Umsebenzi Wokusebenza Nokuhlanza

I-Multiple Drop Ball Circulating Sub iyithuluzi lokudonsa phansi elisebenza kahle kakhulu elenzelwe imisebenzi yokubhoboza eqondisa ngqo, evundlile, nene-engeli ephezulu. Ivumela ukuvulwa nokuvalwa okuphindaphindiwe kwama-bypass ports ukuthuthukisa ukusebenza kahle kokubhoboza, ukunciphisa izingozi zokulawula imithombo, kanye nokwenza imisebenzi ekhethekile njengokulawula ukujikeleza kwegazi okulahlekile kanye nokuhlanza imisele yamanzi—ngaphandle kokukhubeka.

Ibhulashi Lohlobo Lwe-GS (I) lingenye yamathuluzi asizayo abalulekile ekuqedeni umthombo, ekuhlolweni nasekusebenzeni komgodi ongaphansi.

Leli thuluzi lilungele ukususa ukungcola okungase kushiywe phezu kwezindonga zangaphakathi zebhokisi, njengesamente eqinile, i-wax eqinile, amakristalu ahlukahlukene kasawoti noma amadiphozithi, ama-perforation burrs, izinsalela ze-iron oxide ezibangelwa ukugqwala, ukuze wonke amathuluzi emigodi engezansi adlule angavinjelwanga. Ikakhulukazi uma kukhona isikhala esincane esiyindilinga phakathi kwamathuluzi emigodi engezansi kanye nebhokisi elingaphakathi kobubanzi, ukuklwebheka okuphelele kuba yinto edingekayo ngaphambi kokusebenza okwengeziwe. Njengamanje emthonjeni omkhulu we-petroleum ukuklwebheka odongeni lwangaphakathi lwebhokisi ngokusebenzisa i-casing scraper kuyisinyathelo esidingekayo.

I-Drill String Fishing Magnet ingenye yamathuluzi asizayo okuqinisekisa ukusebenza okujwayelekile kokubhoboza kanye nokuhlanza imbobo engezansi enkambisweni yokwelashwa kwengozi yembobo engezansi. Lo mkhiqizo ukuthi usebenza kanye nezicathulo zokugaya emsebenzini wokudoba, okuhlukile endleleni yangaphambilini yokuphakamisa i-drill ngemva kokugaya, bese uxhuma intambo yokubhoboza ngethuluzi lokudoba elinamandla elinozibuthe ukuze wehle emthonjeni ukuze uhlanze imbobo engezansi, okusindisa ukuhamba emsebenzini womgodi, okungagcini nje ngokusindisa izindleko zokubhoboza, kodwa futhi kusindisa isikhathi sokusebenza kokudoba.

Uchungechunge lwe-Series 150 Overshot LANDRILL 150 uchungechunge olukhipha futhi olujikeleza i-overshot luyithuluzi lokudoba langaphandle lokudoba, ukupakisha nokulanda izinhlanzi ezishubhu, ikakhulukazi zokudoba ikhola yokubhoboza kanye nepayipi lokubhoboza. I-grapple ye-overshot ingaklanywa ngobukhulu obuhlukene bezinhlanzi, ngakho-ke i-overshot eyodwa ingagqokwa ngosayizi ohlukile wezingxenye ze-grapple zokudoba ngobukhulu obuhlukene bezinhlanzi. Ukwakhiwa kwe-Series 150 Overshot kuqukethe izingxenye ezintathu zangaphandle: I-Top Sub, i-Bowl, kanye ne-Standard Guide. Okuyisisekelo ...

Iphrofayili yomkhiqizo I-Section mill uhlobo lwethuluzi lokuvula ifasitela le-casing elihlanganisa imisebenzi yokusika i-casing kanye ne-milling. I-section mill ingena e-casing kanye ne-BHA, bese inquma i-casing endaweni ekhethiwe kuqala. Ngemva kokuthi i-casing isiqediwe ngokuphelele, izogaywa ngqo kusuka kulesi sikhundla. Ngemva kokufinyelela ekujuleni okuthile, umsebenzi wokuvula ifasitela le-casing usuqediwe. I-section mill inezinzuzo zesakhiwo esilula, ukusebenza okulula ukuyenza ibe yi-ca...

Amathuluzi okugaya asetshenziselwa ukugaya izinhlanzi nezinye izinto ezingaphansi kwemigodi, ukuhlanza udongeni lwesikhala (udonga lwesikhala) noma ukulungisa isikhala. Isimiso siwukugaya izinhlanzi zibe udoti ngaphansi kokujikeleza kanye nokucindezela kwentambo yokubhoboza nge-tungsten carbide eshiselwe engxenyeni yokusika yethuluzi lokugaya, futhi udoti ungabuyiselwa emhlabathini ngoketshezi lokubhoboza.
Izinhlobo eziningi zamathuluzi okugaya zivamile ngesakhiwo, kuyilapho ngokwezimo ezahlukene zezinhlanzi, kudingeka izingxenye zokusika ezifanayo. Izingxenye zokusika ezisetshenziswa njalo zingahlelwa ngaphakathi, ngaphandle nasekupheleni kwamathuluzi okugaya.
Ngemva kokuklama okusha kanye nokuqongelela ubuchwepheshe eminyakeni yamuva nje, baye bahlangabezana nezidingo zangempela zamakhasimende avela eShayina nakwamanye amazwe ngenxa yokusebenza okuthembekile. Ngaphandle kwezinhlobo nosayizi okubalwe kokuqukethwe okulandelayo, samukela futhi ukukhiqiza ngokwesikhundla esikhethekile esinganelisa izidingo zamakhasimende.
