1. Ulwakhiwo lwesikhokelo
Kuphephe ukuphambuka kwegophe kunye nokwenziwa kobume "S" kulwakhiwo oluqondisiweyo.
Kwinkqubo yokwakhaukubhola ngokwendlelaukuba umngxuma wesikhokelo uthambile okanye awugudi, nokuba uyahambelana noyilo lokuqala, kwaye uphephe ukubonakala kobume "S" bomngxuma wesikhokelo yimfuneko yokugqitywa ngempumelelo kolwakhiwo lokunqumla. Ukuthintela ukwakheka kobume "S", amanyathelo alandelayo anokuthathwa:
（1）Kwinkqubo yokulinganisa nokubeka, sebenzisa isikhululo siphela ukuvavanya kwakhona nokuqinisekisa iindawo zokuphuma nezokungena ngaphezulu kwezihlandlo ezithathu ukuqinisekisa ukuba umbhobho onqumlayo uyahambelana noyilo.
(2) Ngaphambi kokugrumba, isixhobo sokugrumba siyalinganiswa, kunye namanqaku amaninzi okulinganisa okuphindaphindiweyo ukuqinisekisa ukuchaneka kwaso.
（3）Hlalutya iimeko zejoloji ngaphambi kokuba uqale umsebenzi, zoba igophe elihamba ngendlela yokudibanisa umbhobho ngamnye wokugrumba kwiphepha elihambelanayo ngokwegophe loyilo, faka ilebheli kumbhobho ngamnye wokugrumba, kwaye ubonise iimeko zejoloji ezihambelanayo kubunzulu obahlukeneyo; Kwinkqubo yokugrumba, ngokwendawo yokugrumba yeemeko zokwakheka ukulawula ukusebenza kwe-viscosity yodaka, nangaliphi na ixesha ngokweemeko zejoloji ukulungisa uxinzelelo lodaka, umlinganiselo wodaka kunye nezinye iiparameter.
（4） Emva kokuba isixhobo sokugrumba sikhona, linganisa ngokuchanekileyo ubungakanani be-engile efakiweyo, ubale ukutyibilika okuthe tye uze ubhale phantsi, uze ulungise kancinci ngokwexabiso elivumelekileyo le-cross curvature ngexesha lenkqubo yokugrumba, ukuze uphephe imo "ye-S" yombhobho wokugrumba kuhlobo lokwakheka ukuqinisekisa ukugudama kwe-drill curve kunye nokuphucula umgangatho wokugrumba komngxuma wovavanyo.
（5） Qonda umphezulu, iimeko zejoloji kunye nezamanzi, kwaye ulinganise i-azimuth kumgca ophakathi wokunqumla ngaphandle kokuphazamiseka kwemagnethi. Ukulinganiswa kwe-Angle ye-azimuth kwenziwa kumacala omabini endawo yokungcwaba kunye nendawo yokumba.
（6）Ikhoyili kufuneka ibhalwe ngekhowudi ngaphezulu kwe-axis yokunqumla, kwaye ukuphambuka kufuneka kulinganiswe rhoqo ukuqinisekisa ukuba i-axis yokunqumla iyahambelana ne-axis yoyilo kunye nokuchaneka kokumba kwenqwaba ephezulu kwindawo evunjululweyo.
(7) Iirekhodi zolawulo lwendlela kufuneka zigqibelele, zichaneke kwaye zisebenze kakuhle. Kwinkqubo yokubhola umngxuma wovavanyo, nakuphi na ukungaqheleki kunye nokuyeka kokubhola kufuneka kubhalwe phantsi.
（8）Jonga umahluko kuxinzelelo lodaka kunye notshintsho lodaka ngamaxesha onke ukuze ubonelele ngesiseko sokugweba imeko yokusebenza kwepompo yodaka; jonga utshintsho kuxinzelelo lokuqhubeleka ukuze ubonelele ngesiseko sokusebenza kwesixhobo sokugrumba.
(9) Ukuqinisekisa ukuba igophe lokubhola lihambelana negophe lokuwela uyilo, inkqubo yokuqhuba iya kuvavanywa xa kugqojozwa umngxuma wovavanyo, ikakhulu kubandakanya: ukuvavanya ikhonsoli yomgqobhozi, ukuvavanya isixhobo sojongano lwedatha, ukuxilongwa kweprobe (kubandakanya ukujonga ukulinganiswa kweprobe, idatha, njl.njl.) ukufunyanwa okuqhubekayo. Emva kokuba zonke iimvavanyo kunye nohlengahlengiso zigqityiwe, qhubeka nokugqobhoza okuqhelekileyo.
2.Unyangoukulinganisa xa i-drill bit ibambekile
(1) Ngexesha lokugqobhoza umngxuma wovavanyo, i-drill bit inokubhajwa, nto leyo ebonakaliswa kukunyuka okukhulu koxinzelelo lodaka, okanye ukunyuka kwangoko kwe-torque ye-drilling rig (ngexesha lokugqobhoza okujikelezayo). Ngeli xesha, i-torque eveliswa yi-mud motor ayinakoyisa isenzo se-rock torque kwi-drill bit, i-drill bit iyayeka ukujikeleza.
