Ukwakhiwa kunye namanyathelo okusebenza kwesixhobo sokugqiba i-wellhead

1. Indlela yokugqiba iqula

1). Ukugqitywa kokugqobhoza kwahlulwe ngolu hlobo: ukugqitywa kokugqobhoza kwecasing kunye nokugqitywa kokugqobhoza kwe-liner;

2). Indlela yokugqiba umngxuma ovulekileyo;

3). Indlela yokugqiba i-Slotted Liner;

4). Iindlela zokugqiba iMigodi epakishwe ngeGravel zahlulwe ngolu hlobo: ukugqitywa kwemigodi epakishwe ngegravel evulekileyo, ukugqitywa kwemigodi epakishwe ngegravel ekwisikhewu, kunye nesikrini sentambo yegravel esipakishwe kwangaphambili;

2. Isixhobo sokugqiba intloko yemithombo

Umthombo wenziwe ngamacandelo amathathu ukusuka phezulu ukuya ezantsi: isixhobo sentloko yomthombo, umtya wokugqiba kunye nesakhiwo esisezantsi.

Isixhobo sentloko ye-wellhead sibandakanya ikakhulu iindawo ezintathu: intloko yekheyiji, intloko yetyhubhu kunye nomthi wokuvelisa (igesi). Umsebenzi ophambili wesixhobo sentloko ye-wellhead kukuxhoma intambo yetyhubhu engaphantsi komngxuma kunye nentambo yekheyiji, ukuvala isithuba esiphakathi kwetyhubhu, ikheyiji kunye neengqimba ezimbini zekheyiji. Izixhobo eziphambili zokulawula ukuveliswa kwemithombo yeoyile negesi; ukufakelwa kwakhona (ukufakwa komphunga, ukufakelwa kwegesi, ukufakelwa kwamanzi, ukufakelwa kweasidi, ukuqhekeka, ukufakelwa kwamakhemikhali, njl.njl.) kunye nokuveliswa okukhuselekileyo.

Umtya wokugqiba uquka ikakhulu iityhubhu, i-casing kunye nezixhobo zomngxuma ongaphantsi komhlaba ezidityaniswe ngokwemisebenzi ethile. Ukusebenzisa umtya wokugqiba ukuqala imveliso eqhelekileyo yequla lokuvelisa okanye i-injection linyathelo lokugqibela lokugqiba iqula. Iintlobo zemithombo (imithombo yokuvelisa ioyile, imigodi yokuvelisa igesi, imigodi yokungenisa amanzi, imigodi yokungenisa umphunga, imigodi yokungenisa igesi) zahlukile, kwaye imitya yokugqiba nayo yahlukile. Nokuba yonke yimimithombo yokuvelisa ioyile, iindlela zokuvelisa ioyile zahlukile kwaye imitya yokugqiba nayo yahlukile. Iindlela zangoku zokuvelisa ioyile ziquka ukuvelisa ioyile yokuzijova kunye nokuphakanyiswa kokwenziwa (ipompo yentonga, ipompo yepiston ye-hydraulic, ipompo yombane engaphantsi komhlaba, i-gas lift) imveliso yeoyile, njl.

Ulwakhiwo lomngxuma osezantsi ludibaniso lwezinto eziphilayo lwezixhobo kunye neentambo ezidityaniswe nesiphelo esisezantsi somtya wokugqiba ohambelana nendlela yokugqiba.

3. Amanyathelo aphambili okusebenza kokugqitywa komngxuma

1). Beka izixhobo zomphezulu ngokweemfuno zoyilo

2). Ukuseta umbhobho wokugrumba okanye ikholamu yetyhubhu

3). Faka isixhobo sokuthintela ukuqhushumba/umsebenzi/uvavanyo loxinzelelo

4). Ukukrwela nokuhlanjwa kwemibhobho

5). Ukulinganiswa kokugqobhoka

6). Ukuphosa iintonga zokutshisa

7). Ukuhlamba umva/ukuhlamba impahla

8). Khuhla uze uhlambe kwakhona

9). Ukuthoba ipakethi

10). Ikholamu yokulawula isanti esezantsi

12). Ikholamu yemveliso esezantsi
