I-Packer Setting Mechanisms

I-Weight-Set noma I-Compression Set Packers

Lolu hlobo lwe-packer lungasethwa ngokuzimela noma lungaqhutshwa njengengxenye ebalulekile yeyunithi yezinhlamvu zeshubhu futhi lusethwe lapho intambo imiswa.

Ngokuvamile abapakishi besethi yesisindo basebenzisa isiliphu kanye nokuhlanganiswa kwekhoni okungase kucushwe ukuze kunikeze ukucindezelwa kwesici sophawu, uma iziphethu zokudonsa noma amabhlogo okushayisana akwazi ukubandakanya udonga lwangaphakathi lwekheshi. Izindlela zokukhulula iziliphu zivame ukutholwa kusetshenziswa isisetshenziswa se-J slot okuthi lapho sisebenza sivumele isisindo sentambo ukuba sehliswe bese kucindezela into yokuvala. Ukukhishwa kwesici kungatholakala ngokuthatha isisindo sentambo.

Lolu hlobo lwenqubo yokumisa i-packer luzofaneleka kuphela uma isisindo singasetshenziswa kumpakishi okungenzeka kungabi njalo emithonjeni ethambekele kakhulu. Ngaphezu kwalokho, umpakishi uzokhumula uma umehluko wengcindezi ephezulu ukhona kusuka ngaphansi kompakishi.

Amapaki asethi yokuminyanisa ngokuvamile adinga amandla amancane okusetha amaphawundi angu-8,000 kuya ku-14,000 ezintweni (i-packer element durometer kanye nezinga lokushisa ekujuleni kokusetha nakho kufanele kucatshangelwe). Lokhu kungaba yinkinga ngaphansi kwamamitha angu-2,000 njengoba isisindo sepayipi lokubhoboza esidingekayo siyangabazeka kuye ngosayizi wompakishi kanye nosayizi weshubhu/isisindo ngonyawo ngalunye.

Lolu hlobo lwesipakishi luyiphakethe lesethi yesisindo eligijima libheke phansi, okungukuthi isistimu yokushelela neyekhoni itholakala ngaphezu kwesici sokuvala. Ziwusizo ikakhulukazi ezinhlelweni zokusebenza lapho ukucindezela kwembobo ephansi ephezulu ngakho-ke kukhona ingcindezi ehlukile esuka ngaphansi kompakishi. Lesi simo senzeka emithonjeni yokujova amanzi, lapho ingcindezi yomjovo izosiza ekugcineni isilungiselelo sepaki. Kufanele kuqashelwe ukuze kuqinisekiswe ukuthi noma yikuphi ukukhuphuka kwezinga lokushisa kuyunithi yezinhlamvu kanye nokwandiswa kweyunithi yezinhlamvu ezilandelanayo ngeke kunikeze amandla angakwazi ukukhulula ipakethi.

Inketho evame kakhulu yokuphothula isethi engajulile yipaki yesethi yomshini- tension-set. Lokhu mhlawumbe kungenxa yokuthi umthombo ongashoni ngokuvamile ubonisa izimo zomnotho ezingatheni futhi umshini wokusetha ukucindezeleka uvamise ukubiza kancane kunesethi ye-hydraulic noma isethi yocingo oluhambisanayo olubuyiselekayo.

I-Roto-Mechanical Set Packers

Kulolu hlobo lwepaki, inqubo yokumisa ipaki iculwa ngokuzungezisa amashubhu. Ukuzungezisa kwentambo noma

iphoqa ama-cones ukuthi ashelele ngemuva kwesiliphu futhi ngaleyo ndlela acindezele uphawu, noma akhulule i-mandrel yangaphakathi ukuze isisindo seshubhu sisebenze phezu kwama-cones ukucindezela isici sokuvala.

Amaphakethe we-Hydraulic-Set

Kulolu hlobo lwesipakishi, inqubo yokusetha incike ekucindezelweni kwe-hydraulic okukhiqizwa ngaphakathi kwentambo esetshenziselwa noma:

●shayela ipiston ukwenza ukunyakaza kwesistimu yokushelela kanye nekhoni ngaleyo ndlela ihlanganise isici sophawu, noma okunye

●sebenzisa isethi yeziliphu eziphezulu kumpakishi ezizobe sezilungisa indawo yompakishi futhi zivumele ukungezwani ukuthi kudonswe kumpakishi bese kucindezela uhlelo lokuvala.

