通过开展地质、地震综合研究,建立了南堡凹陷馆陶组火山喷发模式与岩相模式;通过研究南堡凹陷特殊的断裂样式,建立了南堡凹陷火山成因断裂模式.在以上两种地质模式指导下,开展了火山口位置识别和断裂精细解释,新解释了21个火山口,利用能量相位复合属性刻画火成岩分布,准确预测了南堡1号构造中浅层的火成岩分布.研究结果表明:研究区火山口主要分布在南堡1号断裂附近,馆陶组火成岩厚度100~500m之间,南厚北薄,西厚东薄,主力油层区均分布在厚层火成岩之下,为该区有利储层分布预测、油气成藏规律分析和地质储量动用打下坚实基础.
Through comprehensive geological and seismic studies, the volcanic eruption pattern and facies model of Guantao Formation in Nanpu Sag have been established, and the volcanic genesis fault pattern of Nanpu Sag has been established by studying the special fault pattern in Nanpu Sag.In the above two geological models Under the guidance of a detailed description of the crater location identification and fracture, a new interpretation of the 21 volcanoes, the use of energy phase composite properties of igneous rock distribution, accurate prediction of the structure of the Nanpu No. 1 igneous igneous rock distribution.The results show that: The volcano crater in the study area is mainly distributed near the fault No. 1 in Nanpu. The volcanic rocks of Guantao Formation have a thickness of 100-500m, with thin thick anomalies in the south and north and thin in the east and thick in the main reservoirs, Favorable reservoir distribution forecasting, hydrocarbon accumulation law analysis and utilization of geological reserves, laying a solid foundation.
