Dissolvable vs Composite Frac Plugs

Ntau txhiablub qhov dejxav tau 10,000-psi ntsuasfracplugs uas tuaj yeem ntsia tau rau hauv lub qhov dej kom cov pawgperforating kev ua haujlwmtuaj yeem nqa ua ntejhydraulic fracturing.

Cov neeg ua haujlwm niaj hnub notuaj yeem xaiv los ntawm myriad tus nqi qis sib txuas uas yog milled tom qab tawg lossis los ntawm ntau hom kev siv nyiaj ntau dua cov khoom sivtsim kom yajntawm downhole kub hauv ntau yamcov kua dej tiav.

Dab tsi yog Dissolvable Frac Plugs?

Lub Dilemma: Interventionless plug-and-perf

Interventionless frac plugs hloov pauvplug-and-perf efficiencythiab tau qhib cov ntaub ntawv teev kev kho qhov tob los ntawm kev tshem tawm cov kev xyaum ua tom qab frac.

Tab sis thaum interventionlesscov cuab yeej downholetawm cov kev cuam tshuam hauv lub qhov dej los yog txwv kev nkag mus, lawv tuaj yeem ua haujlwm nyuaj - tam sim no, thiab tom qab ntawd.

Cov tshuaj zoo tagnrho

Ib tug frac plug uas kiag lidisappears downholetom qab tawg.

Standard frac plugs sivcam khwb cia hlau swbthiab rings los yog tej hub nyees khawm, ua ke nrog ib tug packer, rautsim kom nruj engineered foobthiab tuav cov ntsaws ruaj ruaj rau hauv qhov chaw.

Tab sis qee qhov ntawm cov ntaub ntawv muaj zog siab no yog nondissolvable, thiab cov ntaub ntawv uas yooj yim disintegratecov kua dej zoofeem ntau yog qis hauvmechanical zog, thiab tej zaum yuav tawg sai heev.

Qhov kev sib tw

Mechanical zog,engineering seals, thiabkev ncaj ncees- thiab tag nrho disintegration.

Muab cov khoom seemingly incompatible rau hauv ib lub cuab yeej tuaj yeem ua tiav nrogcov ntaub ntawv siab heev, science,unconventional engineering,tsim kev ua haujlwm siab, thiab kev cog lus tsis tu ncua rauxa cov neeg ua haujlwm xav tau.

Txhim khu kev ua tau zoo thiab tus nqi-zoo ntawm plug-and-perf nrog rau openhole multistage stimulation

Dissolvable plug-and-perf systemssiv degradable plugs es tsis txhob sib txuas plugs rau cais cov cheeb tsam thaum lub sij hawm stimulation.

Cov txheej txheem ntau yam yog tsim rau cemented, uncemented, ntsug, deviated, los yogkab rov tav daim ntaub ntawv nyob rau hauv shale, sandstone, dolomite, thiab lwm yam lithologies.

Access fullbore ntau lawm I.D

Cov khoom degrades tag nrho thiab kwv yees nyob rau hauv cov sij hawm los yog hnub, kom ntseeg tau tias ntau lawm ncav cuag nws lub peev xwm.

Kev nkag mus rau Fullbore kuj nce cov kev xaiv muaj rau kev ntsuam xyuas tom qab kev txhim kho thiab yav tom ntejntau lawm optimizationthiab kev cuam tshuam.

Tshem tawm kev cuam tshuam kev siv tshuab

Tsis muaj plugs txhais tau hais tias tsis muaj kev cuam tshuam cov neeg kho tshuab yuav tsum tau txiav lawv tawm. Khiav cov plugs dissovable tshem tawm qhov xav tau ntawm cov tubing- lossisCoil Tubing-conveyed perforating phom kom tawg-stimulate thawj theem ntawm aplug-and-perf kev ua haujlwm.

Qhov tshwm sim yog txo kev siv sijhawm thiab nyiaj txiag. Kev ua haujlwm muaj peev xwm ua tau nyob rau hauv tej thaj chaw deb uas tsis muaj kev nkag mus rau cov cuab yeej siv tshuab.

Nce kev sib cuag reservoir

Qhov ntev ntev yog txwv los ntawm kev muaj peev xwm, cov nqi, thiab qhov ntev ntawmCoil Tubingrau milling zoo. Tshem tawm cov kev cuam tshuam tom qab CT tshem tawm cov kev txwv ntawm qhov ntev ntawm sab nraud, ua kom muaj kev sib cuag ntawm lub pas dej thiab kwv yees qhov kawg rov qab (EUR).

Tshem tawm cov kev pheej hmoo cuam tshuam nrog kev cuam tshuam kev siv tshuab

Nyob rau hauv depleted reservoirs nws yog ib qhov nyuaj rau tswj lubtshem tawm cov khib nyiab milling, nce nqi thiab kev pheej hmoo ntawm kev daig. Riggingneeg kho tshuab engineeringcov cuab yeej cuam tshuam nce thiab nqis yog nws tus kheej txaus ntshai.

Mus txog kev ua lag luam sai dua

Tshem tawm milling considerably txo lub sij hawm ntawmdrilling thiab ntau lawm. Ntawmmultiwell padslos ntawm lub sijhawm drilling ntawm lub ncoo ua tiav, thawjlub qhov dej tau npaj ntws rov qabthiab muab tso rau hauv kev tsim khoom, muab kev nkag tau sai rau cov nyiaj tau los.

