Kunjani ukuhlolwa kwesitifiketi sokufaneleka kwe-V0-class bridge plug packer?

Ekuthuthukisweni nasekukhiqizweni kwemithombo yegesi yemvelo, ukulawulwa kwemithombo kanye nezidingo ze-HSE ziqinile kakhulu kunezo zemithombo yokukhiqiza uwoyela. Esinye sezici ezibalulekile lapha ukusebenza kokuvala okungenawo umoyaabapaki—izingxenye ezisebenza njengezinto eziyinhloko zokuvala phakathi kwamathuluzi okuqeda imbobo engaphansi.

Uma sibheka umthelela wezici ezifana nokulayisha izintambo okuyinkimbinkimbi kanye nokushintshashintsha kwezinga lokushisa ngesikhathi sokukhiqizwa kwemithombo yegesi yemvelo ekusebenzeni kokuvala nokuqinisa kwabapaki, indinganiso ye-ISO 14310 (elingana ne-API 11D1) ihlukanisa izitifiketi zabapaki ezihloselwe imithombo yegesi zibe amamaki ama-3. Ibanga le-V0, elihlanganisa ukuhlolwa kwegesi okuphakathi, ukulayisha kwe-axial, ukujikeleza kwezinga lokushisa, kanye nezinqubo ezikhethekile ze-zero-bubble, yibanga lokuqinisekisa eliyinkimbinkimbi kakhulu futhi eliqinile phakathi kwazo.

Imikhiqizo eqinisekiswe yi-V0 grade isebenza kokubili njengesivikelo sokukhiqizwa okuphephile kwemithombo yegesi yemvelo kanye nokubonakaliswa okuphelele kwamakhono obuchwepheshe abakhiqizi bamathuluzi okudonsa phansi. Phakathi kwe-packer yangaphandle esanda kwethulwa kanyeipulaki yebhulohoimikhiqizo, yonke igcizelela isici se-V0 njengesici esiyinhloko; noma kunjalo, abakhiqizi basekhaya abakayikhangi ngokusemthethweni imikhiqizo yezinga elifanayo.

Ngaphandle komklamo womkhiqizo onengqondo kanye nokukhiqizwa okunembile nokuqinile, ukusungulwa kwezinhlelo zokuhlola ilabhorethri kanye nezinhlaka zokuhlola nakho kuyisici esibalulekile semikhiqizo eqinisekisiwe yebanga le-V0. Uhlelo lokuhlola ukusebenza kwesitifiketi sezinga le-V0-class packer lusetshenziswa kakhulu ekuhlolweni kwesitifiketi sebanga le-V0 kanye nebanga le-API eliphansi. Lukhiqiza imidwebo yemvilophu yokusebenza elinganisiwe yabapaki, futhi kanye namaphakheji edokhumenti yombiko wokuhlola, kwakha ingxenye eyisihluthulelo esekelayo yokufaka isicelo sesitifiketi sebanga le-V0 semikhiqizo enjalo.

Manje ake sijwayelane nohlelo lokuhlola ukusebenza kwesitifiketi se-packer sekilasi le-V0.

Umklamo Wesakhiwo

Lesi sakhiwo sesistimu senzelwe isitifiketi sokuhlolwa sebanga le-V0, futhi singasekela nezitifiketi zokuhlolwa zamabanga aphansi (isb., i-V1-V3) ngaphansi kwe-V0. Uhlelo lokuhlola luqukethe ikakhulukazi izingxenye ezifaka phakathi izinto zokuhlola, izinhlelo zokuhlola ze-hydraulic, izinhlelo zokuhlola ze-pneumatic, izinhlelo zokuthola amabhamuza, kanye nezinhlelo zokujikeleza izinga lokushisa. Bheka ithebula elilandelayo ukuze uthole isakhiwo sesistimu kanye nemishini eyinhloko yesistimu ngayinye.

Kuzo zonke izinhlelo ezingaphansi ezishiwo ngenhla, kudingeka ithuluzi lokuhlola elakhelwe ngenhloso ukuze kuvunyelwe ukufakwa, ukulungiswa, kanye nokuhlelwa kwamathuluzi, kuhlangatshezwane nezimo ezahlukahlukene zokuhlola, futhi kuqinisekiswe imiphumela yokuhlolwa.

