[0019] Step S102: Acquire N sampling points included in the horizontal well, where N is an integer greater than or equal to 1.

[0020] Optionally, the N sampling points included in the horizontal well can be obtained through the following steps: determine the location and size of the horizontal well through geological exploration and measurement data; determine the interval of the sampling points based on the size of the horizontal well and the sampling requirements. Generally, the interval of the sampling points should be small enough to capture changes in the formation; select appropriate tools or technologies, such as core drilling, logging tools and seismic measurement technology, for sampling based on the interval of the sampling points to obtain the N sampling points included in the horizontal well.

[0021] Step S104, obtaining lithology parameters, physical property parameters, and oil content parameters corresponding to the N sampling points, wherein the lithology parameters are used to indicate the rock characteristics in the reservoirs corresponding to the N sampling points, the physical property parameters are used to indicate the physical characteristics corresponding to the N sampling points, and the oil content parameters are used to indicate the reservoir characteristics in the reservoirs corresponding to the N sampling points.

[0022] Optionally, lithology parameters refer to parameters that describe the characteristics of rock type, structure, composition, etc., such as rock type, pore structure, shale content, etc.; physical parameters refer to parameters that describe the physical properties of rocks, such as density, acoustic wave velocity, porosity, permeability, resistivity, etc.; oil content parameters refer to parameters that describe the oil and gas content and distribution in rocks, such as oil saturation, crude oil American Petroleum Institute (API) gravity, etc. These parameters can be used to evaluate the rock properties, physical properties and oil and gas content corresponding to each sampling point in the horizontal well, and then guide oil and gas development and production.

[0023] In an optional embodiment, a three-dimensional model is performed on the target area where the horizontal well is located to obtain a lithology model, a physical property model, and an oil content model of the target area, wherein the lithology model is used to indicate the rock characteristics in the reservoir in the target area, the physical property model is used to indicate the physical characteristics of the target area, and the oil content model is used to indicate the reservoir characteristics in the reservoir in the target area; based on the lithology model of the target area, the lithology parameters corresponding to N sampling points are determined; based on the physical property model of the target area, the physical property parameters corresponding to N sampling points are determined; based on the oil content model of the target area, the oil content parameters corresponding to N sampling points are determined.

[0024] Optionally, geological modeling software, digital twin technology or deep learning technology can be used to perform three-dimensional modeling of the target area where the horizontal well is located to obtain the lithology model, physical property model and oil content model of the target area. The three-dimensional coordinates of the N sampling points are respectively brought into the lithology model to obtain the lithology parameters corresponding to the N sampling points, the three-dimensional coordinates of the N sampling points are respectively brought into the physical property model to obtain the physical property parameters corresponding to the N sampling points, and the three-dimensional coordinates of the N sampling points are respectively brought into the oil content model to obtain the oil content parameters corresponding to the N sampling points. By performing three-dimensional geological modeling on the area where the horizontal well is located, the geological information of the area where the horizontal well is located can be presented in a three-dimensional form, including the distribution of lithology, physical properties and oil content, and the geological information of each sampling point can be accurately and detailedly obtained.

[0025] Step S106: determining attenuation functions corresponding to the N sampling points respectively, wherein the attenuation functions are used to indicate attenuation changes of the three-dimensional coordinates corresponding to the N sampling points respectively.

[0026] Optionally, the attenuation function is used to indicate the attenuation change of the three-dimensional coordinates corresponding to N sampling points within the fracturing range. By obtaining the attenuation functions corresponding to the N sampling points, it can help evaluate the fracturing effect and improve the efficiency of oil and gas production.

[0027] In an optional embodiment, determining the attenuation functions corresponding to the N sampling points respectively includes: obtaining the three-dimensional coordinates of the wellbore in the horizontal well, and the three-dimensional coordinates corresponding to the N sampling points respectively; determining the fracturing ranges corresponding to the N sampling points respectively based on the three-dimensional coordinates of the wellbore and the three-dimensional coordinates corresponding to the N sampling points respectively; determining the attenuation functions corresponding to the N sampling points respectively based on the three-dimensional coordinates of the wellbore, the three-dimensional coordinates corresponding to the N sampling points respectively, and the fracturing ranges corresponding to the N sampling points respectively.

[0028] Optionally, fracturing is a technology that releases underground natural gas or oil by injecting high-pressure liquid to form cracks in rocks. The reachable range of fracturing refers to the range that liquid or gas can affect after fracturing operations are performed in underground rock formations. The reachable range of fracturing is usually limited and depends on multiple factors, including underground rock properties, pressure and volume of injected liquid, expansibility of rock cracks, etc. The reachable range of fracturing corresponding to each of the N sampling points can be obtained by the three-dimensional coordinates of the wellbore and the three-dimensional coordinates corresponding to each of the N sampling points. Based on the three-dimensional coordinates of the wellbore, the three-dimensional coordinates corresponding to each of the N sampling points, and the reachable range of fracturing corresponding to each of the N sampling points, the attenuation functions corresponding to each of the N sampling points can be obtained.

[0029] In an optional embodiment, based on the three-dimensional coordinates of the wellbore and the three-dimensional coordinates corresponding to the N sampling points, respectively, the fracturing range corresponding to the N sampling points is determined, including: based on the three-dimensional coordinates of the wellbore and the three-dimensional coordinates corresponding to the N sampling points, the fracturing range corresponding to any one of the N sampling points is determined in the following manner:

[0031] Among them, r is the fracturing range corresponding to any sampling point; x is the geodetic latitude corresponding to any sampling point; y is the geodetic longitude corresponding to any sampling point; z is the altitude corresponding to any sampling point; x0 is the geodetic latitude of the wellbore; y0 is the geodetic longitude of the wellbore; z0 is the altitude of the wellbore; a is the major semi-axis of the fracturing ellipse; b is the minor semi-axis of the fracturing ellipse.

