1. Ukwakhiwa komhlahlandlela
Gwema ukuphambuka kwejika kanye nokwakheka kwesimo "S" ekwakheni okuqondisiwe.
Enqubweni yokwakhaukubhoboza okuqondisiwengokusebenzisa, kungakhathaliseki ukuthi imbobo yomhlahlandlela ibushelelezi noma cha, ukuthi ihambisana nejika lomklamo wokuqala, futhi ugweme ukubonakala kwesimo "S" sembobo yomhlahlandlela kuyisidingo sokuphothulwa ngempumelelo kokwakhiwa kokuwela. Ukuze kugwenywe ukwakheka kwesimo "S", izinyathelo ezilandelayo zingathathwa:
（1）Enqubweni yokulinganisa nokubeka, sebenzisa isiteshi esiphelele ukuhlola kabusha nokuqinisekisa izindawo zokuphuma nezokungena izikhathi ezingaphezu kwezintathu ukuqinisekisa ukuthi ipayipi eliwelayo liyahambisana nomklamo.
(2) Ngaphambi kokubhoboza, ithuluzi lokubhoboza liyalinganiswa, kanye namaphuzu amaningi okulinganisa okuphindaphindiwe ukuqinisekisa ukunemba kwalo.
（3）Hlaziya izimo zejiyoloji ngaphambi kokuqala umsebenzi, dweba ijika elihambayo ngendlela yokuxhuma ipayipi ngalinye lokubhoboza ephepheni elihambisanayo ngokwejika lomklamo, faka ilebula ipayipi ngalinye lokubhoboza, bese ukhombisa izimo zejiyoloji ezihambisanayo ekujuleni okuhlukene; Enqubweni yokubhoboza, ngokwesikhundla sokubhoboza sezimo zokwakheka ukulawula ukusebenza kwe-viscosity yodaka, nganoma yisiphi isikhathi ngokwezimo zejiyoloji ukulungisa ingcindezi yodaka, isilinganiso sodaka kanye neminye imingcele.
（4）Ngemva kokuba i-rig yokubhoboza isikhona, kala ngokunembile usayizi we-engeli efakiwe, ubale ukukhukhuleka okuvundlile bese uyiqopha, bese uyilungisa kancane kancane ngokwenani elivumelekile lokugoba okuwela ngesikhathi senqubo yokubhoboza, ukuze ugweme ukuma "kwe-S" kwepayipi lokubhoboza ngohlobo lokwakheka ukuqinisekisa ukushelela kwe-curve yokubhoboza nokuthuthukisa ikhwalithi yokubhoboza yembobo yomshayeli.
（5） Qonda ubuso, izimo ze-geological kanye nezamanzi, bese ulinganisa i-azimuth emugqeni ophakathi nendawo ngaphandle kokuphazamiseka kwamagnetic. Ukulinganiswa kwe-Angeli ye-azimuth kwenziwa kuzo zombili izinhlangothi zendawo yokungcwaba kanye nendawo yokumba.
（6）Ikhoyili kufanele ibethelwe ngaphezu kwe-axis yokuwela, futhi ukuphambuka kufanele kulinganiswe njalo ukuqinisekisa ukuthi i-axis yokuwela iyahambisana ne-axis yokuklama kanye nokunemba kokumba kwenqwaba ephezulu endaweni evuliwe.
（7） Amarekhodi okulawula isiqondiso kumele aphelele, anembile futhi asebenze kahle. Enqubweni yokubhoboza imigodi yokuhlola, noma yikuphi ukungajwayelekile kanye nokumiswa kokubhoboza kufanele kuqoshwe.
（8）Qaphela umehluko wokucindezela kodaka kanye noshintsho lodaka ngaso sonke isikhathi ukuze unikeze isisekelo sokwahlulela isimo sokusebenza kwephampu yodaka; qaphela ushintsho lokucindezela kokunyakaza ukuze unikeze isisekelo sokusebenza kwethuluzi lokubhoboza.
（9） Ukuze kuqinisekiswe ukuthi ijika lokubhoboza lihambisana nejika lokuwela eliklanywe ngendlela ethile, uhlelo lokuqondisa luzohlolwa lapho kubhobozwa imbobo yomshayeli, okuhlanganisa kakhulu: ukuhlola ikhonsoli yomshayeli, ukuhlola idivayisi yokuxhumana kwedatha, ukuxilongwa kwe-probe (kufaka phakathi ukuhlolwa kokulinganisa i-probe, idatha, njll.) ukutholwa okuqhubekayo. Ngemva kokuba zonke izivivinyo nokulungiswa sekuqediwe, qhubeka nokubhoboza okuvamile.
2.Ukwelaphant ilinganisa lapho i-drill bit inamathele
(1) Ngesikhathi sokubhoboza umgodi wokuhlola, i-drill bit ingase ibambeke, okubonakala ngokwanda okukhulu kokucindezela kodaka, noma ukwanda okusheshayo kwe-torque ye-drilling rig (ngesikhathi sokubhoboza okujikelezayo). Ngalesi sikhathi, i-torque ekhiqizwa yi-mud motor ayikwazi ukunqoba isenzo se-torque yedwala ku-drill bit, i-drill bit iyayeka ukujikeleza.
