Drilling ukujikajika: injongo, iintlobo, iimpawu

Tye ukubhola zemiyalelo - enye yeendlela uthandwayo amaqula ezivelisa, esetyenziswa ngethuba umsebenzi wokulungisa, engamzondi imigca zonxibelelwano phantsi iindlela zothutho ezikhoyo. Xa usebenzisa le ndlela zokomba livela intshabalalo kancinane yomhlaba uluhlu, nto leyo intle ukuze kubekho uzinzo kunye nesikhundla umthwalo. Enye izinto eziphambili leeyunithi inxaxheba ekusekweni zombini amaqula ethe nkqo nethe tyaba zokukhomba, ukugrumba ukujikajika na. Ngaphandle le nqubo, akunakwenzeka ukuba usebenze kwindawo kuphuhliso lomhlaba. ukusetyenziswa kwayo eyiyo ivumela ukufumana i olifunayo umngxuma ubungakanani ukuya ngemilimitha-10.

ukuqashwa

Nasiphi na isixhobo inezigaba ezintathu eziphambili - ukulwa inkqubo, le ukujikajika kunye drill umtya. inkqubo Ukuhamba sisigqeba exhasayo apho endawathetha xa kudalwa imithombo nkqo. Usebenzela ukuhanjiswa izixhobo zokomba, idala imfuneko ayithi nkxu emhlabeni izixhobo amandla kwaye linoxanduva uzinzo kwinkqubo yonke. Xa block kunye ukuwisa inkqubo ifakwe plane batshintshana yomhlathi (post wapakisha) umhlaba lignite ukusebenza ukuphumeza. Ukubhola ukujikajika ilikhonkco oluphakathi phakathi kwezi zinto zimbini. Kuyimfuneko ukuba ugcine ubunzima kwi drill wesivakalisi sokuqala, ukuhlisa unikezelo ulwelo nokuthintela linegunya ngeentsontelo. The tyaba zemiyalelo yokomba ukujikajika encamathele kuyo ikhonkco sifikelele - Indlela anxibelelanisa nsika isixhobo ukuba usa drill-moya kwangaphambili. Kukho iindidi ezintathu ezingundoqo ukujikajika - ahlambe, amandla kunye nokusebenza. uhlobo ngalunye uneempawu zawo.

washover ukujikajika

Ngamanzi ukubhola ukujikajika isetyenziswa lokondla isisombululo kwindawo ekumbiwe kuyo. Ngokwemo, yinto itankana evuthelweyo ezibuhlazarha leyo ibekwe ulahle yesinyithi owenziwe okanye lwezindlu. Le isakhelo iqhotyoshelwe kule plane yi lomnyango, okanye ebizwa ngokuba yi-icici. Le okuhlamba Umzimba ukujikajika kugesi ekhethekileyo oludityaniswe umbhobho kwanikwa ulwelo. Isisombululo wadlula phantsi koxinzelelo ophezulu ngokusebenzisa itankana nakumgongxo ochazwe yeyela umhlathi rotary, yaye emva koko xa ebusweni ngokwayo. Inkqubo ngokuhlamba kude zomhlaba. Siwasebenzise, okanye bentonite, drill ikhuba esibonakala amandla okudlulisela amandla emzimbeni wakho. Ngenxa yale isalathiso ayinabantu Lokulinganisa iitoni ezingama-20, 30, 50 okanye ngaphezulu.

ukujikajika Industrial namandla

izixhobo uhlobo olunganeno amandla esetyenziswa kwinqanaba lokugqibela lwenkqubo yokomba. edge ayo aphezulu a rotary i drive kunye nezixhobo. Ngenxa ukujikajika uncedo ithatha umsebenzi plane, ukunciphisa iindleko kunye nokukhawulezisa nokusekwa kakuhle. Iimfaniso yale uhlobo olunganeno zahluke kwisakhono element view uqhagamshelo. uhlobo isixhobo zokusebenza lenza imisebenzi emibini - ukudala amandla ojikelezayo (via isixhobo olungisiweyo) kunye nonikezelo yezisombululo yokuhlamba. Uyakwazi ukwenza nawuphi na umsebenzi downhole xa idityaniswe umtya drill kunye ukujikajika thaca. Isixhobo, ukufumana indibaniselwano efanayo, lingayivelisi nokwenziwa kwezicelo abaziingcali.

Iimfuno ukubhola ukujikajika

It is a ukujikajika yokomba ayikho ngaphandle esiludumbo kokuxhuma, yenzelwe ukusebenza phantsi kweemeko ezinzima. Kufuneka ugcine yengxinano ngamandla lwenzeka kwinkqubo Ukubolekisa isixhobo sokugrumba. Ukongeza, kufuneka ukunyamezela singazinzi kunye nomthwalo nokuxuba. Ngexesha ukujikeleza drill umtya kuvela eninzi njengento eme engxaki neguquguqukayo, apho fakelo kufuneka ukumelana. Ngaphezu koko, kunokwembiwa ukujikajika kufuneka ukhuseleko ngokudleka nokwaleka ezizodwa ukuphucula banxibe uxhathiso.

ukhethe Iimpawu

Kuba ukubhola nenempumelelo kubalulekile ukujikajika wadibana zonke iimfuno ezichazwe apha ngasentla. Ukongeza, kufuneka kwakhona ukuhlangabezana neemfuno olu hlobo izixhobo imithetho esisiseko:

• Imilinganiso ezinqamlezayo akufuneki zinqanda intshukumo kwibhloko kwaye ukuwisa inkqubo ngexesha nokukhubeka umsebenzi, kwakunye namandla drill umtya.
• Kokubonisa kunye yenethiwekhi yeyunithi nenqaba drill kufuneka oluthembekileyo lula yezixhobo sichitha emva kokuba ugqityiwe umsebenzi.
• Le igrisi kufuneka ngokulungelelana isasazwe kuyo isakhiwo, ukuze ukujikajika umfutho encinane ubungakanani akukho shushu ngokugqithisileyo.

Ukwandisa kunokwembiwa, ukwenziwa komsebenzi kucetyiswa ukuba ukhethe iindawo zokusebenza, icandelo anokuba ngokukhawuleza nangokulula indawo Ukuba ukuguga uzisebenzisa. Kubalulekile ukukhumbula ukuba ukuthembeka ukuqina le ukujikajika kuxhomekeke kubuchule nobomi wenkonzo yonke zokomba isixhobo.

isiphelo

Nokuba uceba ukwakha iqula kwisiza, ayikhuthazwa tu ukuqokelela isixhobo ezandleni ukujikajika. Le izixhobo ezintsonkothileyo ezifezekisayo iimfuno ophezulu ukuguga ukumelana. Ukususela iyahlala kwaye nokuthembeka kuxhomekeke umsebenzi yonke isixhobo, ukususela yokuwisa kwinkqubo kunye nesiphelo kunye plane, drill intonga kunye kombiwa kuyo. Iiprojekthi ezikhethekileyo kufuneka kwenziwe ngokungqinelana imizobo ekuvunyelwene kunye umyili abanamava. Bona ziqulathe ulwazi malunga nokumelana kunye nonyango eya kubonelela intsebenzo elide-kwiqhina, kuthathelwa ingqalelo intsebenzo zoonke isixhobo sokugrumba.
