Ukuqulunqwa kunye namanyathelo okusebenza kwesixhobo sokugqiba kakuhle

1.Well ukugqitywa indlela

1) Ukugqitywa kokugqobhoza kwahlulwe kwaba: ukugqitywa kwe-casing perforating kunye nokugqitywa kwe-liner perforating;

2). Indlela yokugqiba umngxuma ovulekileyo;

3). Indlela yokugqibezela iLiner eSlothiweyo;

4). Igrabile epakishwe kakuhle Iindlela zokuGqibezela zahlulwe zibe: igrabile yomngxuma evulekileyo ipakishwe kakuhle ukugqitywa, igrabile yecasing epakishwe kakuhle, kunye nescreen socingo lwegrabile epakishwe ngaphambili;

2.Ukugqitywa kwesixhobo se-wellhead

Iqula lenziwe ngamacandelo amathathu ukusuka phezulu ukuya ezantsi: isixhobo somthombo, umtya wokugqibezela kunye nesakhiwo esisezantsi.

Isixhobo se-wellhead sibandakanya iinxalenye ezintathu: intloko ye-casing, intloko ye-tubing kunye nemveliso (igesi) umthi. Umsebenzi oyintloko wesixhobo somthombo kukumisa umtya we-tubing we-downhole kunye nomtya we-casing, ukutywina indawo ye-annular phakathi kwe-tubing, i-casing kunye nemigangatho emibini ye-casing. Izixhobo eziphambili zokulawula ukuveliswa kweoli kunye negesi; i-reinjection (inaliti yomphunga, inaliti yegesi, inaliti yamanzi, i-acidification, i-fracturing, i-chemical injection, njl.) kunye nemveliso ekhuselekileyo.

Umtya wokugqiba ubandakanya ikakhulu i-tubing, i-casing kunye nezixhobo zokuhla zidibene ngokwemisebenzi ethile. Ukuqhuba umtya wokugqiba ukuqalisa imveliso eqhelekileyo yemveliso kakuhle okanye inaliti kakuhle linyathelo lokugqibela lokugqitywa komthombo. Iindidi zemithombo (imithombo yokuvelisa i-oyile, imithombo yokuvelisa igesi, imigodi yokutofa kwamanzi, imigodi ye-injection ye-steam, i-gas injection yegesi) yahlukile, kwaye iintambo zokugqiba zihluke. Nangona zonke ziyimithombo yokuvelisa ioli, iindlela zokuvelisa ioli ziyahluka kwaye iintambo zokugqiba zahlukile. Iindlela zangoku zokuvelisa i-oyile ikakhulu zibandakanya ukuveliswa kwe-oyile yokuzitofa kunye nokuphakanyiswa okwenziweyo (ipompo yentonga, impompo yepiston yehydraulic, impompo yombane engaphantsi kwamanzi, ukunyuswa kwegesi) ukuveliswa kweoyile, njl.

Isakhiwo somngxuma ongezantsi yinhlanganisela yezinto eziphilayo kunye neentambo ezidityaniswe kwinqanaba eliphantsi lomtya wokugqiba oluhambelana nendlela yokugqiba.

3. Amanyathelo okusebenza aphambili okugqitywa komthombo

1). Beka izixhobo ezingaphezulu ngokweemfuno zoyilo

2). Ukumisela umbhobho wokubhobhoza okanye ikholamu yetyhubhu

3). Faka isithinteli sokuvuthela/umsebenzi/uxinzelelo loxinzelelo

4). Ukukhuhla kunye nokuhlanjwa kweetyhubhu

5). Ulungelelwaniso lokugqobhoza

6). Ukuphosa iintonga zokutshisa

7). Ukuhlamba umva/ukuhlamba

8). Khupha kwaye uhlambe kwakhona

9). Ukwehlisa umpakishi

10). Ikholamu yolawulo lwesanti esezantsi

12). Ikholamu yemveliso esezantsi
