The reservoir was modeled by homogeneous two-phase media based on BISQ model,and the effects of the squirt flow on the fundamental guided waves propagating in a borehole embedded in(saturated) porous media excited by monopole,dipole and quadrupole point sources were studied.
用B iot-喷射流统一模型(B ISQ模型)模拟孔隙地层,研究岩石喷射流对充流体井孔中声导波传播特点的影响。
Compared with Biot model, BISQ model predicts that the attenuation of P2 waves is very large at low frequency and decreases with increasing characteristic squirt flow length ( R ), the velocity low frequency limit is not zero and decreases with increasing R , variation of the ratio of pore fluid displacement to b.
与Biot理论对比 ,BISQ模型中慢纵波的衰减随频率降低急剧增大 ,且随喷射流长度的减小而增加 ;相速度随喷射流长度的减小而增加 ,其低频极限值不是零 ;孔隙流体位移与固相骨架位移之比的幅值随喷射流长度的增加而减小 ,其相位特点与Biot模型预测的不同 ;在流体与孔隙介质的边界上可产生更大的渗流 。
