DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0043] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.

[0044] In order to make the technical solutions and advantages of the present application clearer, the implementation methods of the present application will be described in further detail below with reference to the accompanying drawings.

[0045] Gravity and magnetic exploration are two important methods used in the exploration of oil and gas resources. They play a vital role in the study of regional structure, basement lithology, fault distribution, local tectonic zones, buried hills, igneous rocks, and deep rifts. Furthermore, with the advancement of oil and gas exploration in my country, the exploration of igneous reservoirs has become a key area of ​​the industry. Therefore, the research, development, and innovation of interpretation and application technologies for gravity and magnetic exploration data of igneous rocks are of paramount importance.

[0046] In related technologies, relevant personnel generally manually process the gravity and magnetic exploration data of the target igneous rock. The relevant personnel estimate the grade of the target igneous rock through the gravity and magnetic exploration data, and then obtain the probability that the target igneous rock contains oil and gas resources based on the grade of the target igneous rock.

[0047] However, this manual estimation method is greatly influenced by the personal experience of relevant personnel. The grade of the target igneous rock obtained in this way has a large error, making it difficult for relevant personnel to determine the probability that the target igneous rock contains oil and gas resources based on the grade of the target igneous rock.

[0048] In order to solve the technical problems existing in the related art, the embodiment of the present application provides a grading method for target igneous rocks, which can achieve accurate grading of target igneous rocks and avoid the problem of large errors caused by manual grading in the related art.

[0049] Figure 1 This is a flow chart of a target igneous rock classification method provided in an embodiment of the present application. Figure 1 , the method comprises the following steps:

[0050] Step 101: Obtain the relationship between each target factor of the target igneous rock and its matching gravity and magnetic anomaly.

[0051] Step 102 : Based on the relationship between each target factor of the target igneous rock and its matching gravity and magnetic anomaly, determine a weight value corresponding to each target factor.

[0052] Step 103: Obtain an integral value of the target igneous rock based on the weight value corresponding to each target factor.

[0053] Step 104 : Determine the grade of the target igneous rock according to the integral grade and the integral value of the target igneous rock.

[0054] The target igneous rock classification method provided in the embodiments of this application obtains multiple target factors of the target igneous rock and, based on each target factor, determines a weighted value between the corresponding gravity and magnetic anomalies. This weighted value then determines the target igneous rock's grade based on the integrated grade and the target igneous rock's integrated value. This method achieves precise classification of the target igneous rock and avoids the large errors that occur in related techniques that use manual grading.

[0055] In some embodiments, the target factors include the following seven factors: location of igneous rocks, type of igneous rocks, structural factors, lithology of igneous rocks, fracture factors, caprock factors, and magnetic anomaly reliability.

[0056] In some embodiments, based on the relationship between each target factor of the target igneous rock and its corresponding gravity and magnetic anomaly, determining the weight value corresponding to each target factor includes:

[0057] Obtain the corresponding relationship between the factors and their matching gravity and magnetic anomalies and the weight values;

[0058] The weight value corresponding to each target factor is determined based on the relationship between the factor and its matching gravity and magnetic anomalies and the corresponding relationship between the weight values.

[0059] In some embodiments, obtaining the integral value of the target igneous rock based on the weight value corresponding to each target factor includes:

[0060] Substitute the weight value corresponding to each target factor into the target formula to calculate the integral value of the target igneous rock.

[0061] In some embodiments, when the target factors include the location of igneous rocks, the type of igneous rocks, structural factors, lithology of igneous rocks, fracture factors, caprock factors, and magnetic anomaly reliability, the target formula is:

[0062] M=M A ×(M B +M C +M D +M E +M F )×M G ;

[0063] Where M is the integral value of the target igneous rock, M A is the weight value corresponding to the location of igneous rock, M B is the weight value corresponding to the type of igneous rock, M C is the weight value corresponding to the construction factor, MD is the weight value corresponding to the lithology of igneous rock, M E is the weight value corresponding to the fracture factor, M F is the weight value corresponding to the cover factor, M G is the weight value corresponding to the magnetic anomaly reliability.

