Izinzuzo Nezinselele Ekusebenziseni I-PDC Cutter Embonini Kawoyela Negesi

Abasiki be-polycrystalline diamond compact (PDC) sebedume kakhulu embonini kawoyela negesi ngenxa yekhono labo lokukhulisa ukunemba nokulawula ukumba. Nokho; ngesidingo esikhulayo semithombo ejulile futhi eyinkimbinkimbi, i-PDC cutter ibhekene nezinselelo eziningi embonini kawoyela negesi. Kulesi sihloko, sizohlola izinzuzo zabasiki be-PDC kanye nezinselele eziningi ezibhekene nembonini kawoyela negesi yesikhathi esizayo.

Izinzuzo ze-PDC Cutters:

1. Ukuzinza Nokuqina

Izisiki ze-PDC zenziwe ngezinhlayiya zedayimane zokwenziwa ezihlanganiswe ndawonye ngaphansi kwezinga lokushisa eliphezulu nokucindezela, okuzenza ziqine kakhulu futhi zizinze. Lokhu kuzinza nokuqina kuvumela ukubhola okunembe kakhudlwana nokulawula kangcono inqubo yokumba.

2. Ukufana

Abasiki be-PDC baklanyelwe ukuthi babe nesimo esifanayo kanye nosayizi, okuvumela ukubhola okungaguquguquki kanye nama-boreholes abushelelezi. Lokhu kufana futhi kunciphisa ingozi yokuchezuka endleleni yokumba ehleliwe, okwandisa ukunemba kokumba.

3. Ukuguquguquka Komklamo

Abasiki be-PDC bangaklanywa ngamajiyometri athile kanye nezakhiwo zokusika ukuze bakhulise ukusebenza kwabo ohlelweni oluthile lokubhola. Lokhu kuguquguquka kwedizayini kuvumela ukubhola okunembe kakhudlwana ekwakhekeni kwamadwala ahlukahlukene, okuhlanganisa ukwakheka okuqinile nokunama-abrasive.

4. Ukudlidliza Kwehlisiwe

Izisiki ze-PDC zenzelwe ukunciphisa ukudlidliza ngesikhathi sokumba. Lokhu kuncipha kokudlidliza kuvumela ukulawula kangcono inqubo yokumba, okuholela ekubholeni okunembe kakhudlwana nokuncipha kokuguga emishinini yokumba.

5. Izikhathi Zokubhoboza Ezisheshayo

Abasiki be-PDC banolaka futhi bayashesha kunamathuluzi okumba endabuko, okuvumela izikhathi zokumba ngokushesha kanye nokubhola okunembe kakhudlwana. Lokhu kukhula kwesivinini sokumba kuphinde kunciphise ingozi yokuchezuka endleleni yokumba ehleliwe, okuholela ekubhobolweni okunembe kakhudlwana.

Sengiphetha, ukuzinza, ukuqina, ukufana, ukuguquguquka komklamo, ukudlidliza okuncishisiwe, nezikhathi zokumba ngokushesha zabasiki be-PDC konke kunomthelela ekwandeni kokunemba nokulawula ukumba. Ukusetshenziswa kwezisiki ze-PDC kuguqule imboni kawoyela negesi, okuvumela ukumba okunembe nangempumelelo.

Izinselelo zabasiki be-PDC:

1.Izindleko eziphezulu zokuqala zabasiki be-PDC

Abasiki be-PDC babiza kakhulu kunamathuluzi okumba endabuko, okungaba isithiyo ekuthathweni kwabo. Izindleko zabasiki be-PDC zingaba ukutshalwa kwezimali okukhulu kwezinkampani zokumba, ikakhulukazi kuma-opharetha amancane. Kodwa-ke, ukonga izindleko zesikhathi eside ezihambisana nabasiki be-PDC kungase kudlule ukutshalwa kwezimali kokuqala.

