Kuhlanganisani ukusebenza kwe-downhole (2)?

1. Uhlobo lokuwa kahle

Ngokwegama kanye nemvelo yezinto eziwayo, izinhlobo zezinto eziwayo emithonjeni ikakhulukazi zihlanganisa: izinto eziwa ngamapayipi, izinto eziwa esigxotsheni, izinto eziwa ngentambo kanye nezingcezu ezincane zezinto eziwayo.

2. Ukuhlengwa kwezinto eziwile zamapayipi

Ngaphambi kokudoba, umuntu kufanele aqale abambe idatha eyisisekelo yemithombo yamafutha namanzi, okungukuthi, aqonde idatha yokugaya kanye nokukhiqizwa kwamafutha, athole isakhiwo somthombo, isimo se-casing, nokuthi ngabe kukhona izinto eziwa ekuqaleni. Okwesibili, thola imbangela yezinto eziwayo, noma ngabe kukhona ukuguquguquka nokungcwatshwa kwendawo yesihlabathi ngemva kokuba izinto eziwayo ziwela emthonjeni. Bala umthamo omkhulu ongafinyelelwa ngenkathi udoba, qinisa i-derrick kanye nomgodi we-guyline. Kufanele futhi kucatshangelwe ukuthi ngemva kokubamba izinto eziwile, kufanele kube nezinyathelo zokuvimbela kanye ne-anti-jamming uma kwenzeka ukuqhuma ngaphansi komhlaba.

Amathuluzi okudoba asetshenziswa kakhulu ahlanganisa izigaxa zesifazane, izigaxa zesilisa, imikhonto yokudoba, imiphongolo yokudoba ngokushelelayo, njll.

Izinyathelo zokulondoloza ziyizi:

(1) Yehlisa isikhunta somthofu ukuze uvakashe ngaphansi komhlaba ukuze uqonde ukuma nokuma kwezinto eziwayo.

(2) Ngokuya ngezinto eziwayo kanye nosayizi wesikhala se-annular phakathi kwezinto eziwayo kanye ne-casing, khetha amathuluzi okudoba afanelekile noma uklame futhi uzenzele amathuluzi okudoba.

(3) Bhala umklamo wokwakha kanye nezinyathelo zokuphepha, futhi wenze ukwelashwa kokulondoloza ngokomklamo wokwakha ngemva kokugunyazwa iminyango efanele ngokwezinqubo zokubika, futhi udwebe imidwebo eyisikimu yamathuluzi okungena emthonjeni.

(4)Umsebenzi kufanele uzinze uma udoba.

(5) Hlaziya izinto eziwile ezisindisiwe bese ubhala isifinyezo.

3. Ukudoba amaconsi e-pole

Iningi lalezi zinto eziwayo ama-sucker rods, futhi kukhona nezinduku ezinesisindo nezinsimbi. Izinto eziwayo ziwela emgodini bese ziwela epayipini likawoyela.

(1) Ukudoba kushubhu

Kulula ukuhlenga induku yokuncela ephukile kushubhu. Isibonelo, uma i-sucker rod ikhubeka, induku yokuncelisa ingahle yehliswe ukuze ibambe noma yehlise i-slip canister ukuze ihlenge.

(2) Ukudoba emgodini

Ukudoba ku-casing kuyinkimbinkimbi kakhulu, ngoba ububanzi bangaphakathi be-casing bukhulu, izinduku zincane, insimbi incane, kulula ukugoba, kulula ukuyikhipha, futhi ukuma komthombo owelayo kuyinkimbinkimbi. Lapho ihlenga, ingasizwa ngehhuku ukuze iqondise isiliphu sesicathulo noma i-loose-leaf overshot. Lapho into ewayo igobile emgodini, ingahlengwa ngehuku lokudoba. Lapho izinto eziwayo zihlangene ngaphansi komhlaba futhi zingenakudotshwa, sebenzisa isilinda sokugaya noma isicathulo sokugaya ukuze ugaye, futhi usebenzise umdobi ozibuthe ukudoba udoti.

4. Izinto ezincane zihlenga

Kunezinhlobo eziningi zezinto ezincane eziwayo, njengamabhola ensimbi, imihlathi, amasondo egiya, izikulufu, njll. Nakuba izinto ezinjalo eziwayo zizincane, kunzima kakhulu ukuzihlenga. Amathuluzi okusindisa izinto ezincane neziwile ikakhulukazi ahlanganisa ukuhlenga uzibuthe, ukubamba, ubhasikidi wokuhlehlisa umjikelezo wokujikeleza nokunye.
