小时内定产情况下的井底流压。该井采用井下关井装置，因此井筒储存效应可以不考虑。根据数据分析油藏渗透率（5 分）、表皮系数（5 分）、达到拟稳态的时间（5 分），并估计油藏大小（5 分）。分析时将下表红色标出的油藏孔隙度?最后一位改为学号最后一位，比如学号最后一位为 9，则?为 0.19。（提示：参考课件第三章的内容，在把各物理量转换为相应的单位后，首先画出井底流压随对数时间的变化图，计算直线段斜率 m，根据下面给出的渗透率k 与 m 的关系式推出渗透率，并计算表皮系数；再画出井底流压与线性时间的关系图，拟稳态出现于直线段开始所对应的时间；从图中计算该直线段的斜率，进一步可计算出油藏的半径。见下文给出的所需公式。）表 2 题目 5 所需数据油藏参数油藏参数?0.15 Ct(psi-1)12*10-6 rw(ft)0.333 pi(psia)2500 h(ft)32 uo(cP)2.0
