Ezinyibilikayo vs Iiplagi zeFrac ezidityanisiweyo

Amawakawakaamaqulazifuna 10,000-psi ratedfraciiplagi ezinokuthi zifakwe kwiqula ukuze idibaniseimisebenzi yokugqobhozakungenziwa ngaphambi kokubaukuqhekeka kwehydraulic.

Abaqhubi banamhlanjeUngakhetha kwimiriyadi yeeplagi ezidityanisiweyo ezinexabiso eliphantsi ezisilwa emva kokwaphuka okanye kwiindidi ezininzi zexabiso eliphezulu leeplagi ezenziwe ngemathiriyeli.yenzelwe ukunyibilikakumaqondo obushushu downhole ezahlukeneyoulwelo lokugqitywa.

Ziziphi iiplagi zeFrac ezinyibilikayo?

Ingxaki: Iplug-and-perf engangeneleliyo

Iiplagi zefrac ezingenakungenelela zitshintshiweiplug-and-perf ukusebenza kakuhlekunye nokwenza irekhodi isebenze ubunzulu bonyango ngokususa i-post-frac drillouts.

Kodwa xa kungangeneleliyoizixhobo zokuhlisa umngxumashiya izithintelo kumthombo okanye uthintele ukufikelela, zinokwenza nzima ukusebenza ngoku, kwaye kamva.

Isisombululo esifanelekileyo

Iplagi yefrac ukuba ngokupheleleyouyanyamalala emngxunyeniemva kokuqhekeka.

Ukusetyenziswa kweeplagi zefrac eziqhelekileyoiziliphu zentsimbikunye namakhonkco okanye amaqhosha e-ceramic, edibene nompakisho, ukuyayenza itywina lobunjineli obuqinileyokwaye ubambe iiplagi ngokuqinileyo kwindawo.

Kodwa ezinye zezi zixhobo zomelele kakhulu azinakunyibilika, kunye nezinto eziqhekeka ngokululaulwelo lwemithombobadla ngokuba phantsiamandla oomatshini, kwaye inokuqhekeka ngokukhawuleza okukhulu.

Ucelomngeni

Amandla oomatshini,izitywina zobunjineli, kwayeingqibelelo-kunye nokwahlukana ngokupheleleyo.

Ukudibanisa iipropati ezibonakala zingahambelani kwisixhobo esinye kunokufezekiswa ngeizixhobo eziphambili, isayensi,ubunjineli obungaqhelekanga,uyilo lokusebenza oluphezulu, kunye nokuzinikela okungapheliyoukuhambisa oko kufunwa ngabaqhubi.

Ukuphucula ukusebenza kakuhle kunye nokusebenza kakuhle kweplagi kunye ne-perf kunye ne-openhole multistage stimulation

Iyanyibilikaiinkqubo zeplagi kunye ne-perfsebenzisa iiplagi ezonakeleyo endaweni yeeplagi ezidityanisiweyo ukwahlula imimandla ngexesha lovuselelo.

Inkqubo eguquguqukayo ifanelekile kwisamente, engafakwanga, ethe nkqo, etenxileyo, okanyeizicelo ezithe tyaba kwi-shale, ilitye lentlabathi, idolomite, kunye nezinye iilithologies.

Ukufikelela kwimveliso ye-fullbore I.D

Izinto eziphathekayo zithotywa ngokupheleleyo kwaye ziqikelelwe kwiiyure okanye iintsuku, ziqinisekisa ukuba imveliso ifikelela kumandla ayo apheleleyo.

Ukufikelela kwi-Fullbore nako konyusa iinketho ezikhoyo zovavanyo lwe-postfracturing kunye nekamvaukulungiswa kwemvelisokunye nokungenelela.

Ukuphelisa ukungenelela koomatshini

Akukho ziplagi zithetha ukuba akukho ngenelelo ngoomatshini olufunekayo ukuzikhupha. Ukubaleka iiplagi ezinyibilikayo kuphelisa imfuno ityhubhu- okanyeI-Coil Tubing-idlulise umpu oqhumayo ukuqhekeza-ukuvuselela inqanaba lokuqala aukusebenza kweplagi-kunye-perf.

