[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0044] Method Embodiment
[0045] Reference Figure 1 , shows a flowchart of a method for pre-evaluating single shot data of seismic exploration according to an embodiment of the present invention, which may specifically include the following steps:
[0046] Step 101, obtaining background energy information of a detection point corresponding to a target shot point, wherein the background energy information is used to reflect the background energy before the seismic exploration signal excited at the target shot point reaches the detection point;
[0047] It is understandable that when collecting seismic data, artificial methods are usually used to excite seismic waves as seismic exploration signals, and detectors arranged at multiple detection points are used to record the propagation of seismic waves underground, so as to explore geological characteristics based on the propagation conditions (also known as seismic data, single shot data, etc.).
[0048] Among them, the shot point refers to the location where the seismic exploration signal is excited, and the detection point refers to the receiving point of the seismic exploration signal, which is determined according to the propagation range of the seismic exploration signal. When collecting seismic data, a detector can be arranged at the detection point to receive the seismic exploration signal. Among them, one detector is usually set at one detection point.
[0049] Background energy information is data reflecting background energy collected by the detectors arranged at the detection points, such as noise signals, radiation signals, etc. Moreover, in the actual seismic exploration process, the background energy of the detection point can be calculated by the background energy information, and then the interference situation of the detection point can be judged according to the background energy.
[0050] In an embodiment of the present invention, in order to achieve a pre-evaluation of single shot data for a target shot point, before the seismic exploration signal excited at the target shot point reaches the detection point, the background noise, signal and other background energy information of the detection point are collected by the detector to reflect the signal interference situation at the location of the detection point, and then the signal interference situation of each detection point corresponding to the target shot point is comprehensively considered to pre-evaluate the quality of the seismic data collected based on the target shot point. Based on the pre-evaluation result for the target shot point, the seismic data acquisition method can be adjusted. For example, if the pre-evaluation result is poor, the detection point and / or the target shot point is set at a position with less interference, so as to facilitate taking targeted measures to ensure the quality of seismic data when collecting seismic data in the field.
[0051] Step 102: Based on preset conditions and the background energy information, determine whether the channel where the detection point is located is an interference channel; wherein the background energy information of a detection point constitutes a channel where the detection point is located, and the background energy of the detection point reflected by the interference channel meets the preset conditions.
[0052] Among them, before the seismic exploration signal excited at the target shot point reaches the detection point, a series of background energy information collected at a detection point constitutes a channel where the detection point is located. Similarly, when collecting seismic data, after the target shot point is excited, the detection point corresponding to the target shot point receives the seismic signal information; 1 detection point corresponds to 1 channel, and the detection point forms single-shot data after receiving the seismic signal. There are as many single-shot data channels as there are detection points corresponding to the shot point receiving the seismic signal.
[0053] Dividing the detection point channel facilitates the identification of the detection point and the corresponding detector position to distinguish other detection points. Correspondingly, the interference channel refers to the detection point channel where the background energy of the detection point meets the preset conditions. Of course, the preset conditions can be determined according to the actual situation during seismic data acquisition.
[0054] In an optional embodiment of the present invention, the preset condition may refer to a preset threshold value. If the background energy of the detection point within the preset time period is greater than the threshold value, it can be determined that the channel where the detection point is located is an interference channel. If the background energy of the detection point within the preset time period is less than or equal to the threshold value, it can be determined that the channel where the detection point is located is normal.
[0055] Different from the above method of determining whether the channel where the detection point is located is an interference channel by setting a threshold value, taking into account the range interference of interference sources such as urban areas, factories and mines, in order to ensure that the distribution of interference channels is fully obtained, in another optional embodiment of the present invention, a threshold value can be used to make a preliminary judgment on the channel where the detection point is located, and then the interference range of the interference source is determined based on the interference channel determined by the preliminary judgment, and then the interference channel is further determined based on the detection points covered in the interference range.
[0056] Step 103: Determine the interference channel ratio according to the number of interference channels corresponding to the target shot points and the number of detection points.
[0057] The target shot point corresponds to multiple detection points, and accordingly, the target shot point also corresponds to multiple detection point channels. By calculating the ratio of the interference channel to the number of detection points, the signal interference situation when collecting seismic data based on the target shot point can be fully reflected.
[0058] Step 104: Determine a preliminary evaluation result of the single shot data of the target shot point based on a preset ratio threshold and the interference channel ratio.
[0059] Among them, the preset ratio threshold is used to reflect the interference degree of the single shot data of the target shot point, and at the same time, the interference degree affects the quality of the collected seismic data. Therefore, the data quality of the single shot data of the target shot point can be determined by comparing the interference channel ratio with the ratio threshold, that is, the pre-evaluation result. The specific ratio threshold can be determined according to the actual situation during seismic data collection, and can be determined by different quality levels, which is not limited in this application.
