通过地震解释剖面分析和精细地层对比研究,对摆宴井地区断裂发育特征和断层封闭性进行了研究。摆宴井油田构造位置特殊,位于断裂带发育区,区内发育了四条NNW向展布的逆断层以及六条近EW向展布的正-走滑断层和逆-走滑断层,主要以叠瓦状、冲起及对冲组合分布,断层发育规模大,纵向贯穿延长组和延安组地层;初步认定断层形成于油气成藏之后,断层封闭性良好,将原始油藏分隔为多个次级油藏,形成独立的油气开发单元。
Through the analysis of seismic interpretation profile and the comparison of fine strata, the fault development characteristics and fault sealing in Peiyang well are studied. The pebble well field has a special tectonic position and is located in the development zone of the fault zone. There are four NNW-trending reverse faults and six near-EW trending normal-strike-slip faults and reverse strike-slip faults in the area, The facies of faults, faults and faults are well sealed, and the original reservoirs are divided into several sub-reservoirs , Forming an independent oil and gas development unit.
