Problems solved by technology

[0002] In traditional geological research, multiple methods are often used to combine and verify each other for sedimentary facies prediction, such as geology, geophysics, geochemistry, traceology methods and quantitative analysis of facies markers, so as to judge the sedimentary facies category in the area; but these The method cannot be carried out in isolation, otherwise the precision and accuracy of sedimentary facies analysis will be reduced
The cost of the existing technology is high, and the experimental process is greatly affected by human factors, which cannot be close to the real situation

Embodiment

[0123] Set the simulation area to 100m×100m (length×width), and the main parameters of the simulation area are shown in Table 1 below:

[0124] Table 1 Parameter settings of the simulation experiment

[0125]

[0126] According to Table 1, it can be seen that the simulated deposition time is one year, and the calculation time is 6-7 days. The distribution map of the sedimentary section geomorphic features at T=3500 is made by using the QUICKPLOT of Delft3D (such as Figure 4 shown) and the profile selected along the source direction (such as Figure 5Shown); the relevant profile data at T=3500 moment is exported, utilizes EXCEL to make the silt content line graph of T=3500 moment (such as figure 1 shown), the line graph of sand content 1 at T=3500 (such as figure 2 shown), the line graph of sand content 2 at time T=3500 (such as image 3 shown); the relevant section data at T=4000 moment is derived, utilize Excel to make T=3500 and T=4000 same profile sand thickness di...

Abstract

The invention discloses a sedimentary facies prediction method based on hydrodynamics. The method comprises the following steps: determining main sand control geological factors; utilizing the stratigraphic burial history for basin reconstruction; classifying sediments into two types according to different particle transportation modes; calculating a sedimentary amount of the sediments according to simulated characteristics of sedimentary components, and repeating simulation until the simulation is complete; selecting plane data of 1-4,400 moments, selecting a profile for analysis, and determining the sedimentary facies of the profile; randomly selecting a profile in the source direction or in the direction vertical to the source direction, selecting and extracting profile data, and determining the sedimentary facies of the profile based on characteristics of graphs; determining a corresponding relationship between a proportional relationship among profile components and the sedimentary facies; analyzing a corresponding relationship between a sand-mud proportion in the profile and the sedimentary facies according to the selected profile and the determined sedimentary facies of the profile; and determining the sedimentary facies of a plane. The method has the advantage that quantitative descriptions of the sedimentary facies of a sediment area can be achieved.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration and development, more specifically, it relates to a method for predicting sedimentary facies based on hydrodynamics. Background technique [0002] In traditional geological research, multiple methods are often used to combine and verify each other for sedimentary facies prediction, such as geology, geophysics, geochemistry, traceology methods and quantitative analysis of facies markers, so as to judge the sedimentary facies category in the area; but these The method cannot be carried out in isolation, otherwise the precision and accuracy of sedimentary facies analysis will be reduced. The cost of the prior art is high, and the experimental process is greatly affected by human factors, which cannot be close to the real situation. Contents of the invention [0003] The purpose of the present invention is to provide a method for predicting sedimentary facies based on hydrodynamics,...
