[0001] This invention relates to the field of oil and gas field development technology, and in particular to a physical simulation experiment method for evaluating high water consumption. Background Technology

[0002] The formation of high water consumption in oil fields is an inevitable and complex process. Currently, dynamic monitoring data and production data can be used in the field to determine the direction of high water consumption. Numerical simulation can use streamline simulators to describe the location, shape and range of high water consumption. Indoor physical simulation experiments can well reproduce the development process and formation law of high water consumption in the target oil reservoir, and reveal the production characteristics of different development stages of high water consumption.

[0003] Chinese invention patent CN111911135A discloses a method for dynamically describing high water-consuming zones in water-drive reservoirs. It includes the following steps: Step 1, collecting and organizing geological and development data of the target reservoir, and constructing a streamline simulation model of the target reservoir using a streamline simulator; Step 2, calling the streamline simulator to conduct streamline numerical simulation of water-drive development of the target reservoir, obtaining streamline distribution results at different times; Step 3, extracting characteristic parameter values ​​of each streamline at different times, and calculating the pseudo-water saturation of each streamline; Step 4, identifying the location and range of streamlines with pseudo-water saturation >98% at different times, and outputting the dynamic description results of high water-consuming zones in the target reservoir. This method uses a streamline simulator to construct a streamline simulation model of the target reservoir, calculates characteristic parameter values ​​of each streamline at different times, identifies the location and range of streamlines with pseudo-water saturation >98% at different times, and realizes a dynamic description of the development location, shape, and range of each high water-consuming zone in a water-drive reservoir.

[0004] Chinese invention patent CN112632864A discloses a method for identifying high water-consuming zones in oilfields using a combination of static and dynamic methods. The method includes: determining whether oil and water wells are connected; if not, determining that a high water-consuming zone does not exist; otherwise, proceeding to the next step; determining whether there is flow between oil and water wells; if not, determining that a high water-consuming zone does not exist; otherwise, proceeding to the next step; calculating the seepage resistance coefficient between oil and water wells; calculating the stratified water injection volume; and statistically analyzing the flow distribution to determine whether a high water-consuming zone exists. Using this method, the invention takes the injection well as the starting point and the production well as the ending point, studying the pathway effect between oil and water wells. It accurately, quickly, and simply identifies high water-consuming zones, aiming to salvage late-stage integrated oilfields with ultra-high water cut, accurately identify and manage high water-consuming zones, improve recovery rates, and extend the economic lifespan of ultra-high water-cut oilfields. Therefore, it has high market application value. This method determines whether oil and water wells are connected by calculating the seepage resistance coefficient and stratified water injection volume, and determines the existence of a high water-consuming zone between connected wells by statistically analyzing the flow distribution.

This method includes the following steps: characterizing geological parameters using a fuzzy comprehensive evaluation method to obtain a first potential high water-consuming zone; characterizing water saturation in the first potential high water-consuming zone using an injection-production well network, and using the water saturation abrupt change zone as the boundary to obtain a second potential high water-consuming zone; and using the fluid displacement ratio abrupt change zone as the boundary in the second potential high water-consuming zone to obtain a high water-consuming zone. This invention provides a method for identifying high water-consuming zones, offering a reference for the efficient development of water-injected oilfields. Furthermore, the three methods of this invention sequentially further determine the zone based on the previous determination, with each determination method progressively narrowing the determination range and increasing the determination accuracy, thus reducing the computational load while maintaining high computational accuracy.

This invention can quantitatively calculate the volume of the main channel in a high water-consuming strip, laying the foundation for accurately calculating the amount of plugging agent needed and providing conditions for improving the effectiveness of water injection development. This method calculates the volume of the already formed flow channel between oil and water wells by detecting the tracer's sighting time between the oil and water wells, and determines the volume of the main channel in the high water-consuming strip by comparison.

[0007] Existing methods for identifying and evaluating high water consumption mainly rely on numerical simulation, reservoir engineering calculations, and field experience. Currently, there is a lack of effective methods for evaluating high water consumption bands using indoor physical simulation experiments. These existing technologies differ significantly from our invention and fail to address the technical problem we aim to solve. Therefore, we have invented a new method for evaluating high water consumption using physical simulation experiments. Summary of the Invention

[0008] The purpose of this invention is to provide a physical simulation experiment method for evaluating high water consumption, which can be used in indoor experiments to analyze the formation and evolution of high water consumption.

[0009] The objective of this invention can be achieved through the following technical measures: a physical simulation experiment method for evaluating high water consumption, comprising:

[0010] Step 1: Based on the dynamic and static data of the target block, establish an indoor experimental simulation model of the target reservoir;

[0011] Step 2: Measure the resistance and flow rate of the electrodes in the indoor simulation model grid.

