摘要
通过解释大量地震剖面并结合钻井资料,绘制了郭局子地区古潜山中生代构造纲要图,经详细分析认为:郭局子地区古潜山经历了印支期、燕山期和喜山期构造演化,主要发育有NWW和NNE向两组断裂,同时伴生两套与断裂近平行的褶皱;区内主要由寒武系—奥陶系地层组成,为潜山的主要储集层;寒武系—奥陶系地层内大量发育的正向小断层易使潜山内幕形成不同高度的断块油气藏。
From detailed analysis, we know that ancient buried hills in Guojuzi area have experienced Indosinian, Yanshan, and Himalayan movements, and mainly have NWW and NNE faults developed; the area mostly consists of Cambrian-Ordovician strata that act as the major reservoirs; a large number of normal faults in the strata make it possible to form fault oil-gas pools.
