Embodiment Construction
[0019] The main idea of the present invention is that, based on high-resolution sequence stratigraphy, oil layer division and correlation units are determined by dividing different order cycles and an isochronous sequence correlation framework is established. The medium-term base level cycle corresponds to the division of oil groups; the short-term The base-level cycle corresponds to the division of sand formations; according to the established sequence stratigraphic framework, sub-layers are divided and compared under the control of cycles and stratigraphic superimposition patterns, which can effectively avoid the time-traveling phenomenon that often occurs in the process of oil layer correlation.
[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] According to an embodiment of ...
