Description

Technical Field

[0001] This invention relates to the field of oil and gas resource evaluation technology, and in particular to a method, apparatus and equipment for determining hydrocarbon generation kinetic parameters of source rocks. Background Technology

[0002] For overseas oil and gas risk exploration, especially in areas with low exploration levels, the first scientific question is how to scientifically and accurately obtain the matching relationships between the block's oil and gas resources, source rocks, hydrocarbon expulsion history, migration and accumulation history, and various hydrocarbon accumulation conditions. Most methods for solving this problem involve geological analogy or basin (including hydrocarbon systems) simulation. The analogy method compares the basin with the main hydrocarbon accumulation geological elements of the analogous object. The selection of analogous objects based on basic geological conditions depends on the evaluator's accumulated knowledge and understanding of the basin's geological conditions.

[0003] Hydrocarbon generation kinetics of source rocks is an effective method for quantitatively simulating hydrocarbon generation or cracking processes under geological conditions. A key method within this approach is pyrolysis kinetics, which primarily studies the influence of various factors such as temperature, pressure, and reactant concentration on the rate of pyrolysis. By establishing a kinetic model of hydrocarbon generation through the thermal degradation of kerogen based on chemical kinetics theory, and combining this model with the geological background of actual sedimentary basins, it is possible to simulate the geochemical processes of hydrocarbon generation through pyrolysis of source rocks under geological conditions, as well as parameters such as the yield of sedimentary organic matter at each stage. This allows for the calculation of hydrocarbon generation in sedimentary basins and the analysis of the thermal evolution history and hydrocarbon generation and expulsion history of sedimentary basins (or hydrocarbon-bearing systems). Currently, the differences in experimental systems during source rock pyrolysis hydrocarbon generation simulation studies mainly lie in three aspects: whether the system is open or closed, whether the sample is kerogen or protolith, and whether it is anhydrous (all open systems and some closed systems) or anhydrous.

[0004] The analogy method assumes significant subjective influence and relatively large errors. The hydrocarbon generation kinetics method, based on the composition, structure, and chemical reaction kinetics of kerogen, eliminates artificial empirical parameters. Therefore, from a chemical perspective, this method undoubtedly provides a more scientific, accurate, and realistic assessment of hydrocarbon generation. However, for overseas bidding projects, conducting hydrocarbon generation simulation experiments using source rock pyrolysis presents two challenges: firstly, sampling is difficult due to objective factors (e.g., low exploration levels); secondly, the short bidding period for overseas blocks makes it difficult to resolve issues quickly. Therefore, how to scientifically and accurately evaluate project potential, support informed decision-making, and reduce investment risks is a challenge for project evaluators. Currently, global oil and gas exploration is expanding into deeper, deeper water, and unconventional areas, increasing investment risks. Summary of the Invention

[0057] Example 1

[0058] To address the technical challenges of rapidly, economically, scientifically, and accurately obtaining hydrocarbon generation kinetic parameters in areas with low exploration levels or where no source rock pyrolysis hydrocarbon generation simulation experiments have been conducted, this invention aims to develop technologies for obtaining hydrocarbon generation kinetic parameters. This will further solve the problem of obtaining hydrocarbon generation kinetic parameters from simulated source rocks in basins (including hydrocarbon systems), thus laying the foundation for scientifically evaluating the hydrocarbon generation of source rocks and simulating the five histories (geological history, thermal history, hydrocarbon generation history, hydrocarbon expulsion history, and migration and accumulation history) of basins (including hydrocarbon systems). Embodiment 1 of this invention provides a method for determining hydrocarbon generation kinetic parameters from source rocks. This method obtains hydrocarbon generation kinetic parameters from source rocks based on mathematical statistical analysis, referring to… Figure 1 As shown, the method may include the following steps:

[0059] Step S11: Based on the geological parameters of the evaluation area, select multiple experimental sample data that match the organic matter type and maturity of the evaluation area from the existing experimental data of the hydrocarbon source rock pyrolysis hydrocarbon generation model as sample calibration areas.

