Description

Technical Field

[0001] The invention belongs to the technical field of petroleum geological exploration and relates to a highly efficient excitation management system and method for a controllable vibrator. Background Art

[0002] A controllable seismic source is a mechanical seismic source that relies on a vibrator installed on a special vehicle to continuously impact the ground to generate seismic fluctuations. It is also called a continuous vibration seismic source. Because the continuous time of vibration and the frequency variation range can be artificially controlled, it is also called a controllable seismic source.

[0003] When the controllable seismic source control device sends a start command to the controllable seismic source, the controllable seismic source can be started. At present, the controllable seismic source control device usually sends the start command in the following way: the instrument host remotely starts the controllable seismic source control device through a communication method such as a radio station to send the start command, or the controllable seismic source control device sends the start command to the controllable seismic source at a fixed time.

[0004] However, the above method usually has the following technical problems: First, when using a communication method such as a radio station to communicate in an area with obvious environmental interference such as high voltage electricity, it is necessary to change the position of the instrument host to ensure that the instrument host is in an environment where it can communicate normally, which increases the waiting time of the controllable vibrator control device and reduces the excitation efficiency of the controllable vibrator control device; Second, the controllable vibrator control device sends a start command to the controllable vibrators at a fixed time. When there is a problem with the source data of a group of controllable vibrators, the waiting time of other sources will be increased, reducing the excitation efficiency of the controllable vibrator control device.

[0005] like Figure 1 A schematic diagram of an existing controllable seismic source excitation management mode is shown. It can be seen from the figure that the instrument host adopts a polling-specified reply method; the excitation condition is: a reliable data connection needs to be maintained between the instrument host and the corresponding seismic source. The H time period in the figure is the return gap of the PSS report, i.e., the quality control data. The time period is limited. The larger the data, the longer the time. If this time period is missed, the data will be lost and need to be re-vibrated. This excitation management method is inefficient. Summary of the invention

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A highly efficient excitation management system for controllable vibrator includes an inter-group communication device, a data processing device and a mobile device; the inter-group communication device is connected to the data processing device by circuit, and the data processing device is connected to the mobile device by circuit; The data processing device, on the one hand, receives the navigation and positioning data sent by the associated navigation and positioning host, and the source-related data sent by the mobile device, combines the navigation and positioning data and the source-related data into first source data, and sends the first source data to the inter-group communication device; on the other hand, receives the second source data sent by the inter-group communication device, and sends the second source data to the mobile device; the third party sends an excitation control signal to the mobile device; The inter-group communication device receives the first seismic source data sent by the data processing device on the one hand, and sends the first seismic source data to the target vibrator efficient excitation management system, and receives the second seismic source data sent by the target vibrator efficient excitation management system on the other hand, and sends the second seismic source data to the data processing device; The mobile device receives the excitation control signal sent by the data processing device on the one hand, and sends the excitation control signal to the associated controllable source control device, receives the quality control data sent by the associated controllable source control device on the second hand, stores and displays the quality control data, and receives the source-related data sent by the associated controllable source control device on the third hand, and sends the source-related data to the data processing device; The target vibroseis efficient excitation management system refers to a vibroseis efficient excitation management system other than the vibroseis efficient excitation management system to which the inter-group communication device belongs.

[0008] As a limitation, the controllable seismic source efficient excitation management system also includes a power management device, and the power output end of the power management device is respectively connected to the power input end of the inter-group communication device and the data processing device to provide power for the inter-group communication device and the data processing device.

[0009] As a further limitation, the data processing device includes a main control processor and is provided with a serial interface, a first network interface and a second network interface; The output end of the power management device is connected to the power input end of the main control processor, the main control processor is connected to the inter-group communication device through a serial interface, the main control processor is connected to the mobile device through a first network interface, and the main control processor is connected to the associated navigation and positioning host through a second network interface.

