Description

Technical Field

[0001] The 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 is rich in offshore oil and gas resources. With the continuous advancement of oil and gas exploration, the development of offshore oil and gas fields has experienced a transformation from independent development of large oil and gas fields to joint development of oil field groups and then to regional development. With the continuous maturity of underground oil and gas resource networks and ground engineering facilities networks, the entire sea area may be developed as an oil field for overall research in the future. In the independent development stage and the joint development stage, the focus is on the discovered oil and gas fields. The overall oil and gas resources in the region are not fully considered. There is a lack of overall layout of engineering facilities and pipelines. The development needs of subsequent surrounding oil and gas resources are not considered. It is difficult to take into account the development of subsequent oil and gas resources, and it is impossible to achieve effective integration and sharing of engineering facilities, and it is difficult to achieve economic and effective development of offshore oil and gas fields. In comparison, new development models such as regional development and overall development not only take into account the discovered oil and gas reserves, but also take into account the development needs of future oil and gas resources, which can better achieve economic and effective 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] At present, there are relatively few studies on the conversion of resources into proven, controlled and predicted reserves. Before the regional development and overall development are proposed, the understanding of the scale of oil and gas in the trap is only to know the size of its resources. There are few studies on the scale of proven, controlled and predicted reserves that these resources can be converted into after drilling. At present, the research on resource conversion is mainly carried out around the resource discovery rate. This method can calculate the remaining unproven reserves in a basin or depression, but the scale of reserves converted in the future of each trap cannot be determined. Summary of the invention

[0004] In view of 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 purpose, 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 predicted before drilling of drilled traps in a study area; calculating the proven reserves, controlled reserves and predicted reserves of all discovered oil and gas fields in the study area according to 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 the proven reserves of oil and gas fields, the conversion rate into controlled reserves and the conversion rate into predicted reserves according to 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 to-be-drilled traps in the study area, and converting the potential geological resources of the to-be-drilled traps 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 of the drilled traps.

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

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

[0008] Furthermore, the method for calculating the conversion rate of potential geological resources of 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 of 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 of 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] Among them, R is the geological resources 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 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 closed area.

[0013] Furthermore, the area fullness prediction 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; 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; and the volume coefficient prediction value of the trap 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 to-be-drilled trap into proved geological reserves to be discovered, controlled geological reserves and predicted geological reserves is as follows: multiplying the potential geological resources of the to-be-drilled trap by the proven conversion rate of its potential geological resources to obtain proved reserves to be discovered; multiplying the potential geological resources of the to-be-drilled trap by the controlled conversion rate of the potential geological resources to obtain proved reserves to be discovered; multiplying the potential geological resources of the to-be-drilled trap by the predicted conversion rate of the 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, which is used to sum 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, which is used to calculate the proven reserve scale, controlled reserve scale and predicted reserve scale of all discovered oil and gas fields in the study area according to the sum of the potential geological resources of the drilled traps; a module for obtaining the conversion rate of drilled traps, which is used to calculate the proven reserve scale, controlled reserve scale and predicted reserve scale of all discovered oil and gas fields in the study area according to the proven reserve scale of all discovered oil and gas fields in the study area. The module calculates the conversion rate of potential geological resources in 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 module for obtaining geological reserves of traps to be tested is used to obtain the potential geological resources of traps to be drilled in the study area. Based on the conversion rate of proved reserves, controlled reserves and predicted reserves of oil and gas fields in drilled traps, the module converts the potential geological resources of traps to be drilled into proved geological reserves to be discovered, controlled geological reserves and predicted geological reserves.

[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: the present invention is based on the convenient amount of trapped resources, quickly predicts the scale of proven, controlled and predicted reserves that can be converted after future drilling of the trapped area, and serves the overall development planning of oil and gas resources.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail through specific embodiments. However, it should be understood that the provision of specific embodiments is only for a better understanding of the present invention, and they should not be understood as limitations of the present invention. In the description of the present invention, it should be understood that the terms used are only for the purpose of description and cannot be understood as indicating or implying relative importance.

[0021] In order to solve the existing demand for understanding the scale of trapped oil and gas in the prior art, it is only necessary to know the size of its resources, and there is little research on the scale of proven, controlled and predicted reserves that these resources can be converted into after drilling. The present invention proposes a prediction method, system and readable medium for converting potential geological resources of oil and gas into geological reserves of oil and gas fields, and calculates the potential geological resources of the traps to be drilled in the study area. The potential geological resources predicted before drilling in the drilled traps within the study area are counted and summed.

