Description

A method and system for determining the inter-well pumping schedule for low-yield liquid oil based on time-of-use electricity pricing Technical Field

[0001] This invention belongs to the field of oil production technology, and specifically relates to a method and system for determining the inter-well pumping regime for low-yield oil based on time-of-use electricity pricing. Background Technology

[0002] As oilfield development enters its mid-to-late stages, the number of low-yield and inefficient wells increases year by year. How to achieve efficient production from these low-yield wells has become a key issue for oilfield development. When adjusting pumping frequency cannot meet the supply and drainage coordination requirements, intermittent pumping is an effective means to improve efficiency and reduce energy consumption in low-yield wells. Traditional intermittent pumping system optimization is mostly based on changes in the dynamic fluid level. After continuous production, the dynamic fluid level falls below a certain value, and the well is shut in for a period of time to allow it to recover, keeping the dynamic fluid level within a certain range. This reduces energy consumption to some extent, but it does not fully utilize the well's production capacity. Furthermore, the pumping unit may operate at any time of day, failing to consider the impact of time-of-use electricity pricing, thus increasing additional electricity costs.

[0003] Currently, the intermittent pumping schedule is often determined based on the recovery and decline patterns of the dynamic fluid level. After a period of continuous production, the well is shut in, and the recovery of the dynamic fluid level is continuously measured. When the dynamic fluid level is low, the recovery rate is fast; as the dynamic fluid level rises, the recovery rate slows down, as shown in Figure 1. The inflection point H1 where the dynamic fluid level no longer increases is taken as the well opening height. After well opening, the decline of the dynamic fluid level is continuously measured, and the well shut-in dynamic fluid level height H2 is set. The time for the dynamic fluid level to recover from H2 to H1 during well shut-in is taken as the well shut-in time T1, and the time for the dynamic fluid level to decline from H1 to H2 is taken as the well opening production time T2. This traditional method relies on manual experience to determine the well opening and closing dynamic fluid level height and well opening and closing time, and does not provide targeted optimization for when to start pumping, resulting in high electricity costs. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a method and system for determining the intermittent pumping regime for low-yield oil wells based on time-of-use electricity pricing. This method relies on dynamic fluid level changes and optimizes the intermittent pumping regime based on the "peak-valley-flat" time-of-use electricity pricing, thereby further reducing oilfield electricity consumption.

[0005] The first objective of this invention is to provide a method for determining the inter-well pumping schedule for low-yield oil wells based on time-of-use electricity pricing, the method comprising:

[0006] Based on data on dynamic liquid level recovery and decline, the relationship between dynamic liquid level and pump efficiency and energy consumption is established.

[0007] Based on the initial intermittent pumping regime set and the relationship between dynamic liquid level and pump efficiency and energy consumption, the final intermittent pumping regime is obtained.

[0008] In some embodiments of the present invention, the dynamic liquid level recovery and descent data include curves of dynamic liquid level rise height and rise time, dynamometer diagrams or electrical parameters, and curves of dynamic liquid level descent height and descent time.

[0009] In some embodiments of the present invention, the dynamic fluid level rise height and rise time curves are obtained by measuring the dynamic fluid level height at regular intervals after production stabilizes, the well is shut in, or the dynamic fluid level remains unchanged.

[0010] In some embodiments of the present invention, the dynamometer or electrical parameters are obtained by periodically testing the dynamometer or power consumption during a fixed period; the dynamic liquid level drop height and drop time curves are obtained by periodically measuring the dynamic liquid level height within a fixed time period.

[0011] In some embodiments of the present invention, the relationship between dynamic fluid level and pump efficiency and energy consumption is established based on dynamic fluid level recovery and decline data, using interpolation, fitting, or follow-through and wellbore storage effect theoretical modeling methods.

[0012] In some embodiments of the present invention, the step of obtaining the final intermittent pumping regime based on the initial intermittent pumping regime set and the relationship between the dynamic liquid level and pump efficiency and energy consumption includes:

[0013] Based on the relationship between dynamic liquid level and pump efficiency and energy consumption, the total output and electricity cost under changes in dynamic liquid level are obtained;

[0014] Based on the total output, electricity cost set, and initial intermittent pumping regime set under the dynamic liquid level change, the final intermittent pumping regime is obtained.

[0015] A second objective of this invention is to provide a system for determining the inter-well pumping schedule for low-yield oil wells based on time-of-use electricity pricing, the system comprising:

[0016] The relationship determination module is used to obtain the total output and electricity cost set under the change of dynamic liquid level based on the relationship between dynamic liquid level and pump efficiency and energy consumption.