[0064] In some embodiments, before determining the grade of the target igneous rock based on the integrated grade and the integrated value of the target igneous rock, the method further includes:

[0065] Get the score level, where the score level includes multiple level intervals, and each level interval corresponds to one level.

[0066] In some embodiments, determining the grade of the target igneous rock according to the integrated grade and the integrated value of the target igneous rock includes:

[0067] Determining a grade interval of the integral value of the target igneous rock based on the integral value of the target igneous rock;

[0068] The grade of the target igneous rock is determined based on the grade interval in which the integral value of the target igneous rock falls.

[0069] Figure 2 Flow chart of another target igneous rock classification method provided in the embodiment of this application. Figure 2 , the method comprises the following steps:

[0070] Step 201: Obtain the relationship between each target factor of the target igneous rock and its matching gravity and magnetic anomaly.

[0071] It can be understood that before classifying the grade of the target igneous rock, it is necessary to obtain the relationship between each target factor related to the grade of the target igneous rock and the gravity and magnetic anomaly matched thereto.

[0072] In order to more accurately describe the target igneous rock classification method provided in the embodiment of the present application, each target factor of the target igneous rock and how these target factors are obtained based on the gravity and magnetic anomalies that match them will be described in detail below:

[0073] In some embodiments, the target factors include the following seven factors: location of igneous rocks, type of igneous rocks, structural factors, lithology of igneous rocks, fracture factors, caprock factors, and magnetic anomaly reliability.

[0074] In some embodiments, gravity and magnetic anomalies include: the low center position of the stripping residual gravity anomaly, the stripping residual gravity anomaly and the residual magnetic anomaly, the vertical secondary derivative of gravity, the lithologic gravity anomaly, the vertical first derivative of magnetism, the total horizontal gravity gradient, the burial depth of the target igneous rock, the amplitude of the polarized residual magnetic anomaly, and the total accuracy of the magnetic anomaly.

[0075] Therefore, specifically, step 201 includes:

[0076] (1) Obtain the location of the target igneous rock, where the location of the igneous rock refers to the relationship between the igneous rock and the low center position of the stripping residual gravity anomaly.

[0077] In some examples, the position of the target igneous rock, that is, the relationship between the igneous rock and the center position of the low anomaly of residual gravity of the delamination, includes: far away, relatively far, relatively close, and adjacent, wherein the length of any line connecting the center position of the low anomaly of residual gravity of the delamination and the boundary of the low anomaly of residual gravity of the delamination is set to 1, and far away, relatively far, relatively close, and adjacent refer to the intervals of [1.0, 0.7), [0.7, 0.5), [0.5, 0.2), and [0.2, 0) on any line connecting the center position of the low anomaly of residual gravity of the delamination and the boundary of the low anomaly of residual gravity of the delamination.

[0078] (2) Obtain the type of target igneous rock, where the type of igneous rock is obtained from the stripping residual gravity anomaly and residual magnetic anomaly.

[0079] In some examples, the types of igneous rocks include: small isolated volcanoes, multi-crater volcanoes, multi-stage volcanic bodies, and weathering crusts of large volcanic bodies.

[0080] (3) Obtaining the structural factors of the target igneous rock, wherein the structural factors are obtained by the vertical second derivative of gravity.

[0081] In some examples, structural factors include: structural lows, slope areas, adjacent structural highs, and structural highs.

[0082] (4) Obtaining the lithology of the target igneous rock, wherein the lithology of the igneous rock is obtained from the lithologic gravity anomaly and the vertical first derivative of the magnetic field.

[0083] In some examples, the lithology of the igneous rock includes: basic rock, intermediate basic rock, acidic rock, and intermediate acidic rock.

