Unified Correction and Connection Method of Stratigraphic Sequence with Complex Inversion
-
摘要: 在三维地质模型构建过程中，由于复杂地质构造运动形成的地层倒转、褶皱、节理等现象，传统的地层连接方法对相邻钻孔的地层对应考虑不足，从而导致三维模型地层连接不合理.针对该问题，提出一种含复杂倒转的地层层序统一修正与连接方法，引入逻辑钻孔递归统一地层层序思想，通过地层底板高程插值依据倒转地层的判别规则计算零厚度层的插入位置，统一钻孔的地层序列及修正标准地层层序，对钻孔中倒转、缺失、重复问题进行建模前的处理.通过讨论地层缺失、倒转、重复等复杂地层构造情况和实验验证，研究结果表明该方法能够充分解决零厚度层插入位置的二义性和倒转地层判定的二义性问题.该算法能够有效解决复杂地层倒转现象，为三维地质建模中地层连接提供依据.Abstract: In the process of 3D geological model construction, due to the phenomena of stratum inversion, fold and joint caused by complex geological structure movement, the traditional stratum connection method does not consider the stratum corresponding to adjacent boreholes, which leads to the 3D model construction error. According to the problem, it puts forward a kind of complex stratigraphic sequence and unified revision and connection methods, introducing logic recursive unified stratigraphic sequence of ideas, drilling through stratigraphic math discriminant rule interpolation based on reverse calculation of layer thickness of zero insertion position, so as to unify all the drilling stratigraphic sequence and the revised standard stratigraphic sequence, inverted in the borehole, loss, repeated problems for processing. The results show that this method can fully solve the ambiguity of zero thickness layer insertion position and the ambiguity of reversed formation determination through the discussion of complex formation structures such as stratum missing, inversion and duplication and experimental verification. The algorithm can effectively solve complex stratum inversion and provide scientific basis for stratum connection in 3D geological modeling.
