Whakauru ki te PDC Ngā Tāpuhi Whakamātau : Whakarerekētanga i te Tāwari Mōhiotia
Nō te mea he tūtohu whakarerekē te PDC (Polycrystalline Diamond Compact) kei ngā mahi tāwari mōhiotia. Ko tēnei ka taea i te wehewehe mai o ēnei pūtake tūtohu, nā runga i ō rātau huanga hangarau me ō rātau whenu matua, e hohono ana ki ngā pūnaha kaweawe me te kaha i waenganui i ngā pūtake tūtohu kotahi. Hei tā rātau hanga, ko tēnei e hiahia ana ki te whakarite i a rātau, ka pai ai ki ēnei iwa tūmomo wāhi tāwari, ka whakapai ai te hokohoko whānui o te tāwari.
Te Mahi o ngā Pūtake PDC ki te Whakatupu i te Kowhatu
Nā ngā pūtanga PDC e whai ana i tētahi mahi matua ki te whakangungu i ngā tahuhu kō whatititi, nō reira rātou e taea ai te tuku i ngā hiranga matataki pai ake. Ki wāhi kē mai i ngā pūtanga mea tawhito e whai ana i te whakamahue, e whakamahi ana ngā pūtanga PDC i tētahi mīhini whakarerekē hei whakapiki i ngā whenua, e noho pai rawa ana i te wā i te waihotanga o te ēnei. Mēnā ka kitea i ngā raraunga, ka whakanui ake ngā pūtanga PDC i te paihere whakamahi ki te kokonga i runga i ngā pūtanga tawhito e 30%. E āki ana te mīhini whakarereke i te mea metal cutting, kei reira te tukanga whakahaere me te tūponotanga ki te whakangungu i ngā whenua, ā, e āhei ana ngā kaiwhakahaere ki te hanga i te āhuatanga tuatahi mo ngā waehanga katoa.
Te Whakarerekētanga o te Tikanga Pūtanga Kokonga i roto i te Rōpū Pūngao me te Pūngao
I mohiohia te whakarerekētanga o te hanganga pūtake whakamahi i ngā tau, ā, in particular ko te whenua me te wai industry. Mai i ngā hanga tuatahi, kua huri ake ki ngā pūtake whakamahi matatika, pēnei i ngā PDC bits, he momo whakawhitinga matua i roto i te whenua. Ngā whakaaweawe i roto i te hanga matū kua puta i ngā PDC bits e taea ana te mahi i runga i ngā wehewehe me ngā pausanga nui. Hei tā ngā pūrongo, kua noho ake te whakamahere PDC bits, ka mutu i te 60% o te whakahaere whenua me te wai. Ko tēnei whakarerekē i whakaae ai ki tō rātou take kia taea te tuku whakamahi pai, te iti i ngā utu, me te whakapai i te ratitanga o ngā mahi.
He Whakariterite Rawa o ngā PDC Bits: Te Mana Hanganga
Ngā Kākano Diamond Polycrystalline: Te Tirohanga o te Whaiwhai
Kei te whakaaetanga ngā kaihoko diamona polikarihi hei manawa mō ngā pūtahi whakamahere PDC, e whai ana i tōna hiranga ki te whai wawata. E hanga ngā kaihoko nei i te mahi wehi me te waehu nui, ka whakatangitanga noa atu te whanaketanga o rātou. Ka puta he momo hangarau mīharo mai i tēnei, e whiwhi ana i te iti raweke, ā, kei te whai ake i tō rātou pūtake whakamahere moe roa i ngā taiao whakamahere kino. Ko tēnei hiranga ko te mea nui i ngā taiao whakamoe kitea e kore ai te whakahēkotia o ngā take, e hiaua ana te whaiwaha me te iti whenu. He mea kē ki te whakaatu i te whakamahi i te ao hangi, e taea ana e ngā pūtahi PDC e whai ake ana i ngā pūtahi tungsten carbide matua 2 ki 3 wa e roa ana, mea hoki he whakataunga pai utu mō ngā mahi whakamahere ā-wāhanga o nāianei.
Te Whakauru Rākau Tirohanga Tika me ngā Tauwhiringa Hiorangi
Kei te whakatu i te hanga o ngā pūtahi PDC ki ngā taumata rauemi whakapai kē, e whakamahia ana hei whakapai i te wehi o te kutu me te tango i te roa i runga i ētahi atu whenua. Ka whakapai anō he hanga whakaaro nei i te wehenga i ngā ara, ka whakapai hoki i ngā mahi kutu. He whakarite i ngā whiuwhiuinga ki roto i ngā pūtahi PDC hei āwhina i te tango herehere i ngā raraunga, ka noho pai tonu ai te wehi i te kutu. Kua kitea i ngā rorohiko hanga iwi e āhei ana ngā raraemi whiuwhiuinga whakapai kē ki te whakapai i te āeke o ngā wai kutu e 25% te kotahi, ka whakapai ake anō hoki i te wehi me te tirotiro i te kore raweke o ngā pūtahi i te take o ngā raraunga kua huihui, e hiahia ana ki te whakamana i ngā āhuatanga whakahaere pai.
