Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Considering that in the existing micro-motion exploration implementation process, time difference exists between data acquisition and data processing, data is generally acquired in the field, then data processing is carried out in the field, when professionals process the data in the field to find that the data is unqualified, acquisition devices are required to be rearranged in the field to acquire the data, and field operators often do not have enough professional ability to judge whether the acquired micro-motion data is qualified or not on site, so that exploration efficiency is low.
Based on the above, the embodiment of the invention provides a micro-motion exploration method and a micro-motion exploration system, which can alleviate the technical problems and effectively improve the micro-motion exploration efficiency. For the convenience of understanding the present embodiment, a micro-prospecting method disclosed in the present embodiment will be described in detail first.
Example 1
Referring to fig. 1, a flow chart of a micro-prospecting method according to an embodiment of the present invention is shown, and the method includes the following steps:
step S101, collecting micro-motion signals of a target line based on a preset micro-motion observation device.
In this embodiment, the micro-motion observation device is an acquisition device for acquiring micro-motion signals, and generally, the device includes an acquisition host, a signal transmission cable connected with the acquisition host, and a detector, where the detector is connected to the signal transmission cable and is arranged on a target measurement line at a preset interval. Here, the micro-motion observation device is arranged by a preset construction method, and micro-motion signals of the target measuring line are collected based on the arranged array.
In actual operation, the acquisition parameters of the work area where the target measuring line is located can be obtained in advance through an acquisition experiment so as to meet the requirement of acquisition depth. In this embodiment, the acquisition parameters of the micro-motion observation device are defaulted to meet the requirement of the acquisition depth.
Step S102, extracting the dispersion curve of the target measuring line in real time according to the micro-motion signal.
When the micro-motion signal of the target measuring line is acquired in real time, the acquired data is directly stored for processing in the industry, or the acquired original surface wave data is displayed on the acquisition host so as to be convenient for professionals to judge, but the mode requires an expert with higher professional ability to judge the condition of the data on site accurately, and an accurate and qualitative conclusion cannot be given; the data collected on site has great uncertainty, and the qualification rate of the collected data cannot be guaranteed.
In the method, after the micro-motion signals of the target measuring line are collected in real time, the micro-motion signals are automatically processed in real time on site, and the dispersion curve of the target measuring line is obtained through extraction. Here, the dispersion curve may be a dispersion curve of a speed-depth domain.
Step S103, judging whether the inching signal meets the preset condition or not based on the dispersion curve.
Here, the preset condition may be set by itself according to actual exploration requirements, for example, the condition may be set as a condition conforming to a basic exploration standard, or a condition of more stringent high requirements. Specifically, the form, the convergence degree, the number of the dispersion points, the distribution characteristics and the like of the dispersion curve can be limited, so as to screen the dispersion curve meeting the preset limiting condition.
Based on the dispersion curve extracted in step S102, whether the dispersion curve meets the requirement is judged according to a preset condition. In one or more possible embodiments, the preset conditions include: the trend of the micro-motion signal is converged integrally (no abrupt points exist), the trend of the micro-motion signal has slope change, the trend of the micro-motion signal has inflection points, and the number of the dispersion points of the micro-motion signal in a unit depth interval is not less than a preset point number. Therefore, when the extracted dispersion curve simultaneously meets the four conditions, the extracted dispersion curve is considered to meet the preset conditions, otherwise, the inching signal is determined not to meet the preset conditions.
Step S104, if the preset condition is not met, the micro-motion signal of the target measuring line is collected again based on the micro-motion observation device until the collected micro-motion signal meets the preset condition, and the micro-motion signal meeting the condition is stored as a qualified observation signal of the target measuring line.
If the extracted dispersion curve is judged not to meet the preset condition, namely the collected inching signal data is considered not to meet the requirement, at the moment, the inching signal of the target measuring line is collected again based on the inching observation device until the collected inching signal meets the preset condition. Here, the jog signal satisfying the preset condition is stored as a qualified observation signal of the target line, and thus, each saved raw data is effective data, which is also reliable observation data of the target line.
Therefore, the condition of data acquisition can be judged in real time on site, and qualified data of a target survey line can be acquired after each acquisition device is arranged, so that the acquisition device is not required to be arranged on the same survey line repeatedly for multiple times, the arrangement and acquisition time is saved, and the exploration efficiency is improved.
