I-Dissolvable vs Composite Frac Plugs

Izinkulungwaneimithombozidinga i-10,000-psi elinganiselwei-fracamapulaki angafakwa emgodini womthombo ukuze lelo qoqoimisebenzi yokubhobozakungenziwa ngaphambii-hydraulic fracturing.

Opharetha banamuhlaingakhetha kunqwaba yamapulaki ayinhlanganisela angabizi kakhulu agaywa ngemva kokuphuka noma ezinhlotsheni ezimbalwa zamapulaki abiza kakhulu akhiwe ngezinto zokwakha.yakhelwe ukuncibilikaemazingeni okushisa e-downhole ezinhlobonhlobo zeuketshezi lokuqeda.

Ayini ama-Dissolvable Frac Plugs?

Inkinga: I-plug-and-perf engangeneleli

Amapulagi e-frac angangeneleli ashintshiweukusebenza kahle kwe-plug-and-perffuthi inike amandla ukujula kokwelashwa kokumiswa kwerekhodi ngokususa ukukhishwa kwe-post-frac.

Kodwa lapho kungangeneleliamathuluzi we-downholeshiya izithiyo emgodini womthombo noma ukhawule ukufinyelela, zingase futhi zenze imisebenzi ibe nzima—manje, nakamuva.

Isixazululo esifanele

Ipulaki ye-frac ngokupheleleiyanyamalala emgodiningemva kokuphuka.

Ukusetshenziswa kwe-frac plugs ejwayelekileiziliphu zensimbinamasongo noma izinkinobho ze-ceramic, kuhlanganiswe ne-packer, ukuzeyenza uphawu oluqinile lobunjiniyelafuthi ubambe amapulaki aqine endaweni yawo.

Kodwa ezinye zalezi zinto eziqine kakhulu azinakuncibilika, nezinto ezihlakazeka kalula phakathi.uketshezi lwe-wellborengokuvamile abaphansiamandla mechanical, futhi ingase ihlakazeke ngokushesha kakhulu.

Inselele

Amandla omshini,izigxivizo zobunjiniyela, futhiubuqotho- kanye nokuhlukana okuphelele.

Ukuhlanganisa izakhiwo ezibonakala zingahambisani zibe ithuluzi elilodwa kungafezwa ngaloizinto eziphambili, isayensi,ubunjiniyela obungajwayelekile,high ukusebenza design, kanye nokuzibophezela okungapheliukuletha lokho okudingwa ngabaqhubi.

Thuthukisa ukusebenza kahle kanye nokusebenza kahle kwezindleko ze-plug-and-perf kanye nokuvuselela isiteji se-openhole

Ezincibilikayoama-plug-and-perf systemssebenzisa amapulaki awonakaliswa esikhundleni samapulaki ayinhlanganisela ukuze uhlukanise izindawo ngesikhathi sokuvuselela.

Isistimu eguquguqukayo ilungele ukusimende, okungasekiwe, okuqondile, okuchezukile, nomaizicelo ovundlile in shale, i-sandstone, i-dolomite, namanye ama-lithologies.

Finyelela ukukhiqizwa kwe-fullbore I.D

Impahla yonakala ngokuphelele futhi ngokubikezelwa phakathi kwamahora noma izinsuku, iqinisekisa ukuthi ukukhiqizwa kufinyelela amandla ako aphelele.

Ukufinyelela kwe-Fullbore nakho kukhulisa izinketho ezitholakalayo zokuhlolwa kwe-postfracturing kanye nekusasaukuthuthukiswa kokukhiqizakanye nokungenelela.

Susa ukungenelela kwemishini

Awekho amapulaki asho ukuthi akukho ukungenelela kwemishini okudingekayo ukuze kugaywe. Ukugijima amapulaki ahlakazekayo kuqeda isidingo se-tubing- nomaI-Coil Tubing-sidlulisele isibhamu esibhobozayo ukuze siphuke-sivuselele isigaba sokuqala se-aukusebenza kwe-plug-and-perf.

Umphumela uba ukuncishiswa kwezindleko zesikhathi nemali. Imisebenzi ingenzeka ezindaweni ezikude ngaphandle kokufinyelela kumayunithi okungenelela emishini.

Khulisa ukuxhumana kwe-reservoir

Ubude basemaceleni bukhawulelwe amandla, izindleko, nobude beI-Coil Tubingukugaya ngempumelelo. Ukuqeda ukungenelela kwe-CT ye-postfracturing kususa imikhawulo kubude be-lateral, kukhulisa ukuthintana kwe-reservoir kanye nokulinganiselwa kokugcina (EUR).

Susa ubungozi obuhambisana nokungenelela kwemishini

Emachibini aphelile kunzima ukuphathaukususwa kwemfucumfucu yokugaya, izindleko ezikhulayo kanye nezingozi zokubhajwa. Ukukhwabanisamechanical engineeredimishini yokungenelela phezulu naphansi iphethe izingozi zayo.

Finyelela emakethe ngokushesha

Ukususa ukugaya kunciphisa kakhulu isikhathi phakathiukumba nokukhiqiza. Vuliweama-multiwell padsngesikhathi ukubhola kuphedi sekuqediwe, okokuqalaimithombo isilungele ukugeleza emuvafuthi ibekwe ekukhiqizweni, inikeze ukufinyelela okusheshayo kwimali engenayo.

Ayini ama-Composite Frac Plugs?

Ucwaningo olwenziwe nama-opharetha ayi-10 ase-US kanye nabeluleki abanolwazi kuipulaki-futhi-perfUkuqedwa kwe-(PNP) kuveza ukuthi amapulagi ahlukene okuphuka anerekhodi elifakazelwe lokuthuthuka okuqhubekayo kwesivinini sokumpompa, isikhathi sokuphuma kanye nokusetshenziswa kwamanzi.

