Description

Technical Field

[0001] This invention relates to the field of oil reservoir development technology, and in particular to an automatic method, apparatus, electronic device and storage medium for layered water injection for automatic sealing verification. Background Technology

[0002] During the water injection process, there are certain differences in the lithology of different rock strata. Therefore, different water injection pressures are used for stratified water injection based on the lithology of different rock strata.

[0003] However, because the rock strata are adjacent to each other, they will affect each other during the stratified water injection process. Therefore, separating the rock strata has become one of the key aspects of stratified water injection. Existing methods often involve manually separating the rock strata and then manually verifying the separation. However, manual separation yields poor verification results and is slow. Summary of the Invention

[0004] This invention provides an automatic sealing verification method, device, electronic equipment, and storage medium for layered water injection, to solve the problem of difficulty in determining whether the sealer is in a sealed state during the layered water injection process.

[0006] Open the corresponding sealing devices for each formation in the target injection well. The sealing devices are used to divide and seal each formation.

[0007] Adjust the water distributors corresponding to the first type of formation, the second type of formation, and the third type of formation in the target injection well. The first type of formation is the formation closest to the wellhead in the target injection well. The second type of formation is the formation in the target injection well that is ranked by distance from the wellhead, and is in an odd position in the ranking result and is not a first type of formation. The third type of formation is the formation in the target injection well that is ranked by distance from the wellhead, and is in an even position in the ranking result. The water distributor is used to inject water to drive oil in the formation corresponding to that water distributor.

[0008] For each formation, determine the pressure difference between adjacent formations;

[0009] Based on the pressure difference between adjacent formations, the sealing degree of the corresponding closure device for each formation is determined.

[0010] According to another aspect of the present invention, an automatic sealing test device for layered water injection is provided, the device comprising:

[0011] The sealing device opening module is used to open the sealing devices corresponding to each formation in the target water injection well. The sealing devices are used to divide and seal each formation.

[0012] The water distributor adjustment module is used to adjust the water distributors corresponding to the first type of formation, the second type of formation, and the third type of formation in the target injection well. The first type of formation is the formation closest to the wellhead in the target injection well. The second type of formation is the formation in the target injection well that is ordered by distance from the wellhead, and is in an odd position in the sorting result and is not a first type of formation. The third type of formation is the formation in the target injection well that is ordered by distance from the wellhead, and is in an even position in the sorting result. The water distributor is used to inject water to drive oil in the formation corresponding to the water distributor.

[0013] The pressure difference determination module is used to determine the pressure difference between adjacent formations for each formation.

[0014] The sealing degree determination module is used to determine the sealing degree of the corresponding sealer for each formation based on the pressure difference between adjacent formations.

[0019] According to another aspect of the present invention, a computer-readable storage medium is provided, which stores computer instructions for causing a processor to execute and implement the layered water injection automatic sealing method of any embodiment of the present invention.

[0020] The technical solution of this invention involves opening the sealing devices corresponding to each formation within the target injection well. These sealing devices are used to divide and seal each formation. The solution also includes adjusting the water distributors corresponding to the first type of formation, the second type of formation, and the third type of formation within the target injection well. For each formation, the pressure difference between adjacent formations is determined.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0030] Example 1

[0031] Figure 1 This invention provides a flowchart of an automatic sealing verification method for layered water injection, according to Embodiment 1. This embodiment is applicable to situations where sealing verification of the seal is required during water injection in a water injection well. The method can be executed by an automatic sealing verification device for layered water injection, which can be implemented in hardware and / or software and can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0032] S110. Open the corresponding sealing devices for each formation in the target injection well. The sealing devices are used to divide and seal each formation.

[0033] See Figure 2 To facilitate understanding of the correspondence between the closure device, the water distributor, and the formation, this application uses... Figure 2 Taking this as an example, the diagram includes formation 1, formation 2, and formation 3; sealers 1, 2, and 3; and water distributors 1, 2, and 3. It should be noted that the number of formations, water distributors, and sealers is not limited to the number shown in the diagram. Figure 2 This is merely an illustrative explanation to facilitate understanding by those skilled in the art.

