新庄油田不同类型断块油藏含油高度分析

为了总结新庄油田油层分布规律,根据已发现的断块特征,将其划分为三种断块圈闭类型,从断层封闭性角度分析论证了各类断块油藏含油高度小和含油高度有所差异的原因,认为断层两盘砂、泥岩对置的概率小,断层封闭性差决定了各断块含油高度较小的普遍性,而不同类型断层封闭能力的差异则造成了各断块含油高度有所不同,并对今后的勘探和开发评价提出了建议。

Analysis of oil columns in different types of fault block reservoirs in Xinzhuang oilfield

In order to understand the distribution patterns of oil layers in Xinzhuang oilfield, three types of fault block traps are classified according to the characteristics of the discovered fault blocks. The causes that the oil columns are short and have certain differences in each kind of fault block reservoirs are analyzed in respect of fault sealing. capacities. It is believed that the small probability of juxtaposition of the sandstone and mudstone in the upper and lower fault plates and the poor sealing capacities of faults would have determined the universally short oil columns in each fault blocks, while the differences of sealing capacities between different types of faults would have resulted in the differences of oil columns in each fault block. Some proposals are presented for future exploration and development appraisals.
