIGHT: (C)2007,JPO&INPIT
