Izinto eziDityanisiweyo ezisetyenziswa kwiplagi yeBhulorho eDityanisiweyo kunye nePlug yeFrac

Inkcazo ye-composite yinto eyenziwe ngezinto ezingaphezulu kwesinye. Ngeenjongo zethu, i-composite ibhekisa kwi-fiberglass. Zonke iiplagi ezidibeneyo zenziwe ngokuyintloko ngezinto zefiberglass, ezidityaniswe neefiber zeglasi kunye ne-resin material. Iifiber zeglasi zincinci kakhulu, amaxesha angama-2-10 amancinci kuneenwele zomntu, kwaye ziyaqhubeka kwaye zilimaza / ziboshwe kwi-resin okanye zinqunyulwe kwaye zibunjwe kwi-resin. Izinto ze-resin zibophelela iglasi kunye, ivumela ukuba imile. Ngokusisiseko, iifiber zeglasi kunye neresin ziyadityaniswa emva koko zinyangeke zibe yinto eqinileyo. Ukusuka apho, okuqinileyo kwenziwa ngoomatshini bemilo enokusetyenziswa. Kukho iindlela ezininzi zokudibanisa i-resin kunye neglasi ukufezekisa injongo oyifunayo. Ezinye zeendlela zokuvelisa ezidityanisiweyo ezisetyenzisiweyo ekwakhiweni kweeplagi ezidityanisiweyo linxeba le-filament, i-convolute wrap, kunye ne-resin transfer composite. Ngalunye lolu hlobo ludibanisa i-resin kunye neglasi kwiindlela zokufezekisa iipropati ezahlukeneyo.

Inxeba leFilament

Ngomxube wenxeba le-filament, imicu yeglasi eqhubekayo itsalwa ngentlaka engamanzi ukuze igqunywe. Iintsinga ke zisondezwe malunga mandrel yentsimbi ukwenza ityhubhu edityanisiweyo. Emva kokuba i-diameter efunwayo yangaphandle (OD) ye-composite ifezekisiwe, ityhubhu edibeneyo & i-mandrel yesinyithi iyasuswa kumatshini wokujija kwaye iphiliswe ngaphakathi kwe-oven ukwenza i-composite eqinileyo. Emva kokunyanga, i-metal mandrel iyasuswa kwaye ityhubhu eseleyo edibeneyo ingatshintshwa ibe ngamacandelo ahlukeneyo.

I-Filament inxeba edibeneyo ilungile kakhulu kumacandelo e-tubular. Zinokwenziwa ngobunjineli obuphezulu ngeendidi ezithile zeglasi, iintlobo zeresin, kunye nepateni yomoya yeentsinga zeglasi. Ezi ziguquko zingatshintshwa ukufezekisa iinjongo ezahlukeneyo ezibandakanya ukuwa okuphezulu, ukuphakama okuphezulu, ukulinganisa ubushushu obuphezulu, ukugawula lula, njl. Konke oku kuxhamla ukuveliswa kweeplagi zefrac ezidibeneyo kuba sisebenza ngaphakathi kwityhubhu kwaye kufuneka sibeke ngaphakathi kwityhubhu. (ibhokisi).

Kwakhona, oomatshini bokujija imisonto banokuvuthela ukuya kuthi ga kwiityhubhu ezingama-30 zokudityaniswa, ezinye zazo ezinokuvuthela ezi-6 zale mibhobho ngexesha. Kulula ukuvelisa imiqulu yenxeba lemicu edityaniswe nenani eliphantsi lomsebenzi. Oku kuziboleka ekuveliseni umthamo wemveliso ngexabiso eliphantsi.

Convolute

Ngelixa oomatshini bokulimala be-filament basebenzisa imicu yeglasi emide eqhubekayo ukusonga i-resin efakwe iglasi kwiityhubhu, i-convolute composite yenziwa kusetyenziswa ilaphu elilukiweyo leglasi esele lifakwe intlaka. Le ilaphu "pre-preg" ijikelezwe malunga mandrel ukwenza ityhubhu, kwaye ke unyange ukuba lukhuni ibe composite. Inzuzo yokusebenzisa indwangu eyenziwe ngeglasi, kunokuba imicu eqhubekayo, kukuba ufumana amandla eglasi kwiindlela ezimbini. Oku kongeza amandla ongezelelweyo kwi-composite ye-tensile kunye ne-compressive applications.

