【摘要】 无源地震监测水驱前缘技术是近年开始应用于油田开发中后期的一项新技术,通过对无源地震原理及摩尔-库伦理论、断裂力学准则、波速场分布与地下渗流场分布的关系等的分析,确定无源地震监测技术可以应用于监测水驱前缘。通过对塔中4油田注水井TZ4-16-8进行水驱前缘的实时监测,证明该技术可以实现对水驱前缘的变化情况、水驱波及范围、优势注水方向等的实时监测,为评价区块水驱开发效果和剩余油分布研究提供直接资料。更多还原

【Abstract】 Sourceless seismic monitoring of waterflooding front is a new technique applied in the mid-late life of oilfield development in recent years.Analysis of sourceless seismic theory,Kurl-Moore theory,breaking mechanics,and the relationship between wave velocity field distribution and subsurface percolation field distribution has shown that sourceless seismic monitoring can be used for detecting water front.It has been proved in Injector TZ4-16-8 that this technique can perform real time monitoring for the change of water front,sweep area,and predominant direction of water injection,thus providing data for evaluation of waterflooding response and study of residual oil distribution.更多还原
