Abstract

The invention provides a continental shelf profile determination method and device based on non-delta sea invasion. The continental shelf profile determination method based on non-delta sea invasion comprises the steps of establishing a continental shelf profile two-dimensional model according to the river supply sediment volume and the sea level rising rate of a target work area; under a space rectangular coordinate system, solving the mainland profile two-dimensional model to generate a relational expression capable of representing a non-delta sea invasion gradient and a river length; and determining the continental shelf profile of the target work area according to the relational expression. According to the method and the device for determining the continental shelf section based on the non-delta sea invasion, under the background of the non-delta sea invasion, the influence of river sediment supply and sea level rise on the continental shelf section is comprehensively considered, so that the change condition of the continental shelf section in the historical period of the target work area is more accurately determined.

Description

technical field [0001] The invention relates to the technical field of petroleum and natural gas exploration and the field of marine geology, in particular to the technical field of stratum superposition pattern analysis, and in particular to a method and device for determining a continental shelf profile based on non-delta transgression. Background technique [0002] In the prior art, the calculation of the continental shelf section is based on the erosion effect of waves on the seabed. Specifically, the basic principle is that the water depth of the continental shelf gradually becomes shallower from the deep sea direction to the continental direction, and as the water depth becomes shallower, the waves affect the seabed sediments. The stronger the effect, the stronger the damage to the sediment. Sediment destroyed in shallow water will be transported to relatively deep water for deposition. This process will eventually reach an equilibrium state, in which case the section...
