Description
Technical Field
The application belongs to the technical field of seismic wave data acquisition, and particularly relates to a seismic wave acquisition method and system based on quantum measurement.
Background
The reflected wave seismic exploration and the scattered wave seismic exploration are two different seismic exploration methods, and the reflected wave seismic exploration is mainly used for detecting and explaining a subsurface reflection interface, namely an interface between different mediums, such as hydrocarbon reservoir, rock-mineral layer, salt dome boundary and the like; scattered wave seismic exploration mainly focuses on non-lamellar and non-uniform media such as underground scatterers, e.g., cracks, holes, rock and mineral anomalies, and the like. The reflected wave seismic acquisition and the scattered wave seismic acquisition have different signal characteristics, and the seismic signals recorded in the reflected wave seismic acquisition mainly comprise direct waves and reflected waves, and the amplitude and time information of the direct waves and the reflected waves can provide information about the position and the attribute of a subsurface interface. Whereas scattered wave seismic acquisition is primarily concerned with scattered wave signals, its amplitude and waveform variations can provide information about the location, shape and properties of the scatterers. But the reflected wave seismic acquisition and the scattered wave seismic acquisition use the same method and similar parameter configuration so far, a geometric state measurement technology is adopted, based on ray path calculation, the shot points and detectors are sparsely deployed on the earth surface, and the accurate homing of the underground common-center point (CMP) gather information is realized when the reflected wave received by each CMP gather travels.
Because the seismic waves are reflected, diffracted, scattered and other polymorphic propagation characteristics in the crust medium, the mode and parameters similar to the seismic acquisition of the reflected waves are not enough to describe complex geological structures, and complete seismic wave field signals cannot be acquired. The sparse and regular shot line and detector line acquisition mode is continuously used, so that the spatial sampling of small-scale media cannot be solved, and the acquisition of weak signals such as diffracted waves and scattered waves is not facilitated. Therefore, the scattered wave seismic exploration cannot be industrially applied to petroleum exploration and development, and the use of the method in metal exploration and engineering exploration is limited. Therefore, it is necessary to introduce seismic acquisition techniques other than geometric measurements, pushing scattered wave seismic exploration into more application areas.
Therefore, a method and a system for collecting seismic waves based on quantum measurement are provided to solve the problems existing in the prior art, which are the problems to be solved by those skilled in the art.

Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
Referring to fig. 1, the application discloses a seismic wave acquisition method based on quantum measurement, which adopts ultra-high density and ergodic acquisition, and specifically comprises the following steps:
s1: determining a seismic wave acquisition parameter design based on a quantum measurement principle;
s2: determining an earthquake acquisition implementation mode based on a quantum measurement principle;
s3: the excitation/receiving device is used for actually measuring and receiving the seismic signals;
s4: seismic data storage and device real-time positioning data transmission.
Further, S1 meets the requirements of ultra-high density space sampling and ergodic sampling of small-scale media.
Specifically, the seismic scattered wave acquisition area is determined by utilizing the early-stage geometrical seismic acquisition data through seismic processing, interpretation and geological analysis; considering the locality of the target and the seismic acquisition cost, the range is preferably 1+ or 10+ square kilometers.
Further, the requirement of ultra-high density space sampling and ergodic sampling of the small-scale medium are met, and the method specifically comprises the following steps: the method realizes the local random layout of small cells, small track pitches, small offset pitches, high coverage of near offset pitches, shot points and wave detection points.
Further, the specific content of S2 is: the method adopts a combination of superposition of a plurality of observation systems and a plurality of spatial sampling rates, adopts local random arrangement of the offset points under the condition of a line and beam-shaped observation system, adopts random arrangement of the offset points under the control of the density of the channels, adopts optimal arrangement of the offset points based on a compressed sensing technology and adopts delayed earthquake offset point arrangement based on big data acquisition to realize ultra-high density and ergodic acquisition aiming at local targets.
