[0002] In oil seismic exploration operations, artificial stimulation is required to generate seismic waves, and the acquisition equipment receives the seismic waves for later processing and analysis. At present, node acquisition equipment has begun to be used in most exploration areas and has become the development trend of oil seismic exploration acquisition equipment. Compared with conventional wired acquisition equipment, node acquisition equipment (hereinafter referred to as node) has significant advantages such as small size and easy deployment. It is particularly suitable for deployment in terrain conditions such as mountainous areas and farmland water networks, which significantly reduces the manpower and machinery costs of deployment.

[0003] Currently, when nodes are used to collect seismic data after well gun excitation, subjective judgment is made and the well gun excitation status is recorded at the excitation site. After the node is recovered, the synthetic seismic data is downloaded to determine whether the well gun excitation meets the requirements. Summary of the invention

[0004] Currently, when using nodes to collect seismic data from well-blasting, people can only make subjective judgments and record the well-blasting excitation status at the excitation site, which cannot fully and accurately reflect the well-blasting excitation effect.

[0058] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0059] In the prior art, when using nodes to collect seismic data stimulated by well blasting, the well blasting excitation state can only be subjectively judged by the personnel on the blasting site. After the data collection is completed, the collected data is obtained from the nodes for synthesis, and the synthetic seismic data is judged. If the synthetic seismic data does not meet the requirements, it is difficult to take remedial measures when the collection equipment has been recovered, resulting in poor quality of seismic data collected after well blasting. If considering using a dedicated large-scale data acquisition device to receive seismic data stimulated by well blasting to monitor the well blasting excitation effect, it will increase the weight of the equipment carried by field construction personnel and the complexity of operation.

[0060] In order to solve the problems existing in the prior art, the embodiments of the present invention provide a method, device and system for monitoring node seismic data of well blasting. According to the method design scheme and the construction process, the well blasting construction shot point file is imported into the mobile terminal, and the shot point position in the shot point file is consistent with the actual shot point position in the field. Before the well blasting is excited, the mobile terminal is used to send a seismic data return instruction to the seismic data acquisition node near the well blasting point. After receiving the instruction, the seismic data acquisition node establishes a communication connection with the mobile terminal and can send the real-time collected seismic data to the mobile terminal; after the well blasting is excited, the seismic data acquisition node sends the real-time collected seismic data to the mobile terminal. After the well blasting is completed, data analysis is started, and the monitoring indicators such as the peak value, root mean square value, main frequency, bandwidth and other monitoring indicators of the seismic data obtained by analysis are displayed and stored in the mobile terminal.

[0061] Embodiment 1

[0062] Embodiment 1 of the present invention provides a method for monitoring node seismic data of well gun excitation, the process of which is as follows: Figure 1As shown, the following steps are included:

[0063] Step S101: The mobile terminal sends a seismic data return instruction to the seismic data acquisition node.

[0064] The mobile terminal can send seismic data return instructions to the seismic data acquisition node by wireless communication methods such as unicast or broadcast.

[0065] Step S102: The mobile terminal receives real-time seismic data sent by the seismic data acquisition node in response to the seismic data feedback instruction.

[0066] After receiving the seismic data return instruction, the seismic data acquisition node starts wireless communication; collects real-time seismic data after the well gun is fired and sends it to the mobile terminal; the mobile terminal receives the real-time seismic data sent by the seismic data acquisition node in response to the seismic data return instruction. The return instruction and real-time seismic data can be transmitted using a specific data transmission protocol.

[0067] Step S103: After the mobile terminal determines that the real-time seismic data of the preset receiving time has been received, it analyzes the received real-time seismic data, determines whether the firing state of the well gun and the preset seismic data monitoring indicators meet the expected requirements, and displays the monitoring results to the user through a preset prompt signal. The prompt signal includes at least one of a prompt signal that meets the expected requirements, a prompt signal that does not meet the expected requirements, and a prompt signal for the firing state of the well gun.

[0068] After receiving the real-time seismic data sent by the seismic data acquisition node, the mobile terminal determines whether the duration of the received seismic data reaches the preset receiving duration. If so, it stops receiving the real-time seismic data and analyzes the received real-time seismic data.

