1. Isimiso sesakhiwo
Ipulaki yebhuloho lokucindezela umlotha elingabuyiselwa liqukethe isivalo sesihlalo kanye nendlela yokubopha, indlela yokukhiya nokuvula, iswishi yesikhafu esishelelayo kanye nendlela yokuvimbela ukunamathela, i-intubation kanye nendlela yokusindisa.
Ithuluzi lokusetha ikhebula noma ithuluzi lokusetha ipayipi likawoyela lingasetshenziswa ukuthumela ipulaki yebhuloho endaweni enqunyiwe yokusetha nokulahlwa, bese ukhipha ithuluzi lokusetha nokondla, ufake ithuluzi lokufaka ipayipi epulaki yebhuloho lokucindezela umlotha elitholakalayo, bese wenza umsebenzi wokucindezela umlotha. Ngemva kokucindezela umlotha, phakamisa ipayipi lokufaka ipayipi bese ugeza umthombo. Ngemva kokusetha kokuqala kwe-mortar, i-overshot ingancishiswa ukuze kukhishwe ipulaki yebhuloho.
2. Inqubo yomsebenzi
1. Ukusetha kanye nokusebenza kokuvula kufana nokusebenza kokuvala okuvamile.
2. Ngemva kokuthi ipulaki yebhuloho lokucina umlotha isisethiwe, xhuma i-cannula yokucina umlotha phansi kwentambo yepayipi bese uyibeka phansi kwe-wellbore, uyifake ku-mandrel yepulaki yebhuloho lokucina umlotha lohlobo lokubuyisela, bese ucindezela i-valve yesilayidi.
3. Faka iloli yesamente esikhundleni se-slurry yesimende ukuze kusebenze ukucinywa komlotha.
4. Ngemva kokuba umlotha usucindezelwe, phakamisa ngokushesha intambo yepayipi, khipha ipayipi lokufaka intubhu ukuze uvale ivalvu yesilayidi, bese ugeza ngokushesha umthombo ukuze ugeze udoti wesamente owengeziwe uphume emgodini womthombo. Ngenxa yokuthi ivalvu yesilayidi ivaliwe, udaka lukasimende olungaphandle kokwakheka noma ipayipi alukwazi ukubuyela emuva emgodini womthombo, okuqinisekisa ikhwalithi yokuqinisa kanye nomphumela wokuxhuma kodaka lukasimende, kunciphisa isikhathi sokuhlala kodaka lukasimende emgodini womthombo, futhi kunciphisa intambo yepayipi yokuqinisa udaka lukasimende.
5. Uma ungqimba olungaphezulu lusetshenziswa, i-Retrievable Bridge Plug of Cement Squeeze isetshenziswa njengesivalo se-bridge plug esivamile futhi ingafakwa ekukhiqizweni ngqo; uma ungqimba olungezansi lumbiwa, intambo yokusindisa engavaliwe ifakwa emthonjeni ukuze kususwe i-bridge plug. Ngemva kokuba i-bridge plug ikhishwe, beka izicathulo zokugaya phansi emthonjeni ukuze ubhoboze i-cement plug. Njengoba zingekho izingxenye zensimbi, ukubhoboza nokugaya kulula.
3. Izici zobuchwepheshe
1. Indlela yokusetha eguquguqukayo: Ipulaki yebhuloho ingathunyelwa kusethingi ngethuluzi lokusetha uhlobo lwekhebula noma ithuluzi lokusetha i-hydraulic, futhi ithuluzi lokusetha elifanele lingakhethwa ngokuya ngezimo ezithile zomthombo.
2. Ukulawula okunembile kokusetha: Amandla okusetha epulaki yebhuloho alawulwa yinduku yokucindezela (indandatho), eqinisekisa ukusethwa okuphephile nokuthembekile kwepulaki yebhuloho. Ngesikhathi esifanayo, kuqinisekisa ukuthi ithuluzi lokusetha lingasuswa ngokuphephile emgodini ngaphansi kwezimo eziyinkimbinkimbi.
3. Umklamo othembekile wokulwa nokugoba: Ingxenye yokugoba isebenzisa isakhiwo sokugoba esakhelwe ngaphakathi, futhi ipulaki yebhuloho akulula ukubhekana nokumelana nokugoba lapho iphakanyiswa futhi yehliswa emshafini. Ngemva kokusetha, ukugoba kwepulaki yebhuloho kanye neshubhu yerabha kufakwa phakathi ngokuzenzakalelayo, futhi kungasetshenziswa ngokuphephile emithonjeni enanoma yikuphi ukuthambekela kanye nemithombo evundlile.
4. Indlela yokubambelela ehlukile: Ipulaki yebhuloho isebenzisa inhlanganisela ehlakaniphile yama-slip, ama-slip cone, nama-slip outer cylinders. Inamandla amahle okuthwala ingcindezi ezinhlangothi zombili futhi ingasetshenziswa ezikhwameni zamazinga ahlukahlukene.
5. Indlela yokuvula ibhuloho ephephile: Ukuvula ibhuloho kwenziwa isinyathelo ngesinyathelo ngokulandelana kwendlela yokukhiya, indlela yokuvala, kanye nendlela yokushelela. Kungakhathaliseki ukuthi ingcindezi ephezulu nephansi yebhuloho ilinganisiwe, amandla okuvula adingekayo mancane kakhulu.
6. Kulula ukubhoboza nokugaya ipulaki lomlotha: ngemva kokusebenza kokucindezelwa komlotha kwepulaki yebhuloho eliphinda lisetshenziswe lokucinywa komlotha, ipulaki yebhuloho ingakhishwa, futhi kulula ukubhoboza nokugaya ipulaki lomlotha.
7. Yiba nokubhoboza okuthile: ipulaki yebhuloho inesakhiwo esincane, isakhiwo esingaphezulu senziwe ngezinto ezinokubhoboza okungcono, futhi indlela yokukhiya yangaphakathi iphezulu kwepulaki yebhuloho, noma ngabe ipulaki yebhuloho ayikwazi ukukhishwa ngenxa yezizathu ezingavamile, kusengaba lula ukuyibhoboza.
