Ukubonisa umlingani
I-single-ram shear blowout preventer (BOP) uhlobo olukhethekile lwe-BOP olusetshenziswa ezintweni zokulawula imigodi yokubhola uwoyela. Umsebenzi wayo oyinhloko ukusika ngokushesha izintambo zokubhola nokubopha ikhanda lomgodi kusetshenziswa i-ram eyodwa, okuyenza ilungele ukulawula ukuqhuma ezimweni eziphuthumayo eziphuthumayo. Nansi isifinyezo esicacile sezici zayo eziyinhloko:
1. Imisebenzi Eyinhloko
Umthamo Wokusika: Yakhelwe ngokukhethekile ukusika ipayipi lokubhola, izinduku zokubhola, noma amathuluzi asemgodini, ingasika ngamandla ipayipi lensimbi ngemizuzwana (ngisho nangaphansi komthwalo omkhulu), yahlukanisa ngokushesha umthombo wokucindezela wekhanda lomgodi.
Umthamo Wokusika: Yakhelwe ngokukhethekile ukusika ipayipi lokubhola, izinduku zokubhola, noma amathuluzi asemgodini, ingasika ngamandla ipayipi lensimbi ngemizuzwana (ngisho nangaphansi komthwalo omkhulu), yahlukanisa ngokushesha umthombo wokucindezela wekhanda lomgodi.
Umsebenzi Wokufaka: Ngemuva kokuhlanza, i-ram ivala ngokuzenzakalelayo ukuze kwakhiwe isikhwama esiphelele, ivimbela ukuhamba kwemifula (uwoyela, igesi, amanzi) nokulawula ingcindezi ephezulu emgodini.
2. Ukuklama Kwesakhiwo
Isakhiwo Esilula: Ifakwe i-shear ram eyodwa kuphela enamandla aphezulu (ivame ukwenziwa ngensimbi ye-alloy), okuholela esakhiweni esihlangene nokwethembeka okuphezulu.
Isakhiwo Esilula: Ifakwe i-shear ram eyodwa kuphela enamandla aphezulu (ivame ukwenziwa ngensimbi ye-alloy), okuholela esakhiweni esihlangene nokwethembeka okuphezulu.
Indlela Yokushayela: Ikakhulu i-hydraulically driven, enempendulo esheshayo kakhulu (isikhathi sokusebenza sivame ukuba <30 amasekhondi), iqinisekisa ukusebenza ngokushesha ezimeni eziphuthumayo.
Isilinganiso Sokucindezela: Yakhelwe ukubekezelela ingcindezi kusuka ku-70MPa kuye ku-140MPa (cishe 10,000~20,000 psi), ilungele imigodi ejulile kakhulu noma izakhiwo ezinengcindezi ephezulu.
3. Izimo Zokusetshenziswa
Ukulawulwa Kwesigingci Esiphuthumayo: Kusetshenziswa njengomugqa wokugcina wokuzivikela ukuze kuxoshwe ngamandla i-tubing futhi kuvalwe isigingci lapho izivikeli ezijwayelekile ze-blowout zehluleka noma kwenzeka i-blowout.
Imisebenzi Eyingozi Kakhulu: Ifanele izindawo eziyingozi kakhulu njengokubhola emanzini ajulile, izigingci ezishisayo kakhulu nezinezingcindezi eziphezulu (HPHT), kanye nezigingci zikawoyela negesi eziqukethe isibabule.
Ukusetshenziswa Okuphumelelayo: Kuvame ukusetshenziswa njengemodyuli eyengeziwe kumasethi wokuvikela ukuvuza anemigudu eminingi (njengama-BOP amathathu) ukuze kuthuthukiswe ukuphepha jikelele.
4. Izinzuzo Eziyinhloko
Ukuphendula Ngokushesha: Umklamo owodwa wokusebenza wenza lula ukusebenza futhi ufinyeze isikhathi sokuphendula esiphuthumayo.
Ukwethembeka Okuphezulu: Azikho izingxenye ezingadingekile, izinga eliphansi lokwehluleka, kanye nokuzinza okuqinile ngaphansi kwezimo ezinzima.
Okonga Kakhulu: Usayizi ohlanganisiwe kanye nokugcinwa okulula, kufaneleka kumaphrojekthi okubhola anesabelomali esilinganiselwe kodwa adinga ukuvikelwa okuyisisekelo.