[0069] The analysis process includes: judging whether the monitoring indicators in the received real-time seismic data meet the corresponding detection indicator threshold requirements. If all monitoring indicators meet the detection indicator threshold requirements, it is determined that the seismic data monitoring indicators meet the expected requirements; otherwise, it is considered that they do not meet the expected requirements; and the mobile terminal detects whether the excitation state of the well gun is completed or not. The well gun monitoring results are obtained based on the judgment results of the monitoring indicators and the judgment results of the well gun excitation state, and the monitoring results are displayed to the user in the form of prompt signals.

[0070] Prompt signals for meeting expected requirements, prompt signals for not meeting expected requirements, and prompt signals for well gun excitation status may use indicator lights of different colors.

[0071] The above method of the embodiment of the present invention can monitor node seismic data of well gun excitation for well gun shooting points with different line numbers and stake numbers in different gun groups, and obtain monitoring results of different gun groups.

[0072] In the above method of the embodiment of the present invention, the mobile terminal instructs the seismic data acquisition node to return the collected real-time seismic data through the seismic data return instruction, performs real-time analysis on the real-time seismic data returned by the seismic data acquisition node, determines whether the excitation state of the well gun and the preset seismic data monitoring indicators meet the expected requirements, and displays the monitoring results to the user through a preset prompt signal, thereby achieving the possibility of obtaining whether the excitation state of the well gun is normal, whether the seismic data collected by the acquisition node meets expectations, etc. without the need for on-site subjective judgment and confirmation, thereby achieving automatic completion of the monitoring and judgment of the well gun excitation state and seismic data without the use of dedicated data acquisition equipment, comprehensively and accurately reflecting the well gun excitation effect and promptly dealing with the situation where the excitation effect is not ideal, thereby obtaining high-quality seismic data.

[0073] Embodiment 2

[0074] Embodiment 2 of the present invention provides a method for monitoring node seismic data of well gun excitation, the process of which is as follows: Figure 2 As shown, the following steps are included:

[0075] Step S201: The mobile terminal sends a query instruction to the seismic data acquisition node in a broadcasting manner.

[0076] Step S202: The mobile terminal receives node information data returned by the seismic data acquisition node in response to the query instruction; the node information data includes at least one of the node ID, current acquisition working status, Bluetooth signal strength, and longitude and latitude positions.

[0077] Before the mobile terminal sends the seismic data return instruction to the seismic data acquisition node, it can choose to first execute steps S201 and S202.

[0078] Step S203: The mobile terminal determines the current collection working status of the node according to the node information data.

[0079] Step S204: Selecting a seismic data acquisition node to recover seismic data according to the current acquisition working state of the node, the communication signal strength of the node, the node location, and the preset number of nodes that simultaneously receive seismic data.

[0080] After the mobile terminal receives the node information data returned by the seismic data acquisition node in response to the query instruction, it can also choose to execute steps S203 and 204.

[0081] Step S205: The mobile terminal sends a seismic data return instruction to the seismic data acquisition node.

[0082] In the case of executing step S203 and step S204, the mobile terminal sends the seismic data return instruction to the seismic data acquisition node, including: the mobile terminal sends the seismic data return instruction to the selected seismic data acquisition node.

[0083] Step S206: The mobile terminal receives the real-time seismic data sent by the seismic data acquisition node in response to the seismic data feedback instruction.

[0084] Step S207: After the mobile terminal determines that the real-time seismic data of the preset receiving time has been received, it analyzes the received real-time seismic data to determine whether the excitation state of the well gun and the preset seismic data monitoring indicators meet the expected requirements, and displays the monitoring results to the user through a preset prompt signal, wherein the prompt signal includes at least one of a prompt signal that meets the expected requirements, a prompt signal that does not meet the expected requirements, and a prompt signal for the well gun excitation state.

[0085] Embodiment 3

[0086] Embodiment 2 of the present invention provides a node seismic data monitoring method for well blasting. The method follows the well blasting construction process. Before the well blasting operation, a mobile terminal is used to send a broadcast query command. The seismic data acquisition node within the wireless communication range sends node information data such as ID, acquisition working status, wireless communication signal strength, and longitude and latitude position to the mobile terminal. The mobile terminal selects the seismic data acquisition node to receive and then sends a seismic data return command to the corresponding seismic data acquisition node. After receiving the seismic data return command, the seismic data acquisition node sends the real-time collected seismic data to the mobile terminal. After the well blasting is completed, the mobile terminal analyzes the seismic data returned by multiple seismic data acquisition nodes, including monitoring indicators such as amplitude peak value, root mean square value, main frequency, and bandwidth, and determines whether the well blasting excitation state and the preset seismic data monitoring indicators meet the expected requirements. The monitoring results are displayed and stored on the mobile terminal. The monitoring results can be exported for analysis and timely disposal measures can be taken for the corresponding blasting points.

