Description

Technical Field

[0001] This invention relates to the field of oilfield stratified water injection technology, and in particular to a pulse width adaptive wireless communication method, device, electronic device and medium. Background Technology

[0002] Petroleum is an indispensable strategic resource for national survival and development. Waterflooding is the main development method for oilfields in my country, with 80% of domestic production coming from waterflooding. The effectiveness of waterflooding directly affects national energy security. Domestic oilfields generally have multi-layered and heterogeneous characteristics. Indiscriminate waterflooding can lead to single-layer surges. Therefore, the widespread adoption of stratified waterflooding is a key and effective means to improve waterflood recovery rates.

[0003] To further improve the effectiveness of stratified water injection, China has developed fourth-generation stratified water injection technology. Its core feature is the ability to continuously monitor downhole stratified parameters and automatically control stratified flow rates. Currently, there are two main technical routes for fourth-generation stratified water injection: one is the cable-controlled route, where downhole parameters are transmitted to the surface via a pre-installed cable outside the tubing; the other is the wavecode wireless route, where downhole parameters are transmitted to the surface wirelessly. Compared to the cable-controlled method, the cableless method has advantages such as simpler construction and lower cost, and can be used for pressurized operations. The process principle is illustrated below. Figure 1 As shown. The existing wavecode communication injection process achieves bidirectional communication by using a wellhead communication controller to generate pressure changes with the water distributors at each downhole level through switching valves.

[0004] Existing wireless communication technology for water injection wells uses the same pulse width for encoding and communication. The bidirectional wireless communication process between each layer and the wellhead is affected by the characteristics of the current formation and other formations, resulting in low communication efficiency and poor reliability. Figure 1 The following is an example of a conventional wavecode communication layered water injection process: Assume a water injection well has n layers. When data from any layer (let's say the second layer) needs to be transmitted, the second layer's water distributor's electrically controlled valve actively switches on and off, causing a change in tubing pressure. The wellhead communication controller receives the pressure wave change signal and decodes it to obtain the downhole data. However, different reservoir water absorption characteristics will result in different pressure changes during the communication process. For some layers, due to the influence of other layers' water absorption characteristics (e.g., strong water absorption), the wellhead pressure wave change amplitude may be small and difficult to identify, affecting communication reliability; or the pressure wave change time may be long (e.g., weak water absorption), leading to low communication efficiency. Summary of the Invention

[0005] This invention provides a pulse width adaptive wireless communication method, device, electronic equipment, and medium. By using a water distributor for self-testing, it achieves pulse width adaptation for communication at each layer, improving the communication efficiency and reliability of each layer of wavecode wireless communication, thereby maximizing the efficiency of whole-well wireless communication.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0031] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. 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. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0032] Example 1

[0033] Figure 2 This is a flowchart of a pulse-width adaptive wireless communication method according to Embodiment 1 of the present invention. This embodiment is applicable to situations where communication pulse widths are set for each segment in a wireless stratified water injection process. The method can be executed by a pulse-width adaptive wireless communication device, which can be implemented in hardware and / or software and can be configured within a device. For example, the device can be a backend server or other device with communication and computing capabilities. Figure 2 As shown, the method includes:

[0034] S210. Determine the target layer in the wireless layered water injection process.

[0035] In this scheme, the wireless stratified water injection process consists of n layers, each layer consisting of a packer and a water distributor. It can achieve two-way communication with the water distributors of each layer downhole through the switching valves of the wellhead communication controller to generate pressure changes. Figure 3 This is a schematic diagram of successful decoding of a 3-second pulse width provided in Embodiment 1 of this application, as shown below. Figure 3 As shown, for layers with good water absorption, the pressure difference generated by the downhole high-efficiency switch is large, for example, above 1 MPa. At this time, the surface can achieve decoding with a pulse width of 3 seconds, maximizing the communication efficiency of the current layer. Figure 4This is a schematic diagram of successful decoding of a 10-second pulse width provided in Embodiment 1 of this application, as shown below. Figure 4 As shown, for layers with poor water absorption, the pressure difference generated by the downhole high-efficiency switch is small, for example, below 0.3 MPa. Decoding can only be achieved on the test surface with a pulse width of 10-15 seconds, ensuring reliable and efficient decoding of layers with small pressure differences. That is, different layers have different communication capabilities. Therefore, different pulse widths can be adaptively applied to the different pressure difference conditions of each layer, maximizing the communication efficiency potential of each layer while ensuring communication reliability, thereby improving the overall well wireless communication efficiency.