[0060] Step S12: Based on the pyrolysis parameters and hydrocarbon production rates of multiple sample calibration areas, construct cross-plots between the pyrolysis parameters and hydrocarbon production rates of the sample calibration areas respectively.

[0061] Step S13: Based on the pyrolysis parameters included in the geological parameters of the evaluation area and the constructed cross-plot, select the sample calibration area that matches the evaluation area from multiple sample calibration areas as the calibration area for the hydrocarbon generation kinetic parameters of the evaluation area.

[0062] Step S14: Determine the hydrocarbon generation kinetic parameters of the source rock in the evaluation area based on the calibration area of ​​the matching hydrocarbon generation kinetic parameters in the evaluation area.

[0063] The method for determining hydrocarbon generation kinetic parameters of source rocks provided in this invention is based on mathematical statistics. It obtains the hydrocarbon generation kinetic parameters (pre-index factor and activation energy) of the source rocks in the evaluation area by screening sample calibration zones, constructing pyrolysis parameters and hydrocarbon production rate charts for these zones, and determining the calibration zones. This method provides a way to scientifically and accurately obtain hydrocarbon generation kinetic parameters in areas with low exploration levels and areas where source rock pyrolysis hydrocarbon generation simulation experiments have not yet been conducted. It lays the foundation for historical simulation studies and hydrocarbon generation assessment in these areas, thus providing a basis for business and exploration decisions in these regions.

[0064] In one specific embodiment, refer to Figure 2 As shown in the figure, this invention provides a detailed method for determining hydrocarbon generation kinetic parameters of source rocks, which may include the following steps:

[0065] Step S10: Based on the basic geological conditions of the evaluation area, obtain the geological parameters of the evaluation area; wherein, the geological parameters of the evaluation area include, but are not limited to, the following geological parameters: basin type, basin tectonic evolution, geothermal gradient, source rock sampling method, source rock strata, source rock burial depth, source rock lithological assemblage, organic carbon abundance, hydrogen index, kerogen pyrolysis products, maturity, kerogen type and reservoir-seal configuration relationship.

[0066] This step involves collecting and analyzing various geological parameters of the evaluation area, especially source rock geochemical parameters, based on a thorough analysis of the basic geological conditions of the evaluation area. These parameters include, but are not limited to, basin type, basin tectonic evolution, geothermal gradient, source rock sampling method (underground (well), outcrop), source rock stratigraphy (age), source rock burial depth, source rock lithological assemblage, source rock pyrolysis parameters (if none are available, at least organic carbon abundance (TOC), hydrogen index (HI) or kerogen pyrolysis product S2, maturity Ro, and kerogen type should be collected), and reservoir-seal configuration. The more geological parameters collected and analyzed, the greater their value in the comparative analysis conducted in the following steps.

[0067] Step S11: Based on the geological parameters of the evaluation area, select multiple experimental sample data that match the organic matter type and maturity of the evaluation area from the existing experimental data of the hydrocarbon source rock pyrolysis hydrocarbon generation model as sample calibration areas.

[0068] The experimental sample data in this step are existing, directly obtainable experimental data from source rock pyrolysis hydrocarbon generation models. Research on source rock pyrolysis hydrocarbon generation kinetic models began in the 1920s, but it wasn't until the late 1960s that Tissot's parallel reaction model was applied to the calculation of hydrocarbon generation rates and quantities in certain basins. Since then, hydrocarbon generation kinetic models have been continuously improved and combined with rapidly developing computer technology, gradually becoming an important tool in source rock research and widely used in source rock evaluation, organic matter maturity, and the cracking and hydrocarbon generation of kerogen, asphaltene, and crude oil. Nearly a century of accumulated source rock pyrolysis hydrocarbon generation simulation experimental parameters provide abundant basic data, meeting the data requirements for mathematical and statistical analysis within the calibration range.

[0069] The inventors, through analysis of previous research, discovered that the type and maturity of organic matter significantly influence the activation energy of source rock for oil generation. The average activation energy increases with deteriorating organic matter type and increasing maturity. Different regions, source rock strata, and sample types have no significant impact on the average activation energy, while sample type affects the distribution of activation energy; the activation energy distribution of the original rock is more concentrated compared to kerogen. The activation energy for gas generation from mature source rocks is higher than that from less mature source rocks. Compared to open-system anhydrous pyrolysis experiments, closed-system hydropyrolysis experiments show a more concentrated activation energy distribution and can encompass both primary and secondary pyrolysis processes.

