Iinkqubo zokuSebenza ze-Roller Cone Bit.

1. Ukuhlolwa kokusasazwa kwangaphambili

1) Uhlolo olubonakalayo kunye noxwebhu:

- Umlinganiselo i-drill bit ububanzi.

- Jonga umonakalo kwimidibaniso enemisonto.

- Qinisekisa ukuba amazinyo kunye namatywina aqinile.

- Qinisekisa ukuba iicones eziqengqelekayo azingqubani enye kwenye.

- Hlola iintanda okanye iziphene ze-porosity kwi-welding seams.

2) Ufakelo lombhobho:

- Qinisekisa ukucoceka komlomo kunye nendlu ngexesha lofakelo. I-Hammering inqatshelwe ngokungqongqo ukuphepha ukonakalisa umbhobho kunye namakhonkco okutywina.

2. Ukuphatha Bit

1) Sebenzisa ngokufanelekileyoi-drill bitizihlanganisi kunye nezixhobo zokuphatha ukuthintela umonakalo kwimicu, imilomo, kunye nomzimba omncinci.

2) Ukuthintela izixhobo ekuweleni emthonjeni ngexesha lokuphatha.

3) Faka i-lubricant yomsonto.

4) Landela iiparamitha zetorque ezicetyiswayo ngexesha lokuhlanganisa:

- 17 1/2" bit: Roller Cone: 46.1—54.2 KN · m; PDC: 65.5—71.9 KN · m.

- 12 1/4" bit: Roller Cone: 37.9—43.3 KN · m; PDC: 50.3—57.5 KN · m.

-8 1/2" kancinci: I-Roller Cone: 16.3—21.7 KN · m; PDC: 17—26.4 KN · m.

3. Ukugrumba kunye nokuVulwa komngxuma

1) Lawula isantya esisezantsi ngesithinteli sokuvuthela, intloko yecasing, amacandelo ancitshisiweyo obubanzi, amagxa, kunye nezihlangu zecasing.

2) Vula ngobunono umngxuma kumacandelo ancitshisiweyo edayamitha, ngokuqaphela ngakumbi xa usebenzisa amasuntswana ePDC; ukumpompa kufuneka kuqale phambi kokuvula umngxuma.

I-3) Qinisekisa ukuhla okugudileyo ukuphepha i-spikes yoxinzelelo.

I-4) Ilungu lokugqibela elilodwa okanye isigxina kufuneka sibe nesantya esiphezulu sokuhamba ukuvula umngxuma ukuya ezantsi kwequla.

3. Well Ezantsi Ukuphonononga

1) Njengoko usondela kumzantsi womthombo, jonga uxinzelelo lwe-drill kunye ne-torque; ukwanda kubonisa ukudibana nomzantsi okanye isanti eqokelelweyo.

2) Ukuba isanti ikhona, phakamisa umtya we-drill kwaye ujikeleze kwizinga eliphezulu lokuhamba ukuze uqinisekise ukucocwa kwezantsi.

3) Emva kokucoca, hambisa umtya we-drill up and down.

I-4) Ukugaya okungekho amandla, sebenzisa i-8 1/2 "bit kwi-17 KN kunye ne-12 1/4" kwi-25 KN, ngesantya se-40-60 RPM.

5) Ukuqhuba umbane, sebenzisa i-8 1/2" bit kwi-17 KN kunye ne-12 1/4" kwi-25 KN ngesantya esisezantsi esinokwenzeka.

5. Ukugrumba Ngeeplagi zesamente kunye neCasing Accessories

1) Qhubeka uphakamisa kwaye unciphise umtya we-drill ngexesha lokujikeleza kunye nokujikeleza ukucoca i-bit.

2) Ukulawula uxinzelelo lwe-drill ukuphepha umonakalo wokusika amazinyo kunye nokuthwala izitywina.

3) Jonga uxinzelelo lwempompo ukukhusela ukuvaleka kombhobho.

4) Lungisa isantya sokujikeleza ukuba kukho utshintsho oluphawulekayo ekubhobhozeni okanye kwi-torque.

I-5) Sebenzisa uxinzelelo oluphantsi lwe-drill kunye nokujikeleza okucothayo kwi-torque ezinzileyo: ukomba ombane kufuneka ube nesantya esifanelekileyo sokuhamba; ukugrumba okungasebenzisi mandla kufuneka kusebenzise amazinga okuqukuqela aphezulu.

6) Phakamisa kwaye uvule umngxuma rhoqo kwiimitha ezi-4-5 ngelixa ubhobhoza kwiplagi ye-samente, wenze njalo amaxesha angama-2-3, kwaye uhlambe iqula ngokuhamba okuphezulu kwiiveki ezi-1-2 rhoqo kwiimitha ezingama-25-30 ukuqinisekisa ukujikeleza okupheleleyo kwenkunkuma yesamente kumphezulu.

6. Kakuhle Ezantsi Ukubunjwa

I-1) Sebenzisa uxinzelelo oluphantsi lwe-drill, ukujikeleza okucothayo, izinga lokuhamba okuphezulu, kunye ne-torque ephantsi.

2) Ukubunjwa kwiqula elisezantsi kuxhomekeke kuhlobo lwebhithi kunye nesixhobo sokudibanisa.

3) Kwiibhithi ze-roller cone, sebenzisa i-40-60 RPM kunye noxinzelelo lwe-drill ye-35 KN ye-17 1/2 ", i-24 KN ye-12 1/4", kunye ne-17 KN kwi-8 1/2 ", igcina ubuncinane imizuzu engama-30 yokugaya.

4) KubaAmasuntswana ePDC, sebenza ngaphantsi kweetoni ezi-2 zoxinzelelo lwe-drill kwi-60-100 RPM, ukwandisa uxinzelelo kunye nokulungelelanisa isantya emva kokugaya ubuncinane i-1-1.5 yeemitha.

7. ULingo lwe-Drilling ukumisela iiParameters ezifanelekileyo

I-1) Uvavanyo lwe-drilling yindlela esebenzayo yokumisela indibaniselwano efanelekileyo yoxinzelelo lwe-drill kunye nesantya sokujikeleza ukuze kuphunyezwe amazinga aphezulu okugaya oomatshini.

2) Ukuqhuba uvavanyo lokugaya xa kukho utshintsho ekubunjweni, izinga lokugaya oomatshini, i-torque, abasebenzi, okanye iiparitha zokusebenza ezifana neepropati zodaka kunye ne-hydraulics.

I-3) Qala u-drilling isilingo ngesantya esiphantsi, kunye noxinzelelo lwe-drill olusethelwe ubuninzi obucetyiswayo kwi-bit.

4) Xa iireyithi eziphezulu zoomatshini ziphunyezwa kuxinzelelo olwahlukileyo lwe-drill kunye nendibaniselwano yesantya, khetha eyona iphantsi yoxinzelelo-isantya soxinzelelo lwendibaniselwano yokwandisa ubomi.

I-5) Uxinzelelo olufanelekileyo lwe-drill kunye nesantya kufuneka zikhokelwe ngamanqaku okugqibela kunye nemida ye-torque.
