Yintoni iNjineli yokuGqibezela iWell?

Ngokweempawu zejoloji zedama leoyile negesi kunye neemfuno zobugcisa zophuhliso kunye nokusetyenziswa, inkqubo yokuseka umjelo ofanelekileyo wokudibanisa okanye indlela yokudibanisa phakathi kwedama leoyile negesi kunye nomngxuma wedama leoyile negesi ezantsi komthombo ibizwa ngokuba kukugqitywa.

1. Iimfuno zokugqiba

1) .Iimeko zonxibelelwano ezifanelekileyo kufuneka zigcinwe phakathi komaleko weoyile negesi kunye nomngxuma womthombo, kwaye umonakalo komaleko weoyile negesi kufuneka ube mncinci;

2) .Kufanele kubekho indawo enkulu kangangoko kunokwenzeka yokuvuza phakathi komaleko weoyile negesi kunye nomngxuma womthombo, kwaye ukumelana kweoyile negesi emngxunyeni kufuneka kube kuncinci;

3) .Kufuneka bakwazi ukuvala ioyile, igesi, umaleko wamanzi ngempumelelo, ukuthintela ukungena kwegesi okanye umjelo wamanzi, ukuthintela ukuphazamiseka phakathi kwamaleko;

4). Kufuneka ikwazi ukulawula ngempumelelo imveliso yesanti yomaleko weoyile, ithintele ukudilika kodonga lomthombo, kwaye iqinisekise imveliso yexesha elide yomthombo weoyile;

5) .Amanyathelo onyango olune-stratized anje ngokufaka amanzi ahlukeneyo, ukujova ngegesi, ukuqhekeka kwe-stratized kunye nokufaka i-asidi kufuneka afumaneke ukuze kube lula ukusebenza kokuphakamisa kunye nokusebenza komgodi ongaphantsi komhlaba;

6) .Kwiindawo zokugcina ioyile enzima, imveliso yeoyile enzima inokuhlangabezana neemfuno zokubuyiselwa kobushushu (i-huff ephambili yomphunga kunye ne-puff kunye ne-steam drive);

7). Iimeko zokuphambukisa iMithombo yeNdlela kunye neMithombo ethe tye kwinqanaba lokugqibela lophuhliso lweendawo zeoyile;

8). Inkqubo ilula kangangoko kwaye iindleko ziphantsi kangangoko;

2.Ukugqitywaindlelas

1). ukugqobhoza kwahlulwe ngolu hlobo: ukugqitywa kokugqobhoza kwecasing, ukugqitywa kokugqobhoza kwe-liner;

2) .Indlela yokugqiba umngxuma ovulekileyo;

3). Indlela yokugqiba i-Slotted Liner;

4) Ukupakisha igravel kwahlulwe ngokwemingxunya evulekileyo, ukupakisha igravel kwikheyiji kunye nescreen segravel esipakishwe kwangaphambili.

3.Isixhobo sokugqiba intloko yemithombo

Umthombo wenziwe ngamacandelo amathathu ukusuka phezulu ukuya ezantsi: isixhobo sentloko yomthombo, umtya wokugqiba kunye nolwakhiwo lomngxuma osezantsi.Isixhobo sentloko yomthomboikakhulu ibandakanyaintloko yekheyisi, intloko yetyhubhukunye nomthi weoyile (igesi). Umsebenzi ophambili wesixhobo sentloko yomthombo kukufaka umtya wetyhubhu engaphantsi komngxuma kunye nomtya wekhava, ukutywina iityhubhu, ikhava kunye nendawo ephakathi kweengqimba ezimbini zekhava ukulawula ukuveliswa kweoyile kunye nomngxuma wegesi, ukufakelwa kwakhona (ukufakwa ngomphunga, ukufakwa ngegesi, ukufakwa ngamanzi, ukwenza i-asidi, ukuqhekeka kunye nokufakwa ngamakhemikhali, njl.njl.) kunye nezixhobo eziphambili zemveliso ekhuselekileyo. Umtya wokugqiba uquka ikakhulu izixhobo zetyhubhu, ikhava kunye nezixhobo ze-downhole ezidityaniswe ngokwemisebenzi ethile. Ukusebenzisa umtya wokugqiba ukuzisa umvelisi okanye umthombo we-injection kwimveliso eqhelekileyo linyathelo lokugqibela kwinkqubo yokugqiba. Uhlobo lomngxuma (umngxuma wemveliso, umngxuma wegesi, umngxuma we-injection wamanzi, umngxuma we-injection wamanzi, umngxuma wegesi) wahlukile, kwaye umngxuma wokugqiba wahlukile. Nokuba ziiWells zemveliso, iindlela zemveliso zahlukile, kwaye umngxuma wokugqiba wahlukile.

Iindlela zangoku zokuvelisa ioyile ziquka ikakhulu ukuveliswa kweoyile yokujova ngokuzithandela kunyeukuphakamisa okwenziweyo (impompo yentonga, ipompo yepiston ye-hydraulic, ipompo yombane engaphantsi komhlaba, imveliso yeoyile ye-gas lift). Isakhiwo somngxuma osezantsi sidibaniso sezixhobo kunye neentambo ezidityaniswe nesiphelo esisezantsi somtya wokugqiba kwaye zihambelana nendlela yokugqiba.

4.Amanyathelo aphambili okusebenza

1) Beka izixhobo zomphezulu ngokweemfuno zoyilo

2). Misa umbhobho wokubhola okanye umtya

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

4) . Ukukrwela imingxunya yokucoca

5). Ukulinganisa ubunzulu obugqobhozayo

6). Intonga yokudubula

7). Ukucoca imithombo yamanzi nge-blowback/ukucoca imingxuma

8). Sebenzisa umbhobho kwakhona

9). Balekaumpakishi

10). Sebenzisa umtya wokulawula isanti

11). Sebenzisa umtya wemveliso

12). Ukususwa kwe-BOP yentloko yomthombo

13). Ukufakelwa komthi we-wellhead

14). Ukukhulula izinto

15). Ukwamkelwa kwendlela yokunqumla umlambo
