I-Mastering Rock Crossing nge-Advanced TCI Tricone Bit.

1. I-Rock Crossing Directional Drilling

①Izindlela zokumba iziqondiso zokuwela amadwala zifaka okulandelayo:

- Indlela Elula Yokwakha

- I-DITCH WITCH Indlela Yepayipi Lokubhobhoza Kabili Odonga

- I-Pneumatic noma iHydraulicI-Down-the-Hole HammerUmthelela kanye Ne-Rotary Directional Drilling

- Udaka Motor Directional Drilling Indlela

"Indlela yokumba i-motor motor directional" njengamanje iyindlela esetshenziswa kakhulu yokumba amadwala ngaphakathi nangaphandle. Ilungele izinsimbi zokubhoboza ezingenazintambo ezingamathani angama-25 nangaphezulu, ikakhulukazi izinsimbi ezinkulu ezingenazintambo.

Injini yodaka, eyaziwa nangokuthi i-screw drill, ivamise ukubhangqwa ne- “i-tricone drill bit” noma “Izingxenye zokugaya ze-PDC”, kanye nemishini yokuthola indawo enezintambo noma engenantambo. Ngesikhathi sokubhola okujwayelekile, induku yokubhoboza kanye nenjini zizungeza ndawonye ukuze kubholwe umugqa oqondile. Ukuze kubhojwe umugqa oqondile, indawo egobile yemoto iqondana nendawo yehora le-12 ekhonjiswe idivayisi yendawo. Kule modi, i-drill rod kanye ne-motor housing ihlala imile, ihlinzeka kuphela nge-counter-torque kanye ne-pump ye-torque. izungezisa i-drill bit, ithola ukubhola okuqondisayo.

I-engeli egobile yezinjini zodaka "izingcezu zokubhola ezivundlile” ngokuvamile isukela ku-1.5° ukuya ku-3°, futhi ukukhetha kuncike ekugobeni kwe-trajectory yepayipi eklanyelwe.

②Ukucushwa Kokuxhuma Kokubhola Okuqondiswe Kwezimo Zodaka:

- Okungenantambo: Induku yokubhoboza → Izindlu zezinsimbi → Imoto →Ama-Cones amathathu a-drill Bit

- Okunezintambo: Induku yokubhoboza → Ikhola yokubhoboza okungeyona uzibuthe → Indlu yezinsimbi → Ikholomu yokubhoboza okungeyona uzibuthe → Imoto →Ama-Cones amathathu a-drill Bit

 

2. I-Rock Crossing Reaming Drilling

Ngemva kokuqeda umgodi wokuhlola, ukuphinda kwenziwe kabusha ngokusekelwe kububanzi bepayipi.

2.1 Izinhlobo zama-Rock Reamers

①Kunezinhlobo ezimbili eziyinhloko zama-rock reamer:

- I-Fixed Tricone Rock Reamers: Lezi zisebenzisa izingxenye ze-tricone cutter ezivela ku-oilfield drill bits njengamathuluzi okusika, ashiselwe ku-shaft emaphakathi ne-base plate.

- Ama-Replaceable Roller Cutter Reamers: Lezi zihlaziyo zisebenzisa ama-roller cutters angashintshwa njengamathuluzi okusika, afakwa kubakaki noma amisiwe.

②Izinzuzo kanye nokubiI-Tricone Rock Bits

Izinzuzo:

- Umjikelezo omfushane wokukhiqiza.

- Ifanele amadayamitha ahlukahlukene (ikakhulukazi amancane kuya kwaphakathi), asukela ku-220mm kuya ku-1600mm, futhi avumelane nezimo ezihlukahlukene zokuma komhlaba.

- Uhlobo lwamazinyo olwenziwa ngendlela oyifisayo kanye nesakhiwo esithwalayo esisekelwe ku-rig kanye nezimo zokwakheka.

- Ukuqhekeka kwamatshe okusebenza kahle kwe-hydraulic kanye nokususwa kwemfucumfucu.

Ububi:

- Ukugqoka emuva kumsiki kunzima ukubhekana nokwakheka kwe-sandstone.

-Izingcezu zokuvula imboboingaguga ngemva kokulungiswa okuningana.

- Ukufaka ama-seal kusixhumi esibonakalayo sokusika kuthambekele ekuhlulekeni, nakuba izinto ezilwa nokuwisa zinciphisa ubungozi.

2.2 Izici zama-Roller Cutter Rock Reamers Ashintshayo zama-Medium-Small Rigs

①Lawa ma-remerers:

- Bhekana nezinkinga zokugqokwa kwangemuvadonsa izingcezu.

- Yiba nezindleko eziqhathanisekayo nezivaliwe ngerabhaIzingcezu ze-TCI trione, ukunciphisa izindleko zokusebenza.

- Qinisekisa ukusebenza okuphephile nokuthembekile ngokushintshwa okulula kwe-roller cutter.

2.3 Izici Ze-Roller Cutter Rock Reamer Eshintshayo Yezinsimbi Ezinkulu

①Izici ezibalulekile zifaka:

- Ifanele izinsimbi ezisindayo ezimpambanweni zamadwala ezinobubanzi obukhulu.

- Ifakwe imizimba engasetshenziswa kabusha futhiIzingcezu ze-HDD remer drillyakhelwe ukusetshenziswa isikhathi eside.

- Ama-Roller anamazinyo e-Ø19 carbide namaphrofayili enziwe ngokwezifiso (acacile nge-hard rock, i-conical yetshe elithambile).

 

3. Drilling Parameters

3.1 Ingcindezi Yokubhoboza

Ingcindezi yokubhoboza incike ezintweni ezinjengokuqina kwamadwala, ububanzi be-borehole, namandla ebhithi lokumba. Ingcindezi eyeqile kumathuluzi afana neI-PDC yokudonsa kancanekungaholela ekulimaleni kwemishini.

3.2 Isivinini Sokuzungeza

Ivamise ukunakekelwa ku-40 RPM noma ngaphansi, iqinisekisa ukusebenza okufanele kwamathuluzi afana nalaama-core barrel drill bits.

3.3 Ukugeleza Kodaka

Ukugeleza kodaka ngendlela efanele kubalulekile ekupholiseni nasekususeni imfucumfucu, ikakhulukazi uma usebenzisaI-API ejwayelekile yamabhithi e-triconeekwakhekeni kwe-sandstone.

 

4. Uhlelo Lokubuyisela Udaka

Izinhlelo ezididiyelwe zokuhlanza udaka zithuthukisa ukusebenza kahle kokumba. Zilondoloza izinsiza futhi zinciphise umthelela wendawo, zihambisana nezindlela zesimanje zokumba ezivame ukubandakanyaizingcezu zokuvula imbobonezindlela ezingenantambo.

Izinzuzo:

- Ibuyisa u-80-90% wodaka.

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

- Ixazulula izinselele zokulahla udaka futhi inciphise umthelela wemvelo.
