Abstract
Description

[0001] This application relates to the field of carbon sequestration technology, and in particular to a method for analyzing the impact of surface deformation caused by carbon sequestration projects on wellbores. Background Technology
[0002] With the increasing severity of global climate change, carbon sequestration technology, as an important means of reducing greenhouse gas emissions, has been widely researched and applied. Carbon sequestration projects involve compressing carbon dioxide generated during industrial production and injecting it into deep geological reservoirs for long-term storage.

[0029] Figure 3 This is a schematic diagram of an electronic device according to one embodiment of this application. Detailed Implementation
[0030] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0031] Figure 1 This is a schematic diagram of an exemplary embodiment of a method for analyzing the impact of surface deformation caused by carbon sequestration projects on wellbores, as shown in this application. Figure 1 As shown, the method for analyzing the impact of surface deformation caused by carbon sequestration projects on wellbores includes the following steps:
[0032] S101, Obtain the geological parameters of the carbon sequestration area of the carbon sequestration project, and obtain the structural parameters of the wellbore to be analyzed in the sequestration area.
[0033] After obtaining the geological parameters of the carbon sequestration project's storage area, the process also includes: preprocessing the geological parameters, which includes at least cleaning (to remove outliers and noisy data) and interpolation (to supplement missing data and construct continuous parameters).
[0034] Among them, geological parameters include at least the following parameters: lithology of strata, porosity, permeability, layer thickness, groundwater level, elastic modulus and Poisson's ratio.
[0035] The structural parameters include at least the casing material, wall thickness, diameter, cement ring thickness, and bonding strength between the casing and the cement ring.
[0036] S102, based on geological and structural parameters, a three-dimensional finite element model of the wellbore is constructed using finite element analysis software.
[0037] Among them, finite element analysis software can be selected from ANSYS Mechanical APDL, ABAQUS, COMSOL Multiphysics, etc.
[0038] In the three-dimensional finite element model, boundary conditions need to be set. For example, the bottom of the model is subject to fixed constraints (limiting vertical and horizontal displacement) to simulate the constraint effect of deep stable strata; the sides of the model are subject to rolling constraints (limiting horizontal displacement but allowing vertical displacement) to simulate the lateral constraint effect of infinitely large strata.
[0039] S103: Obtain the surface deformation parameters of the storage area since carbon dioxide storage began, and simulate the stress and strain distribution of the wellbore under surface deformation in a three-dimensional finite element model based on the surface deformation parameters.
[0040] Among them, obtaining the surface deformation parameters of the storage area since the commencement of carbon dioxide sequestration includes: obtaining the surface deformation parameters of the storage area since the commencement of carbon dioxide sequestration through the Global Navigation Satellite System combined with synthetic aperture radar interferometry.
[0041] Among them, the surface deformation parameters include at least the amount of subsidence, the amount of uplift, the amount of horizontal displacement, and the deformation rate.
[0042] S104, Analysis results of the impact analysis of surface deformation caused by carbon sequestration project on wellbore based on stress and strain distribution.
[0043] The analysis results of determining the impact of surface deformation caused by carbon sequestration projects on wellbore based on stress and strain distribution include: dividing the wellbore into multiple components to be analyzed (for example, casing, wellhead, cement sheath, etc.); obtaining the stress threshold and strain threshold corresponding to each component to be analyzed, which are determined based on the material mechanical properties parameters (such as yield strength and ultimate strain) of the component to be analyzed and the safety level specifications of carbon sequestration projects; and finally, determining the impact analysis results of surface deformation caused by carbon sequestration projects on wellbore based on stress and strain distribution, combined with the stress threshold and strain threshold corresponding to each component to be analyzed.
[0044] Specifically, for any component to be analyzed, if the maximum stress of the component is determined to be greater than the corresponding stress threshold based on the stress and strain distribution, a first alarm signal is issued. For example, if the maximum stress of a component in the wellbore exceeds the corresponding stress threshold, it may cause the component to crack or rupture, thus issuing a first alarm signal.
[0045] Specifically, for any component to be analyzed, if the maximum strain of the component is determined to be greater than the corresponding strain threshold based on the stress and strain distribution, a second alarm signal is issued. For example, if the maximum strain of a component in the wellbore exceeds the corresponding strain threshold, it may cause permanent deformation of the component, thus issuing a second alarm signal.
[0046] Specifically, for any component to be analyzed, if the maximum stress of the component is greater than the corresponding stress threshold and the maximum strain is greater than the corresponding strain threshold, a third alarm signal is issued. For example, if the maximum stress of a component in the wellbore exceeds the corresponding stress threshold and the maximum strain exceeds the corresponding strain threshold, it may indicate that the component has a structural risk, and a third alarm signal will be issued.
[0047] In addition to routine risk warnings, the impact analysis results obtained above will be further applied to the optimized design and long-term safety assessment of carbon sequestration projects. Regarding optimized design, based on the stress-strain analysis results of wellbores in different areas, the carbon dioxide injection scheme will be adjusted (e.g., reducing injection pressure in areas with high wellbore stress, optimizing injection well distribution), or the wellbore structural design will be improved (e.g., selecting higher-strength casing materials, increasing cement sheath thickness) to reduce the impact of surface deformation on the wellbore from the source. Regarding long-term safety assessment, based on stress-strain simulation data from different service years, a wellbore failure probability prediction model will be established (e.g., using Monte Carlo simulation methods) to predict the failure probability of the wellbore in the next 5, 10, and 20 years. When the failure probability exceeds 1% (determined according to the safety objectives of the carbon sequestration project), a wellbore replacement or reinforcement plan will be formulated in advance to ensure the long-term safety and stability of the carbon sequestration project.
[0048] This application proposes a method for analyzing the impact of surface deformation caused by carbon sequestration projects on wellbores. The method includes: obtaining geological parameters of the carbon sequestration area and structural parameters of the wellbore to be analyzed within the sequestration area; constructing a three-dimensional finite element model of the wellbore based on the geological and structural parameters using finite element analysis software; obtaining surface deformation parameters of the sequestration area since carbon dioxide sequestration began, and simulating the stress and strain distribution of the wellbore under surface deformation in the three-dimensional finite element model based on these parameters; and determining the impact analysis results of surface deformation caused by carbon sequestration projects on the wellbore based on the stress and strain distribution.
