Revolutionizing Drilling: Yepamberi Bit Solutions.

Kuumbwa uye Chigadzirwa Series che API Standard Tricone Bits

1. Zvikamu zveTricone Rock Bits

Tricone drill bits inoumbwa nezvikamu zvishanu zvikuru: iyo drill bit body, gumbo, cones, bearing, uye nozzle. Kune akavharwa jet bits, anosanganisirawo lubrication uye muripo system.

2. Mutsara weTricone Drill Bits

① Diameter Series yeTricone Drill Bits

Domestic Drill Bits: Iyo dhayamita yakatevedzana inosanganisira gumi nemashanu saizi. Anowanzo shandiswa neKingdream 17 1/2", 12 1/4", 9 5/8",8 1/2", uye 3 7/8".

Inotorwa Drill Bits: Iyo dhayamita yemhando yakanyanya kuoma. Semuyenzaniso, mabhiti ekuboorera kubva kuUS-based Hughes Company anovhara 46 saizi kubva pa3 3/4" kusvika 26".

② Coding yeKingdream Oiri Tricone Bits

• Iyo modhi kodhi ine zvikamu zvina:
• Bit Diameter Code: Inomiririrwa mumainch, ingave yakazara kana chidimbu.
• Series Code: Inoratidza ekutanga maficha ekubereka uye chisimbiso chimiro cheMatatu Cones Drill Bit, akaiswa muzvikamu zvipfumbamwe.
• Classification Code: Nhamba nhatu apo:
• Nhamba yekutanga inoreva kutema chimiro uye kuumbwa kwakatevedzana.
• Nhamba yechipiri inoratidza giredhi rekugadzira.
• Dijiti yechitatu inoreva zvimiro zvebhiti.
• Zvimwe Zvimiro Zvimiro: Kune zvakakosha zvinodikanwa, zvigadziriso zvinocherechedzwa netsamba imwe kana anopfuura achitevera kodhi yemhando.

Muenzaniso:

8 1/2" HJT 537 G Drill Bit:

• 8 1/2": dhayamita yebhiti.
• HJT: Kutsvedza kubereka nesimbi chisimbiso uye yakakosha geji yekudzivirira.
• 537: Yakaderera kumanikidza simba, yakapfava kusvika pakati maumbirwo, TCI Tricone Bit.
• G: Gumbo rakasimbiswa.

3. Kusarudzwa kweTricone Bits

Sarudzo inoenderana nedata kubva kune akafanana maumbirwo mumatsime akavakidzana, mamiriro ekuumbwa, uye chaiyo tsime mamiriro. Funga nezve:

• Kugadzira kuoma uye abrasiveness.
• Kudzika kwechikamu chakaboorwa.
• Maumbirwo akakomberedzwa anoda anti-kutsauswa kubhowa.
• Kuchinjanisa maumbirwo akaoma uye akapfava.

4. Kutonga Tricone Bit Conditions Downhole

①Zvakajairwa Kushanda:

Nekuenderana kuumbwa lithology, kutenderera kwetafura kufamba kwakafanana, kumhanya kwechibhorani kunoramba kwakagadzikana, uye zviratidzo pamageji ekumanikidza zvakatsiga.

②Kutadza Kubereka:

Periodic stick-slip movement yetafura inotenderera, yakaderedzwa kumhanya kwechibooreso, uye ichichinja-chinja uremu-pa-bit kuverenga.

③Kukiya Koni:

Kuwedzera kutenderera, kutsvedza kwakakomba, uye kunetseka pakutenderedza tambo yekubooresa.

④Koni Yakadonha:

Yakakosha kutenderera mutoro wekuwedzera, kamwe kamwe kamuti-kutsvedza kufamba, uye kuderera kwechiyero chekupinda kana kusave nekuchera kufambira mberi.

⑤Mazino akasakara:

Yakareruka inotenderera mutoro, yakaderedzwa mwero wekupinda, uye yakatsiga yekumanikidza geji kuverenga.

⑥ Bit Balling:

Kuwedzera kutenderera kwemutoro, kuderedzwa kwechiyero chekupinda, uye yakakwira pombi pressure.

Diamond uyePDC Drag Bits

1. Mamiriro eDiamond Drill Bits

• Natural Diamond Drill Bits: Yakagadzirwa nesimbi muviri, matrix, nozzle, uye madhaimani zvimedu.
• PDC Cutter Drill Bits: Sanganisira muviri wesimbi, matrix, nozzle, uye polycrystalline diamond cutters.

2.PDC Drag Bits

①Profile Maumbirwo

PDC dhiza mabhiti ane maumbirwo matatu:

• Parabolic: Inokodzera mafomati akapfava, inopa yakakwira yekudhirowa kumhanya uye kugadzikana.
• Circular: Yakanakira kune yakaoma interlayers nekuda kweiyo concentrated hydraulics.
• Conical: Yakagadzirirwa kupinda kwakasimba uye kugadzikana mumabasa ekumhanya kwazvo.

②Bit Selection

Funga zvinhu zvakadai senzira yekuchera, rudzi rwekugadzira, uye zvigadziro zvekuchera paunenge uchisarudza PDC Drag Bit.

③ Mitemo Yekushandisa Yakakodzera

• Chengetedza kudzvanywa kwepombi pamusoro pe13 MPa.
• Dzivisa kudhumhana nezvinhu zvakaoma uye zvinongoerekana zvaitika panguva yekuchera.
• Geza pazasi petsime zvakanaka usati watanga maoparesheni.
• Shandisa optimal drilling parameters: uremu-pa-bit (30–60 KN), kumhanya kwekutenderera (117–217 RPM).

3. Coring Drill Bits

Coring drill bits akagadzirirwa annular kupwanya kubvisa rock cores. Mhando dzakajairika dzinosanganisira mabheti ekudhonza, tungsten carbide core bits, uye diamond core bits. Zvimiro zvakaita sesymmetry uye kupfeka kuramba kunovimbisa yakakwirira musimboti kudzoreredza mitengo.
