Drill bit imiyalelo yesicelo
I-1 bit yokukhetha
1.Nceda ufunde inkcazo ye-lithology kunye neerekhodi ezincinci zamaqula akufuphi ngononophelo, kwaye uhlalutye iimpawu zokwakheka.
2. Ukukhetha uhlobo olufanelekileyo ngokuhambelana ne-lithology.
2 Amalungiselelo phambi kokomba
1.Hlola i-bit yangaphambili ngomonakalo womzimba, ii-cutters ezilahlekileyo okanye ezifakelweyo njl. Qinisekisa ukuba akukho nkunkuma kumngxunya we-buttom, kwaye ucoce umngxuma ongezantsi ukuba kuyimfuneko.
I-2.Bit kufuneka iphathwe ngononophelo ukwenzela ukuba kungabikho monakalo owenziweyo kunye nezinto ezinzima.
3.Khangela ukuba ngaba kukho nawuphi na umonakalo kwi-bit cuttes kwaye ukuba kukho nawuphi na umcimbi wangaphandle ngaphakathi kwebit.
4.Jonga ukuba ukufakela umbhobho kuyahlangabezana neemfuno, kwaye ubuyisele imilomo ukuba kukho imfuneko.
3 Ukumakisha intwana
1.Coca imisonto encinci kwaye usebenzise igrisi kwimisonto.
2.Faka i-breaker kwi-bit, yehlisa intambo ye-drill kwi-pin kwaye udibanise imicu.
3.Locate bit and breaker in the rotary bushing, and make-up the bit to be recommended torque.
4 Ukungena
1.Susa i-breaker kwaye unciphise ngokucophelela i-bit ngesixhobo se-wellhead ukuze ungonakalisi.
2. Ukushwabana, igxalaba, inja kunye nesitulo esingundoqo sequla kufuneka silumke xa sityhulwa kumngxuma ongenanto.
3.Qalisa impompo kunye nomjikelo wokugrumba ulwelo ukuhlamba umngxuma we-buttom xa ubhora ukuya kwindawo emalunga neemitha ezingama-30 ukuya ezantsi kumngxuma, kwaye ujikelezise umtya wokubhola ngesantya esiphantsi hayi ngaphezulu kwe-60rpm.
4.Sondela kumzantsi malunga nesiqingatha semitha.Jikeleza imizuzu emi-5 ukuya kwe-10 ngokuqukuqela okupheleleyo.
5 Ukucamngca
1.Ukukhupha amacandelo amade omngxuma we-undergauge akukhuthazwa.
2.Ukuba umsebenzi wokubuyisela kwakhona kuyimfuneko, kucetyiswa ngamandla ukuba umsebenzi wokubuyisela kwakhona kufuneka wenziwe ngomlinganiselo ophezulu wokujikeleza kwesantya sokuhamba, ubunzima obuthile kwibhithi engagqithiyo kwi-90N/mm (diameter), isantya sokujikeleza singadluli kwi-60 rpm apho ubambekile xa ukhubeka. kwi.
6 Ukuqhekezwa kancinci
1.Overusing izixhobo zokubonisa xa bit approch bottomhole.Ukuba i-WOB kunye ne-torque yonyuka, oko kubonisa ukuba bit have attived at bottomhole.Sebenzisa ngaphezu kwe-90N/mm, ubunzima -on = bit kunye ne-40to 60rpm ukuseka ipateni ye-bottomhole ubuncinane kwisiqingatha semitha.
I-2.Bit break-in igqityiwe kwaye kufuneka ilungelelaniswe i-RPM ukuze ifumane indibaniselwano yeparamitha yokugrumba eyona ilungileyo.
I-3.Uhlengahlengiso lweeparamitha ze-Drilling kufuneka zikhethwe ngaphakathi kwemida yeeparamitha ezicetyiswayo zibhekiselele kwiiparamitha ezicetyiswayo zokusebenzisa indlela yokuphucula.