[0060] Through the above method, the present invention realizes the quantitative evaluation of the influence of external interference sources on data, improves the work efficiency of pre-evaluation of seismic exploration single-shot data and the accuracy of evaluation results, and provides reliable data support for seismic acquisition quality control and anti-interference work.
[0061] Furthermore, the proportion of interference channels can not only measure the intensity of external interference, but also the distribution of detection points corresponding to the interference channels can reflect the scope of interference. At the same time, the proportion of interference channels can also be used to predict the quality of data in advance. Based on the pre-evaluation results of single-shot data of the shot point, it helps technicians to take targeted adjustment measures to ensure the quality of seismic data during field acquisition of seismic data, thereby improving the quality of seismic data and laying a good data foundation for the subsequent processing and interpretation of seismic data.
[0062] Optionally, the interference channel includes a first interference channel and a second interference channel; and the step 102 of determining whether the channel where the detection point is located is an interference channel based on a preset condition and the background energy information may include:
[0063] Step S11, obtaining location information of interference sources;
[0064] Step S12, based on a preset energy threshold and the background energy information, determining a first interference channel corresponding to the target shot point from the channel where the detection point is located; the background energy of the detection point reflected by the first interference channel is greater than the energy threshold;
[0065] Step S13, determining the interference range of the interference source according to the position information of the detection point corresponding to the first interference channel and the position information of the interference source;
[0066] Step S14: determine the channels where all detection points within the interference range are located as second interference channels.
[0067] The preset energy threshold is used to determine the interference degree of the detection point, which can be determined according to the actual situation during seismic data collection. Specifically, if the background energy of the detection point is greater than the preset energy threshold, the channel where the detection point is located is determined to be an interference channel, that is, the first interference channel; if the background energy of the detection point is less than or equal to the preset energy threshold, the channel where the detection point is located is determined to be normal.
[0068] At the same time, taking into account the range interference of interference sources such as urban areas, factories and mines, in order to ensure that the distribution of interference channels is fully obtained, after the first interference channel is preliminarily determined using the preset energy threshold, it is necessary to determine the interference range based on the location information of the detection points corresponding to the first interference channel and the location information of the interference source. At the same time, in order to avoid missing the detection points that are severely interfered, the channels where all the detection points corresponding to the detection points within the interference range are located can be determined as interference channels, that is, the second interference channels. Confirming the interference channels from the two aspects of energy threshold and interference range helps to fully understand the interference situation of the detection points and reduce the deviation of seismic data acquisition.
[0069] As an example, in actual seismic data collection construction, survey detectors are laid in advance near some interference sources. The present invention can select the background noise at a certain moment to project and display on a plane to obtain a geographic information map based on the background noise record received by the survey detector, and analyze the signal strength or background energy obtained by detectors at different distances in combination with the GIS base map. When the signal strength or background energy is less than a certain threshold after exceeding a certain distance, the influence range of the interference source is determined, and the channel where the detection point is located within its influence range can be determined as the interference channel. Among them, the GIS file is used to reflect the geographic feature information of the target area.
[0070] Reference Figure 2 A geographical information map reflecting the interference range provided by the embodiment of the present invention is shown. Among them, the solid circle represents the interference source, the dotted circle represents the interference range, and the rectangle represents different detection points. In the example of the present invention, the channel where the detection point with a background energy of more than 40 is located can be determined as the first interference channel, and then the interference range is determined based on the first interference channel. At the same time, since the determined interference range includes the detection points with a background energy between 20-40, in order to avoid the omission of the detection points with a higher degree of interference, the channel where the detection point with a background energy between 20-40 is located is also determined as the interference channel, that is, the channels where all the detection points within the interference range are located are determined as the second interference channel.
[0071] Optionally, the ratio threshold includes a first ratio threshold, and the step 104 of determining the pre-evaluation result of the single shot data of the target shot point based on the preset ratio threshold and the interference channel ratio includes:
[0072] Step S21: if the interference channel ratio is greater than the first ratio threshold, determining that the pre-evaluation of the single shot data of the target shot point is unqualified;
[0073] Step S22: If the interference channel ratio is less than or equal to the first ratio threshold, it is determined that the single shot data of the target shot point is qualified.
[0074] When only considering whether the single shot data is qualified or not, the single shot data can be pre-evaluated by presetting a first ratio threshold, that is, when the interference channel ratio is greater than the first ratio threshold, it can be considered that the seismic data acquisition based on the target shot point will be affected by more serious interference, and the single shot data of the target shot point is unqualified; when the interference channel ratio is less than or equal to the first ratio threshold, it can be considered that the seismic data acquisition based on the target shot point will be affected by less interference, and the single shot data of the target shot point is qualified.
