随着勘探程度的逐渐提高,储量小,构造幅度低且被断层复杂化的油气藏所占的比例逐年上升,储量品位日趋下降,低幅度构造的勘探逐渐受到重视,编制高精度的构造图是该类构造勘探的一个核心环节。从理论上分析了分辨率和构造成图精度的关系,探讨了在解释阶段研究低幅度构造的可行性及其思路和方法,以达到在资料分辨率基本许可的条件下,利用解释工作方法与技术的改进对低幅度构造进行研究和分析,而不仅仅依赖于高成本重新处理的目的。

The number of low amplitude hydrocarbon reservoirs discovered is climbing as exploration goes into depth. The key to detect this kind of reservoirs is to draw up a high precision structure map. Based on a theoretical analysis of the relationship between resolution and precision of drawing, this paper discussed the feasibility and methods to study the low amplitude structures during data interpretation.