Ama-adaptha epayipi abekwe kusengaphambili okuhlola ahlanganiswe ku-facturing, okuvumela ukuxhumana namapayipi okuhlola ahambisanayo ngesikhathi sokuhlola. Le facturing isekela ukuhlolwa kokucindezela okufanele (umoya/i-hydraulic) ngaphansi kwezimo zokushisa ezizungezile, eziphakeme, neziphansi.

Izidingo Zokuklama Uhlelo Lokwenza Amathuluzi

Ohlelweni lwamathuluzi, ungqimba olwengeziwe lwe-casing kufanele lufakwe ngaphandle kwe-test casing ukuze kujikelezwe ukujikeleza okuphakathi ekuhlolweni kokushisa okuphezulu nokuphansi. Lokhu kuqinisekisa izinga lokushisa lokuhlola elizinzile ngaphakathi kwe-casing futhi kuthuthukisa ukuphepha. Indlela ye-piston elinganiselayo ingaklanywa ukulawula umthwalo we-axial wethuluzi lokuhlola ngokushintshana kwe-hydraulic. Ama-valve okuphepha kufanele afakwe kuwo wonke amapayipi okuhlola ukuqinisekisa ukuphepha kwenqubo yokuhlola.

Ekuhlolweni kwegesi kanye nokuhlolwa kokutholwa kwamabhamuza, amadivayisi anjengezitholi zamabhamuza, ama-valve okusiza ukucindezela kanye nama-valve okuphepha kufanele engezwe epayipini ukuqinisekisa ukuphepha kwabasebenzi ngesikhathi sokuhlolwa. Ngesikhathi sokutholwa kwamabhamuza, iphampu ye-vacuum kufanele ingezwe epayipini ukuze kulondolozwe isimo se-vacuum, okuqinisekisa ukunemba kokutholwa kwamabhamuza.

Izinqubo Zokuhlola Ukucindezela Okuphezulu Nokushisa Okuphezulu

1.Xhuma ipayipi lokulawula, sebenzisa ingcindezi yokusetha elinganisiwe, bese usetha i-packer.

2.Xhuma i-adaptha yepayipi yokujikeleza izinga lokushisa kuphampu kawoyela oshisayo, qala ukujikeleza, bese ufinyelela izinga lokushisa lokuhlola.

3.Xhuma iphampu ye-hydraulic ku-adaptha yephayiphi ye-hydraulic/pneumatic, kancane kancane ucindezele ingcindezi yokuhlola, ubambe ingcindezi, bese uhlola ukuthi isimo sokubamba ingcindezi siyahlangabezana yini nezidingo.

4.Xhuma iphampu ye-hydraulic ku-adaptha yephayiphi ye-hydraulic/pneumatic, kancane kancane ucindezele ingcindezi yokuhlola, ubambe ingcindezi, bese uhlola ukuthi isimo sokubamba ingcindezi siyahlangabezana yini nezidingo.

5.Xhuma umthombo wegesi ku-adaptha yepayipi le-hydraulic/pneumatic nge-compressor ye-booster, kancane kancane ucindezeleke kungcindezi yokuhlola, ubambe ingcindezi, bese ubheka umphumela wokutholwa kwe-bubble detector ukuze uhlole ukuthi iyahlangabezana yini nezidingo.

Izinqubo Zokuhlola Ezinomfutho Ophakeme Nezinga Lokushisa Eliphansi

Xhuma i-adaptha yepayipi yokujikeleza izinga lokushisa ohlelweni lwegesi ebandayo, qala iphampu ukuze ijikeleze, bese ufinyelela izinga lokushisa lokuhlola; izinqubo ezisele ziyafana nalezo ezingenhla.

Izinqubo Zokufaka Isicelo Sokulayisha

Ngemva kokufinyelela ingcindezi yokuhlola elinganisiwe nokuqedela ukuzinza kwengcindezi, faka ingcindezi ezingxenyeni eziphezulu nezingezansi ze-adaptha ye-piston ukuze uyiguqule ibe yimithwalo ye-axial ngezindlela ezahlukene.

Imvilophu Yokusebenza

Ngemva kokuqeda zonke izivivinyo eziqokiwe, kukhiqizwa umbiko wokuhlola, bese kudalwe umdwebo wemvilophu yokusebenza kwe-packer ngokusekelwe emiphumeleni yokuhlolwa. Okulandelayo umdwebo wesampula we-packer etholakala kabusha ebekwe ngamanzi enesilinganiso sokucindezela esingu-7500 psi kanye nokukhishwa kwe-shear okungu-40,000-lb.