[0036] In this embodiment, Figure 5 This is the downhole data wireless upload encoding method provided in Embodiment 1 of this application, such as... Figure 5 As shown, wireless communication commonly uses time-based encoding. The switching time of the downhole signal generator is 1.5 seconds. The distance between the start of the switching action and the next action is the pulse width of the communication. The shorter the pulse width, the faster the transmission speed. However, the shorter the pulse width, the shorter the pressure rise amplitude.

[0037] In this scheme, the target layer can refer to any layer in the wireless layered water injection process. Preferably, each layer in the wireless layered water injection process can be used as the target layer for communication pulse width setting. That is, the target layer can be the nth layer in the wireless layered water injection process. Preferably, the layer with relatively good water absorption can be used as the target layer.

[0038] S220: Control the on / off valve of the target layer water distributor to operate fully open and fully close, and obtain the pressure change value of the oil pipe in the wireless stratified water injection process.

[0039] In this plan, Figure 6 This is the layered water injection pulse width adaptive wireless communication process provided in Embodiment 1 of this application, such as... Figure 6 As shown, the target layer water distributor performs a self-test before wireless communication. Specifically, the switch valve of the nth layer water distributor is controlled to operate fully open and fully closed. The oil pipe pressure value when the switch valve of the nth layer water distributor is fully open is recorded, and the oil pipe pressure value when the switch valve of the nth layer water distributor is fully closed is also recorded, thereby determining the oil pipe pressure change value.

[0040] Optionally, the on / off valve of the target layer water distributor is controlled to operate fully open and fully closed to obtain the pressure change value of the oil pipe in the wireless stratified water injection process, including:

[0041] The on / off valve of the target layer water distributor is controlled to operate fully open and fully closed, and the pressure change value of the oil pipe in the wireless stratified water injection process is recorded based on the pressure sensor.

[0042] In this scheme, when the switch valve of the target layer water distributor is fully open or fully closed, the pressure change value of the oil pipe in the wireless stratified water injection process can be recorded based on the pre-installed pressure sensor.

[0043] By recording the pressure change values ​​of the tubing in the wireless stratified water injection process, the communication pulse width of each layer can be adaptively adjusted based on the pressure change values, which improves the communication efficiency and reliability of each layer of the wavecode wireless communication, thereby maximizing the efficiency of whole-well wireless communication.

[0044] Optionally, when controlling the on / off valve of the target layer water distributor to operate fully open or fully closed, the on / off valves of other layer water distributors in the wireless stratified water injection process are controlled to maintain a constant valve opening; wherein, other layer water distributors are used to characterize the remaining layer water distributors in the wireless stratified water injection process other than the target layer water distributor.

[0045] In this scheme, the valve opening degree of the switch valves of other water distributors in the wireless stratified water injection process is the same as the valve opening degree during stratified water injection.

[0046] Optionally, when the pressure change value of the oil pipe in the wireless stratified water injection process is less than the predetermined pressure threshold, when controlling the switch valve of the target layer water distributor to operate fully open or fully closed, the switch valve of other layer water distributors in the wireless stratified water injection process can be adjusted to reduce the valve opening.

[0047] In this embodiment, when the pressure change value of the oil pipe in the wireless stratified water injection process is less than the predetermined pressure threshold, that is, when the pressure change value of the oil pipe is small, the valve opening of the switching valve of other layer water distributors in the wireless stratified water injection process can be appropriately reduced to cooperate with the target layer water distributor, so as to better complete the setting of the target layer communication pulse width.

[0048] S230. Determine the communication pulse width corresponding to the pressure change value, and set the target layer according to the communication pulse width to realize target layer pulse width adaptive wireless communication.

