Description

Technical Field

[0001] The present invention relates to a prediction method, system and readable medium for converting potential geological resources of oil and gas into geological reserves of oil and gas fields, belonging to the technical field of geological exploration and development of oil and gas fields. Background Art

[0002] my country's offshore oil and gas resources are abundant. With the continuous advancement of oil and gas exploration, offshore oil and gas field development has evolved from independent development of large oil and gas fields to joint development of oil field clusters and then to regional development. With the continuous maturity of underground oil and gas resource networks and surface engineering infrastructure networks, the future may see the realization of integrated development, where the entire offshore area is studied as a single oil field. During the independent and joint development phases, the focus was on discovered oil and gas fields, with insufficient consideration given to the overall oil and gas resources in the region. A comprehensive layout of engineering facilities and pipeline networks was lacking, and the subsequent development needs of surrounding oil and gas resources were not considered. This made it difficult to balance the development of subsequent oil and gas resources, effectively integrate and share engineering facilities, and achieve the economically efficient development of offshore oil and gas fields. In comparison, newer development models, such as regional development and integrated development, not only consider discovered oil and gas reserves but also future oil and gas resource development needs, and thus better achieve the economically efficient development of oil and gas fields. In regional development and overall development, a very critical task is to carry out regional resource conversion research, that is, it is necessary to predict the scale of proven reserves, controlled reserves and predicted reserves that can be converted from the current amount of enclosed geological resources.

[0003] Currently, relatively little research has focused on the conversion of resources into proved, probable, and predicted reserves. Before regional and overall development initiatives are proposed, the understanding of the scale of trapped oil and gas reserves is limited to the resource size. The ultimate conversion of these resources into proved, probable, and predicted reserves after drilling is rarely studied. Current research on resource conversion primarily focuses on the resource discovery rate, a method that can calculate the remaining unproven reserves in a basin or sag, but it is difficult to determine the future size of reserves converted from each trap. Summary of the Invention

[0004] In response to the above problems, the purpose of the present invention is to provide a prediction method, system and readable medium for converting potential geological resources of oil and gas into geological reserves of oil and gas fields, which can quickly and reasonably convert the potential geological resources of enclosed areas into proven, controlled and predicted geological reserves, and serve the overall development planning of oil and gas resources.

[0005] To achieve the above-mentioned object, the present invention proposes the following technical scheme: a prediction method for converting potential geological resources of oil and gas into geological reserves of oil and gas fields, comprising the following steps: summing the potential geological resources of drilled traps in a study area predicted before drilling; calculating the proven reserves, controlled reserves and predicted reserves of all discovered oil and gas fields in the study area based on the sum of the potential geological resources of the drilled traps; calculating the conversion rate of the potential geological resources of the drilled traps in the study area into proven reserves of oil and gas fields, the conversion rate into controlled reserves and the conversion rate into predicted reserves based on the proven reserves, controlled reserves and predicted reserves of all discovered oil and gas fields in the study area; obtaining the potential geological resources of the traps to be drilled in the study area, and converting the potential geological resources of the traps to be drilled into proven geological reserves, controlled geological reserves and predicted geological reserves to be discovered based on the proven reserves conversion rate, controlled reserves conversion rate and predicted reserves conversion rate of the oil and gas fields in the drilled traps.

[0006] Furthermore, the method for calculating the sum of the potential geological resources predicted before drilling for the drilled traps in the study area is as follows: count the number and names of all the drilled traps in the study area; obtain the predicted data of the scale of the potential geological resources before drilling for all the drilled traps based on the number and names of the drilled traps; and sum the predicted data of the scale of the potential geological resources before drilling for all the drilled traps.

[0007] Furthermore, for areas lacking geological resource scale data, the predicted data of potential geological resource scale before drilling is obtained by subtracting the potential geological resource of all traps to be drilled from the total geological resource of the study area.

[0008] Furthermore, the method for calculating the conversion rate of potential geological resources in drilled traps in the study area into proved reserves of oil and gas fields is as follows: the sum of proved reserves of discovered oil and gas fields is divided by the sum of potential geological resources of all drilled traps in the study area to obtain the conversion rate of potential geological resources into proved reserves of oil and gas fields; the method for calculating the conversion rate of potential geological resources in drilled traps in the study area into controlled reserves is as follows: the sum of controlled reserves of discovered oil and gas fields is divided by the sum of potential geological resources of all drilled traps in the study area to obtain the conversion rate of potential geological resources into controlled reserves; the method for calculating the conversion rate of potential geological resources in drilled traps in the study area into predicted reserves is as follows: the sum of predicted reserves of discovered oil and gas fields is divided by the sum of potential geological resources of all drilled traps in the study area to obtain the conversion rate of potential geological resources into predicted reserves.