Ukudluliselwa kweResin

Ngokubunjwa kodluliselo, ilaphu leglasi libotshelelwe okanye lenziwe ngaphakathi kokungunda kwimo ethile. Ilaphu ke lifakwe kwi-resin ngokusebenzisa inkqubo yokudlulisa. I-resin ibanjwe kwiqondo lokushisa elithile kwisitya kwaye ilaphu leglasi ligcinwe ngaphakathi kwevacuum. I-resin ke ikhutshwe kwindawo yokucoca yeglasi, inyanzelisa i-resin kwi-voids phakathi kwemicu yeglasi ngaphakathi kwelaphu. Umdibaniso uyaphiliswa kwaye umatshini wokwenza inxalenye yokugqibela.

Ukubunjwa okubunjiweyo

Imixube exonxiweyo zisebenzisa iBulk Molding Compounds (BMC) ukwenza iimilo ezidityanisiweyo zisebenzisa naliti okanye ukubunjwa koxinzelelo. I-BMC lilaphu leglasi okanye iintsinga ezinqunqiweyo ezixutywe nentlaka. Ezi khompawundi mhlawumbi ibekwe okanye isitofu ngundo kwaye emva koko thermoset okanye unyange phantsi lobushushu kunye noxinzelelo. Inzuzo yokudibanisa okubunjiweyo kukukwazi ukuvelisa ngokukhawuleza imilo enzima kwimiqulu.

Kukho iindlela ezininzi zokudibanisa i-resin kunye neglasi kwaye ezi zimbalwa zeendlela ezisetyenziselwa ukuveliswa kweeplagi ze-frac ezidibeneyo. Eyona nto ibalulekileyo kukuba i-composite ilula ngokulula ibe ngamaqhekeza amancinci. Kwakhona, ukudibanisa kweglasi kunye ne-resin kubangela ubunzima obuthile be-1.8-1.9 ekudaleni iziqwenga eziphakanyiswa ngokulula equleni ngexesha lokugaya.

Izinto zokutyibilika

Xa ubeka iplagi edibeneyo isixhobo sigxininiswe emthonjeni kunye neeseti ze "slips". Ngokusisiseko, kukho ikhowuni edityaniswe ne-wedge. I-wedge iya kuba neendawo ezibukhali eziqinileyo ezinokuthi xa zinyanzeliswa i-cone iya "kuluma" kwi-casing, idale i-anchor ekwazi ukuvala iplagi kwindawo kunye nokumelana nemikhosi engaphezu kwe-200,000 lbs. Ukuze isiliphu "silume" kwindawo eqinile okanye imathiriyeli kufuneka ibenzima kune-casing ngokwayo, eyi-~30 HRC.

Ukutyibilika koMzimba oDityanisiweyo kunye noFakelo

Olwesibini uqwalaselo olusetyenziswa kakhulu lwesiliphu ngumzimba odibeneyo kunye namaqhosha aqiniweyo ukubonelela nge-anchoring.

Amaqhosha esinyithi

Ezinye iiplagi zinamaqhosha enziwe ngentsimbi, nokuba yintsimbi ephoswe ngokupheleleyo okanye isinyithi esingumgubo. Amaqhosha esinyithi enziwe ngomgubo enziwe kwi-sintering metallic powder kwimilo efunekayo kwiqhosha. Ngelixa isinyithi esingumgubo sivakala ngathi kuya kuba lula ukusila/ukusila konke kuxhomekeke kumgubo wesinyithi, unyango lobushushu, kunye nenkqubo yokuvelisa.

Amaqhosha eCeramic

Ezinye iiplagi ezidityanisiweyo zisebenzisa isiliphu esihlanganisiweyo esinamaqhosha e-ceramic ukubonelela ngokuluma kwi-casing. Ngelixa imathiriyeli ye-ceramic inzima kakhulu, ibuye ibe brittle kakhulu. Oku kuvumela amaqhosha e-ceramic ukuba aphuke ngcono ngexesha lokusila xa kuthelekiswa neqhosha lentsimbi. I-Ceramic ine-SG phakathi kwe-5-6, ibenza kube lula ukususa ngexesha lokusila ukuba abalingane babo besinyithi.

Slip Millability

Ugxininiso oluninzi lubekwe kumaxesha okusila kwiplagi edibeneyo kangangokuba eyona njongo yokugaya iiplagi inokulibaleka ngamanye amaxesha. Eyona njongo iphambili yokusila kukukhupha iiplagi emthonjeni. Ewe, kubalulekile ukuyenza ngokukhawuleza kwaye amaqhekeza abe mancinci. Nangona kunjalo, ukuba ukrazula iplagi ngokukhawuleza kwaye ufumane ukusika okuncinci, kodwa awususi inkunkuma equleni injongo ayikafezekiswa. Ukukhetha iplagi ene-metallic slips okanye amaqhosha kuya kwenza kube nzima ukususa yonke inkunkuma kwiiplagi nje ngenxa yobunzima obuthile bezinto.