[0049] In this solution, different pressure change values ​​correspond to different communication pulse widths, and the relationship between pressure change values ​​and communication pulse widths can be preset.

[0050] In this embodiment, after determining the pressure change value, the communication pulse width corresponding to the pressure change value can be determined according to the pre-set relationship between the pressure change value and the communication pulse width. The target layer is then set according to the optimal communication pulse width, that is, the optimal communication pulse width is set as the key parameter of the target layer. Communication is carried out according to the pressure pulse communication principle to maximize the communication efficiency potential of the target layer.

[0051] Optionally, determining the communication pulse width corresponding to the pressure change value includes:

[0052] The pressure change value is compared with a predetermined pressure range to determine the communication pulse width corresponding to the pressure change value.

[0053] In this scheme, the communication pulse width corresponding to the pressure change value can be determined based on the magnitude of the pressure change value.

[0054] By setting different communication pulse widths, the communication efficiency and reliability of each layer of the wavecode wireless communication are improved, thereby maximizing the overall well wireless communication efficiency.

[0055] Optionally, the pressure range includes a first pressure range, a second pressure range, and a third pressure range;

[0056] Accordingly, the pressure change value is compared with a predetermined pressure range to determine the communication pulse width corresponding to the pressure change value, including:

[0057] If the pressure change value is within the first pressure range, then the communication pulse width corresponding to the pressure change value is determined as the first communication pulse width;

[0058] If the pressure change value is within the second pressure range, then the communication pulse width corresponding to the pressure change value is determined as the second communication pulse width;

[0059] If the pressure change value is within the third pressure range, then the communication pulse width corresponding to the pressure change value is determined as the third communication pulse width;

[0060] Wherein, the first communication pulse width is smaller than the second communication pulse width; the second communication pulse width is smaller than the third communication pulse width.

[0061] In this embodiment, the first pressure range, the second pressure range, and the third pressure range can be set according to the pulse width adaptive wireless communication requirements. Preferably, the first pressure range can be set to greater than 1 MPa; the second pressure range can be set to 0.5-1 MPa; and the third pressure range can be set to 0.2-0.5 MPa. Below 0.2 MPa, normal decoding cannot be achieved, and other layers need to be reduced to cooperate.

[0062] In this scheme, the first, second, and third communication pulse widths can also be set according to the pulse width adaptive wireless communication requirements. Preferably, the first communication pulse width can be set to 3 seconds; the second communication pulse width to 5 seconds; and the third communication pulse width to 10 seconds.

[0063] Specifically, such as Figure 6As shown, when the pressure change value is within the first pressure range, i.e., the pressure change value is greater than 1 MPa, the communication pulse width is set to 3 seconds; when the pressure change value is within the second pressure range, i.e. the pressure change value is greater than or equal to 0.5 MPa and less than or equal to 1 MPa, the communication pulse width is set to 5 seconds; when the pressure change value is within the third pressure range, i.e. the pressure change value is greater than or equal to 0.2 MPa and less than 0.5 MPa, the communication pulse width is set to 10 seconds.

[0064] Furthermore, such as Figure 6 As shown, the target layer is set with the optimal communication pulse width, and communication is performed based on the pressure pulse communication principle.

[0065] By enabling the water distributor to self-test, the pulse width of each communication layer is adaptive, which improves the communication efficiency and reliability of each layer of the wavecode wireless communication, thereby maximizing the efficiency of the whole well wireless communication.

[0066] The technical solution of this invention determines the target layer in the wireless stratified water injection process, controls the on / off valve of the target layer water distributor to operate fully open and fully closed, obtains the pressure change value of the tubing in the wireless stratified water injection process, then determines the communication pulse width corresponding to the pressure change value, and sets the target layer according to the communication pulse width to achieve target layer pulse width adaptive wireless communication. By implementing this technical solution, through the water distributor self-test, the communication pulse width of each layer is adaptively adjusted, improving the communication efficiency and reliability of each layer of wavecode wireless communication, thereby maximizing the overall well wireless communication efficiency.

[0079] Wherein, the first communication pulse width is smaller than the second communication pulse width; the second communication pulse width is smaller than the third communication pulse width.
