[0029] Embodiment 1

[0030] Figure 1 This is a flow chart of a method for determining the source of oil and gas provided according to the first embodiment of the present invention. This embodiment is applicable to the case of determining the source of oil and gas. The method can be executed by a device for determining the source of oil and gas. The device for determining the source of oil and gas can be implemented in the form of hardware and / or software. The device for determining the source of oil and gas can be configured in a computing device. Figure 1 As shown, the method includes:

[0031] S110, obtaining state parameters corresponding to at least one oil and gas sample; the oil and gas sample contains at least three components.

[0032] The composition includes but is not limited to oil reservoir, condensate gas (also called condensate gas cap) and injected gas. The state parameters include but are not limited to temperature, pressure, mass, volume, density, formation volume coefficient, solution gas-oil ratio, viscosity, etc. Different oil and gas samples have different production attributes; production attributes include production depth and / or production location.

[0033] Specifically, representative oil and gas samples at different depths and locations of condensate gas and oil reservoirs may be selected, and actual measurement data of these oil and gas samples may be obtained, the data including state parameter information.

[0034] S120, performing phase analysis based on the state parameters, and establishing a fluid state model including a preset number of characteristic parameters.

[0035] Among them, the fluid state model includes a preset number of characteristic parameters, which can be parameters that can characterize the complex phase characteristics of the condensate gas cap + oil reservoir, for example, molecular mass MW, critical pressure Pc, critical temperature Tc, eccentricity factor Acf, volume shift coefficient Sshift, binary interaction coefficient bic, etc.

[0036] In this embodiment, the state parameters of the oil and gas samples can be substituted into the designated reservoir data simulation software, and the state equation parameters can be fitted for multiple samples at the same time, so as to establish a set of state equations representing the four-dimensional fluid phase characteristics of the oil and gas reservoir, namely, the fluid state model. When the fluid state model is applied, the oil and gas data of the oil and gas to be tested can be input into the fluid state model, and the model can output the characteristic value of each characteristic parameter, reflecting the characteristic information of the oil and gas to be tested under various parameters.

[0037] S130, determining parameter identifiers of characteristic parameters under each composition, and adjusting parameters in the fluid state model based on the characteristic parameters and parameter identifiers under each composition to generate a target state model.

[0038] The target state model includes characteristic parameters corresponding to each composition. For example, the characteristic parameter information corresponding to the three compositions of reservoir, condensate gas and injected gas in a reservoir with condensate gas cap can be found in Figure 2 Each composition contains characteristic parameters such as CO2, H2S, C1N2, C2C3, C4C5, C6-C13, C14-C29, and C30P.

[0039] In order to improve the analysis accuracy of oil and gas, the model can predict the information of each characteristic parameter corresponding to each composition. For each composition, a unique parameter identifier can be set for the corresponding characteristic parameters under different compositions, so as to adjust the parameters in the fluid state model through the parameter identifier and generate the target state equation. Optionally, the parameter identifier of each characteristic parameter under each composition is determined, including: determining the parameter identifier of each characteristic parameter under each composition based on the sorting between the compositions and the initial identifier of each characteristic parameter; or, determining the parameter identifier of each characteristic parameter under each composition based on the composition identifier of the composition and the initial identifier of each characteristic parameter. The parameter identifier is relative to the composition and the characteristic parameter, and is different from the parameter identifier of the parameter in the fluid state model. The initial identifier corresponds to the identifier of the parameter in the fluid state model.

[0040] Specifically, the parameter names of each characteristic parameter in the fluid state model can be used as initial identifiers, and the characteristic parameters under each component can be renamed according to the ranking of the three components of condensate gas, oil reservoir, and injected gas, so as to determine the parameter identifiers of each characteristic parameter under each component. For example, the initial identifier of characteristic parameter 1 in the fluid state model is CO2, the ranking of condensate gas is 1, and the parameter identifier of characteristic parameter 1 under condensate gas can be set to 1_CO2; the ranking of oil reservoir is 2, and the parameter identifier of characteristic parameter 1 under oil reservoir can be set to 2_CO2. Alternatively, the component identifier of the upper component can be assigned on the basis of the initial identifier of each characteristic parameter to generate the parameter identifier of the characteristic parameter under the component. For example, the identifier of condensate gas is C, and the parameter identifier of characteristic parameter 1 under condensate gas can be set to C_CO2; the identifier of oil reservoir is O, and the parameter identifier of characteristic parameter 1 under oil reservoir can be set to O_CO2. The parameter identifiers of the same characteristic parameter corresponding to different components are different, and the parameter identifiers of different characteristic parameters corresponding to the same component are also different, so as to distinguish the characteristic parameters under different components.

