The prediction and research for the distribution of remaining oil in the complex fault block reservoir 复杂断块油气藏储层剩余油分布研究与预测
The study shows that good development result can be achieved with just one pattern in such reservoirs by producing with proper choke , at rational rate of oil production , and utilizing natural energy of bottom water 研究认为,对于复杂岩性多底水小断块油气藏,制定合理的油井工作制度,采用适当的采油速度,依靠底水天然能量,采取一套井网同样可以取得较好的开发效果。
On the basis of enough sources , better relations of space arrangement of oil generation , migration and reserver , good conditions of reservoirs and caprocks , subtle reservoirs are formed , such as lithological reservoirs , stratigraphic overlapping reservoirs , fault block reservoirs , palaeoburied reservoirs and fault - nose reservoirs 在油源充足,良好的生运储空间配置关系,优越的储层条件和盖层条件的基础上,形成了岩性油气藏、地层超覆油气藏、断块油气藏、古潜山油气藏和断鼻构造油气藏等多种类型的隐蔽油气藏。
