I-PDC Cutter ye-Diamond Bearing

Imboni esebenza kwezinye zezindawo ezinokhahlo emhlabeni ngezinye izikhathi idinga ukubiza izinto eziqinile zezingxenye ezigugile.

Faka idayimane lezimboni, elitholwe ngeminyaka yawo-1950s. Amadayimane okwenziwa angakwazi ukubekezelela ukuhwamuka, izinga lokushisa eliphezulu, nezindawo ezibolayo futhi amelane nemithwalo ephezulu.

Imboni kawoyela negesi kudala yamukela idayimane lezimboni le-polycrystalline diamond compact (PDC) drill bits, eyethulwa ngeminyaka yawo-1970s. Akuwona wonke amadayimane (PDC) afanayo. Ingase ibukeke ifana, imnyama phezulu futhi isiliva phansi, kodwa ayisebenzi ngendlela efanayo. Yonke indawo yokumba iletha izinselelo zayo ezihlukile. Yingakho onjiniyela bedinga ukuhlanganisa idayimane elifanele nezimo ezifanele zokumba.

Idayimane lisetshenziswa kancane njengempahla yobunjiniyela, futhi lingasetshenziswa kwezinye izinhlelo zokusebenza eziningi, njengokugqoka izingxenye ezinjengamavalvu nama-seal ezindaweni ezinokhahlo.

Eminyakeni engu-20 edlule, onjiniyela baye bafaka izinto ezisebenza kanzima emhlabeni ukuze bavikele ama-bearings emishini efana nezinjini zodaka, amaphampu kagesi angaphansi kwamanzi (ama-ESPs), izinjini zomoya, namathuluzi okubhola aqondisayo.

I-Polycrystalline Diamond radial bearings, ephinde yaqanjwa ngokuthi ama-PDC bearings, akhiwe ngochungechunge lwabasiki be-PDC abahlanganiswe (imvamisa ngokubhrashiswa) kumasongo okuthwala. Isethi ye-PDC ene-radial bearing ejwayelekile ihlanganisa iringi ezungezayo nemile. Lezi zindandatho ezimbili ziyaphikisana nendawo ye-PDC ngaphakathi kobubanzi bendandatho eyodwa ngokuthintana okuqondile nendawo ye-PDC kububanzi obungaphandle beringi yokukhwelana.

Ukusebenzisa ama-diamond bearings kuma-rotary steerable systems kungakhuphula ukuphila kwethuluzi, kwehlise usayizi wethuluzi futhi kunciphise ubunkimbinkimbi ngokukhipha izimpawu. Kumamotho odaka, kunciphisa ukugoba kancane kwethuluzi futhi kwandisa umthamo womthwalo.

Awukwazi ukulawula okusemanzini olwandle noma udaka lokumba, noma ngabe yisihlabathi, idwala, inhlabathi, ukungcola, noma insila, konke kudlula endaweni ephethe idayimane. Amabheringi edayimane angaphatha “kakhulu yonke into.”

Uma i-bearing yendabuko igqashuka, i-asidi, amanzi olwandle, nodaka lokumba kungangena, futhi ukuthwala kuzohluleka. I-diamond ephethe idayimane iphendulela ubuthakathaka be-bearing yendabuko ekhanda layo. Amabheringi edayimane embonini asebenzisa amanzi olwandle ukuze awagcine epholile, aphendule ubuthakathaka bube yisixazululo.

Uma unentshisekelo kubasiki be-PDC futhi ufuna ulwazi olwengeziwe kanye nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE I-IMEYILI ezansi nekhasi.
