Portlatishga qarshi preventor (BOP) kolonnasi eng kuchsiz komponenticha kuchli. Ram va annular preventorlarning har biri ma'lum funksiya uchun tanlanadi. Ushbu taqqoslash ram va annular BOP konstruksiyalarini yonma-yon baholaydi.

Ram preventori: Mexanik ishchi ot

Ram preventori gorizontal qarama-qarshi po'lat bloklardan foydalanadi. Qurilma turlari: quvur ramlari (burg'ulash quvuri atrofida germetizatsiya), ko'r ramlar (ochiq teshikni berkitish), kesuvchi ramlar (quvurni kesib, quduqni berkitish).

Annular preventor: Moslashuvchan germetizatsiya

Annular preventor halqa shaklidagi elastomer elementdan foydalanadi. Bir annular preventor 2-3/8" dan 7-5/8" gacha quvurlarni, kvadrat kellylarni va asbob ulanishlarini germetizatsiya qilishi mumkin.

Ram va annular preventorlar o'rtasidagi tanlov kolonna konstruksiyasi masalasidir. Standart quruqlik operatsiyalari uchun 3 preventorli kolonna etarli. JLD Energy bilan bog'lanib, o'zingizning burg'ulash dasturingiz uchun BOP kolonnasi konfiguratsiyasini oling.

Ko'p so'raladigan savollar

JLD Energy o'z preventorlarini qanday sinovdan o'tkazadi?
JLD Energy barcha preventorlari API 16A bo'yicha sinovdan o'tkaziladi: gidrostatik korpus sinovi, past (200-500 PSI) va yuqori (100%) bosimli o'tirgich sinovi.
