URANNI YER OSTIDAN SKVAJINALAR ORQALI ISHQORLASH USULI BILAN QAZIB OLISH TEXNOLOGIYASIDA YUZ BERUVCHI MURAKKABLIKLARNING YUZAGA KELISH SABABLARINI VA ULARNI HAL QILISH USULLARINI TAHLIL QILISH
Referat
Maqola rangli va radiaktiv metallarni yer osti skvajina orqali qazib olish tizimi ekspluatatsiyasi xususiyatlarini ko‘rib chiqishga bag‘ishlangan. Bosim skvajinalari orqali ruda qatlamiga yuvuvchi reagent yuborilishi, foydali komponentning eritilishi va so‘ngra uni sathga chiqaruvchi skvajinalar orqali tashilishi kabi texnologik jarayon tasvirlangan. Tizim ekspluatatsiyasi davomida yuzaga keladigan asosiy murakkabliklar aniqlangan: skvajina og‘ziga yaqin zonaning kolmatatsiyasi, gaz ajralishi, qum ko‘rinishi, nasos-kompressor uskunalarida tuzlar cho‘kishi. Ushbu jarayonlar ishlab chiqaruvchi qatlam jinslarining filtrlash va gidrodinamik xususiyatlarini o‘zgartirishi qayd etilgan, bu esa texnologik parametrlarni muntazam ravishda tuzatishni talab qiladi. Ekspluatatsiya samaradorligini oshirish usullari bayon etilgan bo‘lib, ular kimyoviy, fizik-kimyoviy va mexanik ta’sirlarni o‘z ichiga oladi. Skvajina og‘ziga yaqin zonaga va uskunalarga kompleks ta’sir ko‘rsatish orqali tizimning barqaror ishlashini ta’minlash, murakkabliklarning oldini olish va skvajinalarning xizmat muddatini uzaytirish zarurligi asoslab berilgan. Olingan natijalar mavjud va istiqbolli konlarda YOSOQO tizimlarini loyihalash va optimallashtirishda qo‘llanilishi mumkin.
