Buyini ubuchwepheshe be-Thru-tubing Inflatable Bridge Plug?

Isingeniso sobuchwepheshe: Phakathi nenqubo yokukhiqiza, imithombo kawoyela negesi idinga ukwenza ukuxhuma kwesigaba noma eminye imisebenzi yokusebenzela ngenxa yokwanda kokuqukethwe kwamanzi kawoyela ongahluziwe. Izindlela ezedlule ukufaka umshini wokumba noma umshini wokusebenza, ukubulala umthombo, ukukhipha ishubhu lokukhiqiza, nokufaka ipulaki yebhuloho noma umjovo Usimende uvala i-aquifer, bese kukhiqizwa ipayipi likawoyela lokukhiqiza. Lobu buchwepheshe obudala abunayo nje kuphela izindleko eziphezulu zokukhiqiza, kodwa futhi ngokungenakugwemeka bungcolisa ungqimba olukhiqiza uwoyela futhi, kuthinte ukukhiqizwa. Ngesikhathi esifanayo, kunzima ukulawula ukujula kwepulaki yebhuloho. I-Baker Oil Tool isanda kuphakamisa ubuchwepheshe obusha bokuxhuma ungqimba lukawoyela obubizwa ngokuthi "ubuchwepheshe bepulaki yebhuloho lekhebula lesethi kawoyela yokwandisa." Lobu buchwepheshe bunezidingo eziphansi zenqubo, izindleko eziphansi, umphumela omuhle kanye nepulaki yebhuloho ingagaywa kabusha. Umphumela wezomnotho ubonakala kakhulu uma usebenza olwandle.

Izici zobuchwepheshe: Akukho mshini wokubhoboza noma umshini wokusebenza, ipayipi likawoyela noma impahla yokufaka amashubhu ahlanganisiwe edingekayo lapho usetha ipulaki yebhuloho. Ukungawubulali umthombo kugwema ukungcoliswa kabusha kongqimba lwamafutha. Ilondoloza isikhathi esingaphezu kwesigamu uma kuqhathaniswa namathuluzi esikhathi esidala. Ifakwe indawo kazibuthe ukuze ilawule ngokunembile ukujula kokungena. Ukuhambisana okuhle futhi kungasetshenziswa nanoma yiluphi uhlelo lwekhebula. Ingalawuleka ukude, okuzuzisa kakhulu ezindaweni eziningi njengezinkundla zokumba ezingafanele ukusebenza kwamashubhu ahlanganisiwe. Ingadluliswa ngokucaciswa okuhlukene kwamashubhu, i-casing, ipayipi lokubhoboza, noma isethwe kuwo (bheka ithebula elingezansi). Iyakwazi ukumelana nomehluko wengcindezi engu-41.3 MPa nhlangothi zombili. Ngemva kokusetha ipulaki yebhuloho, usimende ungajovwa kupulaki yebhuloho ukuze uyiguqule ibe ipulaki yebhuloho ehlala njalo. Melana nomehluko omkhulu wengcindezi. Ishubhu eligoqiwe noma intambo yocingo ingasetshenziswa ukuze ilulame futhi ikhishwe.

Isimiso sokusebenza: Qala ngokuxhuma amathuluzi ngendlela eboniswe ngezansi bese wehlela emthonjeni. Indawo kazibuthe ivumela ipulaki yebhuloho ukuthi yehliselwe ekujuleni okuthembekile. Inqubo yokusebenza yesistimu inezinyathelo ezinhlanu: i-downhole, ukunwetshwa, ukucindezela, ukukhululeka kanye nokululama. Uma kunqunywa ukuthi indawo yepulaki yebhuloho ilungile, amandla anikezwa iphampu yokunweba ephansi ukuze isebenze. Iphampu yokwandisa ihlunga uketshezi olubulala kahle ngesisefo bese ilumunca epompo ukuze ilicindezele, iluguqule lube uketshezi olunwetshiwe bese lulupompa emgqonyeni werabha wepulaki yebhuloho. Umsebenzi wokusetha ipulaki yebhuloho uyalawulwa futhi ulandelelwa ngokugeleza kwamanje kusiqapha saphansi. Uma uqala ukumpompa uketshezi kupulaki yebhuloho, inani lamanje lamanje libonisa ukuthi ithuluzi lokusetha seliqalile ukusebenza. Lapho inani lamanje likhuphuka ngokuzumayo, libonisa ukuthi ipulaki yebhuloho inwetshiwe futhi yaqala ukucindezela. Lapho inani lamanje le-monitor yomhlabathi liyancipha ngokuzumayo, libonisa ukuthi uhlelo lokusetha lukhululiwe. Amathuluzi okusetha kanye nezintambo zishiywa zikhululekile futhi zingagaywa kabusha. Ipulaki yebhuloho emisiwe ingamelana ngokushesha nomehluko wengcindezi ephezulu ngaphandle kwesidingo somlotha owengeziwe noma usimende. Ipulaki yebhuloho elimisiwe lingatholwa ngokungena emthonjeni ngezinto zekhebula ngesikhathi esisodwa. Ukulinganisa umehluko wengcindezi, ukukhululeka kanye nokululama konke kungaqedwa ohambweni olulodwa.