Isiphumo sinciphisa inkcitho yexesha kunye nemali. Imisebenzi inokwenzeka kwiindawo ezikude ngaphandle kokufikelela kwiiyunithi zongenelelo ngoomatshini.

Yandisa indawo yokugcina amanzi

Ubude becala buthintelwe ngamandla, iindleko, kunye nobude beI-Coil Tubingukugaya okusebenzayo. Ukuphelisa ukungenelela kwe-CT ye-postfracturing kususa imida kubude becala, ukwandisa uqhagamshelwano lwe-reservoir kunye noqikelelo lokugqibela lokubuyisela (EUR).

Susa imingcipheko ehambelana nokungenelela koomatshini

Kumadama aphelelweyo kunzima ukuwalawulaukususwa kobutyobo bokusila, ukwanda kweendleko kunye nobungozi bokuxinga. Riggingwenziwe ngobunjineli ngoomatshiniizixhobo zongenelelo phezulu naphantsi zithwele imingcipheko yaso.

Finyelela kwimarike ngokukhawuleza

Ukuphelisa ukugawula kakhulu kunciphisa ixesha phakathiukugrumba kunye nokuveliswa. Vulaiipads ezininzingexesha ukubhola kwi-pad kugqityiwe, okokuqalaamaqula alungele ukuqukuqela abuyekwaye ibekwe kwimveliso, ibonelele ukufikelela ngokukhawuleza kwingeniso.

Ziziphi iiPlagi zeFrac ezidityanisiweyo?

Uphando oluqhutywe kunye nabaqhubi be-10 base-US kunye nabacebisi abanobuchwephesha kwiiplagi-kunye-perf(PNP) ukugqitywa kubonisa ukuba iiplagi ezidibeneyo zokuqhekeka zinerekhodi eqinisekisiweyo yokuphucula okuqhubekayo kwizantya zokumpompa, ixesha lokukhupha kunye nokusetyenziswa kwamanzi.

Iiplagi ezinyibilikayo, nangona kunjalo, abakafezeki kwisithembiso sabo sokuqala sokunciphisa iindleko ezipheleleyo zokugqitywa kwemisebenzi, kwaye ezinye iingcali ziyathandabuza amabango okuba ezi teknoloji ziphezulu.izixhobo zokuhlisa umngxumazisoloko zinyamalala ngaphandle kokuthintela ukubuya umva okanye imveliso.

Iiplagi ezidityanisiweyo zokuqhekeka ziye zasetyenziswa ukususela ekupheleni kweminyaka yoo-1980. Umdibaniso wokuqalauyilo lweplagizazisekwe kwiiplagi zeebhulorho zentsimbi ezifakwe kwilifa ezifakwe kumaqula athe nkqo agqityezelwa kwindawo enye okanye ezimbini.

• Iiplagi zokuqala zineenxalenye ezininzi zecandelo, kubandakanywa intsimbi kunye nezixhobo ze-tungsten kunye neendandatho zetsimbi, ngaphezu kwezinto ezixubileyo, ezazihlala zenziwe ngamacwecwe adibeneyo.
• Ngokufika kweukwaphuka okuthe tyaba okuthe tye,iiplagi ezidityanisiweyo ezidityanisiweyo ngokulula zaba ngamacandelo abalulekileyoukugqitywa komthombo ongaqhelekanga.
• Abaqhubi kunyeiinkampani zenkonzo ezinamava kwimidlalo ye-shale yase-USqikelela ukuba ama-80% amaqula agqityezelwa ngezigaba kusetyenziswa indlela yePNP.

Iplagi, isixhobo sokuseta kunye nomtya wompu wokugqobhoza zithotywa kwi-wireline kwaye emva koko zimpontshelwe phantsi emthonjeni; iplagi isetiwe, iqonga ligqobhozekile kwindawo ezininzi ezibizwa ngokuba ngamaqela, kwaye ucingo luyasuswa ukuze imisebenzi yokumpompa iqalise ukuphuka ngokugqobhoza kwilitye elikufutshane.

