【摘要】 低序级断层使含油断块的油水关系复杂化,尤其是对于单砂体空间分布连续性较差、砂体内部结构非均质性明显的区块,低序级断层的识别对于寻找有利井位、解决注采矛盾非常有利。在卫星油田卫21区块为单一背斜构造基础上,采用葡萄花油层组密井网资料,考察分析同一井排井资料反映的葡顶构造位置的相对变化趋势,结合地震剖面,有效地实现了该区块低序级断层的识别,为加密井方案设计提供依据。更多还原

【Abstract】 The low order faults lead the oil-water relationship of oil-bearing block reservoirs complicated,especially in those blocks that show poor continuity of single sand spatial distribution and obvious heterogeneity of sand internal structure.The recognition of low order faults plays an important role in finding favorable well location and solving injection contradictions.Based on a single anticlinal structure of Wei 21 Block in Weixing oil field,the relative variation trend of Putaohua top location reflected in the well information of named well line by using the dense well pattern material of Putaohua reservoir group are investigated and analysed,and achieved the goal of low order fault recognition in this block effectively in conjunction with seismic profiles,so as to provide foundations in designing interspaced well project.更多还原