[0087] In the embodiment of the present invention, a project with 10 survey lines and 1000 detection points is used as an example for explanation. The survey line numbers are 1, 2, 3, ..., 8, 9, 10 respectively; the detection point pile numbers are 1001, 1002, 1003, ..., 1098, 1099, 1100 respectively; 100 detection point nodes are arranged for each survey line; a seismic data acquisition node is arranged at each detection point position, and the seismic data acquisition node can return the ID of the seismic acquisition node, the acquisition working status, the wireless communication signal strength, the longitude and latitude position according to the instruction After establishing a communication connection based on the seismic data return instruction, the seismic data acquisition node can return the seismic data to the mobile terminal in real time while collecting seismic data; for the convenience of explanation, the ID of the seismic data acquisition node and the shot point line number and pile number are respectively corresponded from small to large, such as the IDs of the detection point position nodes of line 1 1001, 1002, 1003, ..., 1098, 1099, 1100 are 11001, 11002, 11003, ..., 11098, 11099, 11100. The well gun excitation is equipped with 4 gun groups, each of which is equipped with 1 mobile terminal. The mobile terminal has a satellite positioning function and can set the number of nodes that receive seismic data acquisition nodes at the same time and the length of time to receive seismic data. Each mobile terminal imports the well gun point file constructed on the day. In the conventional seismic exploration well gun excitation operation process, each group of well gun excitation gun teams has only one group of gun teams in the excitation or about to be excited state at the same time point.

[0088] Arrange the current work arrangement according to the seismic node layout, complete the seismic data acquisition node layout of the detection lines preset in the task, for example, the current task is the seismic data acquisition node layout of three detection lines, where the serial numbers of the three detection lines are set to 2, 3, and 4; set the preset seismic data acquisition nodes on each detection line, for example, 100 seismic data acquisition nodes, the seismic data acquisition node IDs on 2 detection lines are 21001, 21002, 21003, ..., 21098, 21099, 21100, and the seismic data acquisition node IDs of other detection lines are deduced by analogy; the distance between adjacent detection lines is a preset distance, for example, set to 60 meters, and the adjacent distance of seismic data acquisition nodes on the same detection line is a preset distance, for example, 40 meters; after the seismic data acquisition node layout is completed, activate and enter the working state.

[0089] A method for monitoring node seismic data of well-blasting excitation is specifically implemented as follows: Figure 3 As shown, the signaling interaction between the mobile terminal and the seismic data acquisition node is shown in Figure 4 As shown, the method comprises the following steps:

[0090] Step S301: The mobile terminal is started and reaches a preset distance range of a well blast point based on the navigation function of the mobile terminal.

[0091] The operator starts the mobile terminal device and uses the mobile terminal device to navigate to the preset distance range of the well blast point. You can first reach the preset distance range of the well blast point based on the navigation function of the mobile terminal; use the mobile terminal to locate the current location and confirm whether the current location is correct; the specific implementation process starts the mobile terminal, turns on the navigation function of the mobile terminal, and navigates to the specified location according to the work task; the current location is within the safe distance range from the working blast point.

[0092] Step S302: The mobile terminal pre-sets the thresholds of the receiving parameters and the well blasting monitoring indicators.

[0093] The operator sets the receiving parameters and thresholds of the well-gun excitation monitoring indicators on the mobile terminal device through the human-computer interaction interface. The receiving parameters include the number of nodes that simultaneously receive seismic data and the length of time for receiving seismic data; the monitoring indicators include at least one of the seismic data peak value, root mean square value, main frequency, bandwidth, and signal-to-noise ratio.

