Description

Technical Field

[0001] The utility model belongs to the technical field of petroleum development logging instruments, in particular to an electrode system clamp for an eight-way laterolog instrument which is easy to install and disassemble. Background Art

[0002] When calibrating and checking the eight-way lateral logging instrument on the Dual Induction Eight Laterograph, a calibration clamp must be installed on the electrode system at the end of the coil system and then connected to a resistance box simulating the formation. The electrode system consists of four electrodes. The current clamp uses screws to control four steel rings. During installation, each of the four rings, approximately 45 cm long, must be loosened individually with a screwdriver, fitted over the four electrodes, and then tightened. This presents several challenges: First, installation takes approximately seven minutes, and the clamp must be repeatedly removed and reinstalled during instrument inspection and fault diagnosis, which is time-consuming and labor-intensive, significantly impacting maintenance efficiency. Second, if the coil system is equipped with centralizers at both ends, the large diameter of the centralizers prevents the clamps from being fitted even at their maximum size. Third, the steel rings do not fit properly with the electrode system, resulting in poor contact and affecting calibration accuracy. Utility Model Content
