Tri-Cone Drill Bit: Application Insights

1) Chimiro chekutanga che azvidimbu zvetricone drill. Chibooreso chemuviri: Kune zvidimbu zvitatu zvemazino zvinounganidzwa uye kubatanidzwa pamwe chete, uye kune tambo dzinobatanidza kumusoro. Gear: muviri wesimbi wakaita koni unoumbwa negiya muviri nemazino. Mazino akakamurwa kuita marudzi maviri: mazino akagayiwa uye mazino ekuisa, mabearings uye neoiri yavo yekuchengetera sealing device nozzles.

2) Kushanda musimboti we roller cone bit Kana iyoroller cone bitinoshanda pazasi pegomba, chibooreso chose chinotenderera chakatenderedza axis yechibooreso, icho chinonzi revolution, uye makoni matatu anokunguruka pazasi petsime maererano nemasanhu avo, ayo anonzi kutenderera. Kuboorwa kunotsungirirwa nechibhorani kunoita padombo nemumazino, zvichiita kuti dombo rityoke (crushing effect). Munguva yekukunguruka, koni inobata pasi pegomba nemazino ega uye mazino maviri, uye nzvimbo yepakati yekoni inoshanduka, zvichiita kuti chibooreso chidengenyeke kwenguva refu. Iyi longitudinal vibration inoita kuti tambo yedrill irambe ichimanikidza uye kutambanudza. Iyo yepasi chibooreso tambo inoshandura iyi nguva nenguva ichichinja elastic deformation simba kuita simba rekuita pakuumbwa kuburikidza nemazino kuti aparadze dombo. Uku kukanganisa uye kupwanya mhedzisiro ndiyo nzira huru yekuti roller cone drill bit yekupwanya matombo.

Pamusoro pekukanganisa nekupwanya dombo pazasi petsime, roller cone bit inoburitsawo kugera padombo pazasi petsime. Nepo koni ichikunguruka pazasi petsime, inokonzeresa kuti mazino atsvedzerwe pazasi petsime. Kutsvedza kwemazino kunogadzira kugera padombo riri pazasi petsime, richikwesha pasi pegomba kunge scraper bit. Kutsvedza kwemazino kunonyanya kukonzerwa nepamusoro-pamusoro, yekubatsira koni uye kuchinjika kurongeka kwegumbo regiya. Kurongeka kwepamusoro-soro kwekoni kunokonzeresa kutsvedza munzira ine tangential, uye kuchinjika kurongeka kwekoni kunokonzera kutsvedza munzira yeaxial. Kazhinji,drill bitsnokuda kwekuchera zvinyoro kusvika pakati-zvakaoma zviumbwa zvakagadzirirwa nepamusoro-pamusoro, koni yekoni uye kushandura shafts; zviboorero zvekuboora zvepakati-zvakaoma kusvika kune zvakaoma maumbirwo akagadzirwa nepamusoro-pamusoro uye makonikoni; zvibooreso zvekuboora zvakaomesesa uye zvimiro zvinokwesha zvakagadzirirwa nepamusoro-pamusoro uye makonikoni. Drill bits dzinowanzoshandisa single cone cones, iyo isingapfuure kana kufambisa axis.

3) Kurongeka uye Kusarudzwa kweRoller Bits Kune vakawanda vanogadzira mabhiti e-roller, uye ava vanogadzira zvidhiraivho vanopa mabheti emhando dzakasiyana uye zvimiro. Kuitira kugonesa kusarudzwa nekushandiswa kwemaroller cone bits, International Institute of Drilling Contractors (IADC) yakagadzira yakabatana Classification mwero uye nzira yemanhamba yemaroller cone bits pasi rese. IADC inotaura kuti mhando yega yega yekuboora inomiririrwa nenhamba ine manhamba matatu, uye zvinoreva nhamba imwe neimwe ndeiyi inotevera:

• Nhamba yekutanga inoratidza rudzi rwezino uye kuumbwa kwakakodzera kuchera: 1- milling zino, kuumbwa kwakapfava; 2- zino rekukuya, pakati nepakati-yakaoma kuumbwa; 3- zino rekukuya, rakaoma, rinoputika kana semi-abrasive kuumbwa; 4- spare; 5-Zino, nyoro kusvika pakati kuumbwa; 6-Zino, yepakati-yakaoma kuumbwa; 7-Zino, rakaoma, rinoputika kana semi-abrasive kuumbwa; 8-Zino, kuoma zvakanyanya, kuumbwa kwakanyanya.
• Chidimbu chechipiri chinoratidza kuti dhizaini yakakamurwa kuita magiredhi mana ekuoma: 1, 2, 3, uye 4.
• Chidimbu chechitatu chinoratidza maitiro ekuumbwa kweiyo drill bit: 1- isina kuvharwa rolling bearing; 2- T-yakaita mutsara wekunze wemazino ekudzivirira dhayamita; 3- Isai mazino ekudzivirira dhayamita pane geji dhayamita; 4- Chisimbiso rolling bearing; 5- Yakavharwa inotenderedza inobereka pane geji dhayamita Pane zvinoiswa uye geji; 6- yakavharwa sliding bearings; 7- yakavharwa sliding bearings ane ekuisa uye geji pa geji; 8- inonangidzira tsime kutsauka mabhiti; 9 - vamwe.

Zvimiro uye zvakanakira roller cone drill bits:

• 1. Kutsemuka kwedombo kuine mativi maviri ekuchinja uye kugera, zvose kukanganiswa kwemazino uye kugera kunokonzerwa nekutsvedza, zvichiita kuti dombo rive nemazvo.
• 2. Inogadziriswa kune zvakasiyana-siyana zve strata uye inokodzera kudhiraivha mumatanho ose.
• 3. Iyo yekubooresa ine yakanaka yekuzvichenesa maitiro uye haisi nyore kuita madhaka.
• 4. Drill bit cost yakaderera.