[0094] For example Figure 5 The current shot point number to be excited is shown as 3 lines 1050.5, and the number of nodes for simultaneously receiving seismic data acquisition and the length of time for receiving seismic data are set on the mobile terminal. Specifically, the number of nodes for simultaneously receiving seismic data is set to 6, and the length of time for receiving seismic data is set to 20 seconds; in this embodiment, the threshold of the well gun excitation monitoring data is set: in this embodiment, the peak value is specifically set to >500mV, the root mean square value is >100mV, the main frequency is 15-40Hz, and the bandwidth is 20-50Hz.

[0095] Before the mobile terminal sends the query instruction in a broadcasting manner, step S201 and step S202 may be optionally performed, or either one of them may be performed.

[0096] Step S303: The mobile terminal sends a query instruction to the seismic data acquisition node in a broadcasting manner.

[0097] like Figure 4 As shown, the operator uses a mobile terminal to send a query instruction to the seismic data acquisition node through wireless communication by broadcasting. For example, the mobile terminal sends the query instruction by broadcasting through wireless communication, and the mobile terminal uses the same wireless communication method as the seismic data acquisition node, and the specific wireless communication method is Bluetooth or WI_FI.

[0098] Step S304: The mobile terminal receives the node information data returned by the seismic data acquisition node in response to the query instruction.

[0099] like Figure 4As shown, after the mobile terminal sends the query command to the seismic data acquisition node, the mobile terminal receives the node information data returned by the seismic data acquisition node in response to the query command; wherein the node information data includes at least one of the node ID, the current acquisition working state, the Bluetooth signal strength, and the longitude and latitude position. For example, the seismic data acquisition node receives the query command sent in the form of broadcast, and the seismic data acquisition node sends the node ID, the current acquisition working state, the wireless communication signal strength, the longitude and latitude position and other data to the mobile terminal.

[0100] Step S305: The mobile terminal determines the current acquisition working status of the node based on the node information data, and selects the seismic data acquisition node to recover the seismic data based on the current acquisition working status of the node, the communication signal strength of the node, the node location and the preset number of nodes that simultaneously receive seismic data.

[0101] After the mobile terminal receives the node information data sent by the seismic data acquisition node, the current working status of the node can be determined based on the node information data. Preferably, the node information data, the current acquisition working status of the node, the communication signal strength of the node, and the node position are displayed visually to the user. The user selects the acquisition node that needs to collect seismic data based on the node information data, the current acquisition working status of the node, the communication signal strength of the node, and the node position. The selected node can also be displayed through a visual interface. Optionally, the relevant node information data can also be stored.

[0102] For example, the seismic data acquisition node near the well blasting point is activated and enters the seismic data acquisition mode. The seismic data acquisition node can transmit the seismic data back to the mobile terminal in real time while collecting seismic data; Figure 5 As shown, the mobile terminal receives information sent back by eight nodes (ID) 31050, 31051, 31049, 31052, 21050, 21051, 41050, and 41051. The mobile terminal removes node 21051 with a large noise value and node (ID) 41050 with a poor Bluetooth signal strength based on the working status of the eight nodes, Bluetooth signal strength, longitude and latitude positions, and information data of six seismic data acquisition nodes set in the mobile terminal, where the acquisition status at least includes acquisition status, detector status, GPS status, noise, etc., and selects the seismic data acquisition nodes (ID) 31050, 31051, 31049, 31052, 21050, and 41051 to be recycled, and displays the selected seismic data acquisition nodes and corresponding related data on the human-computer interaction interface.

[0103] Step S306: The mobile terminal sends a seismic data return instruction to the seismic data acquisition node.

[0104] like Figure 4 As shown, the mobile terminal sends a seismic data return instruction to the seismic data acquisition node. The specific implementation process is that the mobile terminal sends a seismic data return instruction to the selected seismic data acquisition node.

[0105] Step S307: After receiving the seismic data feedback instruction, the seismic data acquisition node collects real-time seismic data after well gun excitation and sends it to the mobile terminal via wireless communication; the mobile terminal receives the real-time seismic data sent by the seismic data acquisition node in response to the seismic data feedback instruction.

[0106] like Figure 4 As shown, after the selected seismic data acquisition node receives the seismic data feedback instruction, it collects real-time seismic data after the well gun is excited through the seismic data sensing device, and sends the collected real-time seismic data through wireless communication; the mobile terminal receives the real-time seismic data sent by the selected seismic data acquisition node in response to the seismic data feedback instruction.

