Description
TECHNICAL FIELD
[0001] The present application belongs to the technical field of oil geological exploration, and relates to a controllable source high-efficiency excitation management system and method. BACKGROUND
[0002] The controllable source is a mechanical source, which is a vibrator installed on a special vehicle to continuously impact the ground to generate seismic wave motion, also known as a continuous vibration source. Because the continuous time and frequency range of vibration can be artificially controlled, it is also called a controllable source.
[0003] When the controllable source control device sends a start command to the controllable source, the controllable source can be started. At present, the controllable source control device usually adopts the following ways to send a start command: the instrument host remotely starts the controllable source control device to send a start command through a communication mode such as a radio station, or the controllable source control device sends a start command to the controllable source according to a fixed time.
[0004] However, the above-mentioned ways usually have the following technical problems:
[0005] Firstly, when the communication is carried out in an area where the environmental interference such as high voltage is obvious, the position of the instrument host needs to be changed to ensure that the instrument host is in an environment where it can normally communicate, which increases the waiting time of the controllable source control device and reduces the excitation efficiency of the controllable source control device.
[0006] Secondly, when there is a problem with the source data of a group of controllable sources, the waiting time of other sources will be increased, and the excitation efficiency of the controllable source control device will be reduced.
[0007] For example Figure 1 An existing controllable source excitation management mode is shown in the figure, from which it can be seen that the instrument host adopts a polling-designated reply mode; the excitation condition is that a reliable data connection needs to be implemented between the instrument host and the corresponding source, and the H time period in the figure is a PSS report, i.e., the backhaul gap of quality control data. The time period is limited, and the larger the data is, the longer the time is. If the data is missed, the data will be lost, and the source needs to be re-excited. This excitation management mode is low in efficiency. SUMMARY
[0008] The purpose of the present application is to provide a controllable source high-efficiency excitation management system to improve the excitation management efficiency of the controllable source.
[0009] Another purpose of the present application is to provide a controllable source high-efficiency excitation management method to optimize the excitation method of the controllable source and improve the excitation management efficiency of the controllable source.
[0010] The application adopts the technical solutions as follows to achieve the above-mentioned purpose.

[0015] The target controllable source high-efficiency excitation management system refers to a controllable source high-efficiency excitation management system other than the controllable source high-efficiency excitation management system to which the inter-group communication device belongs.
[0016] As a limitation, the controllable source high-efficiency excitation management system further comprises a power management device, and the power output end of the power management device is connected to the power input end of the inter-group communication device and the data processing device to supply power to the inter-group communication device and the data processing device.
[0017] As a further limitation, the data processing device comprises a master processor, and is provided with a serial interface, a first network interface and a second network interface.
[0018] The output end of the power management device is connected to the power input end of the master processor, the master processor is connected to the inter-group communication device through the serial interface, the master processor is connected to the mobile device through the first network interface, and the master processor is connected to the associated navigation positioning host through the second network interface.
[0019] The application discloses a controllable source high-efficiency excitation management method, which is realized by using the controllable source high-efficiency excitation management system, and shares data with the target controllable source high-efficiency excitation management system in real time through the inter-group communication device; the mobile device stores and displays the quality control data sent by the associated controllable source control device in response to the received quality control data.
[0020] The process of sharing data comprises the following steps: sending first source data to the target controllable source high-efficiency excitation management system at a specified time interval through the inter-group communication device, and receiving second source data sent by the target controllable source high-efficiency excitation management system at a specified time interval through the inter-group communication device and responding to the second source data.
[0021] The process of forming the first source data comprises the following steps:
[0022] S1, the mobile device receives source-related data sent by the associated controllable source control device, and sends the source-related data to the data processing device;
[0023] S2, the data processing device forms first source data by combining the navigation positioning data sent by the associated navigation positioning host and the source-related data sent by the mobile device in response to the received navigation positioning data, and sends the first source data to the inter-group communication device.
[0024] The response to the second source data comprises the following process:
[0025] P1, the inter-group communication device sends the second source data to the data processing device in response to the received second source data sent by the target controllable source high-efficiency excitation management system;
[0026] P2, the data processing device sends an excitation control signal to the mobile device in response to the first source data and the received second source data sent by the inter-group communication device;
[0027] P3, the mobile device sends an excitation control signal to the associated controllable source control device in response to the received excitation control signal sent by the data processing device.
[0028] As a limitation, step P2 is performed in the following order:
[0029] P21, the data processing device compares and processes the first source data and the second source data according to an excitation time distance rule to generate an excitation control signal;
[0030] P22, the data processing device sends the excitation control signal to the mobile device;

