Zusammenfassung:	Disclosed are an oil production amount prediction method and an apparatus thereof. The oil production amount prediction method comprises the step of: (a) calculating the amount of precipitation of barium sulfate or strontium sulfate according to changes in barium or strontium ion concentrations before and after applying a low salt injection method to a simulation model; (b) analyzing at least one of permeability reduction and wettability conversion according to the changes in barium or strontium ion concentrations before and after applying the low salt injection method to the simulation model; and (c) predicting an oil production amount of a reservoir by using the calculated amount of precipitation of barium sulfate or strontium sulfate and the at least one analyzed result of the permeability reduction and wettability conversion. 오일 생산량 예측 방법 및 그 장치가 개시된다. 오일 생산량 예측 방법은, (a) 시뮬레이션 모델에 저염수주입 공법 적용 전후의 바륨 또는 스트론튬 이온 농도 변화에 따른 황산바륨 또는 황산스트론튬 침전량을 계산하는 단계; (b) 상기 시뮬레이션 모델에 상기 저염수주입 공법 적용 전후의 상기 바륨 또는 스트론튬 이온 농도 변화에 따른 투과도 감소 및 습윤도 변환 중 적어도 하나를 분석하는 단계; 및 (c) 상기 계산된 황산바륨 또는 황산스트론튬 침전량과 상기 투과도 감소 및 습윤도 변환 중 적어도 하나의 분석 결과를 이용하여 상기 저류층의 오일 생산량을 예측하는 단계를 포함한다.