Kukho iindlela ezimbini:
● Xa ukuhla koxinzelelo lodaka kunokugcinwa kumgama we-500psi, kunokwenzeka ukuba uyeke ngoko nangoko ukuqhubekeka kombhobho wokubhola, kwaye endaweni yoko utsale umbhobho wokubhola uye kwicala le-drill rig ukuze wenze i-drill bit iphume edwaleni ngokukhawuleza, unciphise umahluko woxinzelelo lodaka, uze usebenzise i-Thrust kunye ne-thrust speed drilling ecothayo;
●Xa uxinzelelo lodaka ludlula i-500psi, ipompo yodaka kufuneka icinywe ngoko nangoko, ukupompa udaka kufuneka kumiswe, kwaye umbhobho wokubhoboza kufuneka ubuyiselwe kwi-drilling rig ukuthintela ukuba injini yodaka ingonakali ngenxa yoxinzelelo olugqithisileyo kwisitywini.
(2) Ngexesha lokwakhiwa komngxuma okhokelayo, umngxuma uyanamathela xa kutshintshwa isixhobo sokugrumba okanye kupompa umbhobho wokugrumba phantsi kwezinye iimeko ezikhethekileyo. Isizathu esiphambili kukuba ukuphambuka kwamacandelo ngamanye kukhulu kakhulu, ukucocwa komngxuma akucocwanga, ukuqokelelwa kakhulu kweziqwenga zokugrumba okubangelwa "ngumngxuma onciphileyo", okubangela ukugrumba okunamathelayo.
Unyango: Okokuqala, udaka kufuneka lugcinwe lusebenza ngendlela eqhelekileyo, kwaye kubekho udaka olwaneleyo lokumpompa emngxunyeni. Ngeli xesha, umbhobho wokubhola akufuneki uqhubeke nje urhoxa umva, kungenjalo uya kubhajwa lula. Umbhobho wokubhola kufuneka uqhubeke usiya phambili ngodaka lokupompa, ucoce umngxuma ngomonde, ulungise umda ophezulu wento ngokwerekhodi yokuqala yokubhomba, uyeke ukujikeleza kombhobho wokubhola upompa umva, uqaphele ukulawula uxinzelelo lwerig, uze ujikelezise umbhobho wokubhola phambili, ucoce umngxuma, amaxesha amaninzi, ude uthambekele kwicandelo "lomngxuma onciphileyo".
3.Ukwakhiwa kweReam
(1) Iindlela zokulwa nokuwa kwekhowuni emngxunyeni ngexesha lokuxuba
Ngexesha lokwakhiwa kwe-reaming, ngenxa yamandla agqithisileyo elitye okanye ulwakhiwo lwe-rock layer oluguquguqukayo, i-cone ye-cone reamer inokuwela emngxunyeni, ichaphazele ukwakhiwa kwe-reaming okulandelayo.
Indlela yokunyanga: Ngokwedatha yerekhodi yesikhokelo, utshintsho loxinzelelo kwicandelo ngalinye lomaleko welitye lunokuchongwa. Emva kokuba i-rock reamer isetyenzisiwe iiyure ezingama-80, yitshintshe ngentsha ukuze uyixube; Ngaphambi kokuba i-reamer ingene kwindawo apho uxinzelelo lwelitye lukhula khona, ukuba i-rock reamer isetyenzisiwe iiyure ezingaphezu kwama-60, yitshintshe ngentsha.
(2) Iindlela zokulinganisa umbhobho wokugrumba oqhekekileyo
I-geology yokunqumla le projekthi ayilingani ngobunzima nobunzima, kwaye iimfuno zomgangatho wokwenza i-reaming ziphezulu kakhulu. Xa udibana neendawo ezinotshintsho olukhulu kuxinzelelo lwamatye ngexesha lokufaka i-reaming, kulula ukubangela ukwaphuka kwepayipi yokubhola, okubonakala ngokuncipha kwangoko kwe-torque yokubhola kunye noxinzelelo.
Indlela yonyango: ngexeshaukubhola ngokwendlelaEmva kokuba umbhobho wokugrumba uphuke, inkqubo yokwakha yokudibanisa umbhobho wokugrumba kwindawo yokugrumba kufuneka yamkelwe. Emva kokuba umbhobho wokugrumba uphuke, lungisa izixhobo kwindawo yokugrumba ngexesha elifanelekileyo uze utsale i-drill pipe reamer. Emva kokuba zonke ii-drill pipe reamers zilotyiwe, inkqubo yesikhokelo kufuneka ifakwe ecaleni emhlabeni ukuze ikhokhe kwakhona kumngxuma wokuqala wesikhokelo.
