Umgomo wokusebenza we-sleeve stabilizer

Ebunjiniyela bokumba uwoyela, i-casing stabilizer iyithuluzi elibalulekile le-downhole, umsebenzi walo oyinhloko ukuqinisekisa indawo efanele ye-casing emgodini womthombo, ukuvimbela ukuthintana phakathi kwe-casing nodonga lomthombo, futhi unciphise ingozi yokuguga nokujamza. I-casing stabilizer idlala indima ebalulekile ekuthuthukiseni ukusebenza kahle kokumba kanye nokuvikela ubuqotho be-casing ngomklamo wayo oyingqayizivele kanye nomgomo wokusebenza.

1. Isakhiwo se-sleeve stabilizer

I-sleeve stabilizer ngokuvamile yenziwe ngensimbi enamandla kakhulu futhi inezici zokuqina nokuqina. Isakhiwo sawo ngokuvamile sihlanganisa umzimba wokuzinzisa, amapuleti asentwasahlobo, kanye nezingxenye zokuxhuma. Umzimba we-stabilizer uyingxenye eyinhloko ye-stabilizer, enamandla athile nokuqina futhi ingakwazi ukumelana nokuhlolwa kwezindawo eziyinkimbinkimbi ezingaphansi komhlaba. Amapuleti asentwasahlobo adlala indima yokusekela nokubeka indawo, futhi asatshalaliswa ngokulinganayo emzimbeni ophakathi nendawo, ajwayelane nemikhono yamadayamitha ahlukene ngokusebenzisa ukubola okunwebekayo. Ingxenye yokuxhuma isetshenziselwa ukuxhuma i-stabilizer ku-casing, ukuqinisekisa ukuthi i-stabilizer inganciphisa emgodini kanye ne-casing ngesikhathi sokumba.

2, Isimiso sokusebenza se-sleeve centralizer

Isimiso sokusebenza se-sleeve stabilizer sisekelwe ikakhulukazi ezimisweni zemishini kanye nezici zemvelo ye-downhole. Lapho i-casing ifakwe emthonjeni, ngenxa yokungahambi kahle komthombo kanye yinkimbinkimbi yokubunjwa, umkhono ungase uhlangane nodonga lomthombo, okubangela izinkinga ezifana nokugqoka nokugxuma. Ukuze ugweme lezi zinkinga, kuyadingeka ukufaka i-stabilizer ku-casing.

I-stabilizer ivumelana noshintsho lobubanzi be-casing ngokusebenzisa ukuguqulwa okunwebeka kwepuleti layo lasentwasahlobo futhi isekela umkhono endaweni emaphakathi yomthombo. Phakathi nenqubo yokumba, njengoba i-casing yehliswa ngokuqhubekayo, i-stabilizer nayo ihamba ngokufanele. Lapho umkhono uhlangana nokuncipha komthombo noma izinguquko zokwakheka, ipuleti lasentwasahlobo lesiqinisi lizocindezelwa ukuze livumelane nezinguquko zobubanzi bomkhono, kuyilapho likhiqiza amandla okusekela ahlehlayo ukuze asunduze umkhono uye phakathi nendawo yomthombo futhi alondoloze ukuzinza kwawo.

3. Isicelo kanye nezinzuzo ze-sleeve centralizers

I-sleeve stabilizer isetshenziswa kabanzi ku-petroleum drilling engineering, ikakhulukazi efanelekile ukwakheka okuyinkimbinkimbi kanye

Ukumba umthombo ojulile. Ngokusebenzisa i-stabilizer, ubungozi bokugqoka imikhono kanye ne-jamming ingancishiswa ngempumelelo, ukusebenza kahle kokumba kungathuthukiswa, nezindleko zokumba zingancishiswa. Ngesikhathi esifanayo, i-stabilizer ingaphinde ivikele ubuqotho be-casing, yandise impilo yesevisi yomkhono, futhi inikeze ukusekela okuqinile kokukhipha amafutha negesi okulandelayo.

Izinzuzo ze-sleeve centralizer ziboniswa ngokuyinhloko kulezi zici ezilandelayo: okokuqala, inezici zesakhiwo esilula nokufakwa kalula, okungakwazi ukuzivumelanisa nobubanzi obuhlukene kanye nezinhlobo zemikhono. Okwesibili, i-centralizer ine-elasticity enhle nokumelana nokugqoka, okungakwazi ukuzivumelanisa nokuhlolwa kwezindawo eziyinkimbinkimbi ezingaphansi komhlaba; Okokugcina, isizinzisi singakwazi ukuthuthukisa ukusebenza kahle kokumba futhi sivikele ubuqotho be-casing, sinikeze ukusekelwa okuqinile kokuphepha, ukusebenza kahle, nokuvikelwa kwemvelo konjiniyela bokumba i-petroleum.