[0012] Step 3: Determine key parameters such as bound water saturation and limiting water saturation;

[0013] Step 4: Calculate the change in water saturation and the liquid production rate at different time points;

[0014] Step 5: Plot the curves showing the changes in water saturation and liquid production rate at different times;

[0015] Step 6: Based on the water saturation and the shape of the liquid production rate curve, establish the identification criteria for the formation of high water consumption zones.

[0016] The objective of this invention can also be achieved through the following technical measures:

[0017] In step 1, an indoor experimental simulation model of the target reservoir is established, including the following parameters: length, height, width, permeability, pore volume, saturated oil volume, oil phase viscosity, water phase viscosity, and displacement rate of the model core.

[0018] In step 2, an indoor simulation experiment is conducted in the target block to measure the resistance and flow rates of the electrodes in the indoor simulation model grid and verify the validity of the parameters.

[0019] In step 2, the resistance and flow rates at different locations (high-permeability, medium-permeability, and low-permeability) at the injection wellhead are measured at different time points.

[0020] In step 2, the resistance and flow rates at different locations of high-permeability, medium-permeability, and low-permeability wellheads at different time points are measured.

[0021] In step 3, the bound water saturation is the water saturation at 100% oil production at the well tip; the limiting water saturation is the water saturation at 100% water production at the well tip.

[0022] In step 4, the change in water saturation is calculated based on the resistance value.

[0023] In step 4, the resistance value measured when the water is saturated with bound water is the maximum resistance value, and the resistance value measured when the water is 100% saturated is the minimum resistance value. The variation range of water saturation at different locations and times is calculated.

[0024] In step 4, the following formula is used to calculate the variation in water saturation at different locations and times:

[0025]

[0026] Where: ΔS W -- The range of change in water saturation, a decimal; R max -- Resistance value at bound water saturation; R -- Current measured resistance value; R min -- Resistance value when 100% saturated with water.

[0027] In step 5, the correlation between water saturation and time, and between production rate and time at different locations near the oil and water wellhead are determined; curves showing the relationship between water saturation and time, and between production rate and time under different permeability conditions (high, medium, and low) are generated.

[0028] In step 6, the formation time and development stage of high water consumption are identified by the water saturation change curve, and the variation law of water saturation and produced liquid in different permeability areas is analyzed to provide guidance for mine application.

[0029] In step 6, the stage with low and stable water saturation changes is the initial stage of high water consumption, during which water content is low and production is stable; the stage with a sharp increase in water saturation changes is the growth stage of high water consumption, during which the production rate changes under different permeability, with the production rate in high-permeability areas rising rapidly and the production rate in medium and low-permeability areas decreasing to varying degrees; the stage with high and relatively stable water saturation changes is the stable stage of high water consumption, during which the production rate in different permeability areas is relatively stable, but the production of reservoirs with different permeability varies significantly.

[0030] The physical simulation experiment evaluation method for high water consumption in this invention, compared to existing technologies, adds an indoor physical experiment method for identifying high water consumption: by measuring the electrode resistance and flow rate values ​​of the model grid in the indoor experiment, the variation range of water saturation at different electrodes and different times is calculated, forming curves showing the relationship between water saturation and time, and the production rate and time under high, medium, and low permeability conditions. Based on the trend of the curves, the initial stage, growth stage, and stable stage of high water consumption are determined. The evaluation method of this invention is reliable and effective, capable of evaluating the characteristics of high water consumption in indoor physical simulation experiments and also used to guide the adjustment of scheme design during mine development. The evaluation method described in this invention can be directly used for the indoor evaluation of high water consumption in ultra-high water-cut reservoirs, and has important guiding significance for studying the formation law and management strategies of high water consumption in the later stages of high water-cut reservoirs.

[0031] Based on the dynamic and static data of the target block, an indoor experimental simulation model of the target reservoir is established. Indoor simulation experiments are conducted on the target block, measuring the resistance and flow rates of the model's grid electrodes and verifying the validity of the parameters. The values ​​of key parameters such as bound water saturation and limiting water saturation are determined. The resistance measured at bound water saturation is the maximum resistance value, and the resistance measured at 100% water saturation is the minimum resistance value. Using the formula for the variation range of water saturation, the variation range of water saturation at different electrodes and different times is calculated, forming curves showing the relationship between water saturation and time, and production rate and time under high, medium, and low permeability conditions. Based on the trend of the curves, a criterion for identifying the formation of high water-consuming zones is established. This invention's evaluation method is scientific, reliable, and highly practical. It can be directly used in indoor physical simulation experiments to identify different development stages of high water consumption, providing a reliable basis for indoor research on the development patterns and management measures of ultra-high water-cut reservoirs, facilitating more precise guidance for the efficient development of high water-cut reservoirs.

