Abstract

Production of oil and gas in production wells or reservoirs gradually decreases over time due to the accumulation of production interfering substances. This problem can be solved relatively simply and economically by injecting acid to remove these substances. However, proper acid treatment design and field operation are crucial due to the possibility of the formation incurring damage and for more effective stimulation of the reservoir. In this study, the overall process of matrix acidizing for oil wells in southern Alberta, Canada is summarized, together with descriptions of demonstration cases in preliminary research, acid treatment design, and field application process.

유·가스 생산은 생산이 지속될수록 생산정 내부 또는 저류층에 생산방해 물질이 침전되기 때문에 점차 생산되는 양이 감소하게 된다. 이러한 문제는 산(acid)을 주입하여 생산방해 물질을 제거함에 따라 비교적 간단하고 경제적으로 해결할 수 있다. 하지만 산에 의한 지층 손상 가능성과 보다 효과적인 지층자극(stimulation)을 위해 적절한 산 설계 및 현장 운영이 무엇보다 중요하다. 본 연구에서는 캐나다 앨버타 주 남부 유정(oil well)을 대상으로 암체 산 처리(matrix acidizing) 수행에 대한 전반적인 과정을 정리하였으며, 사전 연구, 산 처리 설계 및 현장 적용 과정으로 구분하여 각각의 실증사례에 대해 기술하였다.
