Ho utloisisa Theknoloji ka morao ho PDC Bits
1) Litšobotsi tsa sebopeho sa li-drill tsa PDC
Likotoana tsa ho cheka tsa PDC li entsoe ka 'mele oa li-drill, meno a PDC le li-nozzles. Li arotsoe ka lihlopha tse peli: 'mele oa tšepe le' mele oa matrix ho ea ka mekhoa e fapaneng le mekhoa ea tlhahiso. 'Mele oohle oa karolo e thata ea ho cheka ea PDC o entsoe ka tšepe e bohareng ea khabone mme o sebetsoa ka mekhoa ea ho etsa mochini. Eketsa masoba holim'a sebaka sa ho sebetsa sa borona ebe u fasa meno a sehang a PDC moqhaka oa boro e nang le mochini oa khatiso. Moqhaka oa mochini oa ho phunya o tšoaroa ka mokhoa o thata oa holim'a metsi (ho fafatsa lesela le sa thibeleng la tungsten carbide, carburizing, joalo-joalo) ho matlafatsa khanyetso ea eona ea khoholeho. Molemo o ka sehloohong oa sekhahla sena sa ho phunya ke hore mokhoa oa ho etsa lihlahisoa o bonolo; bothata ke hore 'mele oa ho phunya ha o hanyetsane le khoholeho ea mobu le meno a ho itšeha a thata ho boloka, kahoo hona joale ha a sebelisoe hangata. Karolo e ka holimo ea 'mele oa boro ea matrix PDC drill bit ke' mele oa tšepe, 'me karolo e ka tlaase ke tungsten carbide wear-resistant alloy matrix, e entsoeng le ho etsoa ka mokhoa oa ho etsa phofo ea metallurgy sintering. Sebelisa solder e nang le mocheso o tlase ho cheselletsa meno a sehang a PDC ho li-grooves tse bolokiloeng setopong. Tungsten carbide matrix e na le boima bo phahameng 'me e hanyetsana le khoholeho ea mobu. Ka hona, "matrix PDC drill bit" e na le bophelo bo bolelele le litšoantšo tse phahameng, 'me hajoale e sebelisoa haholo.
2) Molao-motheo oa ho sebetsa oa PDC drill bit
Likotoana tsa ho cheka tsa PDC li pshatla majoe ka ho seha. Meno a itšeha a itšeha a ka khaola habonolo sebopeho tlas'a ketso ea khatello ea ho phunya, 'me a fetela pele ho kuta lejoe tlas'a ketso ea torque. Meno a mangata a ho itšeha a PDC a sebetsa ka nako e le 'ngoe,' me lejoe le ka tlaase ho seliba le na le libaka tse ngata tse sa lefelloeng, 'me lefika le robeha habonolo tlas'a ho kuta, kahoo matla a ho pshatla ha lefika a phahame mme lebelo la ho phunya le potlakile.
3) Tšebeliso e nepahetseng ea likotoana tsa PDC
Li-drill tsa PDC li sebetsa hantle haholo likarolong tse kholo tsa libopeho tse bonolo ho isa ho tse thata tse mahareng. Ha e loketse ho cheka likarolo tsa lehlohlojane le strata e bonolo le e thata. Ho sebelisa khatello e tlase ea ho cheka, lebelo le phahameng le ho phunya ho hoholo ha phalliso, karolo ea ho phunya e na le phello e ntle.
Pele karolo ea ho phunya e kena ka selibeng, tlase ea seliba e tlameha ho hloeka ho netefatsa hore ha ho na lintho tse oelang ka tšepe.
Ha setsi sa ho phunya se qala ho theoleloa selibeng, khatello e nyenyane ea ho phunya le lebelo le tlaase la ho potoloha le lokela ho sebelisoa ho tsamaisa mochine oa ho phunya, 'me ho phunya ho tloaelehileng ho lokela ho tsosolosoa ka mor'a hore ho thehoe tlase ea seliba. PDC drill bit ke karolo ea bohlokoa ea ho phunya ntle le likarolo tse tsamaeang 'me e loketse ho cheka turbine ea lebelo le phahameng.
Ha u khetha atšepe 'mele oa PDC phunya likotoana, ho na le lintlha tse 'maloa tse lokelang ho nahanoa ho netefatsa ts'ebetso e nepahetseng. Taba ea pele, ho bohlokoa ho lekola maemo a khethehileng a ho cheka le libopeho tsa sebopeho ho fumana moralo o nepahetseng oa sebono le litlhaloso. Lintlha tse kang mofuta oa sebopeho, botebo ba ho cheka le lebelo le hlokahalang la ho phunya li tla susumetsa khetho ea 'mele oa tšepe o nepahetseng oa PDC bakeng sa mosebetsi.
Ho feta moo, ho bohlokoa ho ela hloko sebopeho sa lisebelisoa le boleng ha u khetha tšepe ea 'meleLikotoana tsa ho cheka tsa PDC. Ho behoa le boholo ba lisebelisoa tsa ho itšeha ho phetha karolo ea bohlokoa ho khethollang bokhoni ba ho itšeha le ho tšoarella ha drill. Lisebelisoa tsa ho itšeha tsa boleng bo holimo tse sebelisang theknoloji e tsoetseng pele ea PDC li ka ntlafatsa ts'ebetso e akaretsang le bophelo ba ts'ebeletso ea mochini oa ho cheka, ho etsa hore e be letsete la bohlokoa bakeng sa merero ea nako e telele ea ho cheka.
Ho phaella moo, moralo oa mosebetsi oa hydraulic oa drill bit o ke ke oa hlokomolohuoa. Sistimi e sebetsang ea haeteroliki e bohlokoa ho boloka meaho ea ho seha e hloekile ebile e pholile, haholo maemong a thata a ho cheka. Sistimi e entsoeng hantle ea hydraulic e thusa ho thibela li-pelletizing le ho netefatsa ho tlosoa ka katleho ha li-cuttings, ho thusa ho ntlafatsa ts'ebetso ea ho cheka le bophelo bo fokolang.
Ka bokhutšoanyane, ka ho nahana ka litlhoko tse khethehileng tsa ho cheka le ho khetha lisebelisoa tsa boleng ba tšepe tsa PDC tse nang le moralo le likarolo tse nepahetseng, litsebi tsa ho phunya li ka eketsa katleho ea ho cheka le ho fumana liphello tse phahameng ka mekhoa e thata.