Amapulaki ancibilikayo, nokho, abakasifezi isithembiso sabo sokuqala sokunciphisa izindleko eziphelele zokuphothula imisebenzi, futhi abanye ochwepheshe bayangabaza izimangalo zokuthi lezi zobuchwepheshe obuphezuluamathuluzi we-downholenjalo iyanyamalala ngaphandle kokuvimbela ukugeleza noma ukukhiqizwa.

Amapulagi okuphuka ahlanganisiwe asetshenziswe kusukela ngasekupheleni kwawo-1980. Inhlanganisela yokuqalaimiklamo yepulakiayesekelwe kumapulaki ebhuloho lensimbi afakwe emithonjeni eqondile aqedwe endaweni eyodwa noma ezimbili.

• Amapulaki okuqala ayenezingxenye eziningi zengxenye, kuhlanganise nensimbi ekhonjiwe kanye nezingxenye ze-tungsten nezindandatho zensimbi, ngaphezu kwezinto eziyinhlanganisela, ezazivame ukwenziwa ngamashidi anezingqimba enhlanganisela.
• Ngokufika kwei-multistage horizontal fracturing,amapulaki aphuka kalula ahlanganiswe abe yizici ezibalulekileukuqedwa kwemithombo engajwayelekile.
• Abaqhubi kanyeizinkampani zesevisi ezinolwazi emidlalweni yase-US shalebalinganisela ukuthi ama-80% emithombo aqedwa ngezigaba kusetshenziswa indlela ye-PNP.

Ipulaki, ithuluzi lokusetha kanye nentambo yesibhamu ebhobozayo kwehliswa ocingweni bese kuphonswa phansi emthonjeni; ipulaki isethiwe, isiteji sibhobozwa ezindaweni ezimbalwa ezibizwa ngokuthi amaqoqo, futhi ucingo luyasuswa ukuze imisebenzi yokumpompa iqale ukuphuka ngezimbobo edwaleni eliseduze.

Le nqubo iphindwe izikhathi ezimbalwa emthonjeni oqondile futhi izikhathi ezingu-20 kuya kwezingu-70 emthonjeni ovundlile. Ngemuva kokuphuka amapulaki abhobozwa kancane epayipini elihlangene noma ngeshubhu elihlanganisiwe (CT) ngei-downhole motorfuthi kancane. Iimfucumfucu evela ekugayweniukusebenza kusakazwa ngaphandle komthombo, futhi ukugeleza nokubuyela emuva nokukhiqiza kuyaqala.

Ukuze uthole ukusebenza kahle kwe-PNP, amapulaki, ithuluzi lokusetha nezibhamu kufanele kuqhutshwe ngokushesha ngaphandle “kokusetha kusengaphambili” ngaphambi kokufinyelela ekujuleni okuhlosiwe.Umthamo wamanzikanye namandla ehhashi okumpompa amapulaki emgodini ophansi kufanele ancishiswe.

Amapulagi kufanele abambe u-8,000 psi ukuya ku-10,000 psi ngesikhathi sokuphuka. Ukuze kuncishiswe izindleko zokuqeda sezizonke, amapulaki kufanele abhoboze ngokushesha futhi ashiye izinqamuli ezincane kuphela ezingabangeli ukuthi i-CT ibambelele ukuze uhambo olufushane oludla isikhathi luncishiswe.

• Eminyakeni embalwa edlule abahlinzeki bepulaki abayinhlanganisela abambalwa baye bathuthukisa imiklamo yabo ukuze bahlangabezane nalezi zinhloso ngokwethula amapulagi amafushane anezinto ezingcono eziyinhlanganisela; izingxenye ezimbalwa kanye nensimbi encane; namasongo oketshezi asheshisa izikhathi zokusebenza, anciphise noma asuse ukusetha ngaphambilini, athuthukise izilinganiso zokucindezela, futhi anciphise isikhathi sokuphuma (futhi esizaukuvikelwa komlilo wesitezi). Emithonjeni yomsebenzi oyedwa ocwaningwe ku-Permian Basin lokhu kuthuthukiswa kwehlise i-PNP kanye nezikhathi zokuqeda ukuphuka ukusuka ezinsukwini eziyisishiyagalombili kuya ezinsukwini ezine.

Onjiniyela abaqedile kanye nabaxhumanisiuthe amapulagi asebenza kahle kakhulu adinga amanzi amancane futhi angampontshelwa phansi ngokuphephile ngesivinini esingaphezu kuka-24 m/min (80 ft/min) ngaphandle kwengozi yokusetha kusengaphambili. Izikhathi zokuphuma ngalawa mapulaki zibikezelwa kakhulu futhi zisukela kumizuzu eyi-7 kuye kweyi-12 ipulaki ngayinye.

Njengomkhiqizi ohamba phambili wamapulagi e-frac ancibilikayo, sibeka phambili ucwaningo nokusungula izinto ezintsha, sakha ubudlelwano obunobuhlakani namakhasimende amaningi. Iminikelo yethu ihlanganisa imikhiqizo ekhethekile ye-R&D efana namapulagi ebhuloho amelana ne-hydrogen sulfide namapulaki e-frac ancibilikayo anezikhathi zokuncibilika okwenziwa ngokwezifiso. Imikhiqizo yethimba le-Vigor ihlolwe ngokuqinile kumasayithi wamakhasimende, okubonisa ukusebenza okukhethekile. Ngemibuzo mayelana nokuthuthukiswa komkhiqizo kanye nokuthuthukiswa, sicela usithinte ukuze uthole imikhiqizo esezingeni eliphezulu kakhulu kanye nesevisi yochwepheshe.
