【摘要】 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。更多还原

【Abstract】 Faults and fault sealing characteristics of Bai Yanjing were studied by the analysis of interpretation of seismic profile and the study of meticulous stratigraphic correlation. Bai Yanjing oilfield seated in a special position which located in the fault development zone.There are four NNW-trending reverse faults, six near EW trending positive-strike-slip faults and reverse-strike-slip faults formed in this region, mainly including the portfolio of imbricated, washed up and hedging. The faults are in a large-scale of development, longitudinal through the layer of Yanchang and Yan’an formation. It was initially identified that faults formed after hydrocarbon accumulation, with the well fault sealing. The original reservoir are divided into a plurality of secondary reservoir, and formed a series of independent oil and gas development units.更多还原
