Chifukwa Chiyani Mafuta ndi Gasi M'zigawo Sizichita Popanda Ma Aloyi Olimba?

Pofufuza zamafuta ndi gasi mkati mwa Dziko Lapansi, zobowola zolimba zolimba zimakhala chida chakuthwa cha anthu polimbana ndi miyala yolimba, zomwe zimakhala ngati chitsimikizo cholimba cha njira yaku China yakuzama pansi.

M'madera akutali a Tarim Basin, chitsime cha Yuejin 3-3XC cha "Deep Earth No. 1" chadutsa kale kukumba kwakuya kwa mamita 10,000. Derali, lomwe lili ndi mikhalidwe yovuta kwambiri yazachilengedwe, imafuna kuti zinthu zobowola zikhale zovuta kwambiri. Chomwe chimagonjetsa madera ovutawa ndi "mano achitsulo ndi nsagwada zachitsulo" zopangidwa ndi aloyi olimba.

I.  Zovuta Zakuya Padziko Lapansi, Zovuta Pobowola

Pamene kufufuza kwa mafuta ndi gasi ku China kukupita patsogolo kwambiri, minda yamafuta ikuyang'anizana ndi "malo atatu okwera kwambiri" -kuzama kwambiri, kutentha kwambiri, kuthamanga kwambiri, komanso sulfure.

Pazifukwa zotere, mabowola wamba amavutika kuti agwire. Zobowola zachikale zimatha msanga, zimakhala ndi moyo waufupi, komanso kuchepa kwachangu, zomwe zimalephera kukwaniritsa zofuna zamasiku ano pobowola mafuta ndi gasi.

Mphamvu ndiye maziko amakampani. Mafuta ndi gasi ozama kwambiri padziko lapansi akhala gawo lofunikira kwambiri pakukula kwamafuta ndi gasi ku China, zomwe zimapangitsa kuti pakhale kofunika kuthana ndi zovuta zaukadaulo pakubowola.

II.  Ma Alloys Olimba: Chida Chofunikira Chothana ndi Mapangidwe Olimba

Mafuta olimba asanduka chinthu choyenera pobowola mafuta ndi gasi chifukwa cha kulimba kwawo, kulimba kwawo, ndiponso kusavala kwapadera.

Amapangidwa ndi sintering tungsten, cobalt, ndi zitsulo zina za ufa pa kutentha kwakukulu, zomwe zimapangitsa kuti zikhale zolimba kuposa 90 pa sikelo ya Mohs—kuposa zitsulo zamakono.

III.  Kupambana Kwaukadaulo ndi Zopangira Zapangidwe

Pofuna kuthana ndi mapangidwe ozama komanso ovuta, ukadaulo wa hard alloy drill bit ukupitiliza kupanga.

Odula a Polycrystalline diamond compact (PDC) omwe amagwiritsidwa ntchito pobowola mafuta ndi gasi amakhala ndi gulu lolimba la aloyi komanso wosanjikiza wa diamondi wophatikizidwa nawo.

Thupi lolimba la aloyi limatenga zinthu ziwiri zosanjikiza—mkati mwake wopangidwa ndi silinda yolimba yolimba kwambiri komanso wosanjikiza wakunja wopangidwa ndi chubu lolimba kwambiri, losamva kutentha kwambiri, ndipo pakati pake pali chubu cholimba chachitsulo chosatentha kwambiri.

Kapangidwe kameneka kamapangitsa kuti pakatikati pa gawo lolimba la alloy alloy ali ndi kulimba kwambiri komanso mphamvu, pomwe kunja kumapereka kuuma kwakukulu komanso kukana kukokoloka kwapadera, zomwe zimapangitsa kuti zikhale zoyenera pakubowola kwamphamvu kwambiri komanso kukokoloka kwakukulu.

IV.  Kugwiritsa Ntchito Mwachangu Kumawonetsa Phindu

Zobowola zolimba za alloy zimagwira ntchito yofunika kwambiri pakubowola mafuta. Amatha kuthana mosavuta ndi magawo osiyanasiyana a miyala yolimba, monga granite ndi quartzite.

Mabatani a hard alloy akuwonetsa kuuma kwakukulu kwambiri ndi kukana kuvala kwapadera, zomwe zimawathandiza kuti apirire mkangano waukulu ndi kutha pobowola nthawi yayitali.

Zida zolimba za alloy zimaperekanso kukana kwambiri, zomwe zimawalola kupirira zovuta zingapo mwadzidzidzi panthawi yobowola, kuwonetsetsa bata ndi kupitiliza pobowola.

V.  Zoyembekeza Zam'tsogolo ndi Zovuta Zili Patsogolo

China's "14th Five-Year Plan" explicitly emphasizes enhancing oil and gas supply capacity and improving development standards, charting the course for the advancement of hard alloys in the oil and gas drilling sector.

Pamene kuya kwa mafuta ndi gasi kukukulirakulira komanso kubowola bwino, zofunikira pakubowola zolimba zikweranso.

Mabizinesi amakampani tsopano akuyang'ana kwambiri kafukufuku, chitukuko, ndi kupanga mabatani apamwamba kwambiri komanso magawo apamwamba a PDC ochotsa mafuta ndi gasi. Akuyang'ana pa kafukufuku wazitsulo zobowola mozama, kuyesetsa kuthetsa zovuta za "bottleneck" pakubowola mphamvu za dziko ndi zida zofukula miyala.
