摘要
廊固凹陷大兴断裂潜山带历经20多年的论证,进一步开展高精度重力、磁力、电法、地震全信息地球物探综合研究分析认为,其是一个断垒式潜山。对大兴断裂潜山带的成藏条件进行了精细分析,发现大兴潜山具有良好的油源条件;多方向供油,供油窗口大;潜山由南而北依次出现高于庄组、雾迷山组地层,储层为厚层白云岩;叠前储层预测潜山缝洞发育,具有明显的含油气特征,有利于油气富集。廊固凹陷大兴断裂潜山带具有较大的勘探潜力。
Daxing fracture buried hill of Langgu Sag has gone through arguments for more than 20years.For further development with high-precision gravity,magnetic,electrical,seismic information of earth geophysical interpretation,which is considered to be a broken horst buried hill.This study is based on the fine analysis of reservoir conditions in Daxing fracture buried hill,which indicates that the Daxing buried hill has favorable conditions of source with multi-directional oil and big oil window.From south to north the stratigraphy turns from Gaoyuzhuang Formation to Wumishan Formation.The reservoir is thick-bedded dolomite.Prestack reservoir forecast is that the buried hill fissure cave is developmental.With obvious hydrocarbon characteristics and conductivity to the accumulation of oil and gas.The study points out that Daxing fracture buried hill of Langgu Sag has great exploration potential.
