摘要
酸压裂缝的缝长和导流能力是评价酸化压裂效果的2个重要指标,通过应用Fracpro PT软件对碳酸盐岩酸压过程中酸蚀裂缝导流能力和缝长变化趋势的拟合,总结了碳酸盐岩油气藏不同储层类型中的裂缝导流能力随缝长的变化规律,从裂缝导流能力随缝长的变化趋势中可以半定量判断碳酸盐岩储层中缝洞发育带的发育规模。拟合结果与地震和测井解释结果相结合,对定性和定量判断碳酸盐岩缝洞发育体的规模具有重要意义。
Based on the method of Nierode-Kruk theory, the change law between fracture conductivity and fracture length in different types of carbonate reservoir was obtained through fitting the change trend of the acid fracture conductivity with length variation, and the fracture-cave scale of the carbonate reservoir was semi-quantitatively determined based on this law. The fitting results combined with seismic and log interpretation has great significance on qualitative and quantitative judgment of the fracture-cave scale in the reservoir.