[0017] The final module is used to obtain the final pumping regime based on the relationship between dynamic liquid level and pump efficiency, energy consumption and initial intermittent pumping regime set.

[0018] In some embodiments of the present invention, the final module includes a first submodule and a second submodule;

[0019] The first submodule is used to obtain the total output and electricity cost set under the change of dynamic liquid level based on the relationship between dynamic liquid level and pump efficiency and energy consumption;

[0020] The second submodule is used to obtain the final intermittent pumping regime based on the total output, electricity cost set, and initial intermittent pumping regime set under the dynamic liquid level change.

[0023] The processor is configured to execute the computer program stored in the memory, so that the electronic device performs the method described above.

[0024] A fourth object of the present invention is to provide a computer-readable storage medium storing a program or instructions that, when executed on a computer, cause the computer to perform the method described above.

[0025] The beneficial effects of this invention are:

[0026] This invention provides a method and system for determining the intermittent pumping regime for low-yield oil wells based on time-of-use electricity pricing. It establishes the relationship between dynamic fluid level recovery and decline data, pump efficiency, and energy consumption, thereby obtaining the production and energy consumption set under dynamic fluid level changes. Combined with time-of-use electricity pricing, it calculates the total production and total electricity cost under different intermittent pumping regimes (total production and total electricity cost corresponding to different time segments), and selects the intermittent pumping regime scheme with high production and low electricity cost.

[0027] As can be seen, the present invention does not rely on human experience, but is determined by dynamic fluid level recovery and decline data and real-time electricity price, which not only improves the production efficiency of low-yield oil wells, but also reduces operating costs.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] As shown in Figure 2, a method for determining the inter-well pumping schedule for low-yield oil wells based on time-of-use electricity pricing according to an embodiment of the present invention includes:

[0043] Step S1: Based on the data of dynamic liquid level recovery and decline, establish the relationship between dynamic liquid level and output and energy consumption;

[0044] Step S2: Based on the initial intermittent pumping regime set and the relationship between dynamic liquid level and pump efficiency and energy consumption, the final intermittent pumping regime is obtained.

[0045] In step S1, the dynamic liquid level recovery and descent data include the dynamic liquid level rise height and rise time curve, dynamometer card or electrical parameters, and the dynamic liquid level fall height and fall time curve;

[0046] The curves of the rise height and rise time of the dynamic fluid level are obtained by measuring the dynamic fluid level height at regular intervals after production stabilizes, the well is shut in, or the dynamic fluid level remains unchanged.

[0047] The dynamometer or electrical parameters are obtained by periodically testing the dynamometer or power consumption during a fixed period, wherein the fixed period is the period from well opening to stabilization or a slowdown in the trend of change;

[0048] The dynamic fluid level drop height and drop time curves are obtained by periodically measuring the dynamic fluid level height within a fixed time period, wherein the fixed time period is from well opening to stabilization or a slowdown in the change trend;

[0049] In this embodiment of the invention, by way of example, pumping is first stopped to restore the dynamic liquid level, and the dynamic liquid level is measured every hour. Pumping is restarted after 24 hours of inactivity. When pumping is restarted, the dynamic liquid level is measured to be 1320m. The dynamic liquid level and indicator diagram are measured every hour until the dynamic liquid level is close to the pump depth, at which point pumping is stopped. After 24 hours of operation, the dynamic liquid level height is 1440m. The curves of the dynamic liquid level rise height and rise time and the curves of the dynamic liquid level fall height and fall time are obtained, i.e., the dynamic liquid level change curves are shown in Figure 3, and the obtained partial indicator diagram is shown in Figure 4.

[0050] In step S1, the relationship between the dynamic liquid level and pump efficiency and energy consumption is established based on the dynamic liquid level recovery and decline data as follows:

[0051] Pump efficiency is calculated based on the dynamometer chart set obtained above, and the power consumption during well opening is calculated and converted into daily power consumption according to the power curve set. The power consumption obtained during the test period corresponds to the dynamometer chart of the power curve.

[0052] Based on the dynamic liquid level change curve, pump efficiency and power consumption, the relationship between pump efficiency and dynamic liquid level, as well as the relationship between power consumption and dynamic liquid level, are analyzed to form the relationship curve between pump efficiency and dynamic liquid level, and the relationship curve between power consumption and dynamic liquid level, as shown in Figure 5 and Figure 6.

