Monitoring of Technical Condition of the Wire Ropes of Drilling Rigs for Production and Exploratory Drilling of Oil and Gas Wells: Technology, Efficiency, Prospects


Annotation:

The issue of organization of monitoring technical condition of the wire rope — responsible bearing element of the rig structure is considered in the article. In the process of installation and round-trip operations during construction of wells, the wire rope is under high-intensity static and dynamic mechanical loads. In addition, the wire ropes of drilling rigs in the process of operation are subject to significant corrosion and friction wear. The proposed technology for monitoring technical condition of the wire ropes is based on the use of automated diagnostic devices that implement the magnetic method of nondestructive testing. This method is based on the registration of magnetically sensitive magnetic flux scattering sensors caused by the loss of the rope cross-section on the metal during operation due to corrosion and (or) the appearance of local defects (broken wire) from the active mechanical loads. The technology is described concerning monitoring technical condition of the wire ropes with the use of new diagnostic equipment — the INTROS-AVTO automated magnetic flaw detector. The results are given related to monitoring technical condition of the wire rope at one of the drilling rigs of OOO «Targin Burenie», which was carried out during the pilot-industrial tests of the automated INTROS-AVTO flaw detector. The strength of wire rope according to the diagnostics data was estimated. The efficiency of using automated magnetic flaw detector for ensuring trouble-free operation of the wire ropes of drilling rigs for production and exploratory drilling of oil and gas wells is illustrated.
