为确定一有界封闭圆形油藏的孔隙体积V(进而确定储量N)和流动系数kh/μ,常用压力降落分析的方法。利用压降曲线的非定常早期段可得到kh/μ,利用该曲线的非定常晚期段可测得V和kh/μ,而利用该曲线的拟定常期段,则可获得V。往往在压力降落测试之后再随之以压力恢复测试,以验证刚进行过的压力降落测试是否确已达到了拟定常期,同时处理此压力恢 In order to determine the pore volume V (and thus the reserve N) and the flow coefficient kh / μ for a bounded closed circular reservoir, the pressure drop analysis method is commonly used. Use kh / μ for the unsteady early period of the pressure drop curve, V and kh / μ for the late unsteady period of the curve, and V for the proposed constant period. Often in the pressure drop test followed by pressure recovery test to verify the pressure drop test just done has indeed reached the proposed permanent, while dealing with this pressure recovery
