Mastering Rock Crossing ndi Advanced TCI Tricone Bit.
1. Rock Crossing Directional Drilling
①Njira zobowolera molunjika pakuwoloka miyala ndi izi:
- Njira Yosavuta Yomanga
- DITCH WITCH Njira Yobowola Pakhoma Pawiri
- Pneumatic kapena HydraulicHammer ya Pansi-HoleImpact ndi Rotary Directional Drilling
- Njira Yobowola Matope Magalimoto
“Njira yobowola matope” ndiyo njira yomwe imagwiritsidwa ntchito kwambiri pobowola miyala m'nyumba ndi kunja. Ndi yoyenera pobowola matani 25 kupitilira apo, makamaka zida zazikulu zopanda ngalande.
Makina amatope, omwe amadziwikanso kuti screw drill, nthawi zambiri amaphatikizidwa ndi "chobowola cha tricone” kapena “Zithunzi za PDCPa kubowola kwabwinobwino, ndodo yobowola ndi mota zimazungulira palimodzi pobowola mizere yowongoka. Pobowola molunjika, nyumba yopindika ya injiniyo imagwirizana ndi malo a 12 koloko omwe akuwonetsedwa ndi chipangizocho. imazungulira pobowola, kukwaniritsa kubowola kolowera.
Kupindika kwa injini zamatope za "zopingasa kubowola zidutswa” nthawi zambiri zimakhala kuyambira 1.5 ° mpaka 3 °, ndipo kusankha kumadalira kupindika kwa njira yopangira mapaipi.
②Masinthidwe amalumikizidwe a Kubowola Matope Magalimoto:
- Wopanda zingwe: Bowola ndodo → Nyumba ya zida → Njinga →Ma Cones atatu amabowola Bit
- Wawaya: Ndodo yobowola → kolala yobowola yopanda maginito → Nyumba ya zida → kolala yobowola yopanda maginito → Njinga →Ma Cones atatu amabowola Bit
2. Kubowola Rock Crossing Reaming
Mukamaliza dzenje loyendetsa, kubwezeretsanso kumachitika potengera kukula kwa mapaipi.
2.1 Mitundu ya Rock Reamers
①Pali mitundu iwiri ikuluikulu yama rock reamers:
- Ma Tricone Rock Reamers Okhazikika: Izi zimagwiritsa ntchito zigawo za tricone cutter kuchokera ku zobowola mafuta ngati zida zodulira, zowotcherera ku shaft yapakati ya reamer ndi mbale yoyambira.
- Replaceable Roller Cutter Reamers: Zopangira izi zimagwiritsa ntchito zodulira zosinthika ngati zida zodulira, zomwe zimayikidwa m'mabulaketi kapena kuyimitsidwa.
②Ubwino ndi Kuipa kwaTricone Rock Bits
Ubwino:
- Kupanga kwakanthawi kochepa.
- Oyenera ma diameter osiyanasiyana (makamaka ang'onoang'ono mpaka apakati), kuyambira 220mm mpaka 1600mm, ndipo amatha kusintha mawonekedwe osiyanasiyana a geological.
- Mtundu wa mano osinthika komanso mawonekedwe otengera kutengera mawonekedwe ndi mapangidwe.
- Kuphwanya mwala wa hydraulic moyenera ndikuchotsa zinyalala.
Zoyipa:
- Kuvala kumbuyo kwa chodula kumakhala kovuta kuthana ndi mapangidwe a mchenga.
-Zotsegulira mabowoikhoza kutha pambuyo pokonza zingapo.
- Kuyika zisindikizo pamawonekedwe ocheka kumakhala kosavuta kulephera, ngakhale zida zotsutsana ndi dontho zimachepetsa zoopsa.
2.2 Mawonekedwe a Replaceable Roller Cutter Rock Reamer for Medium-Small Rigs
①Zowonjezera izi:
- Yankhani zovuta zovala kumbuyokukoka tinthu.
- Khalani ndi mtengo wofanana ndi wosindikizidwa mphiraZithunzi za TCI trione, kuchepetsa ndalama zoyendetsera ntchito.
- Onetsetsani kuti mukugwira ntchito yotetezeka komanso yodalirika yokhala ndi chosinthira chodulira chosavuta.
2.3 Mawonekedwe a Replaceable Roller Cutter Rock Reamers for Large Rigs
①Zinthu zazikulu ndi izi:
- Oyenera zida zolemetsa zolemetsa m'mawolo amiyala akulu akulu.
- Okonzeka ndi matupi osinthika komansoMabowo a HDD reamerzakonzedwa kuti zigwiritsidwe ntchito nthawi yayitali.
- Ma roller okhala ndi mano a Ø19 carbide ndi mbiri makonda (zosawoneka bwino za rock yolimba, conical for rock yofewa).
3. Kubowola Parameters
3.1 Kuthamanga Kwambiri
Kuthamanga kwa kubowola kumadalira zinthu monga kulimba kwa thanthwe, kukula kwa borehole, ndi mphamvu ya kubowola. Kupanikizika kwambiri pazida ngatiPDC kukoka pang'onozingayambitse kuwonongeka kwa zida.
3.2 Kuthamanga Kwambiri
Imasungidwa pa 40 RPM kapena pansi, kuwonetsetsa kuti zikuyenda bwino pazida ngaticore barrel kubowola zidutswa.
3.3 Kuyenda kwamatope
Kuyenda kwamatope moyenera ndikofunikira pakuziziritsa komanso kuchotsa zinyalala, makamaka mukamagwiritsa ntchitoAPI standard trione bitsm'mapangidwe a sandstone.
4. Dope Kusangalala System
Njira zophatikizira zoyeretsera matope zimathandizira pakubowola bwino. Amapulumutsa chuma ndikuchepetsa kuwonongeka kwa chilengedwe, mogwirizana ndi njira zamakono zoboola zomwe nthawi zambiri zimaphatikizazibowo zotsegulirandi njira zopanda trenchless.
Ubwino:
- Amabwezeretsa matope 80-90%.
- Amapulumutsa 40-50% ya bentonite.
- Amathetsa zovuta zakutaya matope ndikuchepetsa kuwononga chilengedwe.