[0070] Furthermore, this step involves screening sample calibration areas based on step S10. Experimental sample data with the same or similar organic matter type and maturity as the evaluation area are selected as sample calibration areas. The more sample calibration areas there are, the greater their impact on the research. The collected, organized, and analyzed sample calibration area source rock pyrolysis hydrocarbon generation simulation experimental data are used to construct cross-plots in subsequent steps.

[0071] Step S12: Based on the pyrolysis parameters and hydrocarbon production rates of multiple sample calibration areas, construct cross-plots between the pyrolysis parameters and hydrocarbon production rates of the sample calibration areas respectively.

[0072] This step can be referred to during specific implementation. Figure 3 As shown, the specific steps include:

[0073] Step S121: Based on the pyrolysis parameters, including pyrolysis temperature and hydrocarbon production rate, in multiple sample calibration regions, construct a cross-plot between pyrolysis temperature and hydrocarbon production rate in multiple sample calibration regions.

[0074] Reference Figure 4 As shown, this step fits the pyrolysis temperature with the hydrocarbon yield (taking methane yield as an example). It is found that the slope of each curve is smaller and the curves are more concentrated in the low-temperature region; when the temperature is above 400℃, the slope gradually increases and the curves begin to disperse; when the temperature is above 500℃, the curves (…) Figure 4 (In the diagram, ①②③④⑤ represent different sample scale areas) are completely separated, and each curve exhibits a cumulative probability distribution characteristic. Figure 4 The inventors discovered that the curves could not reflect the influence of parameters such as the type and maturity of organic matter in source rocks from different sources on the differences in curve morphology.

[0075] Step S122: Based on the pyrolysis parameters including organic carbon abundance, hydrogen index and maturity, and hydrocarbon production rate in multiple sample calibration areas, construct cross-plots between organic carbon abundance and hydrocarbon production rate, hydrogen index and hydrocarbon production rate, and maturity and hydrocarbon production rate, respectively.

[0076] To address the technical problem that step S121 fails to reflect the influence of parameters such as the type and maturity of organic matter in source rocks from different sources on the differences in curve morphology, the inventors conducted further analysis. They cross-referenced parameters characterizing the organic carbon abundance (TOC), hydrogen index (HI), and maturity (Ro) of source rocks with the results of pyrolysis experiments (methane yield), and referred to... Figure 5 As shown, methane yield is positively correlated with the TOC and hydrogen index (HI) of the source rock, but the correlation is not very strong; it is negatively correlated with the maturity (Ro) of the source rock.

[0077] Step S123: Based on the cross-plots between pyrolysis temperature and hydrocarbon yield, organic carbon abundance and hydrocarbon yield, hydrogen index and hydrocarbon yield, and maturity and hydrocarbon yield, construct a cross-plot between pyrolysis parameters and hydrocarbon yield in the sample scale area.

[0078] In the specific implementation of this step, firstly, based on the correlation between hydrocarbon production rate and pyrolysis temperature, organic carbon abundance and hydrocarbon production rate, hydrogen index and hydrocarbon production rate, and maturity and hydrocarbon production rate in the cross-plot of pyrolysis temperature and hydrocarbon production rate, organic carbon abundance, hydrogen index and maturity, a comprehensive pyrolysis parameter for the sample scale area is constructed; then, based on the comprehensive pyrolysis parameter and hydrocarbon production rate of the sample scale area, a cross-plot of the comprehensive pyrolysis parameter and hydrocarbon production rate is constructed as a cross-plot of the pyrolysis parameter and hydrocarbon production rate of the sample scale area.

