为了准确地解释精细构造、研究地下的构造形态和分布,对构造图的准确度提出了更高的要求,构造图能否正确地体现地下的构造形态是识别地下构造形态的关键。本文提出用绝对值法则、“包”子原则快速判断构造图上是否存在构造陷阱。根据等值线的绝对值,在构造图上识别构造形态,找出构造高点;将得到的理论构造形态与实际的地震解释剖面对比,平、剖面相结合,验证解释结果的正确性,从而有效地识别构造陷阱。以某油田构造为例,利用法则快速区别了真假构造,剔除了构造陷阱,充分验证了法则的实用性,为快速合理地寻找圈闭提供了依据。
In order to accurately explain the fine structure, the study of the underground structure and distribution, the accuracy of the structure of the proposed higher requirements, the structure of the map can accurately reflect the subsurface structure is the key to identify the underground structure morphology. In this paper, we use the rule of absolute value and “package ” to quickly determine whether there is a structural trap on the structure graph. According to the absolute value of contours, the tectonic morphology is identified on the tectonic map and the tectonic high point is found. The obtained theoretical tectonic morphology is compared with the actual seismic interpretation profile, the flatness and profile to verify the correctness of interpretation results Identify structural traps effectively. Taking the construction of an oilfield as an example, the author uses the law to distinguish between true and false structures quickly, eliminates structural traps and fully verifies the practicability of the law, which provides a basis for quickly and rationally finding traps.
