Kulawa da Kula da PDC Drill Bits

Kulawa da gyara na yau da kullun na PDC (Polycrystalline Diamond Compact) rawanin hakowa suna da muhimmanci don haɓaka aikinsu da tsawon rayuwarsu. Dubawa da gyaran yau da kullun na iya ƙara inganci da tsawon rayuwar waɗannan rawunan.

Bincike na yau da kullum

Ana buƙatar duba PDC drill bits don lalacewa da kuma lahani bayan kowanne amfani. Duba alamun lalacewa a kan diamond cutters da duk wani lahani ga jikin bit. Dubawa na yau da kullum yana taimakawa wajen gano matsaloli tun da wuri da kuma hana tsadar gazawar yayin ayyukan hakowa.

Tsaftacewa da Ajiya

Bayan amfani, tsaftace PDC rawar ɗin rawar don cire duk wani tarkace ko ruwa na hakowa. Ajiye rawar a wuri mai bushewa da tsaro don hana lalata da lalacewa. Yanayin adanawa mai kyau yana da mahimmanci don kiyaye ingancin masu yankan lu'u-lu'u da jikin rawar.

Zaɓen Madaidaicin PDC Burin Rawar

Zaɓar madaidaicin PDC na'urar hakowa don takamaiman aikin hakowa ya dogara da abubuwa da dama, ciki har da yanayin ƙasa, sigogin hakowa, da manufofin aiki. Ga wasu mahimman la'akari don zaɓar madaidaicin PDC na'urar hakowa:

Yanayin Kasa

Nau'in da taurin dutsen suna da tasiri sosai akan aikin PDC na'urar hakowa. Misali, PDC na'urorin suna aiki sosai a cikin yanayin shale da sandstone amma suna iya saurin lalacewa a cikin yanayin da ke da yawan abrasive kamar granite. Bisa ga binciken da Kungiyar Injiniyoyin Man Fetur (SPE) ta gudanar, dacewar ƙirar na'ura da yanayin ƙasa na musamman na iya inganta ƙimar hako mai da tsawaita rayuwar na'ura har zuwa kashi 25%.

Ma'aunin Hakowa

Mafi kyawun sigogin hakowa, kamar saurin juyawa (RPM), nauyin kan bit (WOB), da karfin juyi, suna da matukar muhimmanci wajen inganta aikin PDC bit. Daidaita waɗannan sigogin bisa ga halayen ƙasa na iya haɓaka ingancin hakowa da rage lalacewar bit.

Nau'in Aikace-aikace

PDC rawanin hakowa ana amfani da su a cikin aikace-aikace daban-daban, ciki har da hako mai da iskar gas, hako geothermal, hako rijiyar ruwa, da binciken ma'adinai. Misali, Baker Hughes ya lura cewa a cikin Permian Basin, masu aiki sun ba da rahoton ƙaruwa da kashi 30% a cikin ingancin hakowa ta amfani da PDC rawuna.

Amfanin Tattalin Arziki na Amfani da PDC Drill Bits

PDC rawun hakowa suna bayar da fa'idodi masu yawa na tattalin arziki saboda ingancinsu mai girma, dorewarsu, da kuma dacewarsu. Ga wasu manyan fa'idodin tattalin arziki:

Kara Gudun Hakowa

Bits ɗin PDC an ƙera su don su daɗe fiye da bits na al'ada. Bayanai daga Halliburton suna nuna cewa bits ɗin PDC na iya daɗewa har sau 20 a cikin tsarukan da ba su da yashi, yana rage yawan sauyin bits da kuma lokacin dakatarwa da ke tattare da shi.

Rage Kudaden Aiki

Tsawon rayuwa da ingantaccen aiki na PDC bits yana haifar da ƙananan kuɗin aiki. Boreholes masu laushi da aka samar ta hanyar PDC bits suna kuma sauƙaƙe aikin casing da siminti, wanda ke rage farashi. American Petroleum Institute (API) ya nuna cewa boreholes masu laushi na iya haifar da adana kuɗi mai yawa a cikin kammala rijiyar.

Daban-daban a Aikace-aikace

PDC bits suna da amfani iri-iri kuma za a iya amfani da su a cikin aikace-aikacen hakowa daban-daban, ciki har da mai da iskar gas, geothermal, rijiyar ruwa, da binciken ma'adinai. Wannan amfani iri-iri yana sa su zama zaɓi mai tsada ga yanayin hakowa daban-daban.

Gaba ɗaya, fa'idodin tattalin arziki na amfani da PDC rawar soja suna sa su zama zuba jari mai mahimmanci ga ayyukan hakowa, suna taimakawa wajen rage farashi da ƙara inganci.

Don ƙarin bayani game da PDC rawar-burin, don Allah danna nan.