[0084] (5) Obtain the fracture factor of the target igneous rock, where the fracture factor is obtained by the total horizontal gravity gradient and the vertical second derivative of gravity.

[0085] In some examples, fracture factors include: no fracture (the distance between the target igneous rock boundary and the surrounding fractures is greater than 2 km), near the fracture (the distance is less than 2 km), at the fracture (the distance is less than 0.5 km), and fracture interaction zone.

[0086] (6) Obtain the cap rock factor of the target igneous rock, where the cap rock factor is the burial depth of the target igneous rock.

[0087] In some examples, the caprock factor includes intervals of less than 200 m, 201 m to 500 m, 501 m to 2000 m, 2001 m to 6000 m, 6001 m to 8000 m, and 8001 m to 10000 m.

[0088] (7) Obtain the magnetic anomaly reliability of the target igneous rock, where the magnetic anomaly reliability is the ratio of the polar residual magnetic anomaly amplitude to the total magnetic anomaly accuracy.

[0089] In some examples, the magnetic anomaly reliability is divided into four levels: less than 1.5, less than 2.5, less than 4.0, and greater than 4.0.

[0090] Step 202 : Based on the relationship between each target factor of the target igneous rock and its matching gravity and magnetic anomaly, determine the weight value corresponding to each target factor.

[0091] It is understandable that different target factors and the relationship between these different target factors and their matching gravity and magnetic anomalies have different impacts on the probability that igneous rocks contain oil and gas resources. Therefore, their importance in classifying target igneous rocks is also different, and each target factor needs to be assigned a different weight value.

[0092] In some embodiments, see Figure 3 , step 202 includes the following sub-steps:

[0093] Step 2021: Obtain the corresponding relationship between the factors and the gravity and magnetic anomalies that match them and the weight values.

[0094] In some examples, the weight of the location of igneous rocks is 0.5 to 1.0, the weight of the type of igneous rocks is 0.5 to 2.0, the weight of structural factors is 0.5 to 2.0, the weight of the lithology of igneous rocks is 1.0 to 2.0, the weight of fault factors is 0.5 to 2.0, the weight of caprock factors is 0.5 to 2.0, and the weight of magnetic anomaly reliability is 0.5 to 1.0.

[0095] Step 2022: Determine the weight value corresponding to each target factor based on the relationship between the factor and the gravity and magnetic anomalies that match it and the corresponding relationship between the weight values.

[0096] In some examples, for the locations of igneous rocks, including: far away, relatively far, relatively close, and adjacent, the corresponding weight values ​​are: 0.5, 0.7, 0.9, and 1.0, respectively.

[0097] In some examples, for the types of igneous rocks, including small independent volcanoes, multi-crater volcanoes, multi-stage volcanic bodies, and large volcanic body weathering crust, the corresponding weight values ​​are: 0.5, 1.0, 1.5, and 2.0, respectively.

[0098] In some examples, for structural factors including structural low points, slope areas, adjacent structural high points, and structural high points, the corresponding weight values ​​are: 0.5, 1.0, 1.5, and 2.0, respectively.

[0099] In some examples, the lithology of igneous rocks includes basic rock, intermediate basic rock, acidic rock, and intermediate acidic rock, and the corresponding weight values ​​are 1.0, 1.5, 1.8, and 2.0, respectively.

[0100] In some examples, for fracture factors including no fracture, near fracture, fracture site, and fracture interaction area, the corresponding weight values ​​are 0.5, 1.0, 1.5, and 2.0, respectively.

[0101] In some examples, for the cover layer factor, the intervals included are: less than 200m, 201m~500m, 501m~2000m, 2001m~6000m, 6001m~8000m, 8001m~10000m, and the corresponding weight values ​​are: 0.5, 1.0, 1.5, 2.0, 1.5, 1.0, respectively.

