Unyango lomphezulu we-downhole motor- isisombululo esiphumelelayo sokuphelisa ukugqwala kwi-brine egcweleyo

1. Ndiyisombulule ngempumelelo ingxaki yokugqwala kwityuwa eyomileyo.

Uthelekiso lwendlela yokucubungula:

a. I-Chromium plating yeyona ndlela isetyenziswa kakhulu okwangoku. Ama-90% abathengi bepetroleum basekhaya basebenzisa le ndlela, enobomi obufutshane benkonzo kwaye ixabiso layo liphantsi. Eyona ngxaki inkulu ye-electroplating kukungcola kokusingqongileyo, kwaye i-electroplating ayinakusebenza kwi-saturated brine.

b. Xa kutshizwa i-WC, abathengi ngokusisiseko bafuna i-WC coating kwizixhobo zokugrumba, ukongeza ekugugeni okunamandla, ikwamelana ne-hydrogen sulfide, amanzi anetyuwa kunye nokunye ukugrumba. Ingxaki kukuba ixabiso liphezulu, kwaye inzuzo kukuba ixesha elide lisebenza. Isixhobo sokugrumba sisetyenziswe ngaphezulu kweeyure ezingama-600 kwaye sisaphelele, kwaye singasetyenziswa ngokuqhelekileyo kwi-brine egcweleyo.

2. Itekhnoloji yokugquma isombulula ingxaki yokugqwala kwamanzi anetyuwa egcwalisiweyo

a. Itekhnoloji yokwaleka (izisa isisombululo esiphumelelayo kwingxaki yokugqwala emanzini anetyuwa egcweleyo kuphela)

Iimpompo ze-slurry zineendawo ezibonakala zi-helical ezibizwa ngokuba yi-"lobes" ezine-4, 5 okanye 7 lobes phezulu ezibizwa ngokuba yi-crests (okanye i-crests). Ii-crests zenza "ububanzi obuphambili". Ubungakanani obuphambili buyahluka ukusuka kwi-4.0 ukuya kwi-6.5 intshi, nto leyo eba luluhlu lobungakanani benjini.

Ingongoma ephantsi ibizwa ngokuba yi-trough (okanye i-trough), kwaye i-trough yenza "ububanzi obuncinci". Umgama oqhelekileyo ukusuka kwi-lobe ukuya kwi-trough umalunga ne-¼-intshi (6.35mm). Kukho iimfuno ezingqongqo kakhulu ze "wave top" embindini we-motor kunye "nokutsiba" phakathi kweziphelo ezimbini. Njengomgangatho, ixabiso "lokubaleka" kufuneka libe ngaphantsi kwe-0.010″ (0.254 mm). Nantoni na engaphezulu kunye nepayipi yerabha yepompo iya kutshatyalaliswa ngokukhawuleza xa i-motor ijikeleza ngexesha lokusebenza.

ukulungiswa komphezulu

a. Kwi-spray coating, akufuneki ukuqhumisa i-grit. Umphezulu kufuneka ucocwe ngezixhobo zesandla kuphela xa kuyimfuneko okanye kufuneka ususwe amafutha. Ukutshiza kusengasetyenziswa njenge-backup, xa kufuneka ucoce umphezulu ngokukhawuleza okanye ukulungisa inxalenye ye-spray coating.