[0032] Optionally, the affected area of ​​​​the fracturing is elliptical in shape, wherein the major semi-axis represents the length of the major axis of the ellipse, and the minor semi-axis represents the length of the minor axis of the ellipse. The shape of the ellipse represents the range of diffusion of the fracturing fluid or fracturing gas in the rock formation, and the size of the major semi-axis and the minor semi-axis directly affects the effect and range of the fracturing operation.

[0033] In an optional embodiment, based on the three-dimensional coordinates of the wellbore, the three-dimensional coordinates corresponding to the N sampling points, and the fracturing ranges corresponding to the N sampling points, determining the attenuation functions corresponding to the N sampling points respectively includes: based on the three-dimensional coordinates of the wellbore, the three-dimensional coordinates corresponding to the N sampling points, and the fracturing ranges corresponding to the N sampling points respectively, determining the attenuation function corresponding to any one of the N sampling points in the following manner:

[0037] Optionally, the geological quality assessment results of the horizontal well can be determined by the lithological parameters, physical parameters, oil content parameters, and attenuation functions corresponding to the N sampling points. The obtained geological quality assessment results can quantitatively characterize the sweet spots in the vertical and horizontal directions, which is helpful to achieve accurate fracturing and improve reserve utilization. If the horizontal well is interpreted as an oil layer, if the geological quality is good, it will reveal that the wellbore and the surrounding oil layers are developed, and the scale of transformation can be appropriately increased to obtain better development results; if the horizontal well is interpreted as a dry layer or mudstone, if the geological quality is good, it will reveal that although the horizontal well has not been drilled in the oil layer, the oil layer is developed within the range of the well, and it has the material basis for through-layer fracturing; if the horizontal well is interpreted as an oil layer, if the geological quality is average, it will reveal that the horizontal well is drilled in a thin oil layer, and the surrounding oil layer is not developed, and the construction countermeasures should be mainly horizontal transformation.

[0038] In an optional embodiment, the geological quality assessment result of the horizontal well is determined based on the lithological parameters, physical parameters, oil content parameters, and attenuation functions respectively corresponding to the N sampling points, including: determining the geological quality assessment results corresponding to the N sampling points based on the lithological parameters, physical parameters, oil content parameters, and attenuation functions respectively corresponding to the N sampling points; determining the geological quality assessment result of the horizontal well based on the geological quality assessment results corresponding to the N sampling points.

[0039] Optionally, the geological quality assessment results corresponding to the N sampling points can be obtained through the lithological parameters, physical parameters, oil content parameters, and attenuation functions corresponding to the N sampling points. Based on the geological quality assessment results corresponding to the N sampling points, the geological quality assessment results of the areas corresponding to the N sampling points in the horizontal well can be determined. For example, if the geological quality assessment result of sampling point a is high and the geological quality assessment result of sampling point b is low, it means that the geological quality of area A corresponding to sampling point a in the horizontal well is good, and the geological quality of area B corresponding to sampling point b is poor. Alternatively, based on the geological quality assessment results corresponding to the N sampling points, the geological quality assessment results of the horizontal well can be finally determined by weighted summation, averaging, etc. By determining the geological quality assessment results of the horizontal well based on the geological quality assessment results of each sampling point, the geological quality assessment results of each sampling point can be fully considered, thereby improving the accuracy of the geological quality assessment results of the horizontal well.

[0040] In an optional embodiment, based on the lithological parameters, physical parameters, oil content parameters, and attenuation functions corresponding to the N sampling points, determining the geological quality assessment results corresponding to the N sampling points respectively includes: based on the lithological parameters, physical parameters, oil content parameters, and attenuation functions corresponding to the N sampling points respectively, determining the geological quality assessment result corresponding to any one of the N sampling points in the following manner:

[0043] Optionally, GQ is a one-dimensional attribute of the sand body thickness, lithology, physical properties, oil content and relative position of the wellbore in the fracturing wave space per unit wellbore length, which realizes the conversion from three-dimensional data to one-dimensional data and simplifies the quantitative characteristic evaluation results of the three-dimensional sweet spot of the horizontal well.

[0044] Through the above steps S102 to S108, the purpose of accurately determining the geological quality assessment result of the horizontal well based on the lithological parameters, physical parameters, oil content parameters, and attenuation function corresponding to the N sampling points in the horizontal well can be achieved, thereby achieving the technical effect of improving the accuracy of the geological quality assessment of the horizontal well, and further solving the technical problem of low accuracy of the quantitative characteristic assessment of the three-dimensional sweet spot of the horizontal well caused by incomplete consideration of factors when conducting the quantitative characteristic assessment of the three-dimensional sweet spot of the horizontal well in the related technology.

Category A is a dominant sweet spot segment, where a sweet spot refers to a geological area with high production capacity and economic benefits. This type of sweet spot is interpreted as an oil layer by well logging, with good geological quality, and is greater than 0.6 overall, revealing that the horizontal well is drilled in the oil layer, and the oil layer around the well is well developed. The scale of transformation should be increased to obtain better development results.

The logging interpretation of this type of sweet spot is poor oil layer and dry layer.
