Nyob rau hauv hydraulic fracturing, lub frac plug cais tawm txhua theem yog li kev kho cov kua dej tuaj yeem tso rau hauv lub hom phiaj lub sijhawm ntawm lub siab. Nyob rau hauv lub siab -siab, siab- kub (HPHT) zoo, tib lub ntsaws yuav tsum tuav lub siab sib txawv load thaum downhole ib puag ncig tawm tsam nws lub cev, ntsaws ruaj ruaj thiab teeb tsa mechanism. Xaiv qhov tsis ncaj ncees lawm txhais tau tias qhov chaw ua tsis tiav ntxov, cov yeeb nkab daig, lossis kev xyaum ua haujlwm ntev thiab kim heev - tawm.HPHT feem ntau txhais tau tias yog qhov mob hauv qab qhov siab tshaj li ntawm 15,000 psi lossis 300℃F (149 degree) - thiab nyob rau hauv cov bass xav tau tshaj plaws, ob qho tib si txwv tau raug thawb zoo tshaj qhov ntawd.
Phau ntawv qhia no muab cov engineers ua tiav thiab pab pawg muab khoom siv rau kev xaiv frac plugs nyob rau hauv HPHT tej yam kev mob - npog hom plug, cov ntaub ntawv uas muaj sia nyob, thiab cov neeg muag khoom kuaj xyuas uas cais ib qho kev xa khoom zoo los ntawm qhov teeb meem.
Dab tsi yog Frac Plug thiab Vim Li Cas HPHT Hloov Cov Cai
Lub frac plug (feem ntau yog ib hom kev txuas txuas) yog ib qho khoom siv downhole khiav ntawm cov kab hlau los yog coiled tubing uas thauj tog rau nkoj mus rau hauv lub casing, kaw lub annulus, thiab tuav lub siab thaum cov kua dej tawg yog pumped saum nws. Tom qab theem, lub ntsaws yog tho tawm los yog, nyob rau hauv cov ntaub ntawv ntawm dissolvable designs, sab laug kom yaj nyob rau hauv lub qhov dej dej.
HPHT qhov dej hloov qhov kev xaiv logic nyob rau hauv peb txoj kev:
- Thermal txwv:Composites thiab elastomers soften los yog degrade thaum kub nce, txo cov foob thiab shear kev ncaj ncees.
- Siab load:ntau dua qhov sib txawv xav tau kom muaj zog plam kev sib koom tes thiab mandrel metallurgy.
- Dej aggression:kub, acidic los yog siab -salinity brines ua kom corrosion thiab tuaj yeem hloov tus cwj pwm sib cais.
Peb Lub Ntsiab Frac Plug Hom

Rau cov khoos kas HPHT, qhov kev txiav txim siab feem ntau nqaim mus rau ib qhodissolvable piv rau siab -kub sib xyawpauv-tawm: yaj kom tshem tawm qhov kev xyaum- tawm qhov kev pheej hmoo, lossis khiav qhov sib xyaw ua ke siab txaus kom muaj sia nyob rau theem thiab lees txais lub tshuab tswj- tawm.
Cov Khoom Txiav Txim Rau HPHT Wells
Dissolvable Magnesium Alloys
Dissolvable frac plugs yog tsim los ntawm magnesium-raws li alloys engineered los teb cov kua dej zoo thiab ploj tom qab txoj haujlwm. Tus yuam sij rau HPHT yogtswj tus nqi: nrawm dhau thiab lub ntsaws poob kev ncaj ncees ua ntej frac; qeeb heev thiab nws lingers nyob rau sab. Ua tsaug rau cov khoom siv cov khoom siv magnesium alloy dissolvable thiab ua ke nrog cov cuab yeej ua tiav, ua rau cov hlau chemistry adjustable rau downhole kub thiab kua chemistry. Saib xyuas lubdissolvable magnesium alloy khoom kabrau muaj pes tsawg leeg thiab daim ntawv thov nthuav dav.
Composite Lub Cev thiab Kev Txhim Kho
Composite plugs siv iav - los yog carbon-fiber- ntxiv cov matrices. Lawv lub qab nthab yog cov txheej txheem resin: saum toj no qhov ntsuas kub lub matrix softens thiab lub ntsaws tuaj yeem nkag los yog tsis tso tawm. Rau HPHT, qhia qhov ntsuas qhov ntsuas kub thiab paub meej tias nws tiv thaiv qhov ntsuas kub hauv qab qhov zoo li qub (BHST), tsis yog qhov ntsuas kub uas xav tau.
High -Tsub Elastomers thiab Seals
Lub foob, tsis yog lub cev, feem ntau yog thawj qhov ua tsis tiav HPHT. Txheem nitrile ua tsis tau thaum ntxov; HPHT- ntsuas cov foob siv HNBR, FKM, Aflas lossis perfluoroelastomer nyob ntawm qhov kub thiab txias thiab H2S / CO2 raug. Ib txwm phim cov elastomer rau ob qho tib si kub thiab cov khoom tsim tawm - roj muaj pes tsawg leeg.
Slips thiab Mandrel Metallurgy
Slips yuav tsum tom lub casing tsis muaj cracking, thiab lub mandrel yuav tsum nqa lub load sib txawv. Hauv kev pabcuam HPHT thiab qaub, qhov no taw qhia rau siab -lub zog, corrosion- tiv taus alloys thiab kuaj xyuas cov cua sov - tsis yog cov khoom siv hlau.

FAQ
Qhov ntsuas kub li cas yog HPHT rau frac plugs?
HPHT feem ntau yog coj los ua ib qho mob hauv qab saum toj li ntawm 15,000 psi lossis 300℃F (149℃). Ntau qhov sib sib zog nqus thiab hauv qab dej sov- cov qhov dej pab tam sim no ua haujlwm zoo tshaj ob daim duab, uas yog qhov kev xaiv cov khoom txiav txim siab.
Puas yog dissolvable frac plugs ntseeg tau hauv HPHT qhov dej?
Yog, thaum lub magnesium alloy yog tuned rau qhov tshwj xeeb downhole kub thiab kua chemistry. Qhov kev pheej hmoo yog qhov tsis muaj peev xwm tswj tau qhov sib cais, yog li cov neeg muag khoom yuav tsum tau lees paub qhov kev ua tau zoo tiv thaiv koj qhov chaw nyob ib puag ncig es tsis yog qhov tshwj xeeb.
Yam elastomer twg yog qhov zoo tshaj rau siab -kub sealing?
Nws nyob ntawm cov roj sib xyaw. HNBR thiab FKM npog ntau HPHT rooj plaub; Aflas thiab perfluoroelastomer yog siv thaum kub thiab H2S / CO2 raug mob hnyav tshaj plaws. Muab cov elastomer rau ob qhov kev txwv.
Yuav ua li cas kuv piv ib tug dissolvable plug piv rau ib tug composite plug?
Xaiv qhov uas tsis tuaj yeem tshem tawm qhov laum - tawm thiab txo qhov tsis yog - lub sijhawm tsim khoom nyob rau hauv qhov ntev ntev; xaiv lub siab -kub sib xyaw thaum koj xav tau kev lees paub siab tuav nrog lub phiaj xwm, tswj cov zeb- tawm. Cov lus saum toj no qhia txog kev ua lag luam -offs.
