裂缝张开度 meaning in Chinese
fracture opening
Examples
- By combining the conventional log data with the data on imaging logging , core , drilling - log and production test , etc . , and on the basis of carrying out various additional conduction corrections for resistivites , the fracture opening may be calculated by use of the difference between the resistivities of dual laterallog ; the fracture porosity can be estimated according to a simplified dual laterolog interpretation formula ; and the fracture permeability may be acquired in light of the experimental relation between the fracture widths and the fracture permeabilities
将常规测井资料与成像测井、岩心、录井、试油等资料相结合，在对电阻率进行各种附加导电校正的基础上，利用双侧向电阻的差异计算裂缝张开度，根据简化的双侧向解释公式计算裂缝孔隙度，根据裂缝宽度与裂缝渗透率实验关系求解裂缝渗透率。 - ( 3 ) we can detection the azimuth of crack growth by abnormal amplitude or the discrepancy of wave - speed . ( 4 ) we can guess whether crack contains fluids by the change of p - wave speed . second , using pore model , under press and temperature , we have studied the influences of pore density on the characteristic parameters of seismic wave
第一、利用人工裂缝模型，研究了裂缝密度、方位和张开度的变化对地震波属性参数的影响，根据实验结果，总结出：可利用横波分裂的不同程度来检测裂缝密度的高低；可利用纵横波的振幅、主频、衰减(或品质因子q )和主振幅的变化来检测裂缝张开度的变化；可利用速度的差异和振幅异常来检测裂缝发育的方向；可利用纵波速度的变化来推测裂缝中是否含流体。