[0039] The physical simulation experiment evaluation method for high water consumption of this invention includes: establishing an indoor experimental simulation model of the target reservoir based on dynamic and static data of the target block; conducting indoor simulation experiments on the target block, measuring the resistance and flow rates of the model grid electrodes and verifying the validity of the parameters; determining the values ​​of key parameters such as bound water saturation and limiting water saturation; applying the formula for the change range of water saturation to calculate the change range of water saturation at different electrodes and different times, forming curves showing the relationship between water saturation and time, and production rate and time under different permeability conditions (high, medium, and low); and establishing identification criteria for the formation of high water consumption zones based on the trend of the curves. This evaluation method is scientifically reliable and highly practical, and can be directly used in indoor physical simulation experiments to identify various development stages of high water consumption, providing a reliable basis for indoor research on the development laws and management measures of ultra-high water-cut reservoirs.

[0040] The following are several specific embodiments of the application of the present invention.

[0041] Example 1

[0042] In a specific embodiment 1 of the present invention, such as Figure 1 As shown, Figure 1 This is a flowchart of the physical simulation experiment evaluation method for detecting high water consumption according to the present invention. The physical simulation experiment evaluation method for detecting high water consumption includes the following steps:

[0043] Step 1: Based on the dynamic and static data of the target block, establish an indoor experimental simulation model of the target reservoir. The indoor experimental simulation model of the target reservoir includes the following parameters: length, height, width, permeability, pore volume, saturated oil volume, oil phase viscosity, water phase viscosity, and displacement rate of the model core.

[0044] Step 2: Conduct indoor simulation experiments on the target block, measure the resistance and flow rates of the electrodes in the indoor simulation model grid, and verify the validity of the parameters; measure the resistance and flow rates at different time points at different locations of high-permeability, medium-permeability, and low-permeability at the injection wellhead; measure the resistance and flow rates at different time points at different locations of high-permeability, medium-permeability, and low-permeability at the oil production wellhead.

[0045] Step 3: Determine key parameters such as bound water saturation and limiting water saturation; calculate the variation range of water saturation and liquid production rate at different time points;

[0046] Determine key parameters such as bound water saturation and limiting water saturation. Bound water saturation is the water saturation at 100% oil production at the well tip; limiting water saturation is the water saturation at 100% water production at the well tip.

[0047] Calculate the variation in water saturation based on the resistance value.

[0048] The resistance value measured when the water is saturated with bound water is the maximum resistance value, and the resistance value measured when the water is 100% saturated is the minimum resistance value. The following formula is used to calculate the variation of water saturation at different locations and times (Formula 1).

[0049]

[0050] Where: ΔS W -- The range of change in water saturation, a decimal; R max -- Resistance value at bound water saturation; R -- Current measured resistance value; R min -- Resistance value when 100% saturated with water.

[0051] Step 4: Determine the correlation between water saturation and time, and production rate and time at different locations near the oil and water wellheads; generate curves showing the relationship between water cut and time, and production rate and time under different permeability conditions (high, medium, and low).

[0052] Step 5: Based on the water saturation and the shape of the liquid production rate curve, establish the identification criteria for the formation of high water consumption zones.

[0053] The formation time and development stage of high water consumption are identified by using water saturation variation curves. The variation patterns of water saturation and produced fluid in different permeability regions are analyzed to provide guidance for field applications. The stage of low and stable water saturation variation indicates the beginning of high water consumption, characterized by low water content and stable produced fluid. The stage of rapid increase in water saturation variation indicates the growth stage of high water consumption, during which the produced fluid rate changes at different permeabilities, with a rapid increase in the produced fluid rate in high-permeability regions and varying degrees of decrease in medium- and low-permeability regions. The stage of high and relatively stable water saturation variation indicates the stable stage of high water consumption, where the produced fluid rate is relatively stable across different permeability regions, but significant differences in produced fluid are observed between reservoirs with different permeabilities.

[0054] Example 2

[0055] In a specific embodiment 2 of the present invention, the physical simulation experiment method for evaluating high water consumption includes the following steps:

[0056] Step 1: Establish an indoor experimental simulation model of the target reservoir, including the following parameters: length, height, width, permeability, pore volume, saturated oil volume, oil phase viscosity, water phase viscosity, and displacement rate of the model core.

[0057] Table 1. Static Parameters of the Model (Gudong District)

[0058]

[0059] Step 2: Measure the resistance and flow rates at different locations (high, medium, and low permeability) at the injection well tip at different time points; measure the resistance and flow rates at different locations (high, medium, and low permeability) at the production well tip at different time points. Figure 2 (Diagram of injection and sampling detection).

[0060] Step 3: Determine key parameters such as bound water saturation and limiting water saturation. Bound water saturation is the water saturation when the well tip is completely filled with water, i.e., the saturation when electrodes 1-6 are all filled with water; limiting water saturation is the water saturation when the well tip produces 100% water, i.e., the saturation value when electrodes 49-54 are all filled with water.