It can quickly and reasonably convert the trapped potential geological resources into proven, controlled and predicted geological reserves, and serve the overall development planning of oil and gas resources. The scheme of the present invention is described in detail below through embodiments in conjunction with the accompanying drawings.

[0022] Embodiment 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 in the figure, the K1 trap in the K area of ​​the study area is taken as an example to illustrate, including 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 closures in the study area is as follows: count the number and names of all the drilled closures in the study area; obtain the predicted data of the scale of the potential geological resources before drilling for all the drilled closures based on the number and names of the drilled closures; and sum the predicted data of the scale of the potential geological resources before drilling for all the drilled closures.

[0026] For areas lacking geological resource scale data, the predicted data of potential geological resources before drilling is obtained by subtracting the potential geological resources of all the traps to be drilled from the total geological resources in the study area. There are many drilled traps in the study area and the area has been explored for a long time. It is difficult to obtain the data of potential geological resources before drilling for all the drilled traps. Therefore, the total geological resources in the study area are subtracted from the potential geological resources of all the traps to be drilled to estimate the potential geological resources before drilling for all the drilled traps in the study area, and the total scale is 3.74 billion tons. The potential geological resources before drilling are shown in Table 1.

[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.

[0030] The method for calculating the conversion rate of potential geological resources of 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 of 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 of 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 are counted, and the sum of the proven geological reserves, controlled geological reserves, and predicted geological reserves of all discovered oil and gas fields is 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 are 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 of 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 reserve conversion rates of the potential geological resources. After calculation, the proved conversion rate of the 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.

[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 drilled oil and gas fields.

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

[0040]

[0041] Among them, R is the geological resource volume of the trap; 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 plane structural map; obtain the overflow point according to the seismic plane structural map and determine the location of the overflow point; draw the overflow point contour line of the trap according to the location of the overflow point; the area included in the overflow point contour line is the closed area. The plane structural map of the K1 trap was obtained through seismic interpretation, and the overflow point contour line of the K1 trap was drawn in the map. The area included in the contour line is the closed area of ​​the K1 trap, which is 2.4km 2 .

[0043] The predicted value of area fullness 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 prediction value of the trap is obtained 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 analogous oil fields is distributed between 10-50m, mainly distributed between 20-40m, and 20-40m is taken as the prediction result of the effective thickness value of the target trap.

[0045] The predicted value of trap effective porosity is obtained by analogy with the effective porosity of 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 predicted value of the oil saturation 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 value of the trap volume coefficient was obtained by analogy with the crude oil volume coefficient of surrounding oil fields. The volume coefficient was determined to be 1.093.

[0048] According to the resource calculation formula:

[0049]

[0050] Since the parameters such as area fullness, effective thickness, effective porosity, and oil saturation are obtained by analogy and have certain uncertainties, no definite values ​​are given, but only the distribution range is given. Therefore, the probability distribution of resources is obtained by using the calculation method of the closure resources based on Monte Carlo simulation, and P10, P50, P90 and Pmean can be calculated. Pmean is selected as the prediction result of the potential geological resources of the target closure. For the closure K1, the Monte Carlo simulation of the closure resources obtains its P10, P50, P90, and Pmean. The closure resources of the closure K1 take the Pmean value, which is 4.7 million cubic meters. The specific values ​​of parameters such as area fullness, effective thickness, effective porosity, and oil saturation are shown in Table 4.

[0052]

[0053] The method of converting the potential geological resources of the trap to be drilled into the proved geological reserves to be discovered, the controlled geological reserves and the predicted geological reserves is as follows: multiply the potential geological resources of the trap to be drilled by the proven conversion rate of its potential geological resources to obtain the proved reserves to be discovered; multiply the potential geological resources of the trap to be drilled by the controlled conversion rate of the potential geological resources to obtain the proved reserves to be discovered; multiply the potential geological resources of the trap to be drilled by the predicted conversion rate of the potential geological resources to obtain the proved reserves to be discovered. According to calculations, the 4.7 million cubic meters of resources in the K1 trap in the study area are expected to be converted into 3.243 million tons of proved reserves, 329,000 tons of controlled reserves and 301,000 tons of predicted reserves, as shown in Table 5.