The micro-motion exploration method provided by the embodiment of the invention comprises the following steps: acquiring a micro-motion signal of a target survey line based on a preset micro-motion observation device; extracting the dispersion curve of the target measuring line in real time according to the micro-motion signal; judging whether the inching signal meets a preset condition or not based on the dispersion curve; and if the preset condition is not met, the micro-motion signal of the target measuring line is collected again based on the micro-motion observation device until the collected micro-motion signal meets the preset condition, and the micro-motion signal meeting the preset condition is stored as a qualified observation signal of the target measuring line. According to the method, the dispersion curve of the micro-motion signal is extracted in real time, whether the micro-motion signal meets the preset condition is judged, and the micro-motion signal is collected again when the micro-motion signal does not meet the condition until the observation signal meeting the condition is collected, so that the situation that the collection device is required to be rearranged in the field and the data is collected when the data is found to be unqualified in the processing data in the industry due to the fact that whether the collected data is qualified in the collection field in the conventional micro-motion exploration is relieved, and the micro-motion exploration efficiency is improved.

Step S201, collecting micro-motion signals of a target line based on a preset micro-motion observation device.
Step S202: and extracting the dispersion curve of the target measuring line in real time according to the micro-motion signal.
In this embodiment, the preset micro-motion observation device may automatically extract the dispersion curve of the target line in real time according to the micro-motion signal, and simultaneously display the dispersion curve of the target line in real time.
In actual operation, the exploration depth of the target line, the change of the geological interface of the target line and the formation speed change of the target line can be obtained according to the dispersion curve of the target line. Then, judging whether the exploration depth of the target measuring line, the change of the geological interface of the target measuring line and the change of the stratum speed of the target measuring line meet exploration requirements, if so, continuing to execute the following step S203; if not, the exploration program is adjusted.
In one embodiment, the method for adjusting the exploration scheme is to adjust the construction method in real time, wherein the method comprises the step of adjusting the size of the array or the scale of the array in real time so as to improve the exploration depth and meet the exploration requirement.
Step S203: judging whether the dispersion curve meets the characteristic requirement of a preset standard dispersion curve or not; if yes, step S205 is performed, otherwise step S204 is performed.
In this embodiment, the step of determining whether the dispersion curve meets the characteristic requirement of the preset standard dispersion curve includes: judging whether the dispersion curve has the following four characteristics at the same time: the whole of the dispersion curve is converged, the dispersion curve has slope change, the dispersion curve is provided with a folding point, and the number of dispersion points in a unit depth interval of the dispersion curve is not less than the number of preset points; if yes, determining that the dispersion curve meets the characteristic requirement of the preset standard dispersion curve, otherwise, determining that the dispersion curve does not meet the characteristic requirement of the preset standard dispersion curve.
In one embodiment, the dispersion curve is a velocity-depth domain curve.
Step S204: and determining that the inching signal does not meet the preset condition.
In this embodiment, when it is determined that the micro-motion signal does not meet the preset condition, the micro-motion signal of the target line is collected again based on the micro-motion observation device until the collected micro-motion signal meets the preset condition.
Step S205: and determining that the inching signal meets a preset condition.
Step S206: and storing the micro-motion signal meeting the preset condition as a qualified observation signal of the target measuring line.
In this embodiment, after the collected micro-motion signal meets the preset condition and the micro-motion signal meeting the preset condition is stored as the qualified observation signal of the target line, the method further includes: and obtaining the exploration profile of the target survey line based on inversion of the qualified observation signals.
In another possible implementation manner, the dispersion curve is a speed-depth domain curve, and when the speed-depth domain curve meets the characteristic requirement of a preset standard dispersion curve, after storing the inching signal meeting the preset condition as a qualified observation signal of the target line, the exploration profile of the target line is obtained according to inversion of the speed-depth domain curve corresponding to the qualified observation signal.
The micro-motion exploration method provided by the embodiment of the invention comprises the following steps: acquiring a micro-motion signal of a target survey line based on a preset micro-motion observation device; extracting the dispersion curve of the target measuring line in real time according to the micro-motion signal; judging whether the dispersion curve meets the characteristic requirement of a preset standard dispersion curve or not; if yes, determining that the inching signal meets the preset condition, otherwise, determining that the inching signal does not meet the preset condition. And if the preset condition is not met, the micro-motion signal of the target measuring line is collected again based on the micro-motion observation device until the collected micro-motion signal meets the preset condition, and the micro-motion signal meeting the preset condition is stored as a qualified observation signal of the target measuring line. According to the method, the dispersion curve of the micro-motion signal is extracted in real time, whether the dispersion curve meets the characteristic requirement of the preset standard dispersion curve is judged, and the micro-motion signal is automatically collected again when the condition is not met until the observation signal meeting the condition is collected, so that the micro-motion exploration efficiency is further improved.