[0010] A vibrator efficient excitation management method is implemented by using the above-mentioned vibrator efficient excitation management system. On the one hand, the method shares data with a target vibrator efficient excitation management system in real time through an inter-group communication device; on the other hand, a mobile device responds to received quality control data sent by an associated vibrator control device, stores and displays the quality control data; The process of sharing data includes sending first seismic source data to the target vibroseis efficient excitation management system through the inter-group communication device at a specified time interval, and also includes receiving second seismic source data sent by the target vibroseis efficient excitation management system through the inter-group communication device at a specified time interval and responding; The process of forming the first source data includes: S1, the mobile device receives the seismic source related data sent by the associated controllable vibrator control device, and sends the seismic source related data to the data processing device; S2, the data processing device responds to the received navigation and positioning data sent by the associated navigation and positioning host and the earthquake source related data sent by the mobile device, combines the navigation and positioning data and the earthquake source related data into first earthquake source data, and sends the first earthquake source data to the inter-group communication device; The response to the second source data includes the following process: P1, the inter-group communication device sends the second seismic source data to the data processing device in response to the received second seismic source data sent by the target controllable vibrator efficient excitation management system; P2, the data processing device sends an excitation control signal to the mobile device in response to the first seismic source data and the second seismic source data received from the inter-group communication device; P3. The mobile device sends an excitation control signal to the associated control device of the controllable vibrator in response to the received excitation control signal sent by the data processing device.

[0011] As a limitation, step P2 is performed in the following order: P21, the data processing device compares the first seismic source data and the second seismic source data according to the excitation time distance rule to generate an excitation control signal; P22. The data processing device sends the excitation control signal to the mobile device; The excitation time distance rule is to determine the excitation time intervals between different groups of seismic sources based on the distances between different groups of seismic sources.

[0013] As a third limitation, the second seismic source data includes the positioning information, seismic source group number, and seismic source status of the excitation point corresponding to the target controllable seismic source efficient excitation management system.

[0016] As a sixth limitation, the quality control data includes peak output, average output, peak distortion, and average distortion.

[0017] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art: (1) The reason why the excitation efficiency of the controllable vibrator control device is reduced in the prior art is that: when using the communication method of a radio station to communicate in an area with obvious environmental interference such as high voltage electricity, it is necessary to change the position of the instrument host to ensure that the instrument host is in an environment where normal communication can be achieved, which increases the waiting time of the controllable vibrator control device. The present invention can realize the sharing of vibrator data between groups by setting an inter-group communication device, thereby improving the excitation management efficiency of the controllable vibrator; (2) The present invention can realize the sharing of data information such as geographic location data, source status data, and excitation time between groups. Each source group can realize local autonomous excitation management operations through the shared data information and complete autonomous excitation operation tasks according to the time distance excitation rules. It not only abandons the cumbersome master-slave timing communication excitation management link of the traditional instrument host, but also completely gets rid of the traditional instrument host remote excitation management mode, effectively solves the problem of reduced excitation efficiency caused by communication barriers, and improves the excitation management efficiency of controllable vibrator. (3) In the prior art, a controllable seismic source control device sends a start command to the controllable seismic source at a fixed time. When the seismic source data of a group of controllable seismic sources has a problem, the waiting time of other seismic sources will be increased. The present invention optimizes the controllable seismic source excitation method, compares and processes the first seismic source data and the second seismic source data according to the excitation time distance rule to generate an excitation control signal, and uses the time distance excitation rule to complete the autonomous excitation operation task. Compared with the use of a fixed excitation time slot cycle management method to excite the operation when there is no signal, the excitation management efficiency is improved.

[0018] The invention belongs to the technical field of petroleum geological exploration and can improve the excitation management efficiency of controllable vibrators. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example 1 A highly efficient controllable vibrator excitation management system 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 connected to the data processing device circuit, and the data processing device is connected to the mobile device circuit.

[0023] The data processing device, on the one hand, receives the navigation and positioning data sent by the associated navigation and positioning host, and the source-related data sent by the mobile device, combines the navigation and positioning data and the source-related data into first source data, and sends the first source data to the inter-group communication device; on the other hand, receives the second source data sent by the inter-group communication device, and sends the second source data to the mobile device; and the third party sends an excitation control signal to the mobile device.