[0009] Furthermore, the calculation formula for the potential geological resources of the traps to be drilled in the study area is:

[0010]

[0011] Where R is the geological resource of the trap; S is the closed area of ​​the trap; r is the area filling coefficient; H is the effective thickness; is the effective porosity; So is the oil saturation; B is the volume coefficient.

[0012] Furthermore, the method for obtaining the closed area of ​​the trap is: collecting seismic data to generate a seismic plane structural map; obtaining overflow points in the seismic plane structural map and determining the positions of the overflow points; drawing the overflow point contour lines of the trap according to the positions of the overflow points; the area included in the overflow point contour lines is the trap area.

[0013] Furthermore, the area fillness prediction value is determined based on a comprehensive analysis of the oil and gas sources, the height of the oil reservoirs in the surrounding drilled oil and gas fields, and the type, amplitude and effectiveness of the traps. The effective thickness prediction value of the trap is obtained by analogy with the effective thickness distribution of the drilled wells in the surrounding oil fields. The effective porosity prediction value of the trap is obtained by analogy with the effective porosity of the surrounding oil fields. The oil saturation prediction value of the trap is obtained by analogy with the oil saturation of the surrounding oil fields. The trap volume coefficient prediction value is obtained by analogy with the crude oil volume coefficient of the surrounding oil fields.

[0014] Furthermore, the method for converting the potential geological resources of the trap to be drilled into proved geological reserves to be discovered, controlled geological reserves and predicted geological reserves is as follows: multiplying the potential geological resources of the trap to be drilled by the proven conversion rate of its potential geological resources to obtain proved reserves to be discovered; multiplying the potential geological resources of the trap to be drilled by the controlled conversion rate of potential geological resources to obtain proved reserves to be discovered; and multiplying the potential geological resources of the trap to be drilled by the predicted conversion rate of potential geological resources to obtain proved reserves to be discovered.

[0015] The present invention also discloses a prediction system for converting potential geological resources of oil and gas into geological reserves of oil and gas fields, comprising: a module for obtaining geological resources of drilled traps, for summing up the potential geological resources predicted before drilling of the drilled traps in the study area; a module for obtaining the reserve scale of drilled traps, for calculating the proven reserve scale, controlled reserve scale and predicted reserve scale of all discovered oil and gas fields in the study area based on the sum of the potential geological resources of the drilled traps; a module for obtaining the conversion rate of drilled traps, for calculating the proven reserve scale, controlled reserve scale and predicted reserve scale of all discovered oil and gas fields in the study area based on the proven reserve scale of all discovered oil and gas fields in the study area; and a module for obtaining the conversion rate of drilled traps, for calculating the proven reserve scale, controlled reserve scale and predicted reserve scale of all discovered oil and gas fields in the study area based on the proven reserve scale of all discovered oil and gas fields in the study area. The module is used to calculate the potential geological resources of the drilled traps in the study area, the proved reserves scale, the controlled reserves scale and the predicted reserves scale, and respectively calculate the conversion rate of the potential geological resources of the drilled traps in the study area into proved reserves of oil and gas fields, the conversion rate into controlled reserves and the conversion rate into predicted reserves; the geological reserves acquisition module for the traps to be tested is used to obtain the potential geological resources of the traps to be drilled in the study area, and based on the proved reserves conversion rate, controlled reserves conversion rate and predicted reserves conversion rate of the oil and gas fields of the drilled traps, convert the potential geological resources of the traps to be drilled into proved geological reserves to be discovered, controlled geological reserves and predicted geological reserves to be discovered.

[0016] The present invention also discloses a computer-readable storage medium having a computer program stored thereon. The computer program is executed by a processor to implement any of the above-mentioned methods for predicting the conversion of potential geological resources of oil and gas into geological reserves of oil and gas fields.

[0017] The technical solution of the present invention has at least the following technical effects or advantages: Based on the convenient measurement of trapped resources, the present invention rapidly predicts the scale of proven, probable, and predicted reserves that can be converted from trapped resources after future drilling, thus serving the overall development planning of oil and gas resources. By utilizing historical regularity analysis, the present invention can rapidly convert trapped potential geological resources into proven, probable, and predicted reserves, thus serving the development planning of oil and gas resources.

