I-Mastering Rock Crossing kunye ne-Advanced TCI Tricone Bit.

1. Rock Crossing Directional Drilling

①Iindlela zokomba zokuwela amatye zibandakanya oku kulandelayo:

- Indlela elula yokwakha

- IGQWALA LEGQIRHA Indlela yoMbhobho yoMbhobho wokuBomba kabini

-I-Pneumatic okanye i-HydraulicIhamile ephantsi komngxumaImpembelelo kunye neRotary Directional Drilling

- Indlela yoKwemba iMoto yodaka

“Indlela yokomba yemoto yodaka” ngoku yeyona ndlela ixhaphakileyo yokugrumba ilitye ngaphakathi nangaphandle. Ilungele izixhobo zokomba ezingenamijelo eziziitoni ezingama-25 nangaphezulu, ngakumbi iirigi ezinkulu ezingenamijelo.

Injini yodaka, ekwaziwa njenge-screw drill, idla ngokudityaniswa ne “i-tricone drill bit” okanye “PDC drill bits", kunye nezixhobo zokubeka iintambo okanye ezingenazingcingo. Ngexesha lokomba oluqhelekileyo, intonga ye-drill kunye ne-motor zijikeleza kunye ukuze kuqhutywe umgca othe tye. Ukuqhuba umkhombandlela, indlu egobileyo ye-motor ihambelana nendawo ye-12 yentsimbi ebonakaliswe sisixhobo sokubeka. Kule modi, intonga ye-drill kunye ne-motor housing ihlala imile, inika kuphela i-motor ye-counter-torque kunye ne-motor ye-motor. ujikelezisa i-drill bit, ukuphumeza ukubhola okubhekiselele.

I-engile egobileyo yeenjini zodaka "amasuntswana okomba othe tyaba” ngokuqhelekileyo ukusuka kwi-1.5 ° ukuya kwi-3 °, kwaye ukhetho luxhomekeke kwi-curvature ye-trajectory yombhobho oyiliweyo.

②Ulungelelwaniso loQhagamshelwano loKugrunjwa kweMoto yodaka:

-Okungenazingcingo: Intonga yoKweba → Indlu yesixhobo → IMoto →Iicones eziNtathu zobhora iBit

-Enezintambo: Intonga yokomba → Ikhola yobhola engeyiyo eyemagnetic → Indlu yesixhobo → Ikhola yobhola engenamagnetic → Imoto →Iicones eziNtathu zobhora iBit

 

2. Rock Crossing Reaming Drilling

Emva kokugqiba umngxuma wokulingwa, ukubuyiswa kwakhona kwenziwa ngokusekelwe kububanzi bombhobho.

2.1 Iindidi zeeNgxobhozo zamatye

①Zimbini iindidi eziphambili zezixhobo zamatye:

- Fixed Tricone Rock Reamers: Ezi zisebenzisa i-tricone cutter segment ukusuka kwi-oilfield drill bits njengezixhobo zokusika, ezidityanisiweyo kwi-shaft ephakathi ye-reamer kunye ne-base plate.

-Replaceable Roller Cutter Reamers: Ezi reamers zisebenzisa i-roller cutters ezithatha indawo njengezixhobo zokusika, ezifakelwa mhlawumbi kwizibiyeli okanye zinqunyanyiswe.

②Izinto eziluncedo kunye nezingeloncedoTricone Rock Bits

Izinto eziluncedo:

- Umjikelo omfutshane wokuvelisa.

- Ifanelekile kwiidayamitha ezahlukeneyo (ingakumbi ezincinci ukuya eziphakathi), ukusuka kwi-220mm ukuya kwi-1600mm, kwaye zilungelelaniswe kwiindlela ezahlukeneyo zejoloji.

- Uhlobo lwezinyo olwenziwe ngokwezifiso kunye nesakhiwo sokuthwala ngokusekelwe kwi-rig kunye neemeko zokubunjwa.

- Ukuqhekezwa kwamatye okusebenza ngoxinzelelo lwehydraulic kunye nokususwa kobutyobo.

Izinto ezingeloncedo:

- Ukunxiba ngasemva kwi-cutter kunzima ukujongana neefom zesanti.

-Amasuntswana okuvula umngxumainokuguga emva kolungiso oluninzi.

-Ukuthwala amatywina kwi-interface ye-cutter kuthanda ukusilela, nangona izixhobo ezichasene nokuwisa zinciphisa umngcipheko.

2.2 Iimpawu zeRoller Cutter Rock Reaamers eziTshintshwayo kwiiRigs eziPhakathi neziNcinane

①Ezi zihlaziyo:

- Ukujongana nemiba yokunxiba ngasemvaamasuntswana otsalo.

- Yiba nexabiso elithelekisekayo nerabha etywiniweyoI-TCI trione bits, ukunciphisa iindleko zokusebenza.

-Ukuqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo ngokutshintshwa kwe-roller cutter elula.

2.3 Iimpawu zeRoller Cutter Rock Reaamers eziTshintshwayo kwiiRigs ezinkulu

① Iimpawu eziphambili ziquka:

- Ifanele iirigi ezinobunzima obukhulu kwiindawo zokunqumla amatye ezinobubanzi obukhulu.

- Uxhotyiswe ngemizimba enokusetyenziswa kwakhona kunyeHDD reamer drill amasuntswanayenzelwe ukusetyenziswa ixesha elide.

-Iirola ezinamazinyo e-Ø19 e-carbide kunye neeprofayili ezinokwenziwa ngokwezifiso (i-blunt for rock hard, conical for soft rock).

 

3. IiParameters zoKwemba

3.1 Uxinzelelo loKwemba

Uxinzelelo lokugrumba luxhomekeke kwizinto ezifana nobulukhuni bamatye, i-borehole idayamitha, kunye nokomelela kwentwana yokomba. Uxinzelelo olugqithisileyo kwizixhobo ezifana nePDC tsala bitkunokukhokelela kumonakalo wezixhobo.

3.2 Isantya sokujikeleza

Ngokuqhelekileyo igcinwe kwi-40 RPM okanye ngaphantsi, iqinisekisa ukusebenza okufanelekileyo kwezixhobo ezifanaamasuntswana okomba umphanda.

3.3 UkuMpompoza kodaka

Ukuhamba ngodaka okufanelekileyo kubalulekile ekupholiseni nasekususeni inkunkuma, ngakumbi xa usebenzisaAPI amasuntswana etricone esemgangathwenikwiindlela zesanti.

 

4. Inkqubo yokubuyisela udaka

Iinkqubo ezidibeneyo zokucocwa kodaka ziphucula ukusebenza kakuhle kokomba. Zigcina izixhobo kwaye zinciphisa impembelelo yokusingqongileyo, zihambelana neendlela zanamhlanje zokomba ezihlala zibandakanyaamasuntswana okuvula umngxumakunye nobuchule obungenamsele.

Izinto eziluncedo:

- Ibuyisela i-80-90% yodaka.

- Ugcina i-40-50% ye-bentonite.

- Usombulula imingeni yokulahlwa kodaka kwaye unciphise impembelelo yendalo.
