7 manhamba emunda kuti uwedzere hupenyu hwePDC Drill Bits

1. Shandisa uremu zvishoma nezvishoma kudzivirira kukanganisa  

Nyaya: KunyangwePDC Cuttervanonyanya kuoma, vane vakaderera kukanganisa. Kamwe kamwe uremu application kunogona kukonzera kuumbwa kwero pipping.  

Solution:  

Shandisa "nhanho-nhanho uremu application" zano: trategy: trategy  

Monitor Torque Fletuations (kuburikidza neMWD / LWD Zvishandiso). Kana kuchinjika kuchikwira 15%, kuderedza wob.  

Sainzi Sosi: Iyo inowedzera yekuwedzera coefficients yeDiamond Layer uye tungsten carbide subfer  

 2. Optimize RPM uye WOB inofananidza  

Chinyorwa: Yakakwira RPM + Won Wander Inokonzera Vanodzikisira Kuti "Kugaya" Pane "Shear" Kuumbwa, Kuumbwa, Kugadziriswa. Low rpm + Yakakwira WOB inogona kuunza tsvimbo-kutsvedza vibration.  

Solution:  

Tarisa uone "Simba Rakajeka (se)" formula:  

  Se = \ FRAC {WOB 4. Times rpm} {rop \ times d ^ 2}  

  (ROP: Rate yePenetiration, D: Bit Diameter)  

  GADZIRA RPM / WOB kana SE ZVINOKOSHA ZVINOGONESA ZVAKAWANDA.  

Zvimiro zvinyoro-nyoro: High Rpm + Pakati WOB (i.e., 60-80 RPM + 8-12 klbs).  

Zvigadzirwa zvakaoma: Low RPM + Yakakwira WOB (i.e., 30-50 RPM + 15-20 klbs).  

 3. Kudzora kuchera zvinhu zvakadzika zvekudzivirira kubhuroka & kurwisa kukuvara  

Chinyorwa: Yakakwira jecha Zvinyorwa kana yakaderera viscosity mukuchera mvura inogona kukonzera:  

Cuttings kuunganidzwa (zvishoma kuba)→ kusakwanira kutonhora→ kudzikisira kwekuvaraidza kwevakacheka.  

Yakakwira inoyerera mitengo inobvisa zvishoma muviri.  

Solution:  

Chengetedza kufambisa fluid goho poder (YP) na15-25 lb / 100ft² yekuzvitakura zvinobudirira.  

Shandisa Nano-Scald to Bridging Agents (i.e., Sio₂ zvidimbu) kuti uderedze zvishoma kuba (OTC 28921 data rekuyedza).  

Tarisa kudziya kwekunze; Kana uchikwira 1500°C, Wedzera kuyerera kuyerera kana kuwedzera zvakanyanyisa-kumanikidza lubriants.

Chinyorwa:PDC BITSMukuzadziswa zvakaoma / zvinyoro-nyoro (i.e., sand-shale kutevedzana) zvinowanzoitika kune vanotevera viji, zvichikonzera kupfekedza kupfeka kana kupunzika cutters. 

Solution:  

Ongorora kudzikisira zvakanaka matanda pamberi pekuzivisa nzvimbo dzakabatanidzwa.  

Kuderedza rop ne20% uye switch kune inogara ichipfuudza maitiro kana torque kuchinjika kazhinji kazhinji.  

Shandisa hybrid bit bit dhizaini (i.e., backup cutters) yekuvandudza kukanganisa kukanganisa  

 5. Ita nzendo pfupi kuti uchenese zvakanaka  

Chinyorwa: Cutings Kuvaka pazasi kunotungamira kuongorora zvakare, kuderedza kushanda zvakanaka uye kukurumidza kupfeka geji.  

Solution:  

Bata rwendo rwepfupi (kune shangu yecasing) yega yega 150-200 metres yakadhirowa.  

Kutenderera kuchera mvura kune kanenge 2 cycle nguva usati wadonhedza kunze, kuona kuchena kweAntular  

 6. Ziva uye kuderedza "zvishoma kutungamira  

Nyaya: MuBrittle Fordations ne> 40% Quartz Zvemukati, PDC Bits May "Skate" (Tenderedza pasina penethe).  

40% Quartz Zvemukati, PDC Bits May "Skate" (Tenderedza pasina penethe).  

Solution:  Chinja kune isiri-planarPDC BITS

.  

Inisa siltirate-based kucherwa kwemvura kuti isimbe yemasuru microfractures uye kuvandudza kudzurwa kwekubviswa.  

 Kana skating ichiramba ichingopera kwe> makumi matatu maminitsi, dhonza kunze uye kutsiva ne roller cone kana kuti isingaonekwe zvishoma.  

makumi matatu maminitsi, dhonza kunze uye kutsiva ne roller cone kana kuti isingaonekwe zvishoma.  

7. Tevedza maitiro akakodzera ekurongedza kuti udzivise kukuvadzwa kwekukuvara  

Nyaya: Kugadziriswa neClasing kana Wellbore Masvingo kunogona kukonzeresa dhaimani dhayamende shuwa.  °Solution:  

Gumisa kumhanya kumhanya kune

10

/ 30m.  – Shandisa bit bit vadziviriri (i.e., rabber tambo dzinodzivirira) panguva yekufambisa uye kuchengetedza.  Carticlate kwemaminitsi gumi usati wasvika pasi kuti ubvise akachekwa.
