Zida za Mafuta a Landrill Zavumbulutsa Buku Losankhira Sayansi la Mapulagi Osungunuka a Mlatho

Mu gawo lovuta la ntchito zamafuta, kusankha koyenerapulagi yosungunuka ya mlathondi wofunikira kwambiri pa ntchito yomanga ndi kupanga zitsime bwino. Landrill Oil Tools yapereka malangizo omveka bwino okhudza kusankha zinthu pogwiritsa ntchito mtengo, zomwe zingathandize akatswiri pantchitoyi.

Gawo 1: Kutentha - Kugwirizana ndi Zinthu Zoyendetsedwa

Kutentha kwa kapangidwe kake ndiye chinthu chofunikira kwambiri. Kumalamulira kukhazikika kwa kutentha ndi kuchuluka kwa kusungunuka kwa zipangizo za pulagi ya mlatho. Pa malo otentha kwambiri (pansi pa 60℃), mitundu ya Single Slip kapena Compacted Double Slip monga LZ001, LZ002, ndi LZ022 ndi yabwino kwambiri. Izi zimapereka miyeso yaying'ono (kutalika ≤ 330mm) ndi kusungunuka mwachangu (20 - 40mg · cm⁻²·h). Pa kutentha kwapakati (60 - 90℃), mapulagi a Compacted Double Slip kapena Double Slip monga LZ008, LZ016, ndi LZ027 amawala, zomwe zimapangitsa kuti zikhale zolimba kwambiri pamavuto apakati (≤ 70MPa). Zitsime zotentha kwambiri (zoposa 90℃) zimafuna mayankho a Double Slip kapena Full Metal monga LZ025, LZ030, ndi LZ031, omwe ali ndi kukana kwakukulu kwa kuthamanga (85MPa) ndi zina zonse - kukana dzimbiri kwachitsulo.

Gawo 2: Kusintha kwa Mchere ndi Dzimbiri

Mchere (Cl⁻ concentration) ndi malo owononga zinthu zimawonjezera kukana kusankha. Zitsime za mchere wochepa (pansi pa 500mg/L) ndizoyenera LZ001/LZ002 Series, ndi kuchuluka kwa kusungunuka kwa 20 - 40mg·cm⁻²·h. Mu kuchuluka kwa mchere wochuluka (kupitirira 15000mg/L), LZ025/LZ028 Series imatsogolera, yokhala ndi kuchuluka kwa kusungunuka kwa 80 - 120mg·cm⁻²·h. Pa malo okhala ndi asidi (pH ≤ 3), Full Metal LZ030 Series ndi yovomerezeka, chifukwa cha utoto wake wosagwirizana ndi asidi komanso kuchuluka kwa kusungunuka kwa 20 - 300mg·cm⁻²·h pa kutentha kwakukulu.

Gawo 3: Kuganizira za Chikwama ndi Kupsinjika

Kukula kwa chivundikiro ndi kupanikizika kwa kapangidwe kake n'kofunika kwambiri. Mabokosi ang'onoang'ono (≤ 4″) amagwirizana bwino ndi Single Slip LZ001 (OD 89mm). Ntchito za kupanikizika kwakukulu (kupitirira 70MPa) zimapindula ndi Double Slip LZ025 (Pressure 85MPa), yomwe ili ndi kapangidwe kotsetsereka kawiri kuti ikhale ndi mphamvu yokwezera 30%. Pa mabokosi opindika, Compacted Double Slip LZ022 (OD 110mm) imatsimikizira kuti mabokosi a 4.5″ amatha kupitika.

Potsatira mtengo wosankha uwu, magulu a malo opangira mafuta amatha kusankha bwino mapulagi a mlatho omwe angathe kusungunuka, kukonza magwiridwe antchito a zitsime ndikuwonetsetsa kuti ntchito zake sizimasokonekera m'malo osiyanasiyana. Buku la Landrill Oil Tools limapatsa mphamvu makampaniwa kuthana ndi mavuto ovuta a zitsime molondola kwambiri.
