Tsanangudzo yeOil Casing Connections

Mumabasa ekuchera mafuta, mhando yekubatanidza yemidziyo yekuchera chinhu chakakosha uye chakaoma. Mhando yekubatanidza haingokanganisa mashandisirwo ezvishandiso chete asi yakakoshawo pakuchengetedza nekugona kwemabasa ekuchera. Kunzwisisa akasiyana marudzi ekubatanidza kunobatsira vashandi kuita sarudzo dzakaringana maererano nekusarudza zvinhu, kugadzirira, uye nhungamiro yekushandisa. Chinyorwa ichi chinopa tsananguro yakadzama yezvakajairwa pombi yemafuta ekubatanidza, kusanganisira EU, NU, uye New VAM, uye inosuma muchidimbu kubatana kwepombi yekuchera.

Common Oil Pipe Connections

1. EU (External Upset) Connection
   • Hunhu: Kubatana kweEU imhando yekunze yakagumbuka yejoinhi yepombi yemafuta iyo inowanzoisa imwe yekuwedzera yekukora kunze kwejoinhi kuti iwedzere kusimba kwayo uye kusimba.
   • Makona: Mumusangano, macherechedzo akasiyana ekubatana kweEU anosanganisira:
     • EUE (External Upset End): Mhedziso yekugumbuka kwekunze.
     • EUP (External Upset Pin): Kunze kushungurudza murume kubatana.
     • EUB (External Upset Bhokisi): Kunze kushungurudza mukadzi kubatana.
   • Misiyano: EU neNU zvinongedzo zvinogona kutaridzika zvakafanana, asi zvinogona kusiyaniswa zviri nyore nehunhu hwazvo hwese. EU inoratidza kugumbuka kwekunze, nepo NU isina chinhu ichi. Pamusoro pezvo, EU kazhinji ine shinda 8 painch, nepo NU ine gumi painch.
2. NU (Isina-Kugumbuka) Connection
   • Hunhu: Iyo NU yekubatanidza haina dhizaini yekushungurudza yekunze. Musiyano mukuru kubva kuEU kusavapo kwekuwedzera kwekunze ukobvu.
   • Markings: Kazhinji inomakwa seNUE (Isina-Kugumbura End), zvichiratidza kupera pasina kugumbuka kwekunze.
   • Misiyano: NU kazhinji ine gumi neshinda painch, iyo yakakura density kana ichienzaniswa ne8 shinda painch muEU kubatana.
3. New VAM Connection
   • Hunhu: Iyo Itsva VAM yekubatanidza inoratidzira muchinjika-chikamu chimiro icho chakanyanya rectangular, ine yakaenzana shinda pitch spacing uye shoma taper. Iyo haina dhizaini yekushungurudza yekunze, inoita kuti ive yakasiyana neEU neNU.
   • Chitarisiko: Itsva VAM tambo dziri trapezoidal, zvichiita kuti zvive nyore kusiyanisa kubva kune mamwe marudzi ekubatanidza.

Common Drilling Pipe Connections

1. REG (Regular) Connection
   • Hunhu: Iyo REG yekubatanidza inoenderana neiyo API zviyero uye inoshandiswa kune yakajairwa tambo yekubatanidza pombi dzekuchera. Iyi mhando yekubatanidza yakashandiswa kubatanidza mukati inogumbura mapombi ekuchera, kuve nechokwadi kusimba uye kugadzikana kwemajoini epombi.
   • Thread Density: REG yekubatanidza inowanzova neshinda 5 painch uye inoshandiswa kune madhayamita epombi hombe (akakura kupfuura 4-1/2”).
2. IF (Internal Flush) Connection
   • Hunhu: Iyo IF yekubatanidza inopindiranawo neAPI zviyero uye inowanzoshandiswa pakuchera pombi dzine madhayamita ari pasi pe4-1/2”. Iyo tambo dhizaini yakakura kana ichienzaniswa neREG, uye magadzirirwo acho anonyanya kutaurwa.
   • Thread Density: KANA zvinongedzo kazhinji zvine tambo ina painji uye zvinowanzoitika kune mapaipi madiki pane 4-1/2”.

Summary

Kunzwisisa uye kusiyanisa marudzi akasiyana ekubatanidza kwakakosha pakushanda zvakanaka kwezviitwa zvekuchera. Imwe neimwe mhando yekubatanidza, yakadai seEU, NU, uye New VAM, ine chaiyo dhizaini maficha uye mamiriro ekushandisa. Mumapombi ekuchera, sarudzo pakati peREG uye IF kubatana kunoenderana nedhayamita yepombi uye zvinodiwa zvekushanda. Kuzivana nemhando idzi dzekubatanidza uye mamaki avo kunobatsira vashandi kuita sarudzo dzine ruzivo, kuve nechokwadi chekushanda uye kuchengetedzeka kwemabasa ekuchera.
