摘要
酒西盆地单北油田下第三系火烧沟组砂岩油藏长期以来被认为是水动力圈闭油藏的范例。根据水动力圈闭油藏形 成和保存的条件以及单北油藏目的层地下水动力条件等实际资料对所谓“单北水动力油藏”进行了分析，发现：即使单北 地区火烧沟组砂岩储层是一个完整的挠曲构造而根本没有被断层切割的话，那么目前的水动力条件也绝不可能形成“水 动力圈闭”。
The Shanbei oil pool in Jiuxi basin with sandstone reservoir beds of the Huoshaogou Formation of the Eogene,has long been taken as an example of hydrodynamically trapped oil pools. The author made a profound analysis about the so-called Shanbei hydrodynamically trapped oil pool according to the theoretical conditions for the formation and preservation of a hydrodynamic trap and the practical hydrodynamic conditions of Shanbei oil pool,and found that even if the sandstone reservoir beds of Huoshaogou Formation in Shanbei area composed a complete fie-cure without cutting of faults,the hydrodynamic conditions now existing in the formation under interest can by no means keep a 'hydrodynamic trap'.