[0034] In the diagram, formation 1 is closest to the injection wellhead, or in other words, it is the uppermost formation. Therefore, formation 1 is a type I formation. Formation 2, after sorting formations 1, 2, and 3 according to their distance from the injection wellhead, is located in an even-numbered position, i.e., the second position, and is therefore a type III formation. Formation 3, after sorting formations 1, 2, and 3 according to their distance from the injection wellhead, is located in an odd-numbered position, i.e., the third position, and is not a type I formation; therefore, it is a type II formation.

[0035] Packer 1 and divider 2 are used to seal formation 1 and separate formation 1 from formation 2. Divider 2 and cutter 3 are used to seal formation 2 and separate formation 2 from formation 3.

[0036] Water distributor 1 is the water distributor corresponding to formation 1. It is used to inject water into formation 1 and collect information during the water injection process, including water injection pressure.

[0037] The various water distributors are connected via cables, enabling bidirectional communication, and are also connected to the ground via wired connections. A main unit on the ground controls the operation of each water distributor and collects information from them.

[0038] Before testing the sealing effect of each sealer, it is necessary to open the sealers corresponding to each formation in the target injection well, so that each formation is in a divided and sealed state.

[0039] S120, Adjust the water distributors corresponding to the first type of formation in the target injection well, the water distributors corresponding to each of the second type of formation, and the water distributors corresponding to each of the third type of formation.

[0040] The first type of formation is the formation closest to the wellhead among all formations in the target injection well; the second type of formation is the formation in the target injection well that is ranked by distance from the wellhead, and is in an odd position in the ranking result and is not a first type of formation; the third type of formation is the formation in the target injection well that is ranked by distance from the wellhead, and is in an even position in the ranking result; the water distributor is used to inject water to drive oil into the formation corresponding to the water distributor.

[0041] S130. For each formation, determine the pressure difference between adjacent formations.

[0042] See Figure 2 During water injection, if the adjacent formations 1 and 2 are connected and sealed, water injected into formation 1 will flow into formation 2. This will cause the formation pressures of formations 1 and 2 to gradually approach the same value, or the pressure difference between them to fall below a preset threshold. Furthermore, the changes in formation pressure in formations 1 and 2 will occur in the same direction; that is, if the formation pressure in formation 1 increases, the formation pressure in formation 2 will also increase, or vice versa. Since this principle applies to all formations, it can be used to determine whether the separator between formations is in a sealed state.

[0043] Therefore, the water distributors corresponding to the first type of formation, the second type of formation, and the third type of formation in the target injection well can be adjusted to show that there is a pressure difference between any adjacent formations and to determine the pressure difference between adjacent formations in each formation.

[0044] Optionally, the water distributor is also used to obtain formation pressure;

[0045] Accordingly, determining the pressure difference between adjacent formations for each stratum may include steps A1-A2:

[0046] Step A1: Obtain the formation pressure corresponding to the first, second, and third formations through each water distributor.

[0047] Step A4: Based on the formation pressure corresponding to the first type of formation, the formation pressure corresponding to each second type of formation and each third type of formation, determine the pressure difference between adjacent formations corresponding to each formation.

[0048] To obtain the formation pressure difference between different strata, the formation pressure corresponding to each type of stratum can be obtained first through the water distributor corresponding to each stratum. Then, based on the formation pressure corresponding to the first type of stratum, the formation pressure corresponding to each type of second type stratum, and the formation pressure corresponding to each type of third type stratum, the pressure difference between adjacent strata corresponding to each stratum can be determined.

[0049] S140. Based on the pressure difference between adjacent formations, determine the sealing degree of the corresponding closure device for each formation.

[0050] As explained in the principle below S130, the sealing degree of each stratum can be determined by the pressure difference between adjacent strata.

[0051] For example, see Figure 2 If the formation pressure between formation 1 and formation 2 is the same, then the seal between formation 1 and formation 2 is considered to be in a closed state.

[0052] Optionally, based on the pressure difference between adjacent formations, the sealing degree of the corresponding sealer for each formation is determined, including:

[0053] If the pressure difference between adjacent formations of the first type of formation and the target third type of formation is greater than the preset pressure difference, the seal between the first type of formation and the target third type of formation will be in a sealed state.

[0054] The target third type of stratum is the stratum adjacent to the first type of stratum.