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail through specific embodiments. However, it should be understood that the specific embodiments are provided only for a better understanding of the present invention and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms used are for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] To address the existing need for understanding the scale of trapped oil and gas resources, which in the prior art only requires knowledge of the resource size, but rarely studies the scale of proven, probable, and predicted reserves that can ultimately be converted from these resources after drilling. The present invention proposes a prediction method, system, and readable medium for converting potential oil and gas geological resources into oil and gas field geological reserves. The method calculates the potential geological resources of traps to be drilled within a study area. The pre-drilling predicted potential geological resources of drilled traps within the study area are calculated and summed. The proven reserves, probable reserves, and predicted reserves of all discovered oil and gas fields within the study area are calculated. The conversion rates of potential geological resources of drilled traps in the study area into proven reserves, probable reserves, and predicted reserves of oil and gas fields are calculated. Based on the calculated conversion rates of potential geological resources into proven reserves, potential resources into probable reserves, and potential resources into predicted reserves for drilled traps, the potential geological resources of the traps to be drilled are converted into proven geological reserves, probable geological reserves, and predicted geological reserves to be discovered. It can quickly and reasonably convert trapped potential geological resources into proven, controlled and predicted geological reserves, serving the overall development planning of oil and gas resources. The present invention is described in detail below through embodiments in conjunction with the accompanying drawings.

[0022] Example 1

[0023] This embodiment discloses a method for predicting the conversion of potential geological resources of oil and gas into geological reserves of oil and gas fields. Figure 1 As shown, the K1 trap in the K area of ​​the study area is taken as an example to illustrate, which includes the following steps:

[0024] S1 sums the potential geological resources predicted before drilling for the drilled traps in the study area.

[0025] The method for calculating the sum of the potential geological resources predicted before drilling for the drilled traps in the study area is as follows: count the number and names of all the drilled traps in the study area; obtain the predicted data of the scale of the potential geological resources before drilling for all the drilled traps based on the number and names of the drilled traps; and sum the predicted data of the scale of the potential geological resources before drilling for all the drilled traps.

[0026] For areas lacking geological resource data, pre-drilling potential geological resources were estimated by subtracting the potential geological resources of all remaining traps from the total geological resources in the study area. Given the large number of drilled traps in the study area and the extensive exploration history, pre-drilling potential geological resources for all drilled traps are difficult to obtain. Therefore, the pre-drilling potential geological resources for all drilled traps in the study area were estimated by subtracting the potential geological resources of all remaining traps from the total geological resources in the study area. The total pre-drilling potential geological resources are shown in Table 1.

[0027] Table 1. Potential geological resources before drilling in the K area

[0028] area Total potential resources, billion tons K 37.4

[0029] S2 calculates the proven reserves, controlled reserves and predicted reserves of all discovered oil and gas fields in the study area based on the potential geological resources of the drilled traps and the total reserves.

[0030] The method for calculating the conversion rate of potential geological resources in drilled traps in the study area into proved reserves of oil and gas fields is as follows: the sum of proved reserves of discovered oil and gas fields is divided by the sum of potential geological resources of all drilled traps in the study area to obtain the conversion rate of potential geological resources into proved reserves of oil and gas fields; the method for calculating the conversion rate of potential geological resources in drilled traps in the study area into controlled reserves is as follows: the sum of controlled reserves of discovered oil and gas fields is divided by the sum of potential geological resources of all drilled traps in the study area to obtain the conversion rate of potential geological resources into controlled reserves; the method for calculating the conversion rate of potential geological resources in drilled traps in the study area into predicted reserves is as follows: the sum of predicted reserves of discovered oil and gas fields is divided by the sum of potential geological resources of all drilled traps in the study area to obtain the conversion rate of potential geological resources into predicted reserves.

[0031] Based on the latest reserve table, the proven, controlled, and predicted geological reserves of all discovered oil and gas fields were counted, and the sum of the proven geological reserves, controlled geological reserves, and predicted geological reserves of all discovered oil and gas fields was calculated. After statistical calculation, the proven geological reserves, controlled geological reserves, and predicted geological reserves of the discovered oil and gas fields in the study area were 2.58 billion tons, 260 million tons, and 240 million tons, respectively, as shown in Table 2.

[0032] Table 2K Regional Oil and Gas Field Proven, Controlled, and Predicted Reserves

[0033]

[0034] S3 calculates the conversion rate of potential geological resources in the drilled traps in the study area into proved reserves of oil and gas fields, the conversion rate into controlled reserves, and the conversion rate into predicted reserves based on the proven reserves, controlled reserves, and predicted reserves of all discovered oil and gas fields in the study area.

