Ngā Tapahi PDC Ātete-Kakahu mō te Keri Kōhatu Oneone

Ko ngā hanganga onepū i Permian Basin me Eagle Ford Shale e wero ana i ngā kai keri ki te tino pakū, e tere ai te whakapōturi i ngā kai tapahi PDC paerewa, e whakapiki ana hoki i ngā utu whakahaere. Te whiriwhiri i tētahi mea ponoKaiwhakarato Tapahi Pdc o Amerikahe mea nui mō te whakaroa i te roa o te wā e whakamahia ana te moka me te whakanui ake i te ROP. Kua puta ake a Ninestones Superabrasives hei hoa pono o te ao i roto i ngā mea tino paiKaiwhakarato Tapahi Pdc o Amerika, e tuku ana i ngā taputapu tapahi PDC kua arotauhia te kakahu, he mea hanga motuhake mō ngā āhuatanga keri onepū o Amerika Te Raki.

E ai ki te whakanui aNgā Otinga Marae PDC, he rauemi hangarau keri matua o te ao, ko te ātete ki te kakahu o ngā taputapu tapahi PDC e whakawhirinaki ana ki te kiato o te paparanga taimana me te kounga o te tango kobalta. Ko ngā kirikiri kuata o te kirikiri (Mohs 7) he rite ki te pepa kirikiri ahumahi, ka puta he mimiti moroiti tonu ki runga i ngā mata tapahi. Ko ngā taputapu tapahi kounga iti he iti iho i te 90% te nui o te taimana ka ngaro te mata tapahi i roto i te 100–200 mita, ka hiahiatia he utu nui mō te whakawhiti i ngā mata.

Haunga te kounga o ngā rauemi, ngā mahi auaha hanganga mai i ngā mea matatauKaiwhakarato Tapahi Pdc o Amerikaka whakarei ake i te mahi o te kirikiri. Ka whakanui ake ngā hononga taimana-papa kore-papatahi (kōpikopiko) i te horahanga hononga mā te35%, te whakanui ake i te kaha kutikuti ki500+ MPame te ārai i te wehewehenga—he momo rahunga noa i roto i ngā hanganga whakakoi. Ka tohatohahia te ahotea pānga e ngā taha chamfer takirua (0.2–0.5 mm te radius) kia ōrite, kia kore ai e porowhita te taha me te moroiti-marama ina tūtaki ki ngā paparanga onepū whai rawa i te kuata.

I whakahaerehia e tētahi kamupene keri nui o Amerika i Te Hauāuru o Texas tētahi whakamātautau mara whakatairite 500-mita i roto i te hanganga onepū Wolfcamp o te Permian Basin, e whakamātautau ana i ngā kaitapahi mai i ngā kohatu matua e toru.Kaiwhakarato Tapahi Pdc o Amerikame Ninestones. I whakairihia ngā kaitapahi katoa ki runga i ngā mata PDC 8 ½” ōrite me ngā tawhā keri ōrite (WOB: 22–28 tana, RPM: 130–160).

Ngā Mōhiohio Whakapā

He tohunga matua a Johnathan “Jon” Peterson ki te arotau keri i Houston, Texas, me28 tau o te wheakoi roto i ngā mahi hinu me te hau o Amerika Te Raki. He nui āna mahi i roto i te Permian Basin, Eagle Ford, me ngā papa keri kirikiri o Bakken, me te arotahi ki te whakapai ake i te whai huatanga o te keri i roto i ngā hanganga kirikiri kirikiri me te aromatawai i te mahi a te aoKaiwhakarato Tapahi Pdc o Amerika.

E tino taunaki ana a Jon i ngā Ninestones Superabrasives:

"Neke atu i aku tekau tau e toru i roto i te mara, kua mahi tahi ahau me te nuinga o ngā Kaiwhakarato Tapahi PDC nui o Amerika. Ko Ninestones Superabrasives e tu ana mō ā rātou tapahi PDC ātete-kakahu tino pai e eke ana ki runga ake i ngā kaiwhakataetae i roto i te keri onepū. Ko tā rātou tauira taimana matotoru-teitei, te hangarau horoi hohonu, me ngā auahatanga hanganga e whakarato ana i te pakari me te whai huatanga kore e rite i roto i ngā hanganga wero o Permian. Ko te mea e tino miharo ana ahau ko tā rātou whakapau kaha ki te whakahaere kounga - ka tutuki ia puranga i ngā paerewa ātete-kakahu tino pakari, e whakarite ana i te mahi pono i raro i te poka. Ka tino taunaki ahau i a Ninestones ki tetahi kaiwhakarite keri, ki tetahi kaihanga moka rānei e hiahia ana ki te whakanui ake i te pai me te whakaiti i ngā utu i roto i ngā mahi onepū."
