Isikhokelo esiBanzi sokuKhetha iBit yeTricone Drill kunye nokusetyenziswa

Kwi-rotary drilling, ii-drill bitisebenza njengesona sixhobo siphambili sokutyhoboza amatye. Umgangatho wesuntswana kunye nokuhambelana kwayo nohlobo lokwakheka, iipropati zamatye, kunye neemeko zokomba zichaphazela ngokuthe ngqo isantya sokomba. Ukukhetha uhlobo lwebhithi olufanelekileyo kunye neeparameters zokomba ngokusekelwe kwiimeko zokubunjwa ngundoqo ekuphuculeni ukusebenza kakuhle kunye nokunciphisa iindleko. Ukugrumba okunzulu kuhlangana nokwakheka okuninzi kunye neentlobo zamatye ezineempawu ezahlukeneyo, ukwenzai-drill bitukukhetha umsebenzi onzima.

1. Indlela yokuKhetha iBit yeEmpirical

Ikwabizwa ngokuba yiNdlela yeDatha yokuNyolwa kweNdawo, le yindlela esebenzayo nesetyenziswa ngokubanzi phakathi kwamagcisa omsebenzi. Ixhomekeke ekuhlalutyweni kwedatha esuka kumaqula akufutshane kwindawo enye, kugxininise kwiintlobo ezincinci ezithe zafumana owona mfanekiso uphezulu ommbiweyo kunye nomndilili wokungena phantsi kweemeko ezifanayo zejoloji nobunzulu. Le ndlela ilula, iyasebenza, kwaye ifaneleke kakuhle imimandla enokwakheka okufanayo.

2. Indlela yokukhetha iBit eSekwe kwiReferensi

Ukoyisa imida yeendlela zobungqina, le ndlela ibandakanya idatha yokugawulwa kwe-acoustic njengesalathiso sokwakheka okungathanga ngqo, siphucula ukuchaneka kwezenzululwazi. Eyaziwa ngokuba yi "Ndlela yoReferensi," ifuna ababoneleli abancinci ukuba bathelekise iiparamitha zokwakheka ezivela ekugawulweni kwe-acoustic kunye neetemplates zokhetho ezisemgangathweni, okwenza iingcebiso ezichanekileyo.

3. Ukulingana okunokwenzeka Ukukhetha kancinciIndlela

Le ndlela ilandela indlela eyakhiweyo:

• Fumana idatha yokwenziwa kokwenziwa ngovavanyo okanye iindlela zokuqikelela.
• Sebenzisa uhlalutyo lweenkcukacha-manani kwidatha yokugrumba eqokelelweyo ukumisela isakhono esiphakathi sokubhola (Kd) kunye nempazamo eqhelekileyo (S) kulwakhiwo ngalunye.
• Ngetshati yokukhetha kancinane yekhowudi ye-IADC, thelekisa inqanaba lesakhono sokwakheka ukuze uchonge iindidi zesuntswana ezifanelekileyo kulwakhiwo lwejoloji nganye.

4. IiParameters zokuDla ezicetyiswayo kuzo zonke iiFomu

Ukusebenza ngokugqibeleleyo kwe-ai-drill bitixhomekeke ekukhetheni udidi lwebit oluchanekileyo kunye nokusebenzisa iiparamitha zokomba ezifanelekileyo.

5. Iprofayili yokuDrillability kunye nokuKhethwa kweBit kwiPuguang Formation

Kusetyenziswa idatha yokwakheka komhlaba neyokugawulwa kwemithi esuka kumaqula kummandla wasePuguang, ukusebenza kwebit kwahlalutywa kwaye kwahlelwa ngokwemigangatho yejoloji kunye nobukhulu bequla kusetyenziswa i-"Drill Bit Technical Efficiency Index" (JX=VL=umyinge wesantya sokungena koomatshini × isuntswana lemifanekiso).

• Ulwakhiwo kunye neProfayili yeLithology: Iinkcukacha ngamagama umaleko, ubukhulu, kunye neendidi zamatye ekudityanwe nazo kwindawo yasePuguang.
• Iprofayili yokuDrillability kunye noKhetho lweBit oluCetyisiweyo: Ihlela ukwakheka ngeekhowudi ze-IADC ngokusekwe kumanqanaba obuchule bokuqhuba.
• Iingcebiso zoKhetho lweBit Empirical: Ngokusekwe kwidata yosetyenziso lwebit yommandla, oku kubonelela ngolungelelwaniso lwebit olucetyiswayo lweesayizi eziqhelekileyo.
• Iingcebiso zeParameter yobuNjineli: Bala ubunzima obuphezulu-kwibit (WOB), i-RPM, isalathisi samandla oxinzelelo, kunye nomqobo we-WOB osekwe kwi-rock drill.

6. Izikhokelo zoKhetho lweBit ye-Drill eLungileyo kunye nokusetyenziswa

(a) Ukhetho oluSekwe kwiLithology kunye nesakhono soKwemba: Ukhetho lwentwana yokubhola kufuneka luthathele ingqalelo ngokuphambili i-lithology yokwakheka kunye nokuhlelwa kwesakhono sokubhola, kunye nohlengahlengiso olusekwe kwiiprofayili zelithological ezifunyenwe ngexesha lokomba.

(b) Iingcebiso ngokuBanzi zeAmasuntswana ePDC: Ngokwesiqhelo,Amasuntswana ePDCzilungele ukwakheka okuthambileyo ukuya kwephakathi.

• Ukwakhiwa okuthambileyo kunye neplastiki ephezulu, sebenzisa iibhithi ezinobubanzi obukhuluPDCabasiki kunye nokuvezwa kwe-highcutter ukomeleza ukusebenza kakuhle kokuqhekeza amatye.
• Ukwenziwa kobume obuphakathi kunye neplastiki ephantsi, khetha amasuntswana ane-PDC cutters encinci ye-diameter kunye nokuvezwa okuphantsi ukukhusela ukuphuka kwe-cutter kunye nokwandisa ubomi besixhobo.

(c) Ukuphucula i-Drilling Parameters esekelwe kwi-Bit Structure kunye neMiqathango yoKwakha: Lungiselela iiparameters-ezifana ne-WOB, i-RPM, kunye namandla ombane-ngokusekelwe kwisakhiwo se-bit kunye neemeko zokubunjwa, kwaye uqinisekise ukuba zihlala ngaphakathi kweendlela ezicetyiswayo.

(d). Ukukhetha indlela ngobunzulu boMthombo kunye noLwakhiwo:

• Kulwakhiwo olunzulu, dibanisa amasuntswana ePDC aneemotor ezisezantsi ukuze kuxhaswe amandla aphezulu e-RPM.
• Ubunzulu obuphakathi, ubukhulu be-diameter bore izicelo, ukwandisa i-WOB kunye nokunciphisa i-RPM ngokufanelekileyo ukunyusa ukusebenza kakuhle kokomba.
