Ukwakheka kanye nomsebenzi wesakhiwo somthombo

Ukwakheka kwesakhiwo somthombo:

1. Umqhubi

Ibhokisi lokuqala esakhiweni somthombo eduze kodonga lwembobo evulekile libizwa ngokuthi i-conduit. Imisebenzi: ukuvikela indawo eseduze nekhanda lomthombo ekuhlanzweni ekuqaleni kokubhoboza, ukusungula ukujikeleza kodaka, ukuqondisa ithuluzi lokubhoboza, ukuqinisekisa ukubhoboza okuqondile komgodi, njll.

2. Ibhokisi elingaphezulu

Ibhokisi lesibili esakhiweni somthombo libizwa ngokuthi i-surface casing. Umsebenzi uwukuvala ungqimba lwamanzi, ukuqinisa udonga lwedwala elingaphezulu elikhululekile, ukuvikela umgodi nokufaka i-packer.

3. Ibhokisi lobuchwepheshe

Ingqimba yesikhwama esifakwe ngaphakathi kwesikhwama esingaphezulu ibizwa ngokuthi isikhwama sobuchwepheshe. Umsebenzi ukuvikela nokuvala ukwakheka okunzima nokuyinkimbinkimbi ngaphezu kwedamu ukuqinisekisa ukubhoboza okubushelelezi.

4. Isembozo sesendlalelo samafutha

Ingqimba yokugcina yesikhwama emthonjeni wamafutha ibizwa ngokuthi isikhwama sengqimba yamafutha, okubizwa ngokuthi isikhwama. Umsebenzi walo ukuqinisa udonga lomthombo wesitoreji samafutha, ukuvala izendlalelo zamafutha, igesi namanzi, nokuqinisekisa ukukhiqizwa komthombo wamafutha isikhathi eside.

5. Ukufaka usimende

Ukufaka usimende kuyinqubo lapho kufakwa khona udaka lukasimende esikhaleni esiphakathi kwekhava nodonga lomthombo. Umsebenzi walo ukuqinisa udonga lomthombo, ukuvikela ikhava, nokuvala ungqimba ngalunye lukawoyela, igesi namanzi emthonjeni ukuze kungashayisani.

6. Isigqoko sikasimende

Ngemva kokuqeda zonke izinhlobo ze-casing kanye ne-cement, kwakheka isilinda sendandatho yesamente eqinile esikhaleni esiphakathi kwe-casing kanye nodonga lomthombo, esibizwa ngokuthi indandatho yesamente ye-cementing. Umsebenzi wayo ukuvala ukwakheka, ukuqinisa udonga lomthombo kanye nokuvikela i-casing.

7. I-master bushing

Ekubholeni okujikelezayo, ingxenye yepayipi le-kelly inamathela phakathi kwe-turntable ejikeleza amathuluzi angaphansi kwembobo.

8. Ukujula okuphelele kokubhoboza

Ukujula kokubhoboza okuphelele kubhekisela ekuphakameni kusukela phansi komgodi ovulekile kuya phezulu kobuso be-bushing yetafula elijikelezayo.

9. Ukujula kwebhokisi

Ukujula kwekheshi kubhekisela ekujuleni okuphakathi kobuso obungaphezulu betafula elijikelezayo kanye nendawo yesicathulo sekheshi sokwakheka kwamafutha.

10. Iphansi lomthombo wokwenziwa

Ubuso obuphezulu bomthombo wamafutha obuhlala ebhokisini ngemva kokuba usimende usungene engxenyeni engezansi kakhulu yebhokisi. Ukujula komgodi ongaphansi wokwenziwa kubonakaliswa ukujula kwebanga ukusuka ebusweni obuphezulu betafula elijikelezayo kuya emgodini ongaphansi wokwenziwa.

11. Ukubuyiselwa kwesimende esiphezulu

Ukuphakama kwesimende kuyabuya esikhaleni esiphakathi kwekhaseji kanye ne-wellbor. Ukujula kokubuya kwesimende kuyalingana nebanga eliphakathi kobuso obungaphezulu be-turntable kanye nobuso besimende besikhala esiphakathi.

12. Ipulaki yesamente

Ngemva kokufaka usimende, ikholomu yesimende kusukela phansi komthombo obholiwe kuya phansi komthombo wokwenziwa yipulaki yesimende.
