Enye-ipasi eDityanisiweyo yoMgcini weSamente
Usetyenziso oluphambili
YCGZ - 110
Ipasi enye eDityanisiweyo yokuGcina iSamente isetyenziselwa ikakhulu ukuplaga okwethutyana kunye nokusisigxina okanye ukufakwa kwesamente okwesibini kwi-oyile, igesi kunye namanzi.I-sement slurry icinezelwe kwisithuba se-annular ngokusebenzisa i-retainer kwaye idinga ukutywinwa.Icandelo le-cemented well or fractures kunye ne-pores engena kwi-formation isetyenziselwa ukufezekisa injongo yokucoca kunye nokulungisa ukuvuza.
Ulwakhiwo kunye noMgaqo wokuSebenza
Ulwakhiwo:
Ibandakanya indlela yokumisela kunye nomgcini.
UmGaqo wokuSebenza:
Ukuseta itywina: Xa umbhobho weoyile ucinezelekile ukuya kwi-8-10MPa, isikhonkwane sokuqala siyanqunyulwa, kwaye ipiston enezigaba ezibini ityhala isilinda ezantsi ngokulandelelana, kwaye kwangaxeshanye yenza ukutyibilika okuphezulu, ikowuni ephezulu, ityhubhu yerabha. kunye nekhowuni esezantsi ezantsi, kwaye amandla okuqhuba afikelela Malunga ne-15T, emva kokugqitywa kokusetwa, iqhosha lokulahla liyanqunyulwa ukuze kubonwe ukuhla.Emva kokuba isandla siwe, umbhobho ophakathi ucinezelelwe kwakhona kwi-30-34Mpa, isikhonkwane sesihlalo sebhola sinqumla umbhobho weoli ukukhulula uxinzelelo, kwaye isihlalo sebhola siwela kwibhaskithi yokufumana, kwaye ikholamu yombhobho icinezelwe. phantsi ngo-5-8T.Umbhobho weoyile uxinzelelwe kwi-10Mpa kwaye ucinezelwe ukujonga isitywina, kwaye kufuneka ukuba ufunxe amanzi kwaye ucofe inaliti.
Ukulumkela
①Lo mtya wombhobho awuvumelekanga ukuqhagamshela izixhobo zokugqitha ngaphandle.
②Iibhola zetsimbi zokumisela azivumelekanga ukuba zibekwe ngaphambili, kwaye isantya sokugaya sinqunyelwe ngokungqongqo ukuthintela uxinzelelo olubangelwa yisantya esiphezulu sokugaya, ukwenzela ukuba i-coating ephakathi inokumiselwa.
③ Ukukrazula kunye nokugungxulwa kufuneka kwenziwe kumsebenzi wokuqala ukuze kuqinisekiswe ukuba udonga lwangaphakathi lwe-casing alunasikali, isanti kunye neengqungquthela, ukwenzela ukuba kuthintelwe ukungaphumeleli kokumiswa okubangelwa isanti kunye neengqungquthela ezivimba umjelo wesixhobo sokumisela.④Emva kokuba isiphelo esisezantsi somgcini sicinezelwe, ukuba ukuba isiphelo esiphezulu sifuneka ukuba sicinezelwe, isiphelo esiphezulu somgcini kufuneka sicinezelwe emva kokuba isamente kwisiphelo esisezantsi siqiniswe.
Iimpawu zobuGcisa
1. Ukumiselwa kunye nokukhutshwa komtya wombhobho kugqitywe ngexesha elinye, elilula ukusebenza kwaye linomsebenzi omncinci.Emva kokusebenza kwe-extrusion, inxalenye engezantsi inokuvalwa ngokuzenzekelayo.
2. Uyilo oluvulekileyo lombhobho we-intubation kunye noyilo oluvulekileyo lwe-cement retainer lunokuthintela ngokufanelekileyo ukuvinjelwa kwesanti kunye nokungcola, kunye nokuthintela ukutshintshela ekusebenzeni kakubi.