[0053] Then, interpolation, fitting, theoretical modeling, or other methods are used to establish the numerical relationship between the dynamic liquid level and pump efficiency and energy consumption;

[0054] In this embodiment of the invention, an interpolation method is used to establish the numerical relationship between the dynamic liquid level and the pump efficiency, and between the dynamic liquid level and the power consumption. The linear interpolation method is shown in equation (1):

[0055]

[0056] In equation (1), X represents the dynamic liquid level and Y represents the pump efficiency or power consumption.

[0057] In step S3, the process of obtaining the final intermittent pumping regime based on the initial intermittent pumping regime set and the relationship between the dynamic liquid level and pump efficiency and energy consumption includes:

[0058] Step A1: Based on the relationship between dynamic liquid level and pump efficiency and energy consumption, obtain the total output and electricity cost under the change of dynamic liquid level;

[0059] Step A2: Based on the total output, electricity cost set, and initial intermittent pumping system set under the change of dynamic liquid level, the final intermittent pumping system is obtained.

[0060] In step A1, the total output and electricity cost set under the change of dynamic liquid level, based on the relationship between dynamic liquid level and pump efficiency and energy consumption, is as follows:

[0061] Based on pump efficiency and theoretical pump displacement, the total output is obtained. The specific calculation formula is shown in equation (2):

[0062]

[0063] In equation (2), η t P is the pump efficiency at time t when the well is opened. I Where P is the theoretical displacement, T is the total well opening time, and P is the total well opening time. L Total well production;

[0064] Based on the above equation (2), and combined with the relationship between the dynamic liquid level and pump efficiency, the total output set under the change of dynamic liquid level can be obtained;

[0065] The total electricity cost is calculated based on energy consumption and time-of-use pricing. The specific calculation formula is shown in equation (3).

[0066]

[0067] In equation (3), E t Let S be the power consumption at time t. t C is the electricity cost at time t. E Total electricity cost;

[0068] Based on the above equation (3), and combined with the relationship between the dynamic liquid level and energy consumption, the total electricity cost under the change of the dynamic liquid level can be obtained;

[0069] In step A2, the final intermittent pumping rate is obtained from the total production, electricity cost set, and initial intermittent pumping rate set based on the change in dynamic liquid level, which is:

[0070] The initial time interval sampling set is a set of randomly generated time intervals or a set of conventionally generated time intervals. For example, in this embodiment of the invention, a set of randomly generated time intervals is selected, as shown below:

[0071] Intermittent pumping schedule ①: Well opening times: 0:00-7:30; 8:30-9:00; 9:30-11:30; 12:00-16:30; 17:30-18:30; 20:30-21:00; 21:30-22:30.

[0072] Intermittent pumping schedule ②: Well opening times: 0:00-7:30; 8:00-9:30; 11:00-16:00; 21:00-21:30; 22:00-24:00;

[0073] Comparing the total output and total electricity cost under each intermittent extraction scheme in the initial intermittent extraction scheme set above, the intermittent extraction scheme with high output and low electricity cost is selected as the final intermittent extraction scheme.

[0074] Specifically, the example is:

[0075] The total output and electricity cost under the dynamic liquid level change are calculated based on the specific time of the two intermittent pumping systems mentioned above, as follows:

[0076] Intermittent sampling system ①: Total output: 1.56m 3 Total electricity cost: 75 yuan / day;

[0077] Intermittent sampling system ②: Total output: 1.56m 3 Total electricity cost: 65 yuan / day;

[0078] Electricity charges are calculated according to the local time-of-use electricity price table (see Figure 7 for details).

[0079] The output of system ② is the same as that of system ①, and the electricity cost of system ② is lower than that of system ①. Therefore, system ② is superior to system ①.

[0080] The above example is merely a illustrative illustration of the process of selecting a preferred inter-instance sampling regime from the initial set of inter-instance sampling regimes. In practice, it can be obtained by comparing three or more inter-instance sampling regimes.

[0081] Therefore, by comparing total output and total electricity cost in the initial inter-yield system set, multiple preferred inter-yield systems are obtained. The intersection and combination of multiple preferred inter-yield systems form a preferred inter-yield system set. Then, by comparing total output and total electricity cost again, a more preferred inter-yield system set is generated. The comparison of total output and total electricity cost is then repeated, i.e., iterative calculation, to obtain the inter-yield system set with the lowest total electricity cost under different total outputs. The inter-yield system with high total output and low total electricity cost is selected as the operating system of the low-yield well.
