微破裂四维影像油藏精细监测技术及其应用

Fine Reservoir Monitoring Technology based on Four-dimensional Seismic Imaging of Microfractures and Its Application

微破裂四维影像油藏精细监测技术属于油藏地球物理范畴,它采用三分量检波器接受微破裂地震波,分析微破裂地震波振幅(即能量)向量属性,研究储层释放能量的大小、持续时间、变化规律、分布范围等要素,进而对油藏注水前缘、剩余油分布、人工裂缝发育情况进行科学、合理、客观地监测和判断。

Fine reservoir monitoring technology based on four-dimensional seismic imaging of microfractures comes into the domain of reservoir geophysics.It uses three-component detector to receive seismic wave,analyzes the vector properties of seismic wave amplitude,studies the size,duration,changing law,and distribution of energy released from reservoir,and then monitors and determines waterflooding front,residual oil distribution,and artificial fracture development scientifically,rationally,and objectively.
