Description

Technical Field

[0001] The present invention relates to the field of modeling technologies, and particularly relates to a method and system for modeling a geological model. Background Art

[0002] The piedmont zone has always been an important front for seeking breakthroughs in oil and gas exploration in China, and has always received the attention and emphasis of the exploration departments of major oil companies. Statistics show that at present, the oil resources in the piedmont zone of China are about 7.868 billion tons, 1.996 billion tons have been proven, and the proven rate is 25%; the gas resources are about 1.098 trillion cubic meters, 110 billion cubic meters have been proven, and the proven rate is 11%. It can be seen from the scale of remaining resources that the proven rate of resources in the piedmont zone of China is relatively low, and the potential for oil and gas exploration is huge.

[0003] The piedmont thrust structure can be sequentially divided into a thick-skinned belt, a transition belt, and a thin-skinned belt from the orogenic belt to the basin direction, and large-scale oil and gas are mainly distributed in the transition belt. Due to the complex tectonic deformation in the piedmont thrust belt, the quality of seismic data is generally insufficient. How to reasonably conduct structural interpretation and implement the underground structural form, geological modeling is an effective means. At present, most geological modeling work is guided by the theory of fault-related folds and is mainly carried out for the thrust belts developed in the thin-skinned belt. Most of the piedmont zones in central and western China belong to the intraplate type, with a developed transition belt and mainly characterized by basement involvement. Therefore, the existing methods are not applicable to the geological modeling of the piedmont thrust belt with a developed transition belt. Summary of the Invention

[0004] In view of this, the embodiments of the present invention provide a method and system for modeling a geological model, which solve the problem that most of the current geological modeling work is guided by the theory of fault-related folds and is mainly carried out for the thrust belts developed in the thin-skinned belt and is not applicable to the piedmont thrust belt with a developed transition belt.

Based on the formation and fault occurrence data, project the formation and fault occurrence data onto the surface elevation line according to the positions of the formation and fault occurrence data on the Global Positioning System (GPS), and at the same time, combine the formation lithological properties and the geological map to draw the surface geological measured profile.

[0071] Step S103: Obtain a structural modeling interpretation scheme based on the depth-modeled seismic profile and the measured surface geological profile.

[0073] Step S104: Modify the structural modeling interpretation scheme based on the structural deformation style and the structural deformation mode to obtain a preliminary interpretation scheme of the modeled seismic profile.

[0074] Optionally, the method for modifying the structural modeling interpretation scheme based on the structural deformation style and the structural deformation mode to obtain a preliminary interpretation scheme of the modeled seismic profile includes:

[0075] Step 1: Analyze the drilling data across the survey line or the adjacent drilling data to obtain the structural deformation pattern of the cross-well profile;

[0077] Step 3: Conduct field geological observations based on the field route, measure the structural deformation characteristics, and establish a structural deformation mode based on the structural deformation characteristics;

[0078] Step 4: Modify the deformed modeling interpretation scheme based on the structural deformation mode to obtain a preliminary interpretation scheme of the modeled seismic profile.

[0079] S105: Adjust the preliminary interpretation scheme to obtain a geological model (as Figure 6 shown).

[0080] Optionally, the adjustment of the preliminary interpretation scheme can be carried out from two aspects: physical simulation experiments and balanced profiles. Through the two methods of physical simulation experiments and balanced profiles, cycle adjustment and continuous optimization are carried out, and finally a reasonable geological model is obtained. The specific adjustment methods can refer to the following embodiments:

[0081] Optionally, adjusting the preliminary interpretation scheme through physical simulation experiments to obtain a geological model includes:

[0082] Step 1: Obtain an experimental geological model based on the preliminary interpretation scheme. Design a corresponding experimental geological model according to the preliminary interpretation scheme.

[0087] Step 2: Check the balanced cross-section based on the principle of area conservation and determine whether the balanced cross-section is balanced.

[0088] Step 3: If not, adjust the preliminary interpretation scheme. If it is determined that the balanced cross-section is balanced, the preliminary interpretation scheme is considered to meet the requirements of the final geological model; if it is determined that the balanced cross-section is unbalanced, the preliminary interpretation scheme needs to be adjusted and modified, and the structural model of the preliminary interpretation scheme is adjusted until the balanced cross-section tends to be balanced, and then the modified preliminary interpretation scheme is determined as the final geological model.

[0157] Optionally, the adjustment of the preliminary interpretation scheme can be carried out from two aspects: physical simulation experiments and balanced profiles. Through the two methods of physical simulation experiments and balanced profiles, cyclic adjustment and continuous optimization are carried out, and finally a reasonable geological model is obtained. The specific adjustment method can refer to the following embodiments:

[0158] Optionally, the physical simulation experiment adjusts the preliminary interpretation scheme to obtain a geological model, including:

[0159] Step 1: Obtain an experimental geological model based on the preliminary interpretation scheme. Design a corresponding experimental geological model according to the preliminary interpretation scheme.

[0161] Step 3: If not, adjust the preliminary interpretation scheme. Conduct a physical simulation experiment based on the experimental geological model to test the preliminary interpretation scheme, compare the experimental results of the preliminary interpretation scheme with those of the experimental geological model to obtain a comparison result, and determine whether the comparison result is within a preset range.
