I-Tri-Cone Drill Bit: Imininingwane Yohlelo Lokusebenza

1) Isakhiwo esiyisisekelo se-aama-tricone drill bits. Umzimba we-drill bit: Kunezingcezu ezintathu zamazinyo ezihlanganiswa futhi zishiselwe ndawonye, ​​futhi kunezintambo ezixhumayo engxenyeni engenhla. Igiya: umzimba wensimbi omise okwekhoni owakhiwe umzimba wegiya namazinyo. Amazinyo ahlukaniswe abe izinhlobo ezimbili: amazinyo agayiwe futhi afaka amazinyo, ama-bearings kanye nemibhobho yemishini yokuvala uwoyela yokugcina uwoyela.

2) Isimiso sokusebenza sebhithi ye-roller cone Lapho i-i-roller cone kancaneisebenza ngaphansi komthombo, i-drill bit yonke izungeza i-axis ye-drill bit, ebizwa ngokuthi i-revolution, futhi ama-cones amathathu agingqa phansi komthombo ngokwezimbazo zawo, okuthiwa ukuzungeza. Ingcindezi yokumba ebekezelelwa yi-drill bit isebenza edwaleni ngamazinyo, okwenza idwala liphuke (umphumela wokuchoboza). Phakathi nenqubo yokugoqa, i-cone ithintana ngokuhlukile phansi komthombo ngamazinyo angashadile namazinyo amabili, futhi isikhundla sesikhungo se-cone siyashintshashintsha, okwenza ukuthi i-drill bit idlidlize ngobude. Lokhu kudlidliza kwe-longitudinal kubangela ukuthi intambo yokubhoboza icindezele futhi yelule ngokuqhubekayo. Intambo yokubhoboza ephansi iguqula lokhu kushintsha ngezikhathi ezithile amandla okuguquguquka okunwebekayo abe amandla okuthonya ekwakhekeni ngamazinyo ukuze aphule idwala. Lo mthelela kanye nomphumela wokuchoboza kuyindlela eyinhloko yokuthi i-roller cone drill bit iphule amadwala.

Ngaphezu kokuthinta nokuchoboza idwala ngaphansi komthombo, i-roller cone bit iphinde ikhiqize imiphumela yokugunda edwaleni elingaphansi komthombo. Ngenkathi i-cone iginqika phansi komthombo, iphinde ibangele ukuthi amazinyo ashelele ngaphansi komthombo. Ukushelela kwamazinyo kudala umphumela wokugunda edwaleni elingaphansi komthombo, kunwaya phansi komthombo njenge-scraper bit. Ukushibilika kwamazinyo kudalwa ikakhulukazi ngaphezulu kwe-over-top, i-axiliary cone kanye nokuhlelwa kokushintshashintsha kwesondo legiya. Ukuhlelwa ngaphezulu kwekhoni yekhoni kubangela ukushelela kuhlangothi lwe-tangential, futhi ukuhlelwa kokushintsha kwekhoni kubangela ukushelela ku-axial direction. Ngokuvamile,ukubhoboza izingcezungoba ukubhoboza ukwakheka okuthambile kuya kokuqina okuphakathi kuklanywe nge-over-top, ikhoni ehlanganisiwe kanye nama-shaft aguqukayo; ama-drill bits okwakhiwa okuphakathi-okuqinile kuya kokuqina aklanywe ngezigaxa ezingaphezulu nezihlanganisiwe; ama-drill bits okubhoboza aqine ngokwedlulele futhi ama-abrasive aklanywe ngamakhoni angaphezulu nahlanganisiwe. Ama-drill bits ngokuvamile asebenzisa amakhoni ekhoni eyodwa, angadubuli kakhulu noma anyakazise i-eksisi.

3) Ukuhlelwa Nokukhethwa Kwama-roller Bits Baningi abakhiqizi be-roller bits, futhi laba bakhiqizi be-drill bit bahlinzeka ngama-drill bits ezinhlobo ezahlukene nezakhiwo. Ukuze kube lula ukukhetha nokusebenzisa izingcezu ze-roller cone, i-International Institute of Drilling Contractors (IADC) ithuthukise izinga elihlanganisiwe lokuhlukanisa kanye nendlela yezinombolo zamabhithi ekhoni yamarola emhlabeni jikelele. I-IADC ibeka ukuthi uhlobo ngalunye lwe-drill bit lumelwe inombolo enezinombolo ezintathu, futhi incazelo yenombolo ngayinye imi kanje:

• Idijithi yokuqala ibonisa uhlobo lwezinyo kanye nokwakheka okufanele ukubhoboza: 1- izinyo lokugaya, ukwakheka okuthambile; 2- izinyo lokugaya, ukwakheka okuqinile okuphakathi kuya kokuphakathi; 3- izinyo lokugaya, ukwakheka okuqinile, okulimazayo noma okulimazayo; 4 - okusele; 5-Izinyo, ukwakheka okuthambile kuya kokuphakathi; 6-Izinyo, ukwakheka okuqinile okuphakathi; 7-Amazinyo, aqinile, abrasive noma ukwakheka kwe-semi-abrasive; 8-Azinyo, aqine ngokwedlulele, akheke ngendlela elumayo.
• Idijithi yesibili ikhombisa ukuthi ukwakheka okubhoboshiwe kuhlukaniswe ngamamaki amane obunzima: 1, 2, 3, kanye no-4.
• Idijithi yesithathu ikhombisa izici zesakhiwo sebhithi yokubhoboza: 1- I-rolling bearing engavaliwe; 2- Umugqa wangaphandle wamazinyo omise okwe-T ukuze uvikeleke ububanzi; 3- Faka amazinyo ukuze uthole ukuvikela ububanzi kububanzi begeji; 4- Ukugoqa okuvalwe uphawu; 5- Izinsimbi ezigoqayo ezivaliwe kububanzi begeji Kukhona okufakwayo namageji; 6- ama-sliding bearings avaliwe; 7- ama-sliding bearings avaliwe anezinsimbi nezikali kugeji; 8- izingcezu zokuphambuka komthombo; 9 - abanye.

Izici nezinzuzo zama-roller cone drill bits:

• 1. Ukuphuka kwedwala okunemiphumela ekabili yokuthinta nokugunda, kokubili umthelela wamazinyo nokugunda okubangelwa ukushelela, okuholela ekusebenzeni kahle kokuphuka kwamadwala.
• 2. Iyakwazi ukuzivumelanisa nezimo ezihlukahlukene ze-strata futhi ifanele ukubhoboza kuzo zonke izigaba.
• 3. I-drill bit inomphumela omuhle wokuzihlanza futhi akulula ukuthi ibe nodaka.
• 4. Izindleko ze-Drill bit ziphansi.
