Amasu we-7 we-Field ukwelula isikhathi sokuphila kwe-PDC Drill Bits

1. Faka isisindo kancane kancane ukugwema umthwalo womthelela  

Khishwa: nomaAma-pdc cutterzinzima kakhulu, zinokuphikiswa okuphansi komthelela. Isicelo esingesisisindo esingazelelwe singadala ukukhishwa kweshidi okuhlanganisiwe.  

Isixazululo:  

Sebenzisa isu elithi "Isinyathelo-ngesinyathelo ngesisindo" Isicelo: Qala ngo-30% wesisindo esinconyiwe ku-Bit (WOB), bese ukhuphuka ngo-20% njalo ngemizuzu eyi-10.  

Ukuqapha ukuguquguquka kwe-torque (ngamathuluzi we-MWD / LWD). Uma ukuguquguquka kudlula i-15%, ukunciphisa i-WOB.  

Isisekelo Sesayensi: Ama-coefficients we-thermal e-Thermallion engqimba yedayimane kanye ne-tungsten Carbide Substrate ahlukile, eholela kuma-microcracks endaweni yomthelela ngaphansi kwemithwalo yomthelela (i-SPE 168973 Study).  

 2. Lungiselela i-RPM ne-WOB Matchip  

ISIBONELELO: I-RPM ephezulu + ye-WOB ephansi ibangela ukusika kuka "ukugaya" kunokuba "i-shear" yokwakheka, ukusheshisa ukugqoka. I-RPM ephansi + i-WOB ephezulu ingakunxenxa ukudlidliza.  

Isixazululo:  

Bheka ifomula "elithile lamandla (se)"  

  Se = \ frac {wob \ times rpm} {rop \ times d ^ 2}  

  (ROP: Izinga lokungenile, D: Ububanzi obukhulu)  

  Lungisa i-RPM / WOB uma amanani e-SE akhuphuka ngokungajwayelekile.  

Ukwakheka okuthambile: I-RPM ephezulu + i-Medium-Low WOB (E.G., 60-80 RPM + 8-12 klbs).  

Ukwakheka kanzima: I-RPM ephansi + ephezulu (isb., 30-50 RPM + 15-20 klbs).  

 I-3  

ISIBONELELO: Okuqukethwe kwesihlabathi esiphakeme noma ukubonakala okuphansi ku-drive fluid kungadala:  

Ukuncishiswa kokuqongelela (ukubhoboza okuncane)→ Ukupholisa okunganele→ ukuwohloka okushisayo kwabasiki.  

Amanani aphezulu okugeleza aqeda umzimba omncane.  

Isixazululo:  

Gcina i-drive fluid fluid point (yp) ku-15-25 lb / 100ft² kokutholwa okusebenzayo kokuhamba.  

Sebenzisa ama-nano-scale bridging agents (e.g., Sio₂ Izinhlayiya) zokunciphisa ukubhomba okuncane (i-OTC 28921 idatha yokuhlola).  

Gada lokushisa lokushisa; Uma kudlula i-150°C, khuphula izinga lokugeleza noma engeza izithambisi zengcindezi enkulu.  

 4. Gwema ukumba okuphoqelelwe ekwakhekeni okuhlanganisiwe  

QAPHELA:Ama-PDC BitsNgokushintshana kwezakhiwo ezinzima / ezithambile (isb. 

Isixazululo:  

Hlaziya ukusulwa kwezingodo kahle kusengaphambili ukukhomba izindawo ezihlanganisiwe.  

Yehlisa i-rop ngo-20% bese ushintshela kumodi ye-WOB njalo uma ukuguquguquka kwe-torque kwenzeka njalo.  

Sebenzisa ama-hybrid bit design (e.g., ama-backup cutter) ukuze athuthukise umthelela othuthukisiwe.  

 5. Yenza uhambo olufushane ukuze uhlanze umthombo we-Wellbore  

ISINQUMO: I-Cuttings Build ezansi kuholela ekunciphiseni kabusha, ukunciphisa ukusebenza kahle nokusheshisa ukugqokwa kwegeji.  

Isixazululo:  

Yenza uhambo olufushane (esicathulweni esidonsayo) wonke amamitha ayi-150-200 avuthiwe.  

Ukujikeleza uketshezi olungenayo okungenani imijikelezo emi-2 ngaphambi kokukhipha, uqinisekise ukuhlanzeka kwe-ansurar (qinisekisa ngokuqapha umbhede).  

 6  

ISIBONELELO: Emafoshini elibi nge-> 40% Quartz okuqukethwe, izingcezu ze-PDC zingaba "skate" (zijikeleze ngaphandle kokungena ngaphakathi).  

40% Quartz okuqukethwe, izingcezu ze-PDC zingaba "skate" (zijikeleze ngaphandle kokungena ngaphakathi).  

Isixazululo:  Shintshela ku-Non-PlanAma-PDC Bits

(e.g.  

Faka uketshezi olususelwa ku-busing olususelwa ku-microfractures okwesikhashana futhi uthuthukise ukususwa kwe-cuttings.  

 Uma i-skatist iqhubeka ne> imizuzu engama-30, khipha bese uyifaka esikhundleni se-roller cone noma i-Integnated bit.  

imizuzu engama-30, khipha bese uyifaka esikhundleni se-roller cone noma i-Integnated bit.  

7. Landela izinqubo ezifanele zokuhamba ukuvikela ukulimala kwemishini  

ISIBONELELO: Ukushayisana nokukhipha izindonga noma izindonga ze-Wellbore kungadala ukuchitheka kwedayimane.  °Isixazululo:  

Khawulela isivinini esikhulu ku-

10

/ 30m.  – Sebenzisa Abavikeli Ababavikeli (isb., Abavikeli bentambo yerabha) ngesikhathi sokuhamba nokugcinwa.  Zungeleza imizuzu eyi-10 ngaphambi kokufika ezansi ukuze ususe ukusika okulungisiwe.

Umlingani wakho wezobuchwepheshe obugcwele

Ama-PDC Bits

 Ukumba okusebenzayo kuqala ngokuxhaswa kwethu kwesayensi! Asinikeli kuphela ukuhlinzeka nge-PDC bits ephezulu ye-PDC kepha futhi sinikeza iphakethe lezobuchwepheshe elikhethekile lezobuchwepheshe:

 1. I-Intelligent Parameter Manual: Iqukethe ama-matric weWob / RPM aqondanise ama-matric wezimo zokusebenza ezi-7, okwenza ukuthi ukhiye kumapharamitha wokumba okufanele ngemizuzwana engama-30.
