API 12 1/4 mainchesi hybrid bit for hard rock deep deep oilwell pobowola

Zobowola zophatikiza zili ndi ma cones 3 ndi masamba 3 kuposa ma premium roller cone.
Kumayambiriro kwa zaka za zana lapitalo, chulucho kubowola pang'ono m'malo scraper mu zolimba abrasive mapangidwe ntchito, koma izi kubowola shale ndi zofooka zina mu mapangidwe pulasitiki makamaka chifukwa cha kukanikiza downhole matope paketi kugwira ntchito, ndi pobowola mozama ndi bottomhole kuthamanga ndi kuwonjezeka. chiwerengero cha matope, matope paketi chodabwitsa adzakhala kwambiri. Kuti athetse vutoli, kwa zaka zambiri opanga makina obowola apanga zinthu zosiyanasiyana, koma osapambana. Poganizira za chodula chokhazikika kapena kubowola pang'ono pankhaniyi osakhudzidwa, anthu adayamba kuyesa kuphatikiza mitundu iwiri ya kubowola. Ndi kutchuka ndi kugwiritsa ntchito ma bits a PDC ndi ukadaulo wa PDC wodula kuti muwongolere zodulira za PDC m'mapangidwe osiyanasiyana pang'onopang'ono m'malo mwa cone bit. Koma m'mapangidwe olimba, abrasive ndi machitidwe ovuta kubowola, chifukwa cha ntchito, PDC kubowola pang'ono sikungalowe m'malo mwa cone bit. Pofuna kusewera zabwino za ma roller cone ndi PDC kubowola, kampani yathu yapanga pompopompo cholumikizira cholumikizira ndi PDC kam'badwo watsopano kabowola wophatikizika. Tikuyambitsa kubowola kophatikizana Pali mapangidwe awiri, imodzi ndi mapiko ang'onoang'ono, mapiko ang'onoang'ono, awiri-cone, ina ndi yokulirapo pang'ono ya mapiko a Mito, mapiko a tricone, Kutengera mapiko a mipeni anayi ndi masamba asanu ndi limodzi a PDC kubowola, ndi masamba a vice ndi malo amfupi adasinthidwa kukula kwa chulucho. Chifukwa chake, malo apakati a borehole amakhala pa mapiko a dotolo a PDC odula athunthu, ndipo gawo lozungulira pobowola lomwe limamalizidwa ndi ocheka ndi masamba komanso mbali yozungulira ya thanthwe lomwe limasweka movutikira, kusweka kwa miyala. zotsatira zimadalira chulucho ndi masamba ndi mating.
Ukadaulo wobowola wa Hybrid umaphatikiza ma cones odzigudubuza ndi odulira okhazikika a PDC kukhala amodzi, mapangidwe ovomerezeka kuti achepetse nthawi yobowola komanso kuyenda munjira zovuta kwambiri. bits, ukadaulo uwu umawonjezera ROP, umathandizira kuchotsa kudula, ndikupulumuka pamapangidwe ophatikizika ndi kusasinthika kwa magwiridwe antchito komanso kuwongolera bwino kwa zida.
Tekinoloje ya hybrid drill bit
odzigudubuza ndi ma polycrystalline diamondi compact (PDC) osasunthika odula kuti akhale amodzi, ovomerezeka kuti achepetse nthawi yobowola ndi maulendo muzinthu zovuta kwambiri. Ndi mphamvu yakuphwanyidwa kwa thanthwe ndi kukhazikika kwa ma cones odzigudubuza komanso kudulidwa kwapamwamba ndi kumeta kosalekeza kwa zidutswa za diamondi, teknolojiyi imawonjezera ROP, imathandizira kuchotsa kudula, ndikukhalabe ndi mapangidwe osakanikirana kwambiri ndi machitidwe osasinthasintha komanso kuwongolera bwino kwa zida. Padziko lonse lapansi, zobowola zosakanizidwa zakhala zikugwiritsidwa ntchito m'maiko 47 ndipo akuboola zambiri
kuposa 1 miliyoni ft (304,800 m).
