Iimpawu zomthungoibhokisikwayeimibhobho

Isingxobo se-oyile esingenamthungo, uphononongo lwe-oyile nerhasi ngesona sixa sikhulu sombhobho, sixhomekeke kwiqhina lenkunzi nelomazi elijijelwe ngaphakathi nangaphandle, liya kwenza umsebenzi wombhobho wentsimbi ophantsi komhlaba.I-oil well casing yindlela yokuphila yomgangatho wayo ichaphazela ngokuthe ngqo impumelelo yemisebenzi yokomba kunye nobomi benkonzo ye-oyile kunye negesi yamaqula, enxulumene nemimandla yeoli kunye neenzuzo zezoqoqosho zomenzi.

Ukungaphumeleli kwe-oyile enomthungo yenye yeengxaki eziphambili ekuhlangatyezwane nazo kwindawo nganye yeoli, ngakumbi phakathi kweyona ntsilelo inzima yejoyinti edityanisiweyo.Ngokwezibalo, ukungaphumeleli kwe-oyile ye-oyile kwenzeka malunga ne-64% yeengozi ezidityanisiweyo zengozi, eli nani liphezulu njenge-86%, ukukhusela i-oyile ye-oyile yokudibanisa i-threaded likhonkco elibuthathaka kwintambo ye-oyile, ngoko ke, ukwandisa uxhumano lwentambo. umgangatho yinto ephambili ekuqinisekiseni umgangatho wekholamu.I-oil casing threaded uxhulumaniso olusetyenziselwa ukusabalalisa uxinzelelo lumisela ngokuthe ngqo amandla omtya wokudibanisa.Ukusasazwa koxinzelelo lwamacandelo ophononongo, kungekuphela nje kubavelisi abalungiselela uyilo lwe-oyile yecasing, i-casing kunye netyhubhu esetyenziselwa ukuqikelela ukusebenza kubonelela ngesiseko, kodwa kunye nokukhokela ukhetho olufanelekileyo kunye nokusetyenziswa kwe-oilfield tubing kunye ne-casing nayo inereferensi ethile. ixabiso.

Isingxobo seplastiki kunye nengono yetyhubhu

Izikhonkwane ze-oyile ezingenamthungo zidityaniswe ngaphandle iqhina lendoda kunye nebhanti yebhanti ephothiweyo kunye isikhonkwane esidityaniswe ngeqhina lendoda nebhinqa kwindawo yoqhagamshelwano, engumphezulu we-helical, kwaye amandla okufaka ityhubhu ye-oyile anzima ngakumbi.Apart screwed contact pressure generated torque, kodwa nangenxa yoxinzelelo (self-weight of the oil casing), uxinzelelo (ngeoyile, igesi okanye ezinye izinto zosasazo ezibangelwa) yindima yemithwalo enjalo.I-oil casing i-joint force analysis ibandakanya izinto ezingahambelaniyo, i-geometric nonlinearity kunye nobunzima beemeko zoqhagamshelwano kunye nezinye iingxaki ezingabonakaliyo ziseka imodeli yezibalo epheleleyo kunye nechanekileyo, isisombululo sohlalutyo sinzima kakhulu.