[0107] For example, the well blasting construction personnel complete the blasting of the well blasting points according to the standard process; the seismic data acquisition node sends the real-time collected seismic data to the mobile terminal after receiving the seismic data return instruction; after the mobile terminal receives the seismic data of the specified time length. For example, after the six seismic data acquisition nodes receive the seismic data return instruction, they begin to return the real-time collected seismic data to the mobile terminal through Bluetooth wireless communication; the well blasting construction personnel complete the blasting of the well blasting according to the standard process, and the mobile terminal receives the seismic data for the preset receiving time, the specific preset receiving time is 20 seconds, and the mobile terminal receives 20 seconds of seismic data.

[0108] Step S308: The mobile terminal receives the real-time seismic data sent by the seismic data acquisition node, and determines whether the duration of the received seismic data reaches a preset receiving duration. If so, stop receiving the real-time seismic data and analyze the received real-time seismic data.

[0109] like Figure 4 As shown, after the mobile terminal determines that the real-time seismic data with a preset receiving time has been received, the received real-time seismic data is analyzed. The mobile terminal receives seismic data with a duration of 20 seconds, and determines whether the received 20 seconds meets the preset receiving time. Assuming that the preset receiving time is another preset time of 30 seconds, 20 seconds does not meet the preset receiving time, and the seismic data continues to be received until it meets the preset receiving time. In this embodiment, the preset receiving time is 20 seconds, which meets the preset receiving time. The mobile terminal sends a stop returning seismic data instruction to the seismic data acquisition node, and analyzes the received real-time seismic data.

[0110] Step S309: The mobile terminal determines whether the monitoring indicators in the received real-time seismic data meet the corresponding detection indicator threshold requirements. If all monitoring indicators meet the detection indicator threshold requirements, it is determined that the seismic data monitoring indicators meet the expected requirements; otherwise, it is considered that they do not meet the expected requirements; and the mobile terminal detects the excitation state of the well gun as completed excitation or uncompleted excitation.

[0111] Analyze the received real-time seismic data. During the analysis process, the mobile terminal determines whether the monitoring indicators in the received real-time seismic data meet the corresponding detection indicator threshold requirements. If all monitoring indicators meet the detection indicator threshold requirements, it is determined that the seismic data monitoring indicators meet the expected requirements; otherwise, it is considered that they do not meet the expected requirements; and the mobile terminal detects the excitation state of the well gun as completed excitation or uncompleted excitation. The visual gun point interface in the mobile terminal uses different colors to indicate whether the gun point excitation monitoring results meet expectations. The excitation monitoring results are stored in the mobile terminal and can be exported for analysis.

[0112] For example, if the well gun fails to complete the excitation within the preset receiving time, specifically, within the preset receiving time of 20 seconds, the mobile terminal may repeatedly send seismic data transmission instructions to the seismic data acquisition node; after the mobile terminal automatically analyzes the returned seismic data, the monitoring results such as the peak value, root mean square value, main frequency, and bandwidth of the seismic data are displayed and stored in the mobile terminal. For example, the monitoring results show that the peak value of the seismic data excited by the shot point is 1120mV, the root mean square value is 270mV, the main frequency is 26Hz, and the bandwidth is 37Hz, all of which meet the set threshold requirements. The data monitoring results are displayed in green, the shot points whose data monitoring results do not meet the expectations are displayed in blue, and the shot points that have not completed the excitation are displayed in red.

[0113] In some optional embodiments, the method further includes: performing node seismic data monitoring of well gun excitation for well gun points with different line numbers and stake numbers in different gun groups. The node seismic data monitoring process of steps S301-309 can be performed separately for well gun points with different line numbers and stake numbers in different gun groups to obtain seismic data detection results, including whether the seismic data monitoring indicators meet the expected requirements and whether the mobile terminal detects the well gun excitation state.

[0114] Excite the well gun points with different line numbers and stake numbers. For example, 1 to 4 groups of guns are used to excite the well gun points with different line numbers and stake numbers. Recover 1 to 4 groups of mobile terminals and download the node seismic data monitoring results in the mobile terminals. Verify the gun points whose node seismic data monitoring results do not meet expectations and take timely response measures.