[0079] To address the issue of poor correlation between some source rock pyrolysis parameters and hydrocarbon yield, the inventors further analyzed the data. Based on the fact that the product of hydrogen index (HI) and total organic carbon (TOC) is the pyrolysis product of kerogen (S2), and that S2 gradually decreases with increasing source rock maturity, the inventors found a strong positive correlation between TOC × HI / Ro and methane yield, with a correlation coefficient as high as 0.922. Figure 6 It was hypothesized that TOC×HI / Ro could control the amount of methane yield. Therefore, the inventors changed the horizontal axis of the original cross-plot of methane yield (CH4) versus pyrolysis temperature (T) to TOC×HI×T / Ro (this relationship is defined as a comprehensive pyrolysis parameter, without any special geological meaning, and is only used for mathematical and statistical analysis), forming a new horizontal axis with characteristics of various source rock properties, while the vertical axis remained unchanged for methane yield. (Refer to...) Figure 7 As shown, the reintersection reveals that the pyrolysis yield curves of source rocks from different sources still exhibit the characteristics of a cumulative probability distribution, and the curves are well separated.

[0080] Step S13: Based on the pyrolysis parameters included in the geological parameters of the evaluation area and the constructed cross-plot, select the sample calibration area that matches the evaluation area from multiple sample calibration areas as the calibration area for the hydrocarbon generation kinetic parameters of the evaluation area.

[0081] In its implementation, this step first involves constructing comprehensive pyrolysis parameters for the evaluation area based on the pyrolysis parameters included in the geological parameters of the evaluation area, as well as the set initial and final pyrolysis temperatures. Then, based on these comprehensive pyrolysis parameters and cross-plots between the comprehensive pyrolysis parameters and hydrocarbon production rates constructed from multiple sample calibration areas, the hydrocarbon production rates at the initial and final pyrolysis temperatures of the evaluation area corresponding to each cross-plot are determined. Finally, based on the determined hydrocarbon production rates at the initial and final pyrolysis temperatures of the evaluation area corresponding to each cross-plot, and the hydrocarbon production rates of the sample calibration areas at the initial and final pyrolysis temperatures, a sample calibration area matching the evaluation area is selected from multiple sample calibration areas as the calibration area for the hydrocarbon generation kinetic parameters of the evaluation area.

[0082] This step involves analyzing the cross-plot of methane yield and overall pyrolysis parameters. Figure 7 As can be seen from the graph, each curve starts from the initial pyrolysis starting point A and ends at the pyrolysis completion point B. Substituting the TOC, HI, and Ro of the source rock in the evaluation area into the comprehensive pyrolysis parameter relationship, and calculating the values ​​of points A and B in the evaluation area according to the first temperature (300℃) and the second temperature (600℃) as the initial and final pyrolysis temperatures respectively, the sample calibration area closer to the values ​​of the two points is used as the calibration area for the hydrocarbon generation kinetic parameters of the evaluation area.

[0083] Step S14: Based on the calibration range of the matching hydrocarbon generation kinetic parameters for the evaluation area, determine the hydrocarbon generation kinetic parameters of the source rocks in the evaluation area. In this step, after determining the calibration range of the matching hydrocarbon generation kinetic parameters for the evaluation area, the hydrocarbon generation kinetic parameters of the source rocks in this calibration range are used as the hydrocarbon generation kinetic parameters for the evaluation area.

[0084] The detailed method for determining hydrocarbon generation kinetic parameters of source rocks provided in this embodiment of the invention addresses the technical difficulties of rapidly, economically, scientifically, and accurately obtaining hydrocarbon generation kinetic parameters in areas with low exploration levels or where hydrocarbon generation simulation experiments of source rock pyrolysis have not been carried out. It develops hydrocarbon generation kinetic parameter acquisition technology, solves the problem of obtaining hydrocarbon generation kinetic parameters of simulated source rocks in basins (including oil and gas systems), and thus lays the foundation for scientifically evaluating the hydrocarbon generation of source rocks and simulating the five histories (geological history, thermal history, hydrocarbon generation history, hydrocarbon expulsion history, and hydrocarbon migration and accumulation history) of basins (including oil and gas systems).

