Ilmiy tadqiqot yo‘nalishi:

Birjinslimas suyuqliklarning g‘ovak va yoriq-g‘ovak muhitlarda sizishi, g‘ovak va yoriq-g‘ovak muhitlarda modda ko‘chishi, anomal sizish va modda ko‘chishi, elastik-plastik sizish, relaksasion sizish, sizish va modda ko‘chishining teskari masalalari, neft va neftegaz konlari ishlatilishini tahlil qilish va loyihalash.

Ilmiy tadqiqotlarining asosiy natijalari:

Bir nechta yangi gidrodinamik modellar ishlab chiqqan. Xususan, dinamik faktorlarni hisobga olgan yangi kinetika tenglamasi asosida birjinslimas suyuqliklar kolmatatsion-suffozion sizishi modelini tuzgan. Ikkita yangi fizik paremetrlarni kiritgan holda umumlashgan sizish modelini yaratgan. Fraktal tuzilishga ega bo‘lgan ikki o‘lchovli g‘ovak muhitlarda moddalarni ko‘chirish masalalarini anomal xususiyatlarni hisobga olgan holda sonli yechgan. U noturg‘un qatlamlar uchun elastik-plastik sizish nazariyasini yaratgan. Bu nazariya tog‘ oralig‘i botiqligida joylashgan chuqur neft konlarini loyihalash tizimlarini baholashda muvaffaqiyatli qo‘llangan. U yoriq-g‘ovak muhitlarda relaksatsion sizish nazariyasini asoslagan. Shu nazariya asosida oldin kuzatilmagan, uzulishlar tarqalishining unimodal qonuniyatini topgan. Nokorrekt va teskari masalalarni yechish asosida neft quduqlarini gidrodinamik tadqiq etishning yangi uslubini yaratgan.