2.Ukutholakala okulinganiselwe kochwepheshe abanamakhono

Ukuklama izisiki ze-PDC zezinhlelo zokusebenza ezithile zokumba kungaba inselele. Idizayini yabasiki kufanele icabangele ukubunjwa kwe-geological ethize okumbayo, kanye nemingcele yokumba, njengesisindo kubhithi nesivinini sokujikeleza. Lokhu kudinga ukuqonda okuphelele kwendawo yokumba kanye nezakhiwo zamadwala ambiwayo.

I-3.Izinkinga zokuhambisana nezinqubo ezithile zokumba kanye nemibandela

Abasiki be-PDC baklanyelwe ukumelana nezinga lokushisa eliphezulu nokucindezela, kodwa kukhona ukulinganiselwa ekusebenziseni kwabo. Kwezinye izinhlelo zokusebenza zokumba, njengokumba okunokushisa okuphezulu, abasiki be-PDC bangase bangakwazi ukumelana nezimo ezimbi kakhulu, okuholela ekugqokeni ngaphambi kwesikhathi kanye nokwehluleka.Nakuba abasiki be-PDC beqinile kakhulu, baphinde bahlakazeke. Lokhu brittleness kungaholela ekuchithweni nasekuphuleni uma abasiki bebhekene nomthelela omkhulu noma ukushaqeka. Lokhu kungaholela ekwehliseni ukusebenza kahle kokumba kanye nokwenyuka kwesikhathi sokuphumula.

Ukuze unqobe lezi zinselele, ukubambisana phakathi kwabakhiqizi, opharetha, nabahlinzeki besevisi kubalulekile. Ngokusebenzisa ubuchwepheshe obuqoqiwe nezisetshenziswa zomkhakha, singathuthukisa izixazululo ezintsha ezithuthukisa ukusebenza nokuthembeka kwabasiki be-PDC embonini kawoyela negesi. Ngokwesibonelo, endaweni yokuthuthukiswa kwe-Negros eseningizimu ye-Philippines, i-elementi yedayimane eyi-conical (CDE) eqanjiwe (CDE) yakhelwe ucwaningo lwendawo olujulile kakhulu lwemithombo, futhi ukuguga okuhambisanayo, okuhambisanayo, okuhambisana namandla okuguga okuhambisana ne-PDC okuhambisanayo okuklanywayo okuthuthukisiwe okuphakeme kuqhathaniswa ne-PDC. Ezinye izinkampani ziqala ngenqubo yokukhiqiza i-drill bit, efana nokushisa okuphezulu okusha kwe-Schlumberger kanye nobuchwepheshe bokukhiqiza ithuluzi elincane le-PDC, elithuthukisa amandla amancane we-PDC futhi linciphise okuqukethwe kwe-cobalt, ngaleyo ndlela ithuthukise ukuzinza okushisayo nokumelana nokugqoka kwesakhiwo sedayimane, ukuhlolwa kwelabhorethri kubonisiwe. Amathuluzi e-HTHP anikeza ukuguga okuphezulu nokumelana nokukhathala okushisayo kunamathuluzi ajwayelekile e-PDC, akhuphuka cishe ngamaphesenti angu-100 ngaphandle kokuphazamisa ukumelana nomthelela. Akugcinanga lapho, amazwe angaphandle aphinde aklama izingcezu zokubhola ezihlakaniphile. Isibonelo, ngo-2017, u-Baker Hughes wakhulula i-TerrAdapt, i-drill bitana yokuqala yemboni, enesilawuli esilungisa ngokuzenzakalelayo ukujula kwebhithi ukuze kuthuthukiswe isivinini sokumba ngokusekelwe ezimeni zamatshe okwakheka. I-Halliburton yethule isizukulwane sayo esisha sobuchwepheshe be-adaptive bit, i-Cruzer TM deep cut ball element, elungisa ngokuzenzakalelayo imingcele yokubhoboza ukuze ibe nezimo zemigodi ephansi, inciphisa kakhulu i-torque ngenkathi ikhulisa i-ROP futhi ikhulisa ukusebenza kahle kokubhola.

Uma unentshisekelo ku-PDC CUTTERS futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE Imeyili ezansi ekhasini.
