Sleeve stabilizer ke sesebelisoa se kentsoeng khoeleng ea casing ho theha khoele ea casing ka har'a seliba. E na le litšobotsi tsa sebopeho se bonolo, tšebeliso e bonolo, bophelo bo bolelele ba ts'ebeletso, le litšenyehelo tse tlase. Mosebetsi o ka sehloohong oa stabilizer ea sleeve ke:
l Fokotsa ho nepahala ha casing, ho ntlafatsa ts'ebetso ea ho falla ha samente, ho thibela ka nepo seretse sa samente ho tloha mocheng, ho netefatsa boleng ba samente, le ho fihlela phello e ntle ea ho tiisa.
l Tšehetso ea "sleeve stabilizer" holim'a casing e fokotsa sebaka sa ho kopana pakeng tsa casing le lerako la seliba, ka hona ho fokotsa matla a khohlano pakeng tsa casing le lebota la seliba, e leng molemo bakeng sa hore casing e sisinyehe ha e matha ka selibeng. ho tiisa.
l Fokotsa kotsi ea ho khomarela khese karolong e ka tlaase le ho fokotsa kotsi ea ho khomarela khese. Sleeve stabilizer e beha sebaka sa polokelo 'me e se thibela ho khomarela leboteng la seliba. Esita le likarolong tsa seliba tse nang le ho phunyeletsa hantle, casing ha e na monyetla oa ho ts'oaroa ke mahobe a seretse a entsoeng ke likhatello tse fapaneng le ho baka jeme ea ho cheka.
l Sleeve stabilizer e ka fokotsa tekanyo ea ho khumama ea casing ka selibeng, kahoo e fokotsa ho roala ha casing ka sesebelisoa sa ho phunya kapa lisebelisoa tse ling tsa ho phunya nakong ea ts'ebetso ea ho cheka ka mor'a hore casing e kenngoe, le ho bapala karolo ea ho sireletsa casing.
Ho na le mefuta e fapaneng ea li-sleeve stabilizers, 'me khetho ea tsona le ho beoa hangata li ipapisitse le boiphihlelo nakong ea ts'ebeliso ea sebaka sa marang-rang, e haelloang ke kakaretso e hlophisitsoeng ea theory le lipatlisiso. Ka nts'etsopele e ntseng e eketseha ea ho cheka liliba tse tebileng joalo ka liliba tse tebileng haholo, liliba tse kholo tsa phalliso, le liliba tse tšekaletseng, li-stabilizer tse tloaelehileng ha li sa khona ho fihlela litlhoko tsa kaho ea ka tlas'a lefatše. Ka hona, hoa hlokahala ho etsa tlhahlobo e hlophisitsoeng le ho bapisa litšobotsi tsa sebopeho, ho sebetsa, le ho beoa ka nepo ha mefuta e fapaneng ea li-sleeve stabilizers ho tataisa ts'ebetso ea kaho setšeng.
Classification le litšobotsi tsa casing centralizers
Ho ea ka maemo a 'nete a seliba le litšobotsi tsa sebopeho, lits'ebetso tsa tlhahiso, le lisebelisoa tsa li-sleeve stabilizers, li-sleeve stabilizer li arotsoe ka mefuta e fapaneng. Ho ea ka maemo a indasteri ea peterole, li-sleeve stabilizers hangata li arotsoe ka li-stabilizer tse elastic le li-stabilizer tse thata.
1.1 Likarolo le litšobotsi tsa tekheniki tsa li-elastic stabilizers
Elastic centralizer ke mofuta oa pele le o sebelisoang haholo oa centralizer. E na le litšenyehelo tse tlase tsa tlhahiso, mefuta e fapaneng, le litšoaneleho tsa deformation e kholo le matla a ho hlaphoheloa. Ha e netefatse feela setsi sa casing, empa hape e na le ho feta hantle bakeng sa likarolo tsa seliba tse nang le liphetoho tse kholo tsa bophara, ho fokotsa khanyetso ea likhohlano tsa ho kenngoa ha casing, le ho ntlafatsa ho tšoana ha ho kopanya samente pakeng tsa casing le seliba.
1.2 Litšobotsi le litšobotsi tsa tekheniki tsa li-stabilizer tse thata
Ho fapana le li-elastic stabilizers, li-stabilizers tse thata ka botsona ha li kenye letsoho, 'me bophara ba tsona bo ka ntle bo etselitsoe ho ba nyane ho feta boholo ba mochini oa ho phunya, e leng se etsang hore ho be le likhohlano tse tlase tse kentsoeng, tse etsang hore li tšoanelehe bakeng sa ho sebelisoa ka har'a wellbore le casing.
Khetho e nepahetseng ea mokhoa oa ho kopanya bakeng sa 3 casing centralizers le ho beoa
Li-sleeve stabilizers tse fapaneng li na le melemo le mathata a tsona ka lebaka la phapang ea sebopeho, thepa le ts'ebetso ea tlhahiso, 'me li loketse maemo a fapaneng a liliba. Mofuta o ts'oanang oa casing centralizer, ka lebaka la mekhoa e fapaneng ea ho beoa le sebaka, o ka baka litlamorao tse fapaneng tsa bohareng le khohlano ea casing. Ka mohlala, haeba centralizer e behiloe ka thata haholo, e tla eketsa ho tiea ha khoele ea casing, ho etsa hore ho be thata ho kenya casing le ho eketsa litšenyehelo tsa ts'ebetso; Ho se behoe ho lekaneng ha li-stabilizers ho ka etsa hore ho be le puisano e feteletseng pakeng tsa casing le seliba, e leng se lebisang tlhokomelong e mpe ea casing le ho ama boleng ba samente. Ka hona, ho ea ka mefuta le maemo a fapaneng a liliba, ho bohlokoa ho khetha "stabilizer" e nepahetseng le motsoako oa ho beoa ho bohlokoa bakeng sa ho fokotsa likhohlano tsa casing le ho ntlafatsa casing centering.