[0041] Furthermore, the name of the parameter in the fluid state model can be changed by the parameter identifier of the characteristic parameter corresponding to each composition, and the state analysis model corresponding to each characteristic parameter under each composition can be generated respectively, and each state analysis model can correspond to a characteristic parameter under one composition. Exemplarily, the original composition includes 3 and the characteristic parameters include 8, so a total of 24 state analysis models are established. Then, each state analysis model can be fused to generate a target state model.

[0042] In this embodiment, based on the characteristic parameters and parameter identifiers under each composition, the parameters in the fluid state model are adjusted to generate a target state model, including: determining the data to be used corresponding to each characteristic parameter under the same composition according to the characteristic conservation rule; based on the data to be used and the parameter identifier, the parameters in the fluid state model are adjusted to generate a target state model.

[0043] The characteristic conservation rule may be: the sum of the characteristic values ​​of all characteristic parameters under the same composition is guaranteed to be 1. The characteristic value is the data to be used.

[0044] Specifically, all characteristic parameters under the same composition can be analyzed by the characteristic conservation rule, and the data to be used corresponding to each characteristic parameter under this composition can be calculated in combination with the reservoir analysis requirements. In the process of renaming the parameters in the fluid state model using the parameter identifiers of the characteristic parameters, the parameter information or its weight can be corrected in combination with the data to be used of the characteristic parameters to generate the target state model.

[0045] For example, parameter identifiers of characteristic parameters under different compositions and an example table of data to be used of characteristic parameters can be found in Table 1. For example, the data to be used of CCO2 (parameter identifier of CO2 under condensate gas) is 0.039. The data to be used of OCO2 (parameter identifier of CO2 under oil reservoir) is 0.029.

[0050] S140: Processing the oil and gas data corresponding to the oil and gas to be tested based on the target state model to determine the oil and gas source of the oil and gas to be tested.

[0051] Among them, the source of oil and gas is one of at least three components.

[0052] Specifically, the oil and gas data corresponding to the oil and gas to be tested can be input into the target state model, and model prediction can be performed based on the target state model to obtain the oil and gas source of the oil and gas to be tested produced at the wellhead.

[0053] Optionally, the oil and gas data corresponding to the oil and gas to be tested are processed based on the target state model to determine the oil and gas source of the oil and gas to be tested, including: acquiring the oil and gas data corresponding to the oil and gas to be tested; processing the oil and gas data based on the target state model to obtain target data corresponding to each characteristic parameter under each composition; and determining the oil and gas source of the oil and gas to be tested based on the target data.

[0054] In practical applications, oil and gas data of the oil and gas to be tested can be collected, including but not limited to the oil and gas state parameters of the oil and gas itself, the geological parameters to which the oil and gas belongs, the mining parameters, etc. The target state model is used to process the oil and gas data, and the model can predict the target data corresponding to each characteristic parameter under each composition. For example, if the characteristic parameter is gas, the target data can include the content of the characteristic parameter in the composition. Furthermore, the oil and gas source of the oil and gas to be tested can be determined by the target data of each characteristic parameter under different compositions.

[0055] Optionally, based on the target data, determining the oil and gas source of the oil and gas to be tested includes: based on the target data, determining the proportion of each component from which the oil and gas to be tested originates; based on each proportion, determining the oil and gas source of the oil and gas to be tested.

[0056] Specifically, the target data of each characteristic parameter under different compositions can be used to calculate the proportion of the oil and gas to be tested originating from the condensate gas cap, dissolved gas, and injected gas, as well as the proportion of gas cap condensate in the crude oil produced from the wellhead. The composition corresponding to the maximum proportion can be used as the oil and gas source of the oil and gas to be tested, and the oil and gas flow channel can be accurately determined by the oil and gas source.

[0057] The technical solution of this embodiment is to obtain state parameters corresponding to at least one oil and gas sample; the oil and gas sample contains at least three components, including oil reservoir, condensate gas and injected gas; perform phase analysis based on the state parameters to establish a fluid state model containing a preset number of characteristic parameters; determine the parameter identifier of each characteristic parameter under each component, and adjust the parameters in the fluid state model based on each characteristic parameter and parameter identifier under each component to generate a target state model; process the oil and gas data corresponding to the oil and gas to be tested based on the target state model to determine the oil and gas source of the oil and gas to be tested, thereby solving the problem of analyzing the oil and gas source based on the content of fluid components in the prior art. In order to solve the problems of low analysis accuracy and poor effect, we have implemented phase analysis on the state parameters of multiple oil and gas samples, established a fluid state model containing a preset number of characteristic parameters, and then, on the basis of the fluid state model, adjusted the parameters in the fluid state model through the parameter identifiers of each characteristic parameter under each composition, and generated a target state model containing each characteristic parameter corresponding to each composition, so that the target state model can simultaneously simulate the data of the corresponding characteristic parameters under each composition, improve the analysis accuracy of each oil and gas composition, and then determine the oil and gas source of the oil and gas to be tested in combination with the data of the corresponding characteristic parameters under different compositions, and achieve the technical effect of accurately predicting the source of oil and gas.
