The　circumferential　guide　wave　can　effectively　evaluate　the　damage　of　pipe　or　the　cementation　quality　between　pipe　and　peripheral　medium.　In　this　research,　the　state　matrix　method　is　applied　to　derive　the　circumferential　SH　waves　dispersion　equation　of　semi-infinite　domain　cement　clad　hollow　circular　pipe　of　steel　matrix　in　cylindrical　coordinate　system.　By　combining　the　orthogonal　basis　of　Legendre　and　Laguerre　polynomial　series,　the　circumferential　SH　waves　dispersion　curve　of　semi-infinite　domain　clad　hollow　circular　pipe　is　numerically　calculated.　To　investigate　the　interaction　between　circumferential　SH　waves　and　various　cement　bonding　defects,　a　simulation　model　of　the　cemented　casing　structure　was　established　using　the　finite　element　software　ABAQUS.　The　model　was　designed　to　vary　the　defect　parameters,　providing　a　comprehensive　understanding　of　cementing　quality　in　cementing　casing.　Based　on　the　numerical　calculation　results,　it　is　concluded　that　the　amplitude　of　the　circumferential　SH　wave　increases　with　the　increase　of　the　circumferential　angle　of　the　cement　bonding　defect.　This　approach　serves　as　a　basis　for　evaluating　the　effectiveness　of　circumferential　SH　waves　in　identifying　cement　bonding　defects.　Copyright　©　2023　Gong,　Lyu,　Song,　Gao　and　He.
