Indlela yokukhetha i-sleeve stabilizer

I-sleeve stabilizer sisixhobo esifakwe kwi-casing string ukubeka embindini umtya we-casing kwiqula. Ineempawu zesakhiwo esilula, ukusetyenziswa kakuhle, ubomi benkonzo ende, kunye neendleko eziphantsi. Umsebenzi ophambili we-sleeve stabilizer ngu:

l Ukunciphisa i-eccentricity ye-casing, ukuphucula ukusebenza kwe-cementation displacement, ukukhusela ngokufanelekileyo i-samente slurry ukusuka kumjelo, ukuqinisekisa umgangatho we-samente, kunye nokufezekisa isiphumo esihle sokutywinwa.

l Ukuxhaswa kwe-sleeve stabilizer kwi-casing kunciphisa indawo yoqhagamshelwano phakathi kwe-casing kunye nodonga lwe-wellbore, ngaloo ndlela inciphisa amandla okukhuhla phakathi kwe-casing kunye nodonga lwe-wellbore, oluyinzuzo ukuba i-casing ihanjiswe xa ibaleka emthonjeni kwaye isamente.

l Nciphisa umngcipheko wokuncamathela kwecasing kwicasing esezantsi kwaye wehlise umngcipheko wokuncamathela kwecasing. I-sleeve stabilizer igxininise i-casing kwaye iyayinqanda ukuba ibambelele ngokuqinileyo kudonga lomthombo. Nakumacandelo equla anokungena kakuhle, i-casing ayinakwenzeka ukuba ibambeke ngamaqebengwana odaka awenziwe ngoxinzelelo loxinzelelo kwaye abangele iijam zokomba.

l I-sleeve stabilizer inokunciphisa idigri yokugoba ye-casing equleni, ngaloo ndlela inciphisa ukugqoka kwe-casing ngesixhobo sokubhoboza okanye ezinye izixhobo ze-downhole ngexesha lokugaya emva kokuba i-casing ifakwe, kwaye idlala indima ekukhuseleni i-casing.

Kukho iindidi ngeendidi zezizinzisi zemikhono, kwaye ukukhethwa kwazo kunye nokubekwa kwazo zihlala zisekwe kumava ngexesha lokusetyenziswa kwendawo, kunqongophala isishwankathelo sethiyori ecwangcisiweyo kunye nophando. Ngophuhliso olukhulayo lokugrumba ukuya kumaqula antsonkothileyo anje ngamaqula anzulu kakhulu, amaqula amakhulu okufuduswa, kunye namaqula athe tye, izizinzisi zesiqhelo zemikhono azisakwazi ukuhlangabezana neemfuno zolwakhiwo oluphantsi komhlaba. Ngoko ke, kuyimfuneko ukwenza uhlalutyo olucwangcisiweyo kunye nokuthelekisa iimpawu zesakhiwo, ukusetyenziswa, kunye nokubekwa ngokufanelekileyo kweentlobo ezahlukeneyo ze-sleeve stabilizers ukukhokela imisebenzi yokwakha kwisayithi.

Ukuhlelwa kunye neempawu ze-casing centralizers

Ngokweemeko zokwenyani zequla kunye neempawu zolwakhiwo, iinkqubo zokwenziwa, kunye nemathiriyeli yezinzisi zemikhono, izinzisi zemikhono zahlulwe zaba ziindidi ezahlukeneyo. Ngokwemigangatho yoshishino lwepetroleum, izizinzisi zemikhono zihlala zohlulwa zibe zizinzinzisi ezilastiki kunye nezizinzisi eziqinileyo.

1.1 Ukuhlelwa kunye neempawu zobugcisa be-elastic stabilizers

I-Elastic centralizer lolona hlobo lwakuqala nolona lusetyenziswa ngokubanzi lwe-centerizer. Inexabiso eliphantsi lokuvelisa, iintlobo ezahlukeneyo, kunye neempawu zokuguqulwa okukhulu kunye namandla okubuyisela. Akuqinisekisi nje kuphela ukugxilwa kwe-casing, kodwa kwakhona kunokupasa kakuhle kumacandelo equla kunye notshintsho olukhulu lobubanzi, kunciphisa ukuxhatshazwa kwe-frictional of casing insertion, kunye nokuphucula ukufana kokuqiniswa kwe-cement phakathi kwe-casing kunye ne-wellbore.

1.2 Ukuhlelwa kunye neempawu zobugcisa bezinzisi eziqinileyo

Ngokungafaniyo ne-elastic stabilizers, i-stabilizers eqinile ngokwazo ayenzi nayiphi na i-deformation e-elastic, kwaye i-diameter yabo yangaphandle yenzelwe ukuba ibe yincinci kunobukhulu be-drill bit, okukhokelela ekufakeni ukufakwa okuphantsi, okwenza ukuba zilungele ukusetyenziswa kwi-wellbore eqhelekileyo kunye ne-casing.

Ukhetho olufanelekileyo lwendlela yokudibanisa kwi-3 casing centralizers kunye nokubekwa

Iindlela ezahlukeneyo zokuzinzisa zineengenelo kunye nezingeloncedo zazo ngenxa yeyantlukwano kulwakhiwo, imathiriyeli, kunye nenkqubo yokuvelisa, kwaye zilungele iimeko zamaqula ezahlukeneyo. Uhlobo olufanayo lwe-casing centralizer, ngenxa yeendlela ezahlukeneyo zokubeka kunye nezithuba, kunokubangela iziphumo ezahlukeneyo zokubeka indawo kunye kunye nokukhuhlana kwe-casing. Ngokomzekelo, ukuba i-centralizer ifakwe ngokuqinileyo, iya kwandisa ukuqina komtya we-casing, okwenza kube nzima ukufaka i-casing kunye nokunyusa iindleko zokusebenza; Ukubekwa okungonelanga kwe-stabilizers kunokubangela uqhagamshelwano olugqithisileyo phakathi kwe-casing kunye ne-wellbore, ekhokelela ekugxininiseni okungahambi kakuhle kwe-casing kunye nokuchaphazela umgangatho we-cementing. Ke ngoko, ngokweentlobo ezahlukeneyo zequla kunye neemeko, ukukhetha isizinzi semikhono esifanelekileyo kunye nokudityaniswa kokubeka kubalulekile ekunciphiseni ukungqubana kwecasing kunye nokuphucula ukugcinwa kwecasing centering.