[0038] Compared with the prior art, the technical progress achieved by the present application is that:
[0039] (1) In the prior art, the reason for reducing the firing efficiency of the vibroseis control device is that when using the radio station communication mode to communicate in an area with obvious environmental interference such as high voltage, the position of the instrument host needs to be changed to ensure that the instrument host is in an environment where it can normally communicate, which increases the waiting time of the vibroseis control device. The present application can realize group-to-group seismic data sharing by setting a group-to-group communication device, thereby improving the vibroseis firing management efficiency.
[0040] (2) The present application can realize group-to-group geographic position data, seismic source state data, and firing time data information sharing. Each seismic source group realizes local autonomous firing management operation through shared data information, and completes the autonomous firing operation task according to the time distance firing rule. Not only does it abandon the traditional instrument host cumbersome master-slave time sequence communication firing management link, but it also completely gets rid of the traditional instrument host remote firing management mode, effectively solves the problem of firing efficiency reduction caused by communication obstacles, and improves the vibroseis firing management efficiency.
[0041] (3) In the prior art, the controllable source control equipment sends start commands to the controllable source at fixed times. When there is a problem with the source data of a group of controllable sources, the waiting time of other sources will be increased. The present invention optimizes the controllable source excitation method. The first source data and the second source data are compared and processed according to the excitation time distance rule to generate an excitation control signal. The time distance excitation rule is used to complete the autonomous excitation operation task. Compared with the excitation operation using the fixed excitation time slot cyclic management method when there is no signal, the excitation management efficiency is improved.
[0042] This invention belongs to the field of petroleum geological exploration technology and can improve the efficiency of excitation management of controllable seismic sources. Attached Figure Description

