Yayin da buƙatar binciken makamashi mai zurfi a duniya ke ƙaruwa, haƙar mai mai zurfi (fiye da mita 10,000) ta zama wani yanki mai mahimmanci don buɗe albarkatun mai, iskar gas, da na ƙasa. Duk da haka, yanayin ramuka masu tsanani—zafin jiki har zuwa 250°C, matsin lamba sama da 140 MPa, da kuma tarin duwatsu masu tauri—sun daɗe suna haifar da ƙalubale marasa misaltuwa ga na'urorin haƙar mai na gargajiya. A yau, China Far Eastern (CFE) tana alfahari da bayyana sabuwar na'urar PDC Bit ta 2026, wacce aka ƙera don shawo kan waɗannan mawuyacin yanayi da sake fayyace iyakokin ingancin haƙar mai mai zurfi.
Babban Kalubalen Hakowa Mai Zurfi
A zurfin da ya wuce mita 8,000, yanayin zafi na ramin ƙasa sau da yawa ya wuce 200°C, wanda ke tura daidaitattun sassan PDC (Polycrystalline Diamond Compact) zuwa iyakar zafinsu. Masu yanke PDC na al'ada suna fama da graphitization da saurin lalacewa a yanayin zafi sama da 150°C, wanda ke haifar da faɗuwa akai-akai, jinkirin shigar ruwa (ROP), da hauhawar farashin aiki. Tsawon shekaru, injiniyoyin haƙa rami sun sha wahala da babban ciniki: dorewa da sauri a cikin zafi mai tsanani. Sabuwar ƙirƙira ta CFE ta kawar da wannan sulhu.
Nasarar CFE: Kwanciyar Hankali a Zafin Zafi na 245°C & Ƙarfin Haƙa Mita 10,000
An gina shi bisa ƙwarewar filin mai na shekaru da dama da kuma masana'antar da aka ba da takardar shaidar API/ISO, PDC Bit na 2026 High-Zazzabi ya haɗa fasahohi uku na farko a masana'antu don samar da aiki mara misaltuwa:
1. Masu Yanke PDC Mai Cire Mai Zurfi: Ta amfani da ingantaccen sintering mai zafi mai ƙarfi (HPHT), masu yanke CFE suna kiyaye kaifi mai ban mamaki da juriyar lalacewa a zafin jiki na 245°C—50°C sama da matsakaicin masana'antu. Wannan yana hana lalacewar zafi kuma yana tabbatar da aikin yankewa akai-akai a cikin 超 - zurfin da yanayin zafi.
2. Jikin Matrix Mai Ƙarfafawa & Tsarin Hana Girgizawa: An ƙera shi da ƙarfe mai ƙarfi na tungsten carbide, jikin matrix na bit ɗin yana ba da juriya mai ƙarfi ga tasiri. Tsarin ruwan wukake masu kyau (ruwaye masu lanƙwasa 4-6) da kariyar ma'aunin karkace suna rage girgizar igiyar haƙa da kashi 60%, suna rage guntun abin yankawa da kuma tsawaita rayuwar bit ɗin da kashi 40% a cikin tsarukan da suka yi tauri da juna.
3. Tsarin Sanyaya Na'urar Hydraulic Mai Ci Gaba: Bututun da aka ƙera da kyau suna ƙara zagayawa cikin ruwa, suna rage zafin saman abin yanka da 30-40°C da kuma hana ƙwanƙwasawa a cikin yadudduka masu mannewa na shale ko claystone. Wannan yana tabbatar da matsakaicin ROP ko da a cikin yanayin da ke da zurfin ruwa mai saurin kamuwa da ruwa.
Aikin da aka Tabbatar a Fage: Kafa Sabbin Rikodi a Duniya
Jirgin ruwan CFE 2026 mai yawan zafin jiki PDC Bit ya kammala gwaje-gwaje masu tsauri a wasu daga cikin mawuyacin yanayin haƙa rijiyoyin mai a duniya, inda ya samar da sakamako mai ban mamaki:
• Tarim Basin, China (Rijiyar Mai Zurfi Mai Zurfi 10,910): Wannan ramin ya haƙa ramin dutse mai zurfin mita 2,100 na 220°C granite da gneiss a cikin gudu ɗaya, inda ya cimma matsakaicin ROP na mita 5.8 a kowace awa—sau biyu cikin sauri fiye da na al'ada. Ya kammala rijiyar kwanaki 10 kafin lokacin da aka tsara, wanda ya adana kimanin dala $280,000 a lokacin rijiyar.
• Tafkin Sichuan, China (mita 8,866 mai zurfi): A cikin tsarin duwatsun yashi da dutse mai ƙarfi, bitar ta rage ayyukan tuntuɓewa da kashi 50% kuma ta faɗaɗa tsawon bidiyo ɗaya zuwa mita 850, wanda ya nuna ci gaba da kashi 35% idan aka kwatanta da bitar PDC ta yau da kullun.
• Aikin Tsarin Zafin Ƙasa na Gabas ta Tsakiya (mita 7,200): Tare da yanayin zafi na ramin ƙasa na 230°C, injin ya ci gaba da aiki na tsawon awanni 180, yana dawwama a kan injinan da ke fafatawa da sauri sau biyu kuma yana rage farashin haƙa da kashi 40% a kowace mita.
An ƙera shi don Binciken Makamashi Mai Zurfi na Duniya
An ƙera shi don rijiyoyin mai/gas masu zurfi, haƙa ƙasa mai zafi, da kuma binciken ma'adinai mai zurfi, rabe-raben PDC masu zafi na CFE suna samuwa a girma daga 3 7/8" zuwa 17 1/2", tare da ƙididdige ruwan wukake da za a iya gyarawa (3-9) da kuma tsarin yankewa don dacewa da takamaiman ƙalubalen ƙira.
