Umahluko phakathi kweTCP Perforation kunye neCable Perforation

I-TCP yiTubing edluliselwe ukugqobhoza. Ukuze ukwahlula kwi-cable perforation, kuyinto yesiko ukubiza i-cableless perforation. Inkqubo yokusebenza ye-TCP perforating kukudibanisa umtya we-perforating gun kunye ne-detonator ukuya kwinqanaba elisezantsi lombhobho weoli. Kwaye i-detonator iyakuvuyela ukutshabalalisa ngoxinzelelo lomhlaba okanye indlela yokubambelela, kwaye i-detonator iya kudubula. Iprojectile yokugqobhoza kumtya wemipu iyaqhunyiswa. Iibhulethi ze-perforating zikhupha imingxuma emininzi eludongeni lwe-oyile, kwaye i-oyile ekrwada ekubunjweni idlula kumbhobho weoli ukuya emhlabeni.

I-TCP perforation kunye ne-cable perforation ineenzuzo ezilandelayo.

(1) Uxinzelelo olubi lweperforation.

Emva kokuba i-TCP perforating gun igxininiswe phantsi kwinqanaba lokuba ifakwe, uxinzelelo olubi lunokwenziwa phakathi koxinzelelo lokubunjwa kunye noxinzelelo lwe-wellbore. Emva kokuba umpu we-perforating uhlanjululwe, uxinzelelo olubi luvelisa amandla okubuyisela ngokukhawuleza alawulekayo, ukuveliswa kweoli yeoli kwandiswe.

(2) Ukugqitywa kokugqobhoza okunye.

Kwimithombo ephezulu yoxinzelelo lweoyile kunye negesi, i-cable-free perforation yokudubula iileya ezininzi ekujoliswe kuzo ngexesha kunye novavanyo lokuvelisa kwangoko.

(3) Umsebenzi odibeneyo ngexesha elifanayo.

I-cable-free perforation inokudityaniswa kunye nabavavanyi abahlukeneyo kunye nezixhobo zokuvavanya i-oyile, ezifana nokuvavanya, i-asidi kunye nokuvuselela okuncinci kwe-fracturing.

(4) Umtya wompu unokukhululwa.

Xa umtya wompu kufuneka ukhululwe, umdibaniso wokukhulula unokukhupha umpu we-perforating ukusuka kumtya kwaye uwe phantsi komthombo.

(5) Ilungele ukugqobhozwa kwamaqula amakhulu atyekeleyo, amaqula adibeneyo kunye namaqula axwesileyo.

(6) Ukhuseleko olulungileyo.

Ii-detonators ezisetyenziswe kwiinkqubo ze-cable-free perforating zihlelwa zibe yimpembelelo yomatshini okanye i-detonation yoxinzelelo.

I-pyrotechnics esetyenzisiweyo yimveliso yomlilo engeyiyo yombane, egwema impembelelo yezinto ezingakhuselekanga ezifana nombane we-static kunye ne-stray current, kwaye inokhuseleko oluphezulu. Ukongezelela, ekubeni izixhobo ze-wellhead zifakwe kwi-wellhead phambi kokubhoboza, ukulawulwa kwequla elinoxinzelelo oluphezulu kunokuqinisekiswa, ngokukodwa i-gas-high-pressure well equkethe i-HZS. Isixhobo sokuvelisa igesi kakuhle sifakwe phambi kokubhoboza, kwaye ukugqobhoza kuvavanywa ngokuthe ngqo kwaye kuveliswe. Kukhuseleke kakhulu kunokusebenzisa umpu wentambo ukugqobhoza.

I-TCP perforation ineenzuzo ezininzi kwiintambo ezininzi zentambo, kodwa nayo inemida ethile, ebonakaliswa kule miba ilandelayo.

(1) I-TCP perforation ingqongqo kakhulu kwinkqubo.

(2) I-TCP perforating iyabiza ukwakha kwaye idla izinto ezininzi kunye nezixhobo.

(3) Ukuwohloka kokusebenza kokuqhuma.

Ngethuba lokwakhiwa kwe-TCP perforation, intambo ye-TCP gun ihlala kwinkqubo ye-downhole kwaye ihlala equleni ixesha elide kune-cable perforation, okubangelwa ukulahlekelwa kwamandla okubangelwa ukuchithwa kwe-thermal ye-explosive, ukunciphisa umphumo webhomu ye-perforation. Ke ngoko, ezinye izinto ezibanzi kufuneka ziqwalaselwe ngexesha lokwakha, njengobushushu bomngxuma ophantsi kunye noxinzelelo kunye nokhetho oluhambelanayo lwezixhobo zokugqobhoza.

(4) Ukhuseleko.

Nangona i-TCP perforation igwema impembelelo yombane ongatshintshiyo, ukusebenza kwe-TCP perforating kufuna abasebenzi kunye nezixhobo ezininzi kunomsebenzi oqhelekileyo we-cable perforating, ngoko ke imiba yokhuseleko kufuneka igxininiswe.

(5) Ukuthembeka kolwakhiwo.

Ukugqobhoza kwe-TCP kungasetyenziselwa uninzi okanye namakhulu emipu yokugqobhoza ngexesha, kwaye isithuba sokugqobhoza sisuka kumashumi eemitha ukuya kumakhulu aliqela eemitha. Ngenxa yezixhobo okanye abaqhubi, umtya wompu we-perforating uyanqatshwa, ukubangela ilahleko engenakulinganiswa. Ke ngoko, ukuphuculwa kokubonwa kokuthembeka kwe-perforation kunye nokusebenza kakuhle ngumba obalulekileyo.

Inkqubo yompu ye-perforating evela kwi-Vigor iveliswa kwaye yenziwe kwi-high-temperature alloy steel, enokuxhasa zombini iindlela zokuhambisa i-WCP kunye ne-TCP. I-Vigor iye yalungisa uyilo lwangaphakathi lwesakhiwo kuyilo, olunokubonelela ngeziphumo ezingcono zokubhoboza kwizicelo zehlabathi zangempela kwintsimi. Okwangoku, imipu egqobhozayo evela kwi-Vigor isetyenziswe kwizixeko ezahlukahlukeneyo emhlabeni jikelele, kwaye iqela laseVigor lihlala liphucula ukuyila kwethu imveliso kunye nokuthutha ukuqinisekisa ukuba iimveliso zethu zifika kwindawo yomthengi zikwimeko engcono kakhulu. Ukuba unomdla kwi-Vigor's perforating guns okanye ezinye izixhobo zokugaya kunye nokugqiba kwishishini leoli kunye negesi, nceda unganqikazi ukuqhagamshelana nam.
