Iindidi zeePlagi zeBridge

Iiplagi zebhulorho zizixhobo zomngxuma osezantsi ezimiselwe ukwahlula indawo esezantsi yequla. Iiplagi zebhulorho zisenokuba zisisigxina okanye zifumaneke, nto leyo eyenza ukuba umthombo osezantsi uvalwe ngokusisigxina kwimveliso okanye ubekelwe bucala okwethutyana kunyango oluqhutywa kwindawo ephezulu. Ziqulunqwe ngeziliphu, mandrel, kunye elastomers (iziqalelo zokutywina).
Iindidi zeeplagi zebhulorho
Njengoko kukhankanyiwe ngasentla, iiplagi zebhulorho zinokuba;
Iiplagi zeBridge ezifumanekayo (RBP) okanye iiPlugs zeThutyana zeBridge.
Iiplagi zeBhulorho ezisisigxina (PBP) okanye iMillable/Drill-Through Bridge Plugs.
Iiplagi zeBridge ezifumanekayo (RBP)
Ezi ziiplagi zoxinzelelo oluphezulu zemultizone kunye nemisebenzi ekhethiweyo yezowuni enye efana ne-acidizing, fracturing, cementing, kunye novavanyo. I-RBPs inokumiselwa kwi-tension okanye i-compression. Zisenokuthi zibekwe nzulu kwi-casing engaxhaswanga ukuba ziqulathe uxinzelelo ngelixa zisebenza kwisixhobo se-wellhead.
Ii-RBPs zinokusetwa kuxinzelelo olwenza ukuba lulungele ukuseta izixhobo ezinzulu zokuvavanya iintloko zequla kwaye zinzulu ukuvavanya amaqula anoxinzelelo oluphezulu. Ibonisa i-by-pass enkulu yangaphakathi ukunciphisa i-swabbing xa uqhuba kwaye ubuyisela. I-by-pass ivala ngexesha lokumisela iiplagi kwaye ivule ngaphambi kokukhulula iziliphu eziphezulu ukulinganisa uxinzelelo xa ungacwangciswanga. I-by-pass ifumaneka ngokuthe ngqo ngaphantsi kweziliphu eziphezulu ukunceda ukuhlamba inkunkuma xa i-by-pass ivuliwe. Iiplagi zebhulorho ezibuyisekayo zinokusetyenziselwa imisebenzi yokulahla okwexeshana okanye ngokuhambelana nezipakisho zenkonzo ezifumanekayo ukuze zisebenze.
Iiplagi zeBhulorho ezisisigxina (PBP) okanye iMillable/Drill-Through Bridge Plugs
Ezi ziiplagi zebhulorho eziyilelwe/ziphuhliselwe ukuvala okanye ukwahlula inxalenye yequla ngokusisigxina. Zidla ngokuyilwa ngeentsimbi ezinyibilikayo kungoko zikwabizwa ngokuba yi-drill through okanye iiplagi zebhulorho ezigugiswayo ezisisigxina.
Iiplagi zebhulorho ezisisigxina zifanelekile kwiikhemikhali eziguquguqukayo okanye iindawo zegesi ezimuncu. I-PBP inokumelana noxinzelelo olusuka kwi-10,000psi ukuya kwi-15,000psi kunye nokushisa okuphezulu kwe-327 ° C (638 ° F) kunye nokushisa okuqhelekileyo kwe-205 ° C (400 ° F).
IiPlagi zeBhulorho zokutywina izinto (iiElastomers eziNcumbayo)
Iiplagi zebhulorho zinento ekhubazekayo esetyenziselwa ukwenza itywina kudonga lwequla elijikelezileyo. Xa isetyenziswa, isiqalelo esonakeleyo sinokufuna ukudlula kumda omncinci kunobubanzi bomngxuma wokutsala apho ielementi iza kusekwa khona. Ngenxa yoko, ubungakanani bento ekhubazekileyo inokuthintelwa ngowona mda umncinci wedayamitha eya kuthi isetyenziswe ngawo. Nje ukuba ibekwe kwindawo efunwayo, into enokonakala inokusetwa ngokucinezelwa, ukunyuka kwamaxabiso, okanye ukudumba kuxhomekeke kuhlobo lwento esetyenzisiweyo. Izinto ezidumbayo zithatha ixesha elininzi (umzekelo, iintsuku ezininzi) ukudumba xa kukho into esebenzayo, kwaye izinto ezidumbileyo zikholisa ukongamela ixesha elongezelelweyo. Xa i-inflatable element isetyenzisiweyo, ibeka kwindawo edilikayo kwaye emva koko ivuthe xa ibekwe ngokufanelekileyo. Ngelishwa, i-elementi enokuvutheka inokonakala, kunokuba nzima ukuyiphumeza, kwaye inokuchatshazelwa lutshintsho kumaqondo obushushu asezantsi.
