Plug thiab Perf Technology

Plug-thiab-perf (bridge plug + perforation) yog cov thev naus laus zis thev naus laus zis rau ntau-theem volumetric fracturing hauv cov qhov dej tsis sib xws, suav nrog cov roj shale / roj thiab roj / roj. Siv ib lub xaim xaim lossis coiled tubing mus txawv tebchaws, cov cuab yeej hlua ib txhij ua cov teeb tsa ntsaws thiab ntau- pawg perforating, ua kom tsis muaj kev txwv, siab -kev ua haujlwm tau zoo ntawm cov dej stimulation.

• Choj Plug:Teem rau hauv lub casing, lub ntsaws zoo cais cov theem qis qis, muab kev sib cais zonal meej. Dissolvable los yog composite choj plugs feem ntau yog siv, uas yog cia li yaj tom qab fracturing los yog mechanically drilled tawm kom rov qab tag nrho - bore access.
• Perforating:Kev taw qhia perforation nyob rau hauv lub hom phiaj theem tsim ndlwg channel ntawm lub wellbore thiab tsim, ua kom meej tswj ntawm tawg pib qhov chaw thiab propagation kev taw qhia.
• Core tswvyim:Ib qho kev mus ncig ua kom tiav ob qho tib si ntsaws thiab perforating, txo tus naj npawb ntawm kev mus ncig, txhim kho kev ua haujlwm zoo, txo nqi, thiab txhim kho kev nyab xeeb.

• Thawj theem ua haujlwm:Perforating, fracturing, thiab wellbore cleanout yog ua los ntawm tubing los yog coiled tubing.
• Pump down:Lub cuab tam hlua yog hydraulically pumped mus rau qhov tsim downhole qhov tob. Hauv seem kab rov tav, lub twj tso kua mis siab yog tso siab rau kev xa khoom.
• Plug Setting:Cov cuab yeej teeb tsa tau raug rho tawm haujlwm, txuas lub ntsaws ntsaws rau hauv lub casing thiab nthuav cov elastomer kom kaw. Tom qab cais cov theem tawg, cov cuab yeej teeb tsa tawm ntawm lub ntsaws.
• Multi-Cluster Perforating:Cov kab hluav taws xob tau rub mus rau lub hom phiaj theem, thiab ntau pawg tau raug rho tawm haujlwm ib txhij.
• Pull Phom & Fracture:Cov hlua phom perforating tau muab rov qab, thiab theem yog hydraulically tawg.
• Rov ua dua:Cov txheej txheem (tswj cia, teeb ntsaws, perforate, retrieve phom, tawg) yog rov ua kom tiav cov theem stimulation thoob plaws lub qhov dej.
• Ncej -Txoj Haujlwm Tsim:Tom qab fracturing, lub qhov dej yog ntws rov qab. Dissolvable choj plugs txiav degrade; Cov plugs sib xyaw tau raug tho tawm, rov ua kom puv - nkag nkag.

• Unlimited Theem:Tsis txwv los ntawm zawv zawg lub tes tsho suav; tuaj yeem ua tau raws li 30-50 theem, haum rau cov kav dej ntev.
• Precise Stimulation:Targeted perforating thiab tswj cov pob txha pib pib ua kom tswj tau pob txha thiab kev ua haujlwm siab.
• High Efficiency & Kev Nyab Xeeb:Ib qho kev mus ncig ua ob txoj haujlwm, txo kev mus ncig ntau zaus. Kev ua haujlwm nyob deb ua rau txo qhov tawg - cuam tshuam txog kev pheej hmoo.
• Full-Tshuaj lom neeg:Dissolvable/composite plugs tawm tsis muaj downhole obstructions, tsis txhob cuam tshuam nrog tom ntej ntau lawm los yog kev cuam tshuam.
• Strong Adaptability:Tau tshaj li cased-thiab- cemented tiav; unaffected los ntawm qhib qhov borehole stability, muab siab ua hauj lwm kev ntseeg siab.

• Hydraulic Pump Down:Siv lub twj tso kua mis siab los xa cov cuab yeej hlua, daws qhov kev sib tw ntawm lub ntiajteb txawj nqus conveyance nyob rau hauv kab rov tav seem.
• Multi-Fire Initiation:Tso cai rau ntau qhov xwm txheej tua hluav taws hauv ib qho kev sib tw, ua tau raws ntau - pawg perforating qhov yuav tsum tau ua.
• Dissolvable Choj Plug:Ua los ntawm aluminium alloy / cov ntaub ntawv sib xyaw; dissolves cia li nyob rau hauv 7-30 hnub thaum sib cuag nrog dej, tshem tawm qhov xav tau kev xyaum- tawm.
• Modular Perforating Phom:Modular sib dhos ntawm cov phom perforating, yoog tau rau qhov sib txawv casing qhov ntau thiab tsawg thiab tsim thicknesses.

Plug-thiab-perf thev naus laus zis tau dhau los ua tus qauv kev lag luam rau kev ua tiav tsis zoo kab rov tav. Los ntawm kev ua kom tsis pub dhau theem suav, qhov tseeb qhov tawg, thiab txo qhov tseem ceeb ntawm lub sijhawm mus ncig thiab kev pheej hmoo ua haujlwm, nws muab kev ntseeg siab, tus nqi -txoj kev zoo rau kev ua kom lub pas dej sib txuas thiab hydrocarbon rov qab nyob rau hauv complex, low- permeability reservoirs. Kev nce qib txuas ntxiv ntawm cov ntaub ntawv pov tseg thiab cov phom modular ntxiv txhim kho nws cov txiaj ntsig thiab kev siv tau. Yog xav paub ntxiv, thov tsis txhob yig tiv tauj pab pawg Vigor kom paub meej ntxiv txog cov khoom lag luam.
