Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, in the seismic exploration, acquisition and processing link, field technicians and geophysical prospecting supervisors generally adopt a 'phase surface method' to analyze and evaluate the single shot record quality, shallow, medium and deep seismic data lack corresponding geological horizon concepts to cause unclear horizons of a target layer, analysis of the single shot record quality, judgment of geological task completion conditions required by the first party and data processing and analysis lack pertinence and reliability, and research on data analysis with geological horizon viewpoints on the single shot records is less at present. Based on the current situation, the application provides a method for calibrating a single shot record layer position.
In the actual seismic exploration acquisition and processing link, as shown in fig. 1, simple ray tracing is performed on a three-layer layered model, symmetrical arrangement receiving is adopted in the middle of the ground, and a single shot record and a horizontal stacking time section are obtained. The method and the device are used for carrying out horizon calibration on the single shot record based on the horizontal superposition time profile.
As shown in fig. 2, a method for calibrating a single shot record horizon specifically includes the following steps:
s101: and calibrating the horizon of the reflecting layer of the horizontal stacking time section through the vertical seismic section, the acoustic wave synthetic record and the well drilling data.
Vertical Seismic Profiling (VSP) is a method of observing the Seismic wavefield in a well and placing geophones at different depths in the well to record the Seismic signals generated by a ground Seismic source.
In one embodiment, the reflector horizons of the offset time profile are calibrated from the VSP, sonic synthetic logs, and the drilling geological horizons, and the reflector horizons of the horizontal overlay time profile are further calibrated using the horizons of the offset time profile.
S102: and (4) marking the terrain lines of the horizontal superposition time section on the single shot record in an equal proportion.
After the horizon of the horizontal overlay time profile is determined in step S101, the terrain line on the horizontal overlay time profile is marked on the shot-log, and the scale of the horizontal overlay time profile and the longitudinal direction (stratigraphic section) of the shot-log are adjusted to be consistent, for example, a depth of 2 cm on the horizontal overlay time profile represents an actual depth of 200 m, and then a depth of 2 cm on the shot-log also represents 200 m of the actual depth.
S103: and determining the corresponding position of the minimum point in the single shot record in the horizontal superposition time section.
Finding a minimum point (namely a self-excited point) in the shot record, then determining the position of the minimum point on the horizontal superposition time section, and locking the position relation of the shot record and the horizontal superposition time section by taking the minimum point as a standard point. As shown in fig. 1, the position of the shot point recorded by a single shot is marked at the corresponding position on the terrain line of the horizontal superposition time section, and the geological layer on the horizontal superposition time section is the geological layer of the reflection layer of the single shot. Geological layers of seismic reflection layers TR1, TR2 and TR3 of the seismic single shot record are chalky line (K), dwarfism (J) and triassic line (T) bottom boundary reflection layers respectively.
S104: and marking the horizon of the horizontal superposition time section on the single shot record minimum point reflecting layer.
In a specific embodiment, because the horizontal superposition time section reflecting layer is marked with the layer position, the position relation between the single shot record and the horizontal superposition time section is determined by using the minimum point, and then the layer positions on the horizontal superposition time section are projected into the single shot record minimum point reflecting layer one by one, namely the calibration of the single shot record layer position is completed.
The execution main body of the method shown in the figure 2 can be a server, a PC and a mobile terminal, the method accurately calibrates the geological horizon of each reflection horizon on a single shot record by introducing the horizon of the explained horizontal superposition time section in a work area to the single shot record, and is beneficial to field technicians and geophysical prospecting supervision to analyze the quality of the single shot record, the size of the reflection energy of a target layer and whether the reflection of the target layer is obtained in a targeted manner, so that the influence of the surface underground geological conditions on the quality of the single shot record, the reasonability of the excitation capacity of the well depth dosage and the influence of the surface lithology on the single shot can be further analyzed, and the smooth completion of the acquisition and processing tasks is ensured.
In one embodiment, as shown in FIG. 7, calibrating horizontal stack time section reflector horizons from vertical seismic sections, sonic synthetic logs, and well data comprises:
s201: and calibrating the reflection layer horizon of the migration time section through the vertical seismic section, the acoustic synthetic record and the well drilling data.
In one embodiment, as shown in FIG. 3, the reflector layer horizon of the offset time profile is calibrated using VSP, sonic synthetic logs, and well data, including whisker bottom, fly-top, sun bottom, etc.
