Izixhobo zeLandrill Oil zityhila iSikhokelo soKhetho lweSayensi lweePlagi zeBridge ezinyibilikayo

Kwicandelo elinzima lemisebenzi ye-oyile, ukukhetha ekuneneiplagi yebhulorho enyibilikayoibaluleke kakhulu ekwakheni nasekuveliseni amaqula ngokufanelekileyo. I-Landrill Oil Tools izise isikhokelo esibanzi sokukhetha esisekelwe kwizigqibo, esicwangcisa inkqubo yeengcali zoshishino.

Inyathelo 1: Ubushushu - Ukuhambelana kwezinto eziqhutywayo

Ubushushu bokwakheka yeyona nto iphambili. Ilawula uzinzo lobushushu kunye nesantya sokunyibilika kwezinto zeplagi yebhulorho. Kwiimeko zobushushu obuphantsi (ngaphantsi kwama-60℃), iimodeli zeSingle Slip okanye zeCompacted Double Slip ezifana ne-LZ001, LZ002, kunye ne-LZ022 zifanelekile. Ezi zibonelela ngobukhulu obuncinci (ubude ≤ 330mm) kunye nokunyibilika ngokukhawuleza (20 - 40mg · cm⁻² · h). Kwiimeko zobushushu obuphakathi (60 - 90℃), iiplagi zeCompacted Double Slip okanye zeDouble Slip ezifana ne-LZ008, LZ016, kunye ne-LZ027 ziyakhazimla, zibonelela ngozinzo oluphuculweyo lokubambelela kwiimeko zoxinzelelo oluphakathi (≤ 70MPa). Imithombo yobushushu obuphezulu (ngaphezulu kwama-90℃) ifuna izisombululo zeDouble Slip okanye zeFull Metal ezifana ne-LZ025, LZ030, kunye ne-LZ031, ezinokumelana noxinzelelo oluphezulu (85MPa) kunye nazo zonke - ukumelana nokugqwala kwesinyithi.

Inyathelo lesi-2: Uhlengahlengiso lwetyuwa kunye nokugqwala

Ubutyuwa (uxinzelelo lweCl⁻) kunye neendawo ezirhabaxa zinciphisa ukhetho ngakumbi. Imithombo yobutyuwa obuphantsi (ngaphantsi kwe-500mg/L) ifanelekile kwi-LZ001/LZ002 Series, kunye nesantya sokunyibilika se-20 – 40mg·cm⁻²·h. Kwiindawo ezinobutyuwa obuphezulu (ngaphezulu kwe-15000mg/L), i-LZ025/LZ028 Series ikhokela, inesantya sokunyibilika se-80 – 120mg·cm⁻²·h. Kwiindawo ezinobutyuwa (pH ≤ 3), i-Full Metal LZ030 Series iyacetyiswa, ngenxa yokwaleka kwayo okuxhathisa i-asidi kunye nesantya sokunyibilika se-20 – 300mg·cm⁻²·h kubushushu obuphezulu.

Inyathelo lesi-3: Izinto ekufuneka ziqwalaselwe xa kufikwa kwibhokisi kunye noxinzelelo

Ubungakanani bekheyisi kunye noxinzelelo lolwakhiwo nazo zibalulekile. Iikheyisi ezincinci (≤ 4″) zihambelana kakuhle neSingle Slip LZ001 (OD 89mm). Imisebenzi yoxinzelelo oluphezulu (ngaphezulu kwe-70MPa) ixhamla kwiDouble Slip LZ025 (Pressure 85MPa), enoyilo lokutyibilika olujikelezayo olunika amandla aphezulu okucheba angama-30%. Kwiikheyisi eziguquliweyo, iCompacted Double Slip LZ022 (OD 110mm) iqinisekisa ukugqithwa kwiikheyisi ze-4.5″.

Ngokulandela lo mthi wesigqibo, amaqela e-oyile anokukhetha ngokuchanekileyo iiplagi zeebhulorho ezinokunyibilika, ukuphucula ukusebenza kwemithombo kunye nokuqinisekisa ukusebenza okungenamthungo kwiimeko ezahlukeneyo zejoloji. Isikhokelo seLandrill Oil Tools sixhobisa eli shishini ukuba lijongane nemingeni enzima yemithombo ngokuchanekileyo kwesayensi.