Dab tsi yog Composite Frac Plugs?

Kev tshawb fawb tau ua nrog 10 US tus neeg ua haujlwm thiab cov kws pab tswv yim uas muaj kev txawj ntse hauvplug-and-perf(PNP) kev ua tiav qhia tau hais tias cov pob txha pob txha puas muaj cov ntaub ntawv pov thawj ntawm kev txhim kho txuas ntxiv hauv cov twj tso kua mis, lub sijhawm tho tawm thiab siv dej.

Dissolvable plugsTxawm li cas los xij, tseem tsis tau ua raws li lawv cov lus cog tseg thawj zaug los txo tus nqi tag nrho ntawm kev ua tiav, thiab qee cov kws tshaj lij tsis ntseeg txog cov lus thov tias cov cuab yeej siv siab no.cov cuab yeej downholeib txwm ua ploj yam tsis muaj impeding flowback lossis ntau lawm.

Composite fracture plugs tau siv txij li xyoo 1980s. Initial compositeplug designstau ua raws li keeb kwm cam khwb cia hlau txuas txuas txuas rau hauv qhov dej ntsug uas tau ua tiav hauv ib lossis ob thaj chaw.

• Thawj cov ntsaws ruaj ruaj muaj ntau qhov chaw, suav nrog cov hlau cam khwb cia thiab cov khoom siv tungsten thiab cov nplhaib hlau, ntxiv rau cov khoom siv sib xyaw, uas tau nquag ua los ntawm cov ntawv txheej txheej.
• Nrog lub advent ntawmmultistage kab rov tav fracturing,yooj yim drillable composite puas plugs los ua ib qho tseem ceeb Cheebtsam ntawmunconventional zoo tiav.
• Cov neeg ua haujlwm thiabcov tuam txhab kev pabcuam nrog kev paub hauv US shale playskwv yees tias 80% ntawm qhov dej tau ua tiav hauv theem uas siv PNP txoj kev.

Ib lub ntsaws, teeb tsa lub cuab yeej thiab cov hlua phom perforating raug txo qis ntawm cov xov hlau thiab tom qab ntawd tso rau hauv qhov dej; lub ntsaws yog teem, theem yog perforated nyob rau hauv ob peb qhov chaw hu ua pawg, thiab lub wireline raug tshem tawm yog li ntawd cov twj tso kua mis kev khiav hauj lwm yuav pib tawg los ntawm perforations mus rau hauv lub pob zeb nyob ib sab.

Cov txheej txheem no rov ua dua ob peb zaug hauv qhov dej ntsug thiab los ntawm 20 mus rau 70 zaug hauv qhov dej kab rov tav. Tom qab kev puas tsuaj, cov plugs tau drilled nrog me ntsis ntawm cov yeeb nkab sib txuas lossis los ntawm coiled tubing (CT) nrog ib qhodownhole lub cev muaj zogthiab me ntsis. Covkhib nyiab los ntawm millingkev khiav hauj lwm yog circulated tawm ntawm lub qhov dej, thiab flowback thiab ntau lawm pib.

Rau kev ua haujlwm zoo PNP, cov ntsaws ruaj ruaj, teeb tsa cov cuab yeej thiab cov phom yuav tsum tau khiav sai yam tsis muaj "presetting" ua ntej mus txog qhov tob ntawm lub hom phiaj.Dej ntimthiab horsepower rau kev siv lub plugs downhole yuav tsum tau tsawg.

Plugs yuav tsum tuav 8,000 psi rau 10,000 psi thaum tawg. Txhawm rau txo qis tag nrho cov nqi ua tiav, cov ntsaws ruaj ruaj yuav tsum tau tho tawm sai thiab tawm tsuas yog cov txiav me me uas tsis ua rau CT lo kom lub sij hawm siv sij hawm luv luv.

• Ob peb xyoos dhau los no ob peb cov khoom siv sib txuas tau txhim kho lawv cov qauv tsim kom tau raws li cov hom phiaj no los ntawm kev qhia luv luv plugs nrog cov ntaub ntawv zoo dua; tsawg qhov chaw thiab cov ntsiab lus hlau tsawg; thiab cov kua propulsion rings uas ceev lub sij hawm khiav, txo los yog tshem tawm presets, txhim kho kev ntsuas siab, thiab txo lub sij hawm drillout (tseem pab nyob rau hauvkev tiv thaiv hluav taws zoo). Hauv ib tus neeg ua haujlwm lub qhov dej tau kawm hauv Permian Basin cov kev txhim kho no tau txo PNP thiab tawg lub sijhawm ua tiav los ntawm yim hnub mus rau plaub hnub.

Ua tiav engineers thiab cov kws pab tswv yimhais tias cov plugs ua tau zoo xav tau dej tsawg dua thiab tuaj yeem muaj kev nyab xeeb ntawm kev nrawm tshaj 24 m / min (80 ft / min) yam tsis muaj kev pheej hmoo ntawm kev teeb tsa ua ntej. Lub sij hawm tho tawm nrog cov plugs no tau kwv yees tau zoo heev thiab thaj tsam li ntawm 7 mus rau 12 feeb rau ib lub ntsaws.