[0051] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.
[0052] Example 1: A Controllable Vibration Source High-Efficiency Excitation Management System
[0053] like Figure 2 As shown, this embodiment includes an inter-group communication device, a data processing device, and a mobile device. The inter-group communication device is circuitically connected to the data processing device, and the data processing device is circuitically connected to the mobile device.
[0054] The data processing device receives the navigation positioning data sent by the associated navigation positioning host and the seismic source related data sent by the mobile device, and forms first seismic source data by combining the navigation positioning data and the seismic source related data, and sends the first seismic source data to the inter-group communication device; receives the second seismic source data sent by the inter-group communication device, and sends the second seismic source data to the mobile device; and sends the firing control signal to the mobile device.
[0055] The inter-group communication device receives the first seismic source data sent by the data processing device, and sends the first seismic source data to the target controllable seismic source high-efficiency firing management system, and receives the second seismic source data sent by the target controllable seismic source high-efficiency firing management system, and sends the second seismic source data to the data processing device.
[0056] The mobile device receives the firing control signal sent by the data processing device, and sends the firing control signal to the associated controllable seismic source control device, receives the quality control data sent by the associated controllable seismic source control device, stores and displays the quality control data, and receives the seismic source related data sent by the associated controllable seismic source control device, and sends the seismic source related data to the data processing device.
[0057] The target controllable seismic source high-efficiency firing management system refers to a controllable seismic source high-efficiency firing management system other than the controllable seismic source high-efficiency firing management system to which the inter-group communication device belongs.
[0058] Further, as shown in Figure 3 The power management device is connected to the power input terminals of the inter-group communication device and the data processing device, and supplies power to the inter-group communication device and the data processing device. In this embodiment, the power management device can provide a direct current voltage of 9V to 36V to the inter-group communication device and the data processing device.
[0059] In this embodiment, as shown in Figure 4 The data processing device includes a master control processor, and is provided with a serial interface, a first network interface and a second network interface; the output terminal of the power management device is connected to the power input terminal of the master control processor, the master control processor is connected to the inter-group communication device through the serial interface, the master control processor is connected to the mobile device through the first network interface, and the master control processor is connected to the associated navigation positioning host through the second network interface.
[0060] The inter-group communication device is a device with wireless communication. In this embodiment, the inter-group communication device adopts a P900 data transmission device.
[0061] The data processing device is a device capable of sending the excitation control signal. In the embodiment, the host processor of the data processing device is a SAMA5D3 processor, and the data processing device is provided with at least three interfaces. The three interfaces include an Ethernet interface, a 3x high-speed USB (USB3.0) interface, and a UART (Universal Asynchronous Receiver / Transmitter) interface.
[0062] The mobile device is a device capable of displaying the quality control data. In the embodiment, the mobile device is a tablet computer or a mobile phone. The associated controllable source control device is a device for starting the current controllable source. In the embodiment, the controllable source controller is a VE series, and can also be a VIBPRO HD series. The controllable source is a source for generating seismic waves of a set frequency and intensity under the control of the controllable source controller.
[0063] In the embodiment, the first source data is the source data of the controllable source corresponding to the current controllable source high-efficiency excitation management device, including navigation positioning data corresponding to the current controllable source and source-related data. The second source data is the source data of the controllable source corresponding to the target controllable source high-efficiency excitation management system, including navigation positioning data corresponding to the target controllable source and source-related data. The navigation positioning data includes positioning information, and the source-related data includes a source group number and a source state.
[0064] The position information can be position information of the corresponding controllable vibrator. The group number of the vibrator can be a group number of a group in which the corresponding controllable vibrator is located. Specifically, one group number in the embodiment can uniquely determine a group in which one controllable vibrator is located. The group in which the controllable vibrator is located can include a preset number of controllable vibrators. For example, the preset number can be 3. The vibrator state can be a vibrator state of the corresponding controllable vibrator. For example, the vibrator state can be ready, which can indicate that an excitation control signal can be sent to a controllable vibrator control device corresponding to the corresponding controllable vibrator. The vibrator state can also be in preparation, which can indicate that the corresponding controllable vibrator is not ready and cannot send an excitation control signal to the controllable vibrator control device corresponding to the corresponding controllable vibrator. The vibrator state can also be vibration end, which can indicate that an excitation control signal has been sent to the controllable vibrator control device corresponding to the corresponding controllable vibrator. The excitation control signal can be an instruction code for starting the controllable vibrator control device. The quality control data can include various control parameters and various control index results of the controllable vibrator during vibration. For example, the quality control data can include at least one of the following: peak output, average output, peak distortion, average distortion, etc. Here, the peak output can be the maximum output of the controllable vibrator during vibration. The average output can be the average output of the controllable vibrator during vibration. The peak distortion can be the maximum distortion of the controllable vibrator during vibration. The average distortion can be the average distortion of the controllable vibrator during vibration.
[0065] The target controllable vibrator efficient excitation management device can be any controllable vibrator efficient excitation management device other than the current controllable vibrator efficient excitation management device. The associated navigation positioning host is a positioning host for collecting navigation positioning data of the controllable vibrator corresponding to the current controllable vibrator efficient excitation management device.
[0066] Generally, controllable vibrators are installed on special vehicles, and the special vehicles are configured with navigation positioning hosts. As shown in Figure 5 , two groups of controllable vibrators are taken as an example, each group including four controllable vibrators, one of which is installed on a main vehicle and the other three of which are installed on a secondary vehicle. The four controllable vibrators in the same group are excited by sending an excitation control signal by one controllable vibrator control device to complete autonomous excitation within the group. One controllable vibrator control device corresponds to one controllable vibrator efficient excitation management system provided in the embodiment.
[0067] As shown in Figure 5For example, the controllable source high-efficiency excitation management system corresponding to the first group of controllable sources is taken as the current controllable source high-efficiency excitation management system, and the controllable source high-efficiency excitation management system corresponding to the second group of controllable sources is the target controllable source high-efficiency excitation management system. If more groups of controllable sources are added, the controllable source high-efficiency excitation management systems corresponding to the newly added controllable sources are all target controllable source high-efficiency excitation management systems. That is, any controllable source high-efficiency excitation management system is taken as the current controllable source high-efficiency excitation management system, and other controllable source high-efficiency excitation management systems are all target controllable source high-efficiency excitation management systems. In this embodiment, the controllable source high-efficiency excitation management system of each group is mounted on the main vehicle, and the source group number, source position, and source state are shared through the inter-group communication device mounted on the main vehicle.

[0070] The process of sharing data includes sending first source data to the target controllable source high-efficiency excitation management system at a specified time interval through the inter-group communication device, and receiving second source data sent by the target controllable source high-efficiency excitation management system at a specified time interval through the inter-group communication device and responding.

[0072] S1, the mobile device receives the source-related data sent by the associated controllable source control device, and sends the source-related data to the data processing device;
[0073] S2, the data processing device responds to the navigation positioning data sent by the associated navigation positioning host and the source-related data sent by the mobile device to form the first source data, and sends the first source data to the inter-group communication device;
[0074] The response to the second source data includes the following process:

[0080] P22, the data processing device sends the excitation control signal to the mobile device.
[0081] The excitation time-distance rule is to judge the excitation time interval between different groups of seismic sources according to the distance between different groups of seismic sources.
[0082] Figure 6 It is the function implementation diagram of the time-distance excitation rule of the embodiment of the present application. As can be seen from the diagram, the concept of time-space domain is introduced, the sliding time is no longer fixed during the controllable seismic source excitation operation, and the sliding time changes with the distance. The TD pattern rule is generated in real time, and the time-distance relationship between the seismic source groups is displayed in the diagram to judge the time-distance relationship and improve the autonomous excitation efficiency. TD represents time distance.
