摘要
常用的调剖剂量计算公式为V=πR^2hφ+v,该公式以套管为中轴、以调剖深度R为半径、以砂层厚度h为高的圆柱体地层的孔隙体积πR^2hφ(φ为孔隙度,v为附加剂量)为基础设计的。实际施工中,这种设计与实际施工剂量有很大的误差,为此提出了近井孔隙体积+远井双曲线舌进孔隙体积的设计公式V=[0.5 n+(?)lnR_i/(R_jcosπ/n)]R_j^2hφsin(2π/n)(其中,n为地层水窜流个数,R_j为近井调剖半径;R_i为第i个窜流上的最大调剖半径)。
The profile controlling agent dosage is often calculated using the formula as follows：V=πR^2hФ＋v,in which R is a radius of circle, h is sand layer thickness, v is dosage of additives, Ф is porosity. But there exists a big error between the theoretical and practical dosage. Thus, another designing formula is proposed as follows, which takes near borehole pore volume and far borehole hyperbola fingering pore volume into consideration ：V=[0.5n＋^i=n∑lnRi/（Rjcosπ/n）]Rj^2hsin（2π/n）（ n is the number of formaus in the direction of no. i cross flow）.