[0102] In some examples, the reliability of magnetic anomalies is divided into four levels: less than 1.5, less than 2.5, less than 4.0, and greater than 4.0, and the corresponding weight values ​​are: 0.5, 0.7, 0.9, and 1.0, respectively.

[0103] Step 203: Obtain the integral value of the target igneous rock based on the weight value corresponding to each target factor.

[0104] It can be understood that after obtaining the weight value corresponding to each target factor, the integral value of the target igneous rock can be obtained based on the weight value corresponding to each target factor, thereby realizing the quantitative calculation of the probability that the target igneous rock contains oil and gas resources, replacing the manual estimation method in related technologies.

[0105] In some embodiments, step 203 includes: substituting the weight value corresponding to each target factor into the target formula to calculate the integral value of the target igneous rock.

[0106] By substituting the weight value corresponding to each target factor into the target formula, the integral value of the target igneous rock is obtained, thereby replacing the manual estimation method in related technologies.

[0107] In some embodiments, when the target factors include the location of igneous rocks, the type of igneous rocks, structural factors, lithology of igneous rocks, fracture factors, caprock factors, and magnetic anomaly reliability, the target formula is:

[0108] M=M A ×(M B +MC +M D +M E +M F )×M G ;

[0109] Where M is the integral value of the target igneous rock, M A is the weight value corresponding to the location of igneous rock, M B is the weight value corresponding to the type of igneous rock, M C is the weight value corresponding to the construction factor, M D is the weight value corresponding to the lithology of igneous rock, M E is the weight value corresponding to the fracture factor, M F is the weight value corresponding to the cover factor, M G is the weight value corresponding to the magnetic anomaly reliability.

[0110] Step 204: Obtain the point level, where the point level includes multiple level intervals, and one level interval corresponds to one level.

[0111] It is understandable that before the target igneous rock is graded according to its integral value, it is necessary to first obtain the integral grade, and then grade the target igneous rock according to the grade corresponding to the integral grade.

[0112] Step 205 : Determine the grade of the target igneous rock according to the integral grade and the integral value of the target igneous rock.

[0113] In some embodiments, see Figure 4 , step 205 includes the following sub-steps:

[0114] Step 2051: Based on the integral value of the target igneous rock, determine the level interval of the integral value of the target igneous rock.

[0115] In some examples, the grade intervals are divided into 10.0-8.50, 8.49-7.0, 6.99-4.50, 4.49-2.00, and 1.99-0.0.

[0116] Step 2052: Determine the grade of the target igneous rock based on the grade interval of the integral value of the target igneous rock.

[0117] In some examples, 10.0-8.50 is the most favorable target; 8.49-7.0 is a relatively favorable target; 6.99-4.50 is a favorable target; 4.49-2.00 is a less favorable target; and 1.99-0.0 is an unfavorable target.

[0118] The grade of the target igneous rock is determined based on the obtained integral grade and the integral value of the target igneous rock calculated by the target formula, thereby replacing the method of manually estimating the grade of the target igneous rock in related technologies and achieving accurate classification of the target igneous rock.

[0119] For example, target A's integral M = MA × (MB + MC + MD + ME + MF) × MG = 1.0 × (2.0 + 2.0 + 2.0 + 1.5 + 2.0) × 1.0 = 9.5, and target B's integral M = MA × (MB + MC + MD + ME + MF) × MG = 0.9 × (1.5 + 1.5 + 1.5 + 2.0 + 2.0) × 0.9 = 6.89, then target A is determined to be the most favorable target, and target B is determined to be the favorable target.

[0120] Therefore, the target igneous rock classification method provided in the embodiments of this application obtains multiple target factors of the target igneous rock and, based on each target factor, determines the weight between the corresponding gravity and magnetic anomalies. This results in an integral value for the target igneous rock. The grade of the target igneous rock is then determined based on the integral grade and the integral value of the target igneous rock. This method achieves accurate classification of the target igneous rock and avoids the large errors that occur in the related art of using manual classification methods.