[0085] In a specific example, the technical solution of this embodiment will be illustrated using Basin J in a foreign country as an example:

[0086] The main source rocks in the J Basin are coal-bearing strata of the Middle and Lower Jurassic. Figure 8 As shown, the organic carbon range is 1.5%-4.4%, exhibiting a normal distribution with a peak value of 0.8%. The HI peak value is 50 mg / g TOC, and the kerogen type is type III. Based on these characteristics, refer to... Figure 9As shown, the sample calibration areas were selected from the Lower Jurassic mudstone (Type III) of the Kuqa Depression, the Middle Jurassic mudstone (Type II1) of the Southwest Tarim Depression, the Middle Jurassic mudstone (Type III) of the Chaibei Depression, the Lower Cretaceous mudstone (Type III) of the Jiuxi Basin, and the Lower Cretaceous dolomitic mudstone (Type III) of the Jiuxi Basin. Substituting the TOC, Ro, and HI values ​​of the evaluation area into the comprehensive pyrolysis parameter relationship (TOC×HI×T / Ro, pyrolysis initiation temperature is 300℃, termination temperature is 600℃), the starting point A of the abscissa was calculated to be 2.51, and the termination point B was 4.57. The starting and ending points of the methane yield curve in the J Basin are closest to the starting and ending points of the Lower Jurassic Type III mudstone curve in the Kuqa Depression (starting point A of the Kuqa Depression curve is 2.0, and B is 4.0). Figure 9 Therefore, this example establishes that the Lower Jurassic Type III mudstone source rocks in the Kuqa Depression and the Middle and Lower Jurassic source rocks in the J Basin share common characteristics. The Lower Jurassic Type III mudstone source rocks in the Kuqa Depression are selected as the study calibration area, allowing for the determination of the hydrocarbon generation kinetic parameters of the Middle and Lower Jurassic source rocks in the J Basin. Furthermore, the hydrocarbon production rate curve of the Lower Jurassic Type III mudstone source rocks in the Kuqa Depression can be used as the parameter model for this simulation study and substituted into the basin (oil and gas system) simulation software for geological model construction.

[0087] Based on the same inventive concept, Embodiment 1 of this invention also provides a device for determining hydrocarbon generation kinetic parameters of source rocks, referring to... Figure 10 As shown, the device may include: a first screening module 101, a pattern construction module 102, a second screening module 103, and a parameter determination module 104, and its working principle is as follows:

[0088] The first screening module 101 is used to select multiple experimental sample data that match the organic matter type and maturity of the evaluation area from the existing experimental data of the hydrocarbon source rock pyrolysis generation model based on the geological parameters of the evaluation area, and to use them as sample calibration areas.

[0089] The chart construction module 102 is used to construct cross-plots between pyrolysis parameters and hydrocarbon production rates of multiple sample scale areas, respectively.

[0090] The second screening module 103 is used to select the sample scale area that matches the evaluation area from multiple sample scale areas based on the pyrolysis parameters included in the geological parameters of the evaluation area and the constructed cross-plot, as the scale area for the hydrocarbon generation kinetic parameters of the evaluation area.

[0091] The parameter determination module 104 is used to determine the hydrocarbon generation kinetic parameters of the source rock in the evaluation area based on the calibration area of ​​the hydrocarbon generation kinetic parameters matched in the evaluation area.

[0095] Based on the cross-plots between pyrolysis temperature and hydrocarbon yield, organic carbon abundance and hydrocarbon yield, hydrogen index and hydrocarbon yield, and maturity and hydrocarbon yield, a cross-plot between pyrolysis parameters and hydrocarbon yield in the sample scale region is constructed.

[0096] In another optional embodiment, the drawing construction module 102 is further configured to:

[0098] Based on the comprehensive pyrolysis parameters of the sample scale area and the hydrocarbon production rate, a cross-plot of the comprehensive pyrolysis parameters and the hydrocarbon production rate is constructed as a cross-plot of the pyrolysis parameters and hydrocarbon production rate of the sample scale area.

[0099] In another alternative embodiment, the second screening module 103 is specifically used for:

[0100] Based on the pyrolysis parameters included in the geological parameters of the evaluation area, and the set starting and ending pyrolysis temperatures of the evaluation area, the comprehensive pyrolysis parameters of the evaluation area are constructed.