Specifically, as shown in fig. 2, in the polymorphic seismic wave acquisition schematic diagram of the seismic wave acquisition method based on quantum measurement disclosed by the application, an excitation unit and a receiving unit are arranged in an acquisition area, and the polymorphic seismic wave acquisition is realized by overlapping the seismic scattered wave acquisition and the geometric rule acquisition in a time-space domain; in order to control uncertainty of a system result caused by quantum measurement or guide the system result to acquire according to a certain seismic scattered wave, regular measurement and local random measurement are combined, and multi-observation system design, such as harness-shaped shots and detector point arrangement with a large offset distance (6000 meters), a large channel spacing (40 meters) and a large shot point spacing (80 meters) regular are adopted, and the multi-state seismic wave acquisition is realized by combining the small channel spacing (0-1000 meters), the small channel spacing (0-5 meters) and the local random shot point and detector point arrangement of the small shot point spacing (0-50 meters).
Specifically, the excitation unit is composed of a controllable earthquake focus or a well gun controlled by an explosion machine; the broadband excitation of the well cannon and the controllable seismic source can be realized, the excitation frequency needs to be expanded to 1.5-3Hz at the low frequency end, and the excitation frequency needs to be increased to 140-160Hz at the high frequency end, so that the broadband excitation exceeding 6 octaves is realized.
The receiving unit comprises node meters and acquisition stations, the node meters are used locally in a large scale and high density, the number of the node meters used per square kilometer is up to 104 or more, and the node meters are improved by 1-2 orders of magnitude compared with the conventional acquisition. Because the node instrument has high use density and small distance, new breakthroughs need to be made in the aspects of low noise, low power consumption, low cost, small volume, intensification and the like.
Further, a multi-observation system superposition and multi-space sampling rate combination is adopted, and the method specifically comprises the following steps: the superposition and multi-space sampling rate combination of the multi-observation system are realized by fusion of the three-dimensional seismic data acquired in the earlier stage or mosaic implementation.
Further, the local random layout of the offset points under the condition of the line and beam-shaped observation system is specifically as follows: the conventional harness-shaped observation system is improved, and the local random arrangement of the offset points under the condition of the harness-shaped observation system is realized by adopting the random half track distance or half running point distance.
Further, the shot points under the control of the shot channel density are randomly distributed, and the concrete steps are as follows: by determining the gun channel density in a unit area and adopting blocky pile-free construction, the random arrangement of gun-detecting points under the control of gun channel density is realized.
Specifically, in the acquisition process, the space sampling and the small cell coverage times are controlled by using the gun channel density, the excitation points and the detection points are distributed locally and randomly, the gun point distance and the detection point distance are unevenly changed in a fixed range, the small cell, the small channel distance, the small offset distance and the high coverage sampling of an acquisition area are realized, and the method further comprises the steps of performing multi-domain control in the seismic wave acquisition process by adopting the offset distance and the multiple coverage, and realizing near offset increase of the small cell coverage times, remote offset borrow of a large cell channel set and small cell channel number and energy balance. The generated common-center point gather has a space discrete characteristic, meets the requirement of multi-face element division, and can realize multi-face element division by the extracted CMP (common-center point) gather, generally selects 1/2 of the minimum dimension to be resolved as the optimal face element, and obtains seismic wave data.