[0061] Step 4: Calculate the change in water saturation based on the resistance value.

[0062] The resistance value measured at the bound water saturation level is the maximum resistance value, and the resistance value measured at 100% water saturation is the minimum resistance value. The following formula is used to calculate the variation range of water saturation at different locations and times (Formula 1):

[0063]

[0064] Where: ΔS W -- The range of change in water saturation, a decimal; R max -- Resistance value at bound water saturation; R -- Current measured resistance value; R min -- Resistance value at 100% saturation with water;

[0065] Step 5: Generate curves showing the relationship between water content and time, and the relationship between liquid production rate and time under different permeability conditions (high, medium, and low).

[0066] Step 6: Use the water saturation change curve to determine the formation time and development stage of high water consumption. Figure 3 This study analyzes the variation patterns of water saturation and produced fluid in different permeability zones to provide guidance for field applications. The initial stage of high water consumption is characterized by low water saturation variation and stable production. The stage of rapid increase in water saturation variation is the growth stage of high water consumption, during which the production rate varies under different permeability levels, with a rapid increase in production rate in high-permeability areas and varying degrees of decrease in medium- and low-permeability areas. The stage of high and relatively stable water saturation variation is the stable stage of high water consumption, during which the production rate in different permeability zones is relatively stable, but significant differences in production rates exist between reservoirs with different permeability levels. Figure 4-5 ).

[0067] Through case studies, in the Gudong Oilfield block, when the water saturation reaches 80%, a water-consuming zone initially forms in the high-permeability area. When the water saturation reaches 90%, the high-water-consuming zone gradually develops and stabilizes. At this point, the fluid production characteristics of different permeability areas show significant differences. During the high-water-consuming development stage, the fluid production in the high-permeability area rises rapidly to a relatively stable value, while the fluid production in the medium- and low-permeability areas gradually decreases to a similar value. When the water saturation reaches 96%, the high-water-consuming stable stage begins, and the fluid production in each permeability area remains stable, mainly due to the high-permeability area, while the medium- and low-permeability areas contribute very little to the fluid production.

[0068] Example 3

[0069] In a specific embodiment 3 of the present invention, the physical simulation experiment method for evaluating high water consumption includes the following steps:

[0070] Step 1: Establish an indoor experimental simulation model of the target reservoir, including the following parameters: length, height, width, permeability, pore volume, saturated oil volume, oil phase viscosity, water phase viscosity, and displacement rate of the model core.

[0071] Table 2 Static Parameters of the Model (Shengtuo District)

[0072]

[0073] Step 2: Measure the resistance and flow rates at different locations (high-permeability, medium-permeability, and low-permeability) at the injection wellhead at different time points; measure the resistance and flow rates at different locations (high-permeability, medium-permeability, and low-permeability) at the oil production wellhead at different time points.

[0074] Step 3: Determine key parameters such as bound water saturation and limiting water saturation. Bound water saturation is the water saturation when the well tip is completely filled with water, i.e., the saturation when electrodes 1-6 are all filled with water; limiting water saturation is the water saturation when the well tip produces 100% water, i.e., the saturation value when electrodes 49-54 are all filled with water.

[0075] Step 4: Calculate the change in water saturation based on the resistance value.

[0076] The resistance value measured at the bound water saturation level is the maximum resistance value, and the resistance value measured at 100% water saturation is the minimum resistance value. The following formula is used to calculate the variation range of water saturation at different locations and times (Formula 1):

[0077]

[0078] Where: ΔS W -- The range of change in water saturation, a decimal; R max -- Resistance value at bound water saturation; R -- Current measured resistance value; R min-- Resistance value at 100% saturation with water;

[0079] Step 5: Generate curves showing the relationship between water content and time, and the relationship between liquid production rate and time under different permeability conditions (high, medium, and low).

[0080] Step 6: Use the water saturation change curve to determine the formation time and development stage of high water consumption.

[0081] Through example calculations, in this block of Shengtuo Oilfield, when the water saturation reaches 75%, the high-permeability zone begins to form a water-consuming zone. When the water saturation reaches 88%, the high-water-consuming zone gradually develops and stabilizes. At this time, the fluid production characteristics of different permeability zones show obvious differences. In the high-water-consuming development stage, the fluid production in the high-permeability zone rises rapidly to a relatively stable value, while the fluid production in the medium- and low-permeability zones gradually decreases to a similar value. When the water saturation reaches 95.5%, it enters the high-water-consuming stable stage, and the fluid production in each permeability zone remains stable, mainly due to the high-permeability zone, while the medium- and low-permeability zones contribute very little to the fluid production.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