S202: and determining horizons of the horizontal superposition time profile according to the horizons of the offset time profile.
In a specific embodiment, after completing the offset time profile horizon calibration, as shown in fig. 3, the horizon projection calibration in fig. 3 is performed into the horizontal overlay time profile in fig. 3, and the horizontal overlay time profile horizon calibration is completed.
In one embodiment, as shown in fig. 8, the marking of the topographic line of the horizontal stack time section on the single shot record in equal proportion comprises:
s301: and taking the terrain line of the horizontal superposition time section as a zero time line of the single shot record.
In one embodiment, as shown in fig. 4, the terrain line of the horizontal stack time section is taken as the 0-time line of the shot record, and recorded on the shot record and the horizontal stack time section.
S302: the longitudinal scale of the horizontal superposition time section is kept consistent with the longitudinal scale of the single shot record.
In one embodiment, as shown in FIG. 4, the horizontal stack time profile is scaled to coincide with the longitudinal (stratigraphic profile) scale of the single shot record, e.g., a depth of 2 cm on the horizontal stack time profile represents an actual depth of 200 meters, and then a depth of 2 cm on the single shot record represents 200 meters from the actual depth.
In one embodiment, as shown in fig. 8, marking a horizon of a horizontal overlay time profile onto a single shot record minima reflection layer comprises:
s401: and placing the minimum point on the horizontal superposition time section and the minimum point in the single shot record on the same horizontal line.
In a specific embodiment, after the minimum point in the shot record and the position of the minimum point in the horizontal superposition time section are determined, the position relation between the shot record and the horizontal superposition time section is determined and adjusted to be longitudinally corresponding, namely the minimum point is on the same horizontal line.
S402: and mapping the horizon on the horizontal superposition time section into the single shot record one by taking the minimum point on the horizontal superposition time section as a center.
In one embodiment, as shown in FIG. 5, in two-dimensional seismic exploration, the horizontal stack time profile horizon is horizontally projected into the single shot record minimum point reflection layer, i.e. single shot record horizon calibration is performed. If the three-dimensional seismic exploration is carried out, as shown in fig. 6, the horizontal stacking time profile horizon is horizontally projected to a near shot record in a single shot record, namely, the three-dimensional single shot record horizon is calibrated, and a geological horizon cannot be reliably determined by a far shot record. Because the receiving arrangement of the near shot is equivalent to a two-dimensional survey line, the shot point and the demodulator probe are on the same line, and the receiving arrangement of the far shot and the demodulator probe are not on the same line, the time delay is not observed in a longitudinal direction.
In one embodiment, the specific method for calibrating the single shot record horizon using the seismic horizontal stack time section may be as follows:
the method comprises the steps of firstly determining a reflection horizon of a horizontal stack time section, then calibrating the horizon of a seismic reflection layer of the offset time section by utilizing VSP (vertical seismic profiling), acoustic synthetic record and drilling geological horizon, and projecting the calibrated horizon onto the horizontal stack time section as shown in figure 3. And then determining the position of the shot record in the horizontal superposition time section, taking the terrain line of the horizontal superposition time section as the 0 time line of the shot record, and then adjusting the shot record and the horizontal superposition time section to ensure that the longitudinal proportion of the shot record and the horizontal superposition time section is consistent. Finally, calibrating the position of the single shot record, and horizontally projecting the position of the horizontal superposition time section into the single shot record after determining the minimum point of the single shot record and the position of the minimum point in the horizontal superposition time section in the two-dimensional seismic exploration process, thereby completing the calibration of the position of the single shot record; and if the horizon is calibrated in the three-dimensional single shot record, horizontally projecting the horizon of the horizontal superposition time section to a near shot record in the three-dimensional single shot record by using the same method as the two-dimensional single shot record to finish calibration.
Based on the same inventive concept, the embodiment of the present application further provides a device for calibrating a single shot record layer, which can be used to implement the method described in the above embodiment, as described in the following embodiment. The principle of solving the problems of the device for calibrating the single shot record layer position is similar to that of the method for calibrating the single shot record layer position, so the implementation of the device for calibrating the single shot record layer position can refer to the implementation of the method for calibrating the single shot record layer position, and repeated parts are not repeated.