[0075] Optionally, the ratio threshold includes a second ratio threshold and a third ratio threshold, and the second ratio threshold is less than the third ratio threshold; the step 104 of determining the pre-evaluation result of the single shot data of the target shot point based on the preset ratio threshold and the interference channel ratio includes:
[0076] Step S31, if the interference channel ratio is less than the second ratio threshold, determining that the interference level of the single shot data of the target shot point is the first level;
[0077] Step S32: if the interference channel ratio is greater than or equal to the second ratio threshold and less than or equal to the third ratio threshold, then determining that the interference level of the single shot data of the target shot point is the second level;
[0078] Step S33: if the interference channel ratio is greater than the third ratio threshold, determining that the interference level of the single shot data of the target shot point is the third level;
[0079] The first level is lower than the second level, and the second level is lower than the third level.
[0080] Taking the quality of single shot data into consideration, the interference level of single shot data can be evaluated in multiple levels according to the interference channel ratio.
[0081] As an example, if the acquisition production adopts a three-level evaluation, the second ratio threshold and the third ratio threshold can be set according to specific production requirements, and the second ratio threshold is less than the third ratio threshold. If the interference channel ratio is less than the second ratio threshold, it can be considered that the interference level is relatively light when the seismic data is collected based on the target shot point, and the seismic data collected based on the target shot point can be set as the first-level external interference product; if the interference channel ratio is between the ratio thresholds (including the case where the interference channel ratio is equal to the second ratio threshold or the third ratio threshold), it can be considered that the interference level is deeper when the seismic data is collected based on the target shot point than the first-level external interference product, but the seismic data collected based on the target shot point can still be used for oil seismic exploration and can be set as the second-level external interference product; if the interference channel ratio is greater than the third ratio threshold, the seismic data collected based on the target shot point cannot be used for oil seismic exploration and can be set as a waste product of external interference.
[0082] Through the above method, a quantitative evaluation of the impact of external interference sources on data is achieved, which reduces the labor intensity of manually estimating the impact of interference sources on data quality, improves work efficiency, and supports seismic acquisition quality control work.
[0083] Optionally, the background energy information includes a sample signal collected by a detector arranged at the detection point; before determining whether the channel where the detection point is located is an interference channel based on the preset condition and the background energy information, the method further includes:
[0084] The background energy of each detection point is calculated based on the sample point signal.
[0085] The sample signal refers to the signal at different time points collected by the detector set at the detection point within a preset time period, which is used to reflect the signal change of the detection point within the preset time period. The preset time period is the time period before the seismic exploration signal excited at the target shot point reaches the detection point. After collecting the sample signal of each detection point corresponding to the target shot point, the background energy of the corresponding detection point can be calculated based on a sample signal contained in the channel where the detection point is located, and then the interference channel can be determined based on the background energy.
[0086] Of course, in addition to the above method of calculating the background energy based on the collected sample point signals, the background energy information of the detection point can also be directly obtained through a detector or other equipment, and the present invention is not limited to this.
[0087] Optionally, the background energy includes background noise energy of a single detection point before the seismic exploration signal excited at the target shot point reaches the detection point.
[0088] Among them, before the seismic exploration signal excited at the target shot point reaches the detection point, the background noise energy of a single detection point can also be called single-channel pre-first-arrival energy, which specifically refers to the background noise energy of the detection point reflected by the channel where the single detection point is located.
[0089] Optionally, the background noise energy can be expressed as:
[0090]
[0091] Wherein, E represents the background noise energy, i represents the channel where the i-th detection point is located, a represents the amplitude of the sample signal, n represents the number of samples corresponding to the channel where each detection point is located, and K represents the conversion coefficient.
[0092] As shown in formula (1), the single-channel pre-arrival energy can be obtained by calculating the RMS value of the amplitude of the sample signal and multiplying it by the conversion coefficient. The sample signal can be a voltage signal collected by the detector, and K can be a conversion coefficient converted to a voltage value.
[0093] Optionally, the single-shot environmental noise value can be obtained by accumulating the single-channel pre-arrival energy of each detection point and then averaging it.
[0094] In summary, the present invention provides a method for pre-evaluation of single-shot data in seismic exploration. After obtaining the background energy information of the detection point corresponding to the target shot point, it can be determined whether the channel where the detection point is located is an interference channel based on preset conditions and the background energy information. Then, according to the number of interference channels corresponding to the target shot point and the number of detection points, the proportion of interference channels is determined, and then based on the preset ratio threshold and the proportion of interference channels, the pre-evaluation result of the single-shot data of the target shot point is determined. Through the above method, the present invention realizes the quantitative evaluation of the degree of influence of external interference sources on the data, improves the work efficiency of pre-evaluation of single-shot data in seismic exploration and the accuracy of evaluation results, and provides reliable data support for seismic acquisition quality control and anti-interference work.