Kunezinketho ezimbili:
● Uma ukwehla kwengcindezi yodaka kungagcinwa ngaphakathi kwebanga elingu-500psi, kungenzeka ukumisa ngokushesha ukuqhubekela phambili kwepayipi lokubhoboza, bese udonsa ipayipi lokubhoboza liye ngasendleleni ye-drilling rig ukuze wenze i-drill bit ishiye idwala ngokushesha, unciphise umehluko wengcindezi yodaka, bese usebenzisa i-Thrust and thrust speed drilling ehamba kancane;
●Uma ukwehla kwengcindezi yodaka kudlula ama-500psi, ipompo yodaka kufanele icinywe ngokushesha, ukupompa udaka kufanele kumiswe, bese ipayipi lokubhoboza lihoxiswe liye endaweni yokubhoboza ukuze kuvinjelwe ukuthi injini yodaka ingonakali ngenxa yokucindezela okukhulu esivalweni.
(2) Ngesikhathi sokwakhiwa kwembobo yokuqondisa, i-drill iyabhajwa lapho kufakwa ithuluzi lokubhoboza noma kupompa ipayipi lokubhoboza ngaphansi kwezinye izimo ezikhethekile. Isizathu esiyinhloko ukuthi ukuphambuka kwezingxenye ngazinye kukhulu kakhulu, ukuhlanzwa kwembobo akuphelele, ukuqongelela ngokweqile kwezicucu zokubhoboza okubangelwa “umgodi wokuncipha”, okuholela ekubhobozeni okubhajwe.
Ukwelashwa: Okokuqala, udaka kufanele lugcinwe lusebenza ngendlela evamile, futhi kunodaka olwanele lokupompa emgodini. Ngalesi sikhathi, ipayipi lokubhoboza akufanele liqhubeke nje nokuhoxa emuva, kungenjalo lizobhajwa kalula. Ipayipi lokubhoboza kufanele liqhubeke liqhubekela phambili ngodaka lokupompa, lihlanze umgodi ngesineke, lilungise unqenqema oluphezulu lwebhithi ngokwerekhodi lokuqala lokubhoboza, limise ukuzungeza kwepayipi lokubhoboza liphompa emuva, linake ukulawula ukucindezeleka kwe-rig, bese lijikelezisa ipayipi lokubhoboza phambili, lihlanze umgodi, izikhathi eziningi, kuze kube yilapho libushelelezi ngesigaba "sokuncibilika komgodi".
3.Ukwakhiwa kwe-Reaming
(1) Izindlela zokulwa nokuwa kwekhoni emgodini ngesikhathi sokugaya kabusha
Ngesikhathi sokwakhiwa kwe-reaming, ngenxa yamandla edwala amaningi noma isakhiwo sengqimba yamadwala eguquguqukayo, i-cone ye-reamer ye-cone ingawela emgodini, ithinte ukwakhiwa kwe-reaming okulandelayo.
Indlela yokwelapha: Ngokwemininingwane yerekhodi lesiqondiso, ushintsho lokucindezeleka engxenyeni ngayinye yengqimba yedwala lungatholakala. Ngemva kokuba i-rock reamer isisetshenziswe amahora angu-80, yishintshe ngentsha ukuze uyixube; Ngaphambi kokuba i-reamer ingene endaweni lapho ukucindezeleka kwedwala kukhula khona, uma i-rock reamer isisetshenziswe amahora angaphezu kwangu-60, yishintshe ngentsha.
(2) Izindlela zokulinganisa ipayipi lokubhoboza eliphukile
I-geology ehlanganisayo yale phrojekthi ayilingani ngobulukhuni nobunzima, futhi izidingo zokwakheka kwe-reaming ziphakeme kakhulu. Uma uhlangana nezindawo ezinezinguquko ezinkulu ekucindezelweni kwamadwala ngesikhathi soku-reaming, kulula ukubangela ukuphuka kwepayipi lokubhoboza, okubonakala ngokuncipha okusheshayo kwe-torque yokubhoboza nokucindezeleka.
Indlela yokwelapha: ngesikhathiukubhoboza okuqondisiweUma kwakhiwa, inqubo yokwakha yokuxhuma ipayipi lokubhoboza endaweni yokumba kufanele isetshenziswe. Ngemva kokuba ipayipi lokubhoboza liphuke, lungisa imishini ngesikhathi esifanele endaweni yokumba bese udonsa i-drill pipe reamer emuva. Ngemva kokuba wonke ama-drill pipe reamer esedotshiwe, uhlelo lokuqondisa kufanele lufakwe eceleni enhlabathini ukuze luqondise futhi emgodini wokuqala wokuqondisa.
