摘要
泌阳凹陷北部斜坡东段复杂断鼻构造带断层发育,断裂系统复杂,断层的发育规模和连续性控制该区油气的运移、聚集和油气藏的丰度。通过对断层发育规模、连续性和油气聚集关系研究,指出该区北东向主断层的发育规模控制油藏的分布,砂体展布方向与主断层走向的配置关系控制着油气的富集程度。以此指导该区油气勘探工作,部署的泌259井试获初产自喷46方/日的高产工业油流;泌浅57区块可新增地质储量300多万吨。
The faults and fault systems are developed and complex in the northern slope region of east nose-like structure belt of Biyang sag. The develop and successive degree of fault controls the migration, accumulation and abundance degree of oil-gas reservoir. By research of the developed dimension, the successive degree of dominant fault and the relationship of oil-gas accumulation, the authors point out that developed dimension of the east-north directional dominant fault controls the distribution of oil reservoir. Matching relationship between the sand body spreading direction and the trend of dominant fault controls the abundance degree of oil-gas accumulation. And using this result guides the exploration of the region, newly defined B259 well has acquired 46 m^3 per-day high-productive oil flow; it may obtain extra 300×10~4 t newly increase oil in the place of this belt.
