Mastering Rock Crossing neAdvanced TCI Tricone Bit.

1. Rock Crossing Directional Drilling

①Maitiro ekuchera nzira dzekuyambuka dombo dzinosanganisira dzinotevera:

- Nyore Kuvaka Nzira

- DITCH WITCH Double-Wall Drill Pipe Method

- Pneumatic kana HydraulicDown-the-Hole HammerImpact uye Rotary Directional Drilling

- Mud Motor Directional Drilling Method

Iyo "mud motor directional drilling method" parizvino ndiyo inonyanya kushandiswa nzira yekudhirowa kwedombo mukati nekunze. Yakakodzera kuchera isina trenchless matani makumi maviri neshanu uye pamusoro, kunyanya makuru asina trenchless rigs.

Iyo mota yedhaka, inozivikanwawo se screw drill, inowanzo batanidzwa ne "chidimbu chetricone drill” kana kuti “PDC drill bits”, pamwe newaya kana mawaya ekutsvaga michina.Panguva yekuchera yakajairika, chibooreso nemota zvinotenderera pamwe chete kuti zviboore mutsara wakatwasuka.Kudhiraivha kwakananga, imba yakakotama yemotor inopindirana nenzvimbo yegumi nembiri inoratidzirwa nechishandiso chekutsvaga. Mune iyi modhi, chibooreso nemotikari yedzimba zvinoramba zvakamira, zvichipa chete chidhiraivho, pombi yemagetsi. inotenderedza chibooreso, ichiwana kudhirowa kwakananga.

Kona yakakombama yemamota emadhaka e”horizontal drilling bits” kazhinji inotangira pa1.5° kusvika pa3°, uye sarudzo inotsamira pakukombama kwepombi yakagadzirwa.

②Magadzirirwo ekubatanidza eMadhaka Motor Directional Drilling:

- Wireless: Drill tsvimbo → Imba yemidziyo → Motokari →Three Cones drill Bit

- Wired: Drill tsvimbo → Non-magnetic drill collar → Imba yezviridzwa → Isiri-magnetic drill collar → Mota →Three Cones drill Bit

 

2. Rock Crossing Reaming Drilling

Mushure mekupedza gomba rekutyaira, reming inoitwa zvichienderana nedhayamita yepombi.

2.1 Mhando dzeRock Reamers

①Kune mhando mbiri huru dzedombo reamers:

- Yakagadziriswa Tricone Rock Reamers: Aya anoshandisa zvikamu zvetricone cutter kubva kuoilfield drill bits semidziyo yekucheka, yakasungirirwa kune reamer yepakati shaft uye base plate.

- Replaceable Roller Cutter Reamers: Aya mareji anoshandisa anogona kutsiva roller cutters sematurusi ekucheka, anoiswa angave pamabhuraki kana mukumiswa.

②Zvakanakira uye Zvakaipa zveTricone Rock Bits

Zvakanakira:

- Short kugadzira kutenderera.

- Inokodzera madhayamita akasiyana (kunyanya madiki kusvika pakati), kubva pa220mm kusvika 1600mm, uye inochinjika kune akasiyana geological maumbirwo.

- Customizable zino mhando uye inobereka chimiro chakavakirwa rig uye maumbirwo mamiriro.

-Inoshanda hydraulic rock breaking uye kubvisa tsvina.

Zvakaipa:

-Kupfeka kwemusana pane yekucheka kwakaoma kugadzirisa mune sandstone formations.

-Hole opener bitsinogona kupera mushure mekugadzirisa kakawanda.

-Kutakura zvisimbiso pacheki interface kunowanzotadza, asi anti-kudonha zvishandiso zvinoderedza njodzi.

2.2 Zvimiro zveReplaceable Roller Cutter Rock Reamers yeMedium-Small Rigs

①Magadzirirwo aya:

- Gadzirisa nyaya dzekumashure dzekupfeka dzedhonza zvimedu.

-Iva nemutengo unofananidzwa nerabha-yakavharwaTCI trione bits, kuderedza mari yekushandisa.

- Ita shuwa mashandiro akachengeteka uye akavimbika ane nyore roller cutter kutsiva.

2.3 Zvimiro zveReplaceable Roller Cutter Rock Reamers kune Makuru Rigs

①Zvinhu zvakakosha zvinosanganisira:

-Inokodzera inorema-basa rigs muhombe-diameter yedombo kuyambuka.

- Yakashongedzerwa nemiviri inogona kushandiswa zvakare uyeHDD reamer drill bitsyakagadzirirwa kushandiswa kwenguva refu.

-Roller ane Ø19 carbide mazino uye customizable profiles (yakashata yedombo rakaoma, conical yedombo rakapfava).

 

3. Drilling Parameters

3.1 Drilling Pressure

Drilling pressure inoenderana nezvinhu zvakaita sekuoma kwedombo, borehole dhayamita, uye kusimba kwechibhorani. Kunyanya kudzvanywa pamidziyo yakaita sePDC dhonza zvishomazvinogona kutungamirira kukukuvara kwemidziyo.

3.2 Kutenderera Kumhanya

Inowanzo chengetwa pa40 RPM kana pazasi, kuve nechokwadi chekuita kwakaringana kwezvishandiso zvakaitacore barrel drill bits.

3.3 Kuyerera kwedhaka

Kuyerera kwemadhaka kwakakodzera kwakakosha pakutonhodza uye kubvisa tsvina, kunyanya kana uchishandisaAPI yakajairwa trione bitsmune sandstone formations.

 

4. Mud Recovery System

Masisitimu akabatanidzwa ekuchenesa madhaka anovandudza kuchera. Vanochengetedza zviwanikwa uye kuderedza kukanganiswa kwezvakatipoteredza, kuenderana nemaitiro emazuva ano ekuchera ayo anowanzo kusanganisiraburi rekuvhura mabhitiuye trenchless matekiniki.

Zvakanakira:

- Inodzorera 80-90% yematope.

- Inoponesa 40-50% ye bentonite.

- Inogadzirisa matambudziko ekurasa madhaka uye inoderedza kukanganisa kwezvakatipoteredza.