[0055] Optionally, based on the pressure difference between adjacent formations, the sealing degree of the corresponding sealer for each formation is determined, including:

[0056] If the pressure difference between adjacent formations of the first type of formation and the target third type of formation is less than the preset pressure difference, then the sealing device between the first type of formation and the target third type of formation is in a non-sealed state.

[0057] Similarly, when judging the sealing degree of the seal, if the pressure difference between the first type of formation and the target third type of formation is less than the preset pressure difference, it indicates that the seal between the first type of formation and the target third type of formation is in a non-sealed state.

[0058] In one alternative approach, after determining the sealing degree of each formation based on the pressure difference between adjacent formations, steps B1-B2 are further included:

[0059] Step B1: Determine the surface water injection pressure; the surface water injection pressure is the water injection pressure when water is injected from the ground into the target injection well.

[0060] Step B2: If the pressure difference between the ground water injection pressure and the formation pressure corresponding to the first type of formation is greater than the preset pressure difference, the target sealer is in a sealed state.

[0061] The target sealer is used to separate the first type of formation from the surface of the target injection well.

[0062] Since the wellhead of the Type I formation is connected to the outside world, a target sealer is needed to isolate the Type I formation from the wellhead to ensure water injection efficiency during subsequent water injection. Therefore, it is necessary to determine whether the target sealer is in a sealed state.

[0063] To address this, the ground water injection pressure can be determined first. If the difference between the ground water injection pressure and the formation pressure corresponding to the first type of formation is greater than the preset pressure difference, then the target sealer is in a sealed state.

[0064] In one alternative embodiment, after the target sealer is in a sealed state if the difference between the surface water injection pressure and the formation pressure corresponding to the first type of formation is greater than a preset pressure difference, the following further step is taken:

[0065] If the pressure difference between the surface water injection pressure and the formation pressure corresponding to the first type of formation is less than the preset pressure difference, the target sealer is in a non-sealed state.

[0066] Similarly, if the pressure difference between the ground water injection pressure and the formation pressure corresponding to the first type of formation is less than the preset pressure difference, the target sealer is in a non-sealed state.

[0067] Similarly, the sealing status can also be determined using this principle for other Class II and Class III strata corresponding to their corresponding seals.

[0068] Optionally, the above steps can be automatically triggered with a single click through command integration or other methods.

[0069] According to the technical solution of the present invention, by opening the sealing devices corresponding to each formation in the target injection well, the sealing devices are used to divide and seal each formation; adjusting the water distributors corresponding to the first type of formation, the second type of formation, and the third type of formation in the target injection well; determining the pressure difference between adjacent formations for each formation; and determining the sealing degree of the sealing device corresponding to each formation based on the pressure difference between adjacent formations, automatic sealing verification of the sealing devices is realized, making the sealing verification process more accurate and efficient.

[0070] Example 2

[0071] Figure 3This invention provides a flowchart of another automatic sealing test method for stratified water injection. Based on the above embodiments, this embodiment further optimizes the process of adjusting the water distributors corresponding to the first type of formation, the second type of formation, and the third type of formation in the target injection well. This embodiment can be combined with various optional schemes in one or more of the above embodiments. Figure 3 As shown, the automatic sealing test method for layered water injection in this embodiment may include the following steps:

[0072] S210. Open the corresponding sealing devices for each formation in the target injection well. The sealing devices are used to divide and seal each formation.

[0073] S220, turn on the water distributor corresponding to the first type of formation and the water distributor corresponding to each of the second type of formations.

[0074] S230. Close the water distributors corresponding to each Class III stratum.

[0075] To ensure a sufficiently large pressure difference between adjacent formations, thus making the judgment more accurate, the water distributors corresponding to formations with odd-numbered positions in the sorting can be turned on, while those corresponding to formations with even-numbered positions can be turned off.

[0076] S240. For each formation, determine the pressure difference between adjacent formations.

[0077] S250. Based on the pressure difference between adjacent formations, determine the sealing degree of the corresponding closure device for each formation.

[0078] According to the technical solution of the present invention, by opening the water distributors corresponding to the first type of formation and the water distributors corresponding to each of the second type of formation, and closing the water distributors corresponding to each of the third type of formation, the pressure difference between adjacent formations becomes more obvious, thereby improving the accuracy of subsequent judgment results.