Further, wave-particle two-dimension (wave-particle two) is an important feature of quantum measurement, the scale of a geological object can be infinitely subdivided in space, and theoretically, the space sampling interval of ground seismic measurement tends to be infinitely small, or continuous sampling density is achieved. The method is characterized in that the method is realized by combining two operation modes, namely ultra-dense or continuous sampling of a seismic space sampling interval, as shown in fig. 3 and 4, one mode is a mode of excitation/reception of a shot line and a detection line not strictly, the shot point spacing and the detection point spacing can be changed and uneven within a certain range according to a local random concept, the generated common center point gather has space discrete characteristics and meets the requirement of multi-face element division, so that two concepts of a basic face element and an optimal face element are generated, the basic face element refers to the sampling interval which can meet the minimum requirement of the space resolution, the sampling interval is generally equal to the regularly acquired face element, the optimal face element refers to the sampling interval which meets the optimal requirement of the space resolution, and 1/2 of the minimum resolution is generally selected. Secondly, the local random concept is that the shot point distance and the detection point distance can be changed in a certain range and are uneven, and because weak signals are overlapped for many times, the small bin division is ensured by taking the coverage times in the bin. The most convenient way to understand the lane density is two interrelated formulas:
lane density = number of face elements per unit area x number of coverage times (1)
Gun channel density = total gun number per unit area × total channel number (2)
The formula (1) shows that the lane density is mainly controlled by the number of surface elements in unit area, and the coverage times are formed by two parts of regular acquisition and random acquisition, so that the near offset weak signal enhancement is realized. The cells are divided according to 1 meter by 1 meter interval per square kilometer, and 100 tens of thousands of cells are total, if 100 times of coverage are needed, the lane density is 1 hundred million times per square kilometer. Formula (2) shows that the gun channel density is the product of the channel number received by each gun and the total gun number, and in order to realize multiple combination modes of 1 hundred million times per square kilometer of gun channel density, 1 ten thousand times of gun channel density can be combined with 1 ten thousand times of excitation, and also 10 ten thousand times of gun channel density can be combined with 1 thousand times of excitation, and multiple factors such as comprehensive technical evaluation, environmental protection requirement, equipment investment, material investment consumption and the like are needed.
Another important feature of quantum measurement is locality (localization), where seismic exploration cannot define the exact location of diffracted and scattered waves, but knows that it may occur on near offset gathers or self-excitation self-gathers. By adopting the control such as regional regular acquisition and local random acquisition data fusion, the near-bias high coverage can be realized, thereby being beneficial to the acquisition of polymorphic weak signals such as diffracted waves, scattered waves and the like and the enhancement of local signals.
Important features of quantum measurements also include superposition (superposition), where seismic acquisition may be done in one pass or in multiple passes. Under the quantum measurement concept, multiple seismic acquisitions are performed for a local target, and a shot density of 1 billion traces per square kilometer or more can be achieved. Meanwhile, weak movement in a limited space is realized aiming at multiple acquisitions of a specific target, time is used for exchanging high sampling density, the acquisition cost is reduced by time, and the physical realization of a quantum measurement technology in seismic exploration is ensured. As shown in fig. 5 and 6, it can be seen that the seismic wave acquisition performed by the method of the present application improves the accuracy of acquisition.
Unlike classical precision measurement methods, quantum measurement refers to the measurement itself being part of the physical system and having an impact on the state of the system. Quantum systems are used not only to describe the microscopic world but also to describe the macroscopic world, and research has thought that macroscopic measurements of a large system consisting of a large number of quantum systems in a certain state can be used as an inspection of quantum theory and measurement principles. For seismic exploration, the time sampling is usually in the order of meters, the space sampling is in the order of ten meters, and the seismic acquisition is improved by one order of magnitude according to the quantum measurement concept, which is equivalent to improving the seismic imaging accuracy by one order of magnitude.
Secondly, the crust structure and the earthquake acquisition form a macroscopic quantum system, the system has the characteristic of quantum superposition, namely, the crust structure can exist in various scale environments simultaneously before being measured, for example, crust media are described by different scales all the time, a drilling core is described as a micron level and a millimeter level, and a logging curve is sampled as a centimeter level and a decimeter level; the system has uncertainty characteristics, such as a reflection state of an interface when reflected wave measurement is carried out, a diffraction state of the interface or a medium continuity interruption position when diffracted wave measurement is carried out, and a scattering state of a particle body when scattered wave measurement is carried out; the system has a local characteristic, and can realize weak signal amplification through multidimensional enhancement by knowing the occurrence position of the seismic waves in a specific state; moreover, the system also has quantum measurement features, i.e. the measurement itself affects the result of the measurement. The polymorphic seismic acquisition based on quantum measurement can be realized by utilizing the characteristics of the quantum system.
In this embodiment, the wired acquisition station transmits the received information to the instrument center recording unit for recording, and the wireless node instrument is used for local reception and local recording and periodic recovery. The node instrument is used in combination with the acquisition station, and the node instrument used locally has new breakthroughs in the aspects of low noise, low power consumption, low cost, small volume and the like, and ensures that the dynamic range of the signal meets 120 dB.
