【摘要】 利用三维地震、钻/测井等资料,通过对渤中凹陷石南断层活动速率的研究和统计,结合该区沉积体系的研究,探讨了其对砂体分布的控制作用。研究表明,石南断层可分为近EW、NNE、EW三个走向的分支断层。断层活动性强的位置,形成厚度较大的砂体,砂体的平面延伸范围小;断层活动性弱的位置,形成的砂体厚度较小,但平面延伸范围大。更多还原

【Abstract】 By using 3-dimensional seismic and drilling,logging data and in combination with the rate of fault activity of Bozhong Depression and study of depositional system in this area,the control of activity ratio on Shinan fault sandbody distribution was discussed.The result shows that Shinan fault zone is divided into three parts and their strikes are EW、NNE、EW.On the plane,the fault activity is strong,the thick sand body is formed,its extending area is small,where the fault activity is weak,the thickness of sand body is small,its plane extending range is big.更多还原