[0024] On the one hand, 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 efficient excitation management system. On the other hand, it receives the second seismic source data sent by the target controllable seismic source efficient excitation management system and sends the second seismic source data to the data processing device.

[0025] On the one hand, the mobile device receives the excitation control signal sent by the data processing device and sends the excitation control signal to the associated controllable seismic source control device; on the second hand, it receives the quality control data sent by the associated controllable seismic source control device, stores and displays the quality control data; on the third hand, it 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.

[0026] The target vibrator efficient excitation management system refers to a vibrator efficient excitation management system other than the vibrator efficient excitation management system to which the inter-group communication device belongs.

[0027] Further, if Figure 3 As shown, this embodiment further includes a power management device, 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 respectively, to supply power to the inter-group communication device and the data processing device. In this embodiment, the power management device can provide a DC voltage of 9V to 36V to the above-mentioned inter-group communication device and the above-mentioned data processing device.

[0028] In this embodiment, Figure 4 As shown, the data processing device includes a main control processor, and is provided with a serial interface, a first network interface and a second network interface; the output end of the power management device is connected to the power input end of the main control processor, the main control processor is connected to the inter-group communication device through the serial interface, the main control processor is connected to the mobile device through the first network interface, and the main control processor is connected to the associated navigation and positioning host through the second network interface.

[0029] The inter-group communication device is a device with wireless communication. The inter-group communication device in this embodiment adopts a P900 data transmission device.

[0030] The data processing device is a device that can send an excitation control signal. In this embodiment, the main control processor of the data processing device adopts 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.

[0031] The mobile device is a device that can display quality control data. In this embodiment, the mobile device is a tablet computer or a mobile phone. The associated controllable vibrator control device is a device used to start the current controllable vibrator. In this embodiment, the controllable vibrator controller adopts the VE series, and the VIBPRO HD series can also be used. The controllable vibrator is a source that generates seismic waves of set frequency and intensity under the control of the controllable vibrator controller.

[0032] In this embodiment, the first source data is the source data of the controllable source corresponding to the current controllable source efficient excitation management device, including the navigation positioning data and source-related data corresponding to the current controllable source. The second source data is the source data of the controllable source corresponding to the target controllable source efficient excitation management system, including the navigation positioning data and source-related data corresponding to the target controllable source. The above-mentioned navigation positioning data includes positioning information, and the source-related data includes the source group number and the source status.

[0033] The above-mentioned location information may be the location information of the corresponding controllable seismic source. The above-mentioned seismic source group number may be the group number of the group to which the corresponding controllable seismic source belongs. Specifically, in this embodiment, a group number may uniquely determine the group to which a controllable seismic source belongs. The group to which the controllable seismic source belongs may include a preset number of controllable seismic sources. For example, the preset number may be 3. The above-mentioned seismic source state may be the seismic source state of the corresponding controllable seismic source. For example, the seismic source state may be ready, which may indicate that an excitation control signal may be sent to a controllable seismic source control device corresponding to the corresponding controllable seismic source. The seismic source state may also be preparing, which may indicate that the corresponding controllable seismic source is not ready and cannot send an excitation control signal to the corresponding controllable seismic source control device. The seismic source state may also be vibration ended, which may indicate that an excitation control signal has been sent to the controllable seismic source control device corresponding to the corresponding controllable seismic source. The above-mentioned excitation control signal may be an instruction code for starting the above-mentioned controllable seismic source control device. The above-mentioned quality control data may include various control parameters and various control index results of the controllable seismic source during the vibration process. For example, the above-mentioned quality control data may include but is not limited to at least one of the following: peak output, average output, peak distortion, average distortion, etc. Here, the peak output may be the maximum output of the controllable vibrator during the vibration process. The average output may be the average output of the controllable vibrator during the vibration process. The peak distortion may be the maximum distortion of the controllable vibrator during the vibration process. The average distortion may be the average distortion of the controllable vibrator during the vibration process.

