Abstract

Shale gas reservoir are composed of very fine grained particles, and their pores are very small, at the scale of nanometers. In this study, a parametric study was implemented to investigate the effect of knudsen diffusion, relative permeability and permeability reduction in shale gas reservoir. Shale gas reservoir model in Horn-River was developed to confirm the productivity for different design parameters such as diffusion, relative permeability, connate water saturation, and permeability reduction.

셰일 저류층은 매우 미세한 입자로 구성되어 있으며, 공극의 크기가 나노미터에 불과하다. 본 연구에서는 셰일 암체에서의 크누센 확산영향, 균열대 및 암체에서 상대투과도, 셰일가스 생산에 따른 균열투과도 변화를 적용하여 그 영향을 분석하였다. 이를 위해 캐나다 혼리버 셰일 저류층 모델을 구축하였으며, 장기간 생산을 하는 셰일 저류층에서의 확산 및 선행연구에서 제안된 균열대 상대투과도를 적용하여 생산성에 미치는 영향을 분석하였다. 그리고 암체와 균열대에서 동생수가 생산성에 미치는 영향과 저류층 생산에 따른 균열투과도 변화를 적용하여 생산성을 평가하였다.
