1. Isimiso sesakhiwo
Ipulaki yebhuloho elicindezela umlotha elibuyiselekayo liqukethe isivalo sesihlalo kanye nendlela yokukhonkwane, indlela yokukhiya neyokuvula, iswishi yomkhono oslayidayo kanye nomshini wokunqanda induku, okokufaka kanye nendlela yokuhlenga.
Ithuluzi lokusetha ikhebula noma ithuluzi lokumisa ipayipi likawoyela elisebenza ngaphansi kwamanzi lingasetshenziselwa ukuthumela ipulaki yebhuloho endaweni enqunywe kusengaphambili ukuze imiswe futhi ilahlwe, bese ukhipha ithuluzi lokusetha nelokuphakelayo, ufake ithuluzi lokuyithulula kupulaki yebhuloho yokukhama ebuyiselekayo, futhi qhuba umsebenzi wokukhama umlotha , Ngemva kokukhama umlotha, phakamisa ithubhu le-intubation bese ugeza umthombo ngemuva.Ngemva kokumiswa kokuqala kodaka, i-overshot ingehliswa ukuze idobe ipulaki yebhuloho.
2. Inqubo yomsebenzi
1. Ukusetha nokusebenza kokuvala kuyefana nomsebenzi ojwayelekile wokuvala.
2.Ngemva kokuba ipulaki yebhuloho elikhama umlotha isimisiwe, xhuma i-cannula ekhama umlotha phansi kwentambo yeshubhu bese ulehlisela emthonjeni, ulifake ku-mandrel yepulaki yebhuloho yokukhama umlotha, bese uyiphusha. i-valve yesilayidi.
3.Faka indawo yodaka lukasimende ngeloli likasimende ukuze usebenze ngokukhama umlotha.
4.Ngemva kokuba umlotha usukhanyiwe, phakamisa ngokushesha intambo yepayipi, ukhiphe ipayipi lokungena ukuze uvale i-valve yesilayidi, bese ugeza ngokushesha umthombo ukuze ugeze udaka lukasimende oweqile emthonjeni.Ngenxa yokuthi i-valve yesilayidi ivaliwe, udaka lukasimende ngaphandle kwesakhiwo noma ipayipi alikwazi ukugeleza libuyele emthonjeni, okuqinisekisa ikhwalithi kasimende kanye nomthelela wokuxhuma wodaka lukasimende, kufinyeze isikhathi sokuhlala sodaka lukasimende emthonjeni, futhi kunciphisa intambo yepayipi yokuqiniswa kukasimende.
5.Uma ungqimba olungaphezulu luxhashazwa, i-Retrievable Bridge Plug of Cement Squeeze isetshenziswa njengesivalo esivamile sepulaki yebhuloho futhi ingafakwa ekukhiqizeni ngokuqondile;uma ungqimba olungezansi lwembiwa, intambo yokuhlenga engavaliwe ifakwa emthonjeni ukuze kukhishwe ipulaki yebhuloho.Ngemva kokuba ipulaki yebhuloho isikhishiwe, beka izicathulo zokugaya phansi emthonjeni ukuze ubhoboze ipulaki likasimende.Njengoba zingekho izingxenye zensimbi, ukubhoboza nokugaya kulula.
3. Izici zobuchwepheshe
1. Indlela yokusetha eguquguqukayo: Ipulaki yebhuloho ingathunyelwa esimisweni ngethuluzi lokusetha uhlobo lwekhebula noma ithuluzi lokusetha elisebenza nge-hydraulic, futhi ithuluzi lokusetha elifanelekile lingakhethwa ngokuya ngezimo ezithile zomthombo.
2. Ukulawula ukulungiselelwa okunembile: Amandla okusetha epulaki yebhuloho alawulwa yi-tension rod (ring), eqinisekisa ukulungiselelwa okuphephile nokuthembekile kwepulaki yebhuloho.Ngesikhathi esifanayo, iqinisekisa ukuthi ithuluzi lokusetha lingakhishwa ngokuphepha emthonjeni ngaphansi kwezimo eziyinkimbinkimbi.
3. Idizayini enokwethenjelwa yokulwa ne-jamming: Ingxenye yesiliphu yamukela isakhiwo sokushelela esakhelwe ngaphakathi, futhi ipulaki yebhuloho akulula ukubhekana nokuphikiswa nokugxumeka lapho iphakanyiswa futhi yehliswa ku-shaft.Ngemva kokusetha, iziliphu zepulaki yebhuloho kanye neshubhu yenjoloba zigxiliswa ngokuzenzakalela, futhi zingasetshenziswa ngokuphepha emithonjeni nganoma yikuphi ukuthambekela kanye nemithombo evundlile.
4. Indlela ehlukile yokunamathisela okuhange ngayo: Ipulaki yebhuloho isebenzisa inhlanganisela ehlakaniphile yeziliphu, ama-slip cones, namasilinda angaphandle ashelelayo.Inomthamo omuhle wokuthwala ingcindezi yezinhlangothi ezimbili futhi ingasetshenziswa kuma-casings wamazinga ahlukahlukene.
5. Indlela ephephile yokuvula: Ukuvalwa kwepulaki yebhuloho kwenziwa isinyathelo ngesinyathelo ngokulandelana kwendlela yokukhiya, indlela yokuvala, kanye nendlela yokushelela.Kungakhathaliseki ukuthi izingcindezi ezingaphezulu neziphansi zepulaki yebhuloho zilinganiselwe, amandla adingekayo okuvula mancane kakhulu.
6. Kulula ukubhoboza nokugaya ipulaki yomlotha: ngemva kokusebenza kokucindezela komlotha kwepulaki yebhuloho egaya kabusha egaywa ngomlotha, ipulaki yebhuloho ingakhishwa, futhi kulula ukuyibhoboza nokugaya ipulaki yomlotha.
7. Ikwazi ukubhola okuthile: ipulaki yebhuloho inesakhiwo esihlangene, isakhiwo esingaphezulu senziwe ngezinto ezikwazi ukubhola kangcono, futhi indlela yokukhiya yangaphakathi ingaphezulu kwepulaki yebhuloho, ngisho noma ipulaki yebhuloho ingakwazi ukudotshwa ngenxa izizathu ezingavamile, kusengaba lula ukukhipha.