Ngendlela eqhelekileyo, iiplagi zisebenzisa i-compression set element ene-sleeve ecinezelweyo ukwandisa i-diameter ye-element ukwenza itywina. Ukucinezela izinto ezinjalo kunokufuna amandla amaninzi kunye ne-stroke ende.
Izinto zokutywina ezifakwe kwiiplagi zeBridge zixhomekeke kwiipropati zequla, uhlobo lomthombo wequla, ubushushu kunye noxinzelelo lwequla.
Indlela yoHambo
Iiplagi zebhulorho zinokufakwa kubunzulu obujoliswe kubo equleni kusetyenziswa iindlela ezahlukeneyo zokuhambisa. Indlela yokuhambisa ixhomekeke kwezinye izinto ezifana neprofayili (indlela yokuthutha), ubunzulu bequla, kwaye okona kubaluleke kakhulu kwiindleko zokuhambisa.

Usetyenziso lweePlagi zeBridge
Iiplagi zebhulorho zidla ngokusetyenziselwa ukwahlukaniswa kwendawo kwiindawo ezahlukeneyo zequla. Iplagi yebhulorho isenokwenziwa ukuze kuqhutywe umsebenzi okanye imisebenzi yongenelelo kwicandelo elithile lomthombo. Ukuseta iplagi yebhulorho kwindawo inceda ukufezekisa ukwahlukaniswa kweendawo ezininzi ukwenza imisebenzi ngokufanelekileyo kwindawo eyahlukileyo yequla ngaphandle kokuchaphazela ezinye iindawo.
Iiplagi zebhulorho nazo zisetyenziselwa ukuplaga kunye nemisebenzi yokulahla. Xa isixa sehydrocarbon kwidama singasathengiswa okanye umthamo wedama ukhutshiwe ngemveliso, imfuneko yokulahlwa kwequla iyavela. Umyili wequla usenokukhetha ukuseta iiplagi zebhulorho edityaniswe nodaka lwesamente ukuqinisekisa ukuba isamente yoxinaniso oluphezulu ayiweli kumthombo. Kuloo meko, iplagi yebhulorho izakusetwa kwaye isamente impompelwe phezu kweplagi ngombhobho wokubhobhoza, kwaye ke umbhobho wokubhobhoza utsalwe phambi kokuba udaka lujiye.
Amandla anokubonelela ngeeplagi zebhulorho ezisisigxina ezintathu ezahlukeneyo, ezibandakanya iiplagi zebhulorho ezinyibilikayo, iiplagi zebhulorho ezidibeneyo kunye neeplagi zebhulorho zentsimbi, iiplagi zebhulorho ezisisigxina zeVigor ziye zasetyenziswa kwiindawo ezinkulu ze-oyile ekhaya nakwamanye amazwe kwaye ziye zamkelwa kakhulu ngabathengi. Ukongeza, iplagi yebhulorho enokuphinda isetyenziswe yeVigor ikwayenye yezona mveliso zidumileyo, ezaziwa ngolawulo lwayo olungqongqo lomgangatho kunye nokusebenza okugqwesileyo, kwaye iba yenye yokhetho lokuqala lwezixhobo zokugqibezela abathengi abaninzi. Ukuba unomdla kwi-Vigor Completion Tool Bridge Plug Series okanye ezinye izixhobo zokugaya kunye nokugqiba kwishishini leoli kunye negesi, nceda unganqikazi ukuqhagamshelana nathi ngenkxaso yemveliso engcono kunye nenkxaso yobugcisa.
