Kuhlanganisani ukusebenza kwe-downhole?

1. Ukwelashwa kwekhadi lesihlabathi

Emithonjeni lapho ipayipi elibambekile lingeside khona noma isihlabathi esibambekile singesibi kakhulu, intambo yepayipi elingaphansi ingaphakanyiswa futhi yehliswe ukuze kukhululwe isihlabathi futhi kuncishiswe ingozi yokubhajwa kwepayipi.

Ukuze kulungiswe imithombo enezimbobo ezinkulu zesihlabathi, umuntu kufanele andise umthwalo kancane kancane ube nenani elithile ngesikhathi sokuphakamisa, bese ehlisa ngokushesha futhi akhulule ngokushesha; Kumiswe isikhathi esithile ngaphansi kwesimo sokwandiswa, ukuze amandla okudonsa adluliselwe kancane kancane entanjeni yepayipi engezansi. Zombili lezi zinhlobo zingasebenza, kodwa umsebenzi ngamunye kufanele umiswe imizuzu emi-5 kuya kweyi-10 ukuvimbela intambo ukuthi ingakhathali futhi ingaxhunywa.

Ukuze kubhekwe ukuminyana kwesihlabathi, izindlela ezifana nokucindezela okungasebenzi kahle kanye nokujikeleza kwegazi okuqondile, ukufutha amapayipi, ukuphakamisa ngamandla, ukujikijela, kanye nokugaya imikhono eqondile nakho kungasetshenziswa ukubhekana nokuminyana kwesihlabathi.

2. Ukwelashwa kokubhoboza okubambekile kwento ewisiwe

Ukunamathela kwezinto eziwela phansi kusho ukuthi amathuluzi angaphansi komhlaba anamathela emihlathini, ezishelelayo, amathuluzi amancane, njll. awela emgodini, okuholela ekunamatheleni kokubhoboza.

Uma ubhekene nezinto eziwelayo ezibhajwe ku-drill, ungayiphakamisi ngamandla ukuze uvimbele ukuthi ingabhajwe bese kuba nzima kakhulu. Kunezindlela ezimbili zokwelapha ezijwayelekile: uma intambo yepayipi ebhajwe ingajikeleziswa, intambo yepayipi ejikelezayo kancane ingaphakanyiswa ngobumnene. Cindezela izinto eziwelayo ukuze ukhulule ukugoba kwentambo yepayipi ephansi; uma indlela engenhla ingasebenzi, ungasebenzisa i-wall hook ukuze uqondise ingxenye ephezulu yenhlanzi, bese ususa izinto eziwelayo.

3. Ibhokisi lokukhulula linamathele

Ngenxa yezindlela zokukhuthaza ukukhiqiza noma ezinye izizathu, i-casing iyaphazamiseka, yonakele, njll., futhi ithuluzi lomgodi ophansi lehliswa ngephutha ngengxenye eyonakele, okuholela ekunamatheleni kwepayipi. Lapho ucubungula, susa intambo yepayipi ngaphezu kwendawo ebambekile, bese i-backing ingakhululwa kuphela ngemva kokuba i-casing isilungisiwe.
