Buyini ubuchwepheshe be-Thru-tubing Inflatable Bridge Plug?

Isingeniso sobuchwepheshe: Ngesikhathi senqubo yokukhiqiza, imithombo kawoyela negesi idinga ukwenza ukufakelwa kwezingxenye noma eminye imisebenzi yokufakelwa ngenxa yokwanda kokuqukethwe kwamanzi kawoyela ongahluziwe. Izindlela zangaphambili ukufaka umshini wokubhoboza noma umshini wokufakelwa, ukubulala umthombo, ukukhipha ipayipi lokukhiqiza, nokufaka ipulaki yebhuloho noma umjovo I-Cement ivala i-aquifer, bese kukhiqizwa ipayipi likawoyela lokukhiqiza. Lobu buchwepheshe besikhathi esidala abugcini nje ngokuba nezindleko zokukhiqiza eziphezulu, kodwa futhi buphinde bungcolise ungqimba lokukhiqiza uwoyela futhi, buthinte ukukhiqizwa. Ngesikhathi esifanayo, kunzima ukulawula ukujula kwepulaki yebhuloho. I-Baker Oil Tool muva nje iphakamise ubuchwepheshe obusha bokufakelwa kwelakhi likawoyela obubizwa ngokuthi "ubuchwepheshe bokukhulisa ipulaki yebhuloho likawoyela elibekwe ngekhebula." Lobu buchwepheshe bunezidingo zenqubo eziphansi, izindleko eziphansi, umphumela omuhle futhi ipulaki yebhuloho ingaphinde isetshenziswe. Umphumela wezomnotho usobala kakhulu lapho usebenza olwandle.

Izici zobuchwepheshe: Akukho mishini yokubhoboza noma yokulungisa, ipayipi likawoyela noma imishini yamapayipi ahlanganisiwe edingekayo lapho kusethwa ipulaki yebhuloho. Ukungawubulali umthombo kugwema ukungcoliswa kabusha kwengqimba kawoyela. Konga isikhathi esingaphezu kwengxenye uma kuqhathaniswa namathuluzi amadala. Ifakwe i-magnetic positioner ukulawula ngokunembile ukujula kokungena. Ihambisana kahle futhi ingasetshenziswa nanoma yiluphi uhlelo lwekhebula. Ingalawulwa kude, okuyinto ezuzisa kakhulu ezindaweni eziningi njengezinkundla zokubhoboza ezingafaneleki imisebenzi yamapayipi ahlanganisiwe. Ingadluliswa ngemininingwane ehlukene yamapayipi, i-casing, ipayipi lokubhoboza, noma ibekwe kuzo (bheka ithebula elingezansi). Ingamelana nomehluko wokucindezela ongu-41.3 MPa kuzo zombili izinhlangothi. Ngemva kokuthi ipulaki yebhuloho isethiwe, usimende ungafakwa epulaki yebhuloho ukuze uyiguqule ibe ipulaki yebhuloho ehlala njalo. Imelana nomehluko omkhulu wokucindezela. Amapayipi ahlanganisiwe noma intambo yocingo angasetshenziswa ukubuyisa nokukhipha.

Isimiso sokusebenza: Okokuqala xhuma amathuluzi ngokulandelana okuboniswe ngezansi bese wehla emthonjeni. I-magnetic locator ivumela ipulaki yebhuloho ukuthi yehliswe iye ekujuleni okuthembekile. Inqubo yokusebenza yesistimu inezinyathelo ezinhlanu: ukudilika, ukunwetshwa, ukucindezela, ukukhululeka kanye nokubuyiselwa. Uma kutholakala ukuthi indawo yepulaki yebhuloho ilungile, amandla anikezwa kuphampu yokunwetshwa ephansi ukuze isebenze. Iphampu yokunwetshwa ihlunga uketshezi olubulala kahle ngesihlungi bese ilumunca ephampu ukuze ilucindezele, iluguqule lube uketshezi lokunwetshwa bese ilupompa emgqonyeni werabha wepulaki yebhuloho. Ukusebenza kokusetha ipulaki yebhuloho kulawulwa futhi kulandelelwa ngokugeleza kwamanje kumonitha yomhlaba. Uma uqala ukupompa uketshezi kupulaki yebhuloho, inani lamanje lokuqala libonisa ukuthi ithuluzi lokusetha seliqalile ukusebenza. Lapho inani lamanje landa ngokuzumayo, libonisa ukuthi ipulaki yebhuloho selikhulile futhi laqala ukucindezela. Lapho inani lamanje lemonitha yomhlaba lincipha ngokuzumayo, libonisa ukuthi uhlelo lokusetha selukhululiwe. Amathuluzi okusetha nezintambo zishiywa zikhululekile futhi zingaphinde zisetshenziswe. Ipulaki yebhuloho elibekiwe lingamelana ngokushesha nomehluko wokucindezela okuphezulu ngaphandle kwesidingo sokuthululwa komlotha noma usimende owengeziwe. Ipulaki yebhuloho elibekiwe lingatholakala ngokungena emgodini ngemishini yekhebula ngesikhathi esisodwa. Ukulinganisa umehluko wokucindezela, ukukhulula kanye nokubuyisa konke kungaqedwa ngohambo olulodwa.
