Izici ze-seamlessibhokisifuthiishubhu

Igobolondo likawoyela elingenamthungo, ukuhlola uwoyela negesi ngenani elikhulu kunawo wonke lepayipi, lithembele kubhande lebhande leduna nelensikazi elijijwa ngaphakathi nangaphandle, lizosebenza uchungechunge olujulile lwepayipi lensimbi elingaphansi komhlaba.Isikhwama semithombo kawoyela siyindlela yokuphila yekhwalithi yayo ithinta ngqo impumelelo yokusebenza kokumba kanye nempilo yesevisi yemithombo kawoyela negesi, ehlobene nezinkundla zikawoyela kanye nezinzuzo zezomnotho zomkhiqizi.

Ukwehluleka kwesikhwama samafutha angenamthungo kungenye yezinkinga ezinkulu okuhlangatshezwana nazo endaweni ngayinye kawoyela, ikakhulukazi phakathi kokwehluleka okubi kakhulu kwejoyinti elinentambo.Ngokwezibalo, ukwehluleka kwe-oyela casing kwenzeka cishe ku-64% wezingozi ezixhunywe ezingozini, ezifuywayo lesi sibalo siphezulu njenge-86%, ukuvikela i-oil casing threaded joints kuyisixhumanisi esibuthakathaka entanjeni ye-oil casing, ngakho-ke, ukwandisa uxhumano lwentambo. ikhwalithi iyisici esibalulekile ekuqinisekiseni ikhwalithi yekholomu.Izixhumanisi zentambo kawoyela ezisetshenziswa ekusabalaliseni ingcindezi zinquma ngokuqondile amandla eyunithi yezinhlamvu yokuxhuma.Ukusatshalaliswa kwengcindezi kwezingxenye zocwaningo, hhayi kuphela kubakhiqizi abakhulisa ukwakheka kwentambo yegobolondo likawoyela, i-casing kanye neshubhu esetshenziselwa ukubikezela ukusebenza kunikeza isisekelo, kodwa futhi ukuqondisa ukukhetha okufanele kanye nokusetshenziswa kwamashubhu enkundla kawoyela kanye ne-casing futhi kunereferensi ethile. inani.

I-plastic casing kanye nengono yeshubhu

Amajoyinti ekesi likawoyela angenamthungo ayibhande lendoda elithungelwe ngaphandle kanye nebhande lebhande lesikulufa esiluchungechunge sesifazane esihlanganiswe ibhande lesilisa nelensikazi libopha indawo yokuthintana, okuyindawo ene-helical, futhi amandla okufaka amashubhu kawoyela ayinkimbinkimbi kakhulu.Ingcindezi yokuxhumana ehlanganisiwe ekhiqizwe yi-torque, kodwa futhi nangenxa yengcindezi (isisindo somuntu siqu sebhokisi likawoyela), ingcindezi (ngamafutha, igesi noma enye imidiya ebangelwa) indima yaleyo mithwalo.I-oil casing i-joint force analysis ihilela ukungahambisani kwezinto ezibonakalayo, ukungafani kwejometri kanye yinkimbinkimbi yezimo zokungqubuzana kokuxhumana nezinye izinkinga ezingezona ze-nonlinear zisungula imodeli yezibalo ephelele futhi enembile, isisombululo sokuhlaziya sinzima kakhulu.