Ohlelweni lwangaphambili, uma i-piston eshayelwa ngamanzi isebenze ukunyakaza kwekhoni, ukunyakaza kokubuya kwekhoni kufanele kuvinjwe idivayisi yokukhiya engumshini.

Ukuvumela umfutho we-hydraulic ukuthi ukhiqizwe kushubhu ngaphambi kokumiswa kwesipakishi, izinqubo ezi-3 eziyinhloko ziyatholakala zokuxhuma ishubhu:

●Ukufakwa kwepulaki engenalutho njengepulaki ye-Baker BFC ngaphakathi kwengono efanelekile njengengono ehlala i-Baker BFC.

●Ukusetshenziswa kwesihlalo esisebenziseka kalula lapho ibhola lingehliselwa kuso intambo yeshubhu. Lapho usebenzisa ingcindezi eyeqile ngemva kokusetha umpakishi, ibhola nesihlalo kuyaphuca bese kuwela ku-sump yomthombo. Enye idizayini ifaka ikholethi enwebekayo ezokwehla futhi inwebe idlule lapho ingcindezi isisike amaphini, ngaleyo ndlela ivumele ibhola ukuthi lidlule.

●Ukusetshenziswa kwe-sub ehlukanisayo yokukhipha, kuvumela uketshezi lweshubhu ukuthi lususwe ngokusebenzisa izimbobo ku-sub ngaphambi kokusetha ipakeli. Ibhola uma liwisiwe lizohlala phezu kwekholethi enwebekayo okuzovumela ukuthi kukhiqizwe ingcindezi. Uma i-overpressure isetshenzisiwe i-collet iya phansi futhi ngokwenza kanjalo, ivala i-valve yokujikeleza futhi ivumele ibhola ukuthi liwele phakathi.

Amaphakethe wezilungiselelo zezintambo zikagesi

Kulolu hlelo, ikhithi ye-adaptha ekhethekile ixhunywe kumpakishi, ngopayipi noma ngaphandle kwawo, futhi isistimu ifakwa emthonjeni ocingweni ngensimbi yokuxhumana ejulile njenge-casing collar locator CCL Ekujuleni kokusetha, ugesi kagesi. isignali edluliselwe phansi ikhebula ithungela ishaja yokuqhuma evutha kancane etholakala ethuluzini lokusetha elikhulisa kancane kancane umfutho wegesi futhi lishukumise ukunyakaza kwepiston ukuze iminyanise isistimu yokuvala uphawu.

Lolu hlobo lwesistimu luholela encazelweni enembe kakhudlwana yokujula kwesilungiselelo yesipakishi kanye nenqubo yokusetha/yokufaka eshesha kakhulu. Ububi buwubunzima bokusebenzisa izintambo emithonjeni ene-engeli ephezulu kanye neqiniso lokuthi umpakishi kufanele abekwe ngokwehlukana nokufakwa okulandelayo kweshubhu.

Imikhiqizo yokupakisha ye-Vigor ikhiqizwa futhi yenziwe ngokuhambisana namazinga e-API 11 D1, okwamanje singakunikeza izinhlobo ezi-6 ezihlukene zamapaki, okwamanje, amakhasimende alondoloze ukuhlolwa okuphezulu kakhulu kwemikhiqizo yethu yokupakisha, amanye amakhasimende abeke phambili izidingo ezenziwe ngokwezifiso, Onjiniyela bezobuchwepheshe be-Vigor nonjiniyela bokuthenga bafuna izixazululo ezinokwethenjelwa kakhulu zamakhasimende ethu. Uma unentshisekelo ngemikhiqizo yokupakisha ye-Vigor, imishini yokumba nokuqedela ukugawulwa kwemithi, noma izinsizakalo ezenziwe ngokwezifiso ze-OEM, sicela ungangabazi ukusithinta ukuze uthole ukwesekwa kobuchwepheshe obuchwepheshile.
