ukulungiswa kwebhokisi
Kumanqanaba aphakathi kunye nasemva kokusetyenziswa kwe-oilfield, kunye nokwandiswa kwexesha lemveliso, inani lemisebenzi kunye ne-workovers liyanda, kwaye umonakalo we-casing uya kwenzeka ngokulandelelana. Emva kokuba i-casing yonakalisiwe, kufuneka ilungiswe kwangethuba, kungenjalo kuya kukhokelela kwiingozi ze-downhole.
1. Ukuhlolwa kunye nokulinganisa umonakalo we-casing
Imixholo ephambili yokuhlolwa kwe-casing yile: utshintsho lwe-diameter yangaphakathi ye-casing, umgangatho kunye nobukhulu bodonga lwe-casing, imeko yodonga lwangaphakathi lwe-casing, njl njl. Ukongeza, khangela kwaye unqume indawo ikhola yecasing, njl.
2. Ukulungiswa kwecasing ekhubazekileyo
I-casing eyonakeleyo ilungiswa ngotyando lweplastiki.
⑴Isixhobo seplastiki esimile okweperile (esikwabizwa ngokuba yi-tube expander)
I-expander ityhubhu ithotywa ukuya kwicandelo lequla eligqwethekileyo, kwaye inxalenye ekhubazekileyo iyandiswa ngokuthe ngcembe ngokuxhomekeke kumandla okuqhuma kwesixhobo sokomba. Umgama osecaleni onokuthi ukwandiswa ngexesha ngalinye ngu-1-2 mm kuphela, kwaye inani lokutshintshwa kwesixhobo likhulu.
⑵ Isibuni seCasing
Esi sixhobo sisetyenziswa ngakumbi kwaye sisimo esingcono.
I-casing shaper sisixhobo esikhethekileyo esisetyenziselwa ukulungisa i-deformation ye-casing equleni, njengokunciphisa kunye nokudandatheka, ukwenzela ukuba ubuyisele kwimeko ekufutshane nesiqhelo.
I-casing shaper iqukethe i-shaft eccentric, apho kukho i-roller ephezulu, ephakathi kunye nezantsi kunye nentloko ye-cone, kunye neebhola kunye neeplagi zokulungisa intloko ye-cone. Beka esi sixhobo kwi-deformed part of the casing, uyijikelezise kwaye usebenzise uxinzelelo olufanelekileyo, ukunyanzela intloko ye-cone kunye ne-roller ukucudisa udonga lombhobho okhubazekileyo we-casing yangaphandle kunye nomkhosi omkhulu osecaleni ukuze ufikelele kububanzi obuqhelekileyo kunye nokujikeleza.
I-Casing scraper: I-casing scraper isetyenziselwa ukususa nayiphi na idiphozithi, ukungalingani okanye i-burrs ngaphakathi kwe-oyile yequla le-oyile, ukuze kususwe imiqobo kwimisebenzi yexesha elizayo.
3. ingxowa yenkxaso-mali
Imingxuma enemingxuma egqobhokileyo okanye eqhekekileyo inokulungiswa ngamanyathelo enkxaso. I-diameter yangaphakathi ye-casing elungisiweyo kufuneka incitshiswe malunga ne-10mm, kwaye i-subsidy ingaba yi-10 ~ 70m kwisakhiwo esinye.
⑴ ulawulo lwenkxaso
Ubukhulu bombhobho we-subsidy ngokuqhelekileyo ngumbhobho wentsimbi ongenamthungo kunye nobukhulu bodonga obuyi-3mm, kunye ne-longitudinal ripples ezinkulu, kunye ne-0.12mm yelaphu yeglasi eshinyeneyo ejikelezwe kumbhobho, efakwe isamente nge-epoxy resin, kwaye umbhobho ngamnye unobude obuyi-3m. Xa isetyenziswa, ubude bombhobho ophantsi bunokudityaniswa kwisiza ngokweemfuno zokuyila, kwaye udonga lwangaphandle lugqunywe nge-epoxy resin ngaphambi kokungena equleni.
(2) Izixhobo zenkxaso
Ubukhulu becala yenziwe nge-centerizer, umkhono wokutyibilika, umhlaseli ongaphezulu, i-anchor ye-hydraulic, i-piston barrel, ipiston esisigxina, ipiston, intloko ephezulu, intonga yepiston, ityhubhu eyolula kunye ne-tube expander.
4. Casing ngaphakathi drill
Ukugrumba ngaphakathi kwe-casing kusetyenziswa ikakhulu ukulungisa amaqula e-oyile kunye nokusilela okukhulu kwi-downhole. Kunzima ukuphumelela ekujonganeni namaqula anzima kangaka ngeendlela eziqhelekileyo. Itekhnoloji yokuthintela i-Casing kufuneka isetyenziswe ukubuyisela amaqula afileyo kunye nokuphucula ukusetyenziswa kwe-oyile.
Ukugrumba ngaphakathi kwe-casing kukulungisa isixhobo sokuphambuka kubunzulu obuthile kwiqula le-oyile-amanzi, sebenzisa inqwelomoya ethambekele ukwakha kunye nokukhokela ukuphambuka, kwaye usebenzise ikhowuni yokugaya ukuvula ifestile kwicala le-casing, i-drill. umngxuma omtsha ngefestile, kwaye emva koko wehlise i-liner ukuyilungisa. Iseti entle yobugcisa. I-casing ngaphakathi kwetekhnoloji yokomba kukusetyenziswa kobuchwephesha bokwemba umkhombandlela ekulungisweni kwemithombo yeoli kunye namanzi.
Izixhobo eziphambili zokugaya ngaphakathi kwe-casing ziquka i-inclination setter, i-feeder inclination, i-cone yokugaya, i-drill bit, i-drop joint, iplagi ye-rubber ye-cementing, njl.