[0035] The total proved geological reserves, total controlled geological reserves, and total predicted geological reserves in the study area were divided by the sum of the potential geological resources of all drilled traps to obtain the proved reserves, controlled reserves, and predicted reserves conversion rates of potential geological resources. After calculation, the proved conversion rate of potential geological resources in the study area was 69.0%, the controlled conversion rate was 7.0%, and the predicted conversion rate was 6.4%, as shown in Table 3.

[0036] Table 3 K area potential geological resource conversion rate data table

[0037]

[0038] S4 obtains the potential geological resources of the traps to be drilled in the study area, and converts the potential geological resources of the traps to be drilled into proved geological reserves to be discovered, controlled geological reserves and predicted geological reserves based on the proven reserve conversion rate, controlled geological reserves conversion rate and predicted geological reserves conversion rate of the oil and gas fields that have been drilled.

[0039] The calculation formula for the potential geological resources of the traps to be drilled in the study area is:

[0040]

[0041] Where R is the trapped geological resources; S is the closed area of ​​the trap; r is the area filling coefficient; H is the effective thickness; φ is the effective porosity; So is the oil saturation; and B is the volume coefficient.

[0042] The method for obtaining the closed area of ​​the trap is as follows: collect seismic data and generate a seismic planar structural map; obtain the overflow points from the seismic planar structural map and determine their locations; draw contour lines of the overflow points based on their locations; and the area encompassed by the contour lines of the overflow points is the closed area. Seismic interpretation yielded a planar structural map of the K1 trap, on which contour lines of the overflow points of the K1 trap were drawn. The area encompassed by the contour lines is the closed area of ​​the K1 trap, which is 2.4 km. 2 .

[0043] The predicted area fullness value is determined based on a comprehensive analysis of the oil and gas sources, the height of the surrounding drilled oil and gas fields, the type, amplitude and effectiveness of the traps. After analysis, it is found that the area fullness of the K1 trap is distributed between 30-50%.

[0044] The effective thickness of the trap is predicted by analogy with the effective thickness distribution of wells drilled in surrounding oil fields; Figure 2 As shown in the figure, N1, N2 and N3 are the names of oil fields. The effective thickness of the analogy oil fields is distributed between 10-50m, mainly distributed between 20-40m. 20-40m is taken as the prediction result of the effective thickness value of the target trap.

[0045] The predicted value of the effective porosity of the trap is obtained by analogy with the effective porosity of the surrounding oil fields. The porosity distribution range of the analog oil fields is 10-40%, and its porosity is mainly distributed in 30-35%. 30-35% is selected as the predicted result of the effective porosity of the target trap.

[0046] The oil saturation prediction value of the trap is obtained by analogy with the oil saturation of the surrounding oil fields. The oil saturation of the analog oil fields is mainly distributed between 50-60%, so the oil saturation of the target trap K1 is also mainly distributed between 50-60%.

[0047] The predicted trap volume coefficient was obtained by analogy with crude oil volume coefficients in surrounding oil fields. The volume coefficient was determined to be 1.093.

[0048] According to the resource calculation formula:

[0049]

[0050] Because parameters such as areal fill, effective thickness, effective porosity, and oil saturation are derived through analogy and have a certain degree of uncertainty, definite values ​​are not given, only distribution ranges. Therefore, a Monte Carlo simulation-based trap resource calculation method was used to determine the probability distribution of resources, and P10, P50, P90, and Pmean were calculated. Pmean was selected as the prediction of the potential geological resources of the target trap. For trap K1, Monte Carlo simulation of the trap resources yielded its P10, P50, P90, and Pmean. The Pmean value for trap K1 was 4.7 million cubic meters. Specific values ​​for parameters such as areal fill, effective thickness, effective porosity, and oil saturation are shown in Table 4.

[0052]

[0053] The method for converting the potential geological resources of a trap to be drilled into proved geological reserves, probable geological reserves, and predicted geological reserves is as follows: multiply the potential geological resources of a trap to be drilled by its proven conversion rate to obtain proved reserves; multiply the potential geological resources of a trap to be drilled by its probable conversion rate to obtain proved reserves; and multiply the potential geological resources of a trap to be drilled by its probable conversion rate to obtain proved reserves. Calculations show that the 4.7 million cubic meters of resources in the K1 trap in the study area can be converted into 3.243 million tons of proved reserves, 329,000 tons of probable reserves, and 301,000 tons of predicted reserves, as shown in Table 5.
