Iindlela ezisi-7 zentsimi yokwandisa ixesha lobomi be-PDC Drill Bits

1. Faka ubunzima ngokuthe ngcembe ukuthintela umthwalo wefuthe  

Umcimbi: NangonaI-pdc cutterszinzima kakhulu, zinokungaxhathisi bempembelelo. Isicelo sesisindo ngesiquphe sinokubangela iphepha lokudibanisa.  

Isisombululo:  

Sebenzisa isicwangciso-qhinga sendlela "yenqanaba lenyathelo lenqanaba lesiqhelo: Qalisa nge-30% yobunzima obucetyiswayo kwi-bit (WOB), emva koko unyuke nge-20% qho kwimizuzu eli-10 kude kube selunxwemeni lwe-WOB.  

Ukubeka iliso kuguquko lweTorth (nge-MWD / izixhobo). Ukuba ukuguquguquka kuyadlula i-15%, ukunciphisa i-WOB.  

Isizathu seSayensi: Ukwanda kweSermal Coefficents yeDayimond kunye ne-tungsten carbide ye-sungster kunye ne-rungster fikere, ekhokelela kwii-microscres, ekhokelela kwii-microscres kwi-interfaces phantsi kwemithwalo yempembelelo (Speen 168973 uphononongo).  

 2. Yandisa i-RPM kunye ne-WOB  

Umcimbi: I-RPM ephezulu + ye-WOB ye-WOB ibangela ukuba i-cutters iye "grind" kunokuba "i-shear" i-fomution, ukuqaphela. I-RPM ephantsi + ye-WE ephezulu ye-vibration ye-slick.  

Isisombululo:  

Jonga "amandla athile (se)" ifomula:  

  Se = \ frac {ye-WOB \ Times RPM} {rop \ amaxesha d ^ 2}  

  (ROP: Ixabiso lokungena, D: I-bit ye-bit)  

  Lungisa i-RPM / WOB ukuba i-seas inyuka ngendlela engaqhelekanga.  

Imo ethambileyo: I-RPM ephezulu + ye-Wied-i-WOB WOB (E.G., 60-80 RPM + 8-12 KLBs).  

IIMPAWU ZOKUGQIBELA  

 I-3. Ukulawulwa kweepropathi ezingenayo  

Umcimbi: Umxholo ophezulu weSanti okanye i-viscofity esezantsi kwi-Sleid enokubangela:  

Ukuqokelelwa kokusika (ibhola encinci)→ ukuphola ngokwaneleyo→ ukonakaliswa kwe-shirmal.  

Ireyithi ephezulu yokuhamba ikhupha umzimba omncinci.  

Isisombululo:  

Gcina inqaku le-fluid ye-fluid² Ukuhamba ngokukuko okusebenzayo.  

Sebenzisa i-Nano-Agers Agents Bridheng (E.G., Sio₂ amasuntswana) ukunciphisa ukubekwa ibhola (i-OTC 28921 yedatha yovavanyo).  

Ukubeka iliso kwiqondo lokushisa; Ukuba ngaphezulu kwe-150°C, nyusa umgangatho wokuhamba okanye ukongeza i-coubricants egqithisileyo.  

 4. Kulumkele ukuqhuba ngokunyanzeliswa  

Khupha:I-PDC BitsNgokutshintsha ubunzima obuqinileyo / oqinileyo (i.G., ulandelelwano lwe-Sand-shale) bathambekele kwiindawo eziguqukayo ze-Lateral, kubangela i-gage gaure okanye i-Gauge Dish okanye i-Diageters. 

Isisombululo:  

Cazulula iindawo zokungena kakuhle ngaphambi kwexesha lokuchonga imimandla edibeneyo.  

Ukunciphisa i-ROP nge-20% kwaye ukutshintshela kwimowudi ye-WOB ye-Torque ukuba i-Torque Flweions isebenza rhoqo.  

Sebenzisa uyilo lwe-hybrid bit  

 5. Yenza uhambo olufutshane lokucoca iqula  

Umcimbi: Ukusika iindawo zokusika ezantsi kukhokelela ekunciphiseni, ukunciphisa ukusebenza ngokukuko kunye nokukhawulezisa ukunxiba.  

Isisombululo:  

Yenza uhambo olufutshane (ukuya kwisihlangu esisekiweyo) rhoqo kwiimitha ezili-150-200.  

Ukujikeleza ukuntywila kwamanzi kangangemijikelo emi-2 ubuncinci ngaphambi kokutsala, ukuqinisekisa ukucoceka kwaselwandle (qinisekisa ngeliso lokuhlambela).  

 I-6. Chonga kwaye unciphise i "typeling"  

Umcimbi: Kwi-Brotletset ye-Brittle Mering I-Partz Umxholo, I-PDC Bits inokuba "ukutsiba" (Jikeleza "(jikeleza).  

Isisombululo:  

Tshintshela kwi-non-bhankiI-PDC Bits.  

I-Laty  

Ukuba ukukhwela ukuqhubeka> Imizuzu engama-30, khupha kwaye ubeke endaweni ye-roller cone okanye incinci.  

  Imizuzu engama-30, khupha kwaye ubeke endaweni ye-roller cone okanye incinci.  

7. Landela iinkqubo ezifanelekileyo zokuhamba ukuthintela ukonakala koomatshini  

Umcimbi: Ukungqubana nge-cheng okanye iindonga zequladi kunokubangela idayimani yedayimane.  

Isisombululo:  °Umda wokuhambahamba kwi-0.5 m / s, ngakumbi kwi-Godlegs> 10

10

/ I-30m.  

Sebenzisa i-bit therties (E.G., i-TABIR TARD APRORDS) ngexesha loThutho kunye nokugcinwa.  – Cima imizuzu eli-10 ngaphambi kokuba ufike ezantsi ukuze ususe ukusikwa.  I-Drillmore incinci izixhobo

Iqabane lakho elipheleleyo lezobuchwephesha

I-PDC Bits

Ukutsiba okufanelekileyo okuqala ngenkxaso yethu yesayensi! Asiboneleli kuphela i-PDC yokusebenza kwi-PDC okanye ikwabonelela ngephakheji yezobuchwephesha ekhethekileyo:

 1. Incwadana yemigaqo ye-parameter ye-radimeter: iqulethe i-WOB / i-RPM ehambelana nematriki yeemeko ezisi-7, ikwazise ukuba uvale kwiiparamitha zokuqhuba ngokugqibeleleyo kwimizuzwana engama-30.

 2. Ithala leencwadi lesiCwangciso seSicombululo