Le nkqubo iphinda iphindwe amaxesha ambalwa kwiqula elithe nkqo kunye namaxesha angama-20 ukuya kuma-70 kwiqula elithe tye. Emva kokwaphuka iiplagi zigrunjwa ngentwana kumbhobho odityanisiweyo okanye ngetyhubhu ebhijelweyo (CT) ngeinjini yezantsikwaye bit. Iinkunkuma evela ekusileniumsebenzi ujikeleziswa ngaphandle kwequla, kwaye i-flowback kunye nemveliso iqala.

Ukusebenza ngokufanelekileyo kwePNP, iiplagi, isixhobo sokumisela kunye nezibhamu kufuneka ziqhutywe ngokukhawuleza ngaphandle "kokusetha kwangaphambili" ngaphambi kokufikelela kubunzulu obujoliswe kuyo.Umthamo wamanzikunye namandla ehashe okumpompa iiplagi kumngxuma ongezantsi kufuneka ancitshiswe.

Iiplagi kufuneka zibambe i-8,000 psi ukuya kwi-10,000 psi ngexesha lokuqhekeka. Ukunciphisa iindleko zokugqitywa ngokubanzi, iiplagi kufuneka zikhuphe ngokukhawuleza kwaye zishiye kuphela ukusika okuncinci okungabangeli ukuba i-CT ibambelele ukwenzela ukuba uhambo olufutshane oluthatha ixesha luncitshiswe.

• Kwiminyaka embalwa edlulileyo ababoneleli beeplagi abadityanisiweyo abambalwa baye baphucula uyilo lwabo ukuze bahlangabezane nezi njongo ngokuzisa iiplagi ezimfutshane ezinemathiriyeli engcono yokuhlanganisa; iindawo ezimbalwa kunye nomxholo wentsimbi; kunye nezangqa ezihambisa amanzi ezikhawulezisa amaxesha okubaleka, ukunciphisa okanye ukuphelisa ukusetha kwangaphambili, ukuphucula ukulinganiswa koxinzelelo, kunye nokunciphisa ixesha lokukhupha (kwaye kuncedaukhuseleko lomlilo wesiza). Kwimingxuma yomsebenzi omnye ephononongwe kwi-Permian Basin olu phuculo lunciphise i-PNP kunye namaxesha okugqitywa koqhekeko ukusuka kwiintsuku ezisibhozo ukuya kwiintsuku ezine.

Iinjineli zokugqiba kunye nabacebisiuthe iiplagi ezisebenza kakhulu zifuna amanzi amancinci kwaye zinokumponthwa ngokukhuselekileyo phantsi ngesantya esidlula i-24 m/min (80 ft/min) ngaphandle komngcipheko wokusetwa kwangaphambili. Amaxesha okucoca ngezi plagi aqikelelwa kakhulu kwaye aqala kwi-7 ukuya kwimizuzu eyi-12 kwiplagi nganye.

Njengomvelisi okhokelayo weeplagi zefrac ezinyibilikayo, sibeka phambili uphando kunye nokuveliswa kwezinto ezintsha, sisenza ubuhlakani obucwangcisiweyo kunye nabathengi abaninzi. Iminikelo yethu ibandakanya iimveliso ezikhethekileyo ze-R&D ezinje ngeeplagi zebhulorho ekwaziyo ukumelana ne-hydrogen sulfide kunye neeplagi zefrac ezinyibilikayo ezinamaxesha anokuchithwa ngokwezifiso. Iimveliso zeqela leVigor ziye zavavanywa ngokungqongqo kwiindawo zabathengi, zibonisa ukusebenza okubalaseleyo. Ngemibuzo malunga nophuhliso lwemveliso kunye nophuculo, nceda uqhagamshelane nathi ukuze ufumane imveliso ekumgangatho ophezulu kunye nenkonzo yeengcali.