[0034] The target vibroseis efficient excitation management device can be any other vibroseis efficient excitation management device except the current vibroseis efficient excitation management device. The associated navigation and positioning host is a positioning host for collecting navigation and positioning data of the vibroseis corresponding to the current vibroseis efficient excitation management device.

[0035] Usually the controllable vibrator is installed on a special vehicle, which is equipped with a navigation and positioning host. Figure 5 As shown, taking two groups of controllable vibrators as an example, each group includes four controllable vibrators, one of which is installed on the main vehicle, and the other three controllable vibrators are installed on the auxiliary vehicle. The four controllable vibrators in the same group are excited by the same controllable vibrator control device sending an excitation control signal to complete the autonomous excitation within the group. One controllable vibrator control device corresponds to one controllable vibrator efficient excitation management system provided by this embodiment.

[0036] by Figure 5For example, the high-efficiency excitation management system of the controllable source corresponding to the first group of controllable sources is regarded as the current high-efficiency excitation management system of the controllable source, and the high-efficiency excitation management system of the controllable source corresponding to the second group of controllable sources is the target high-efficiency excitation management system of the controllable source. If more groups of controllable sources are added, the corresponding newly added high-efficiency excitation management systems are all target high-efficiency excitation management systems of the controllable source. In other words, any high-efficiency excitation management system of the controllable source is regarded as the current high-efficiency excitation management system of the controllable source, and the other high-efficiency excitation management systems of the controllable source are all target high-efficiency excitation management systems of the controllable source. In this embodiment, each group of high-efficiency excitation management systems of the controllable source is installed on the main vehicle, and different groups share the source group number, source position, and source status through broadcast sharing by the inter-group communication device installed on the main vehicle.

[0037] Example 2 A method for efficient excitation management of a controllable vibrator This embodiment is implemented by using Embodiment 1. During the process of efficient excitation management of controllable seismic sources, on the one hand, the efficient excitation management system of the controllable seismic source shares data with the target efficient excitation management system of the controllable seismic source in real time through the inter-group communication device; on the other hand, the mobile device responds to the quality control data received from the associated controllable seismic source control device, stores and displays the quality control data.

[0038] The process of sharing data includes sending the first seismic source data to the target controllable seismic source efficient excitation management system through the inter-group communication device at the specified time interval, and also includes receiving the second seismic source data sent by the target controllable seismic source efficient excitation management system through the inter-group communication device at the specified time interval and responding.

[0039] The process of forming the first source data includes: S1, the mobile device receives the seismic source related data sent by the associated controllable vibrator control device, and sends the seismic source related data to the data processing device; S2, the data processing device responds to the received navigation and positioning data sent by the associated navigation and positioning host and the earthquake source related data sent by the mobile device, combines the navigation and positioning data and the earthquake source related data into first earthquake source data, and sends the first earthquake source data to the inter-group communication device; The response to the second source data includes the following process: P1, the inter-group communication device sends the second seismic source data to the data processing device in response to the received second seismic source data sent by the target controllable vibrator efficient excitation management system; P2, the data processing device sends an excitation control signal to the mobile device in response to the first seismic source data and the second seismic source data received from the inter-group communication device; P3. The mobile device sends an excitation control signal to the associated control device of the controllable vibrator in response to the received excitation control signal sent by the data processing device.

[0040] Wherein, step P2 is performed in the following order: P21, the data processing device compares the first seismic source data and the second seismic source data according to the excitation time distance rule to generate an excitation control signal; P22. The data processing device sends the excitation control signal to the mobile device.

[0041] The excitation time distance rule is to determine the excitation time interval between different groups of seismic sources based on the distances between them.

[0042] Figure 6 This is a functional implementation diagram of the time-distance excitation rule of an embodiment of the present invention. As can be seen from the figure, with the introduction of the concept of time and space domain, the sliding time is no longer fixed during the controllable source excitation operation, and the sliding time changes with the distance. The TD graphic rule is generated in real time, and the time-distance relationship between the source groups will be displayed in the figure to facilitate the judgment of the time-distance relationship and improve the efficiency of autonomous excitation. TD represents time distance.
