摘要
Based on repeated comparisons of well logging and related geological data,the authors identified 4 types of shattered fault zones in the Dongxin Oilfield of the Jiyang Depression.By examining structural and distributional characteristics of shattered fault zones with different sizes in the Yong-3 block,the authors found that the thickness,petrophysics and displacement pressure of induced fractures and fragment fillers were key factors for the fault sealing property.The distribution of shattered fault zones was then mapped and applied to the allocation of 3 horizontal wells so as to recover the remaining oil in fault blocks.