Hanganga Whakaraweke Āheinga Mō Te Wā
Te whakangungu tuatahi o ngā pūtahi kōwhai PDC he tūmomo hangarau e whakatīnga ana i te wā o te whakamahi. Ko tēnei āhuatanga e whakaae ana ki ngā pūtahi kia mau tonu i te wehi o te kutu i runga i ngā kaupapa kutikuti nui, nā tēnei meitei e tiakina ana ngā whakapae e pā ana i te whakawhiti i ngā pūtahi. Ko te tirohanga kiko nui e iti iho ana i ngā uiui whakahaere me te whakamana i te waipū me te waenganui o te kutikuti. Hei tā ngā raraunga iwi, kei te kitea e ngā kāwanatanga e whakamahia nei ngā pūtahi kōwhai PDC kia puta mai ngā tautekore nui o te moni mea nā te itinga o ngā whakawhiti take, ko ēnei pūtahi ka noho hei whakangungu pai i te whakaiti moni kutikuti ahakoa te whakapai i ngā waewae o ngā kaupapa.
Nga painga o ngā pūtahi PDC i te whakakotahi i te kowheoro
Rahi ake o te whakatūpū (ROP) i roto i ngā whakatakanga nui
Nui ake ngā PDC bits i te whiwhi i te rahinga tuhinga nui, inā kē i ngā whenua kōhatu matatini. Ko tō rautaki he mihinare ki ngā pae totohi e whakapakari i te hiranga o te tuhinga, he mea hoki i whakaatuia i ngā whakamārama o te ao rēaaliti. Nō te mea nei, ko te whiwhi i ngā PDC bits ka puta te whakatūhono ROP i runga i te 50% i waenganui i ngā āhua pūkoro tradisionāl e mahi ana i runga i ngā āhuatanga taurite. Kua whakaatuia te wehewehe atu o enei whakatūhono i te take o te hanganga matataki o ngā PDC bits e āhei ana ki te mahi shearing nui i roto i ngā whenua kōhatu, hei whakaatu i ngā rorohiko paetae me ngā whakawhiti whaiaro.
Te Whai Take i te Wāhanga Hauware
Te whakapai hōu i te mahi tonu o ngā pūtahi PDC e whakawhiti ana ki ngā tirotiro moni, nō te itinga i ngā wā tripping e hīanga ana i roto i ngā mahi tūru. Ko te kupu 'tripping' he whakamārama i te mahi o te hoki i muri me te whakahoki anō i te kōrero tūru hei whakarere i te pūtahi tūru. Nā te hoahoa kino me te ao maha ka noho ake, e iti ana ngā pūtahi PDC i te hiahia mō ngā whakarere pūtahi anō. Ko tēnei iti iho i ngā wā tripping—kua āwhina i raro i te 20% i ratau iti—e āheinga ana i ngā ra katoa o ngā hononga tūru, e whakapai ana i te kaiwhakatō i te maha nei i te wā e hāngai ana.
Kupu Tuhituhi: 173% Whakatipu ROP i ngā Pūnaha Gasi o Te Māhutanga Ki Te Waehanga
Nā ngā rorohiko whakaata i te Mūrua Kīngitanga i whakamaramatia te pūtake hiranga o ngā kōpū tāwhiti PDC, ā tērā e noho pūmau ana i ngā pouaka mehemea, ko te hunga kawe i tēnei whakamātau he 173% te paihere ki te ROP. Nā te whakatau mōhio i waenganui i ngā kōpū tāwhiti matua me ngā kōpū PDC i kitea ai te pai ake o ngā kōpū PDC ki te whakapai i te mahi tāwhiti. Ko ēnei nui atu o te paihere i te ROP ka whakamana i te tono pai o te whanaketanga PDC ki te whakapai i ngā mahi whaimahi, ā, ko tā rātou hiahia nui ki te whakatika i te hoko taonga i roto i ngā taiao e angitia ana.
Ngā Whakamahi o ngā Kōpū Tāwhiti PDC Ki wāhi Rawa
Tāwhiti i te Para: Ngā Kōrero Whiwhinga mai i Eagle Ford me Wolfcamp
Nā ngā pūtē PDC i whakarerekē te mahi herehere i ngā whenua shale, ā tērā ki ngā whenua pūnaha pēnei i a Eagle Ford me a Wolfcamp. Kua puta mai i tēnā i te urutau o ngā moni mahi me te whakapai o ngā paihere. Hei tauira, e kīia ana i ngā pūrongo whakahaere i te mea ko te hunga PDC he mea nui ki te whakapai i ngā ratonga whakahaere mō te wā e hanga ai i runga i ngā tikanga hoko. Nā tēnei pūtē i hangaia hei tautoko i ngā herenga nui e pa ana ki ēnei whenua pūnaha, ka puta he pai ā-tatari, pērā i te iti iho i te wā e hanga ai, me te nui ake i te roa e hanga nei.
Ki roto i te whenua shale o Eagle Ford, nā ngā whakamahinga hou i ngā pūtē PDC i whakapai i te ROP i te wehewehe i te 40%. Ko tēnei i whakaae mai ki ngā tirotiro moni e utu nei me ngā paihere mahi. Ināianei, ki roto i te pūnaha o Wolfcamp, kua iti iho ngā wā e hanga ana i te 36% me te whakapai i te ROP i te 25%. E whakaatu ana ēnei kaitohutohu i te take whakarerekētanga o te hunga PDC ki ngā mahi herehere whenua shale o nāianei.
Te Whakahaere Herehere i ngā Pūnaha Rereki Sandstone
