Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In view of the fact that in the prior art, a complex structural band cannot form clear and accurate seismic imaging data, so that geological knowledge of evolution of the complex structural band formation cannot be improved, the embodiment of the application provides a specific implementation of a seismic data imaging method based on an indoor sand box, and the method specifically comprises the following steps of:
step 100: the indoor sand box is constructed to simulate the geological structure of the target work area.
Specifically, according to the actual size of the target work area, the size of the indoor sand box is reduced according to a preset proportion, and experimental sand bodies are paved according to the thickness and the form of the sedimentary stratum of the target work area. It will be appreciated that the physical modeling of the geological structure of the work area at the bottom of the work using a flask allows the geological data of the desired work area obtained by conventional methods to be approximated at a lower cost.
Step 200: and scanning the indoor sand box and collecting ultrasonic data of the indoor sand box to establish a construction-speed model of the target work area.
It can be understood that the construction physical simulation experiment result based on the industrial CT can accurately provide construction models in different evolution stages, on the basis, the ultrasonic wave is utilized to simulate field artificial explosion in a laboratory, and model reflection signals are acquired and processed and imaged, so that a speed model is established, and model support is provided for complex construction belt seismic imaging.
Step 300: and generating seismic imaging data of the target work area according to the construction-speed model.
Seismic imaging is a technique that uses seismic data to invert the material properties of a subsurface structure and parse it layer by layer to map its image. The theoretical basis on which the imaging is based is generally classified into radiation equation-based tomography and wave equation-based tomography. While seismic imaging data built based on the build-up-speed model of the indoor flask formation can greatly simplify earlier work, such as: parameterization of the model, forward calculation of theoretical values of the properties of the underground medium (ray tracing, waveform fitting), inversion and image reconstruction, evaluation of inversion results (resolution analysis) and the like.
From the above description, it can be seen that the seismic data imaging method based on the indoor sand box provided by the embodiment of the application firstly constructs the indoor sand box to simulate the geological structure of the target work area; and then, organically combining a structural deformation physical simulation technology based on an indoor experiment sand box with an earthquake imaging physical simulation technology, constructing a structure-speed model of the target block, and accurately describing the underground geological structure of the target block based on the model, so that the earthquake imaging quality can be greatly improved, and the underground geological structure of the target block can be accurately described.
In one embodiment, referring to fig. 2, step 100 specifically includes:
step 101: quartz sand of different particle sizes and different densities are arranged inside the water tank to construct the indoor sand box.
The water tank in step 101 is a sand box main body, and is used for fixing quartz sand in the sand box main body, and simulating different stratum in a target work area by adopting quartz sand with different grain sizes and different densities.
Step 102: and calculating the deformation rate and the deformation amount of the indoor sand box according to the shortening amount, the tension amount, the shortening rate and the tension speed of the geological structure.
Step 103: and simulating the geological structure according to the deformation speed, the deformation amount and the quartz sand by a preset scale.
And (3) paving an experimental sand body according to the deformation speed and the deformation amount obtained in the step (102) and according to the thickness and the form of the sedimentary stratum of the target work area according to a preset scale so as to simulate the geological structure. Preferably, the formation subjected to overpressure is provided with a grain size of fine dry quartz sand, for example 40 mesh, and other atmospheric formations are provided with a grain size of coarse dry quartz sand, for example 20 mesh. It can be appreciated that the underground geologic structure of the target work area can be accurately simulated by simulating the geologic structure according to the deformation speed, the deformation amount and the quartz sand at a preset scale.
In one embodiment, referring to fig. 3, step 200 specifically includes:
step 201: and extruding the sand body in the indoor sand box.
The extrusion sand body can simulate the geological structure movement suffered by the target work area, and in addition, the liquid contained in the sand body can be extracted to simulate the underground geological change of the target work area caused by the production of an oil well in the target work area, and likewise, the liquid can be injected into the sand body to simulate the underground geological change of the target work area caused by the injection production of a water well in the target work area.
Step 202: and scanning the extruded sand body by using an industrial CT scanning method to establish a construction model of the target work area.
The construction physical simulation experiment result based on the industrial CT can accurately provide construction models and speed models in different evolution stages, and provide model support for complex construction belt seismic imaging.
By utilizing the theory of medical X-ray CT, the geophysical prospecting technology of the distribution condition of the underground physical parameters is investigated in detail by adopting the construction physics simulation technology of industrial CT, so that the material properties of the underground structure are inverted by utilizing the seismic data, and the images are analyzed and drawn layer by layer. The obtained structural model can accurately determine the structure and local non-uniformity of a target work area.
Step 203: and (3) carrying out ultrasonic data acquisition on the extruded sand body by using an ultrasonic source method so as to establish a speed model of the target work area.
The method is characterized in that ultrasonic waves are utilized to simulate field artificial explosion in a laboratory, reflected signals formed by sandstone with different particle sizes and different densities in a sand box are collected and processed, so that a target speed model is built, the actual seismic data processing and interpretation are guided, and the seismic imaging quality and interpretation accuracy are improved.
Step 204: the build-speed model is generated from the build model and the speed model.
The construction model established in the step 202 is combined with the velocity model in the step 203, so that a construction-velocity model can be generated, namely, a construction deformation physical simulation technology based on an indoor experimental sand box and an earthquake imaging physical simulation technology are organically combined, and thus, the geological structure form of a target work area and the velocity information of the underground structure of the target work area can be accurately described.
In one embodiment, referring to fig. 4, step 300 specifically includes:
step 301: and generating the seismic imaging data of the target work area according to the construction-speed model by using a chromatographic migration speed method.
It will be appreciated that the use of the chromatographic migration velocity method can eliminate the effects of dip angle formation, migration distance and heterogeneous medium propagation in pre-stack seismic data, but that this method requires an accurate formation-velocity model that is sufficiently satisfied by the formation-velocity model generated in step 200.
To further illustrate the scheme, the application takes the southerly edge deep layer of the Pascal basin and the hero ridge region of the Qidamu basin as examples, and provides a specific application example of the seismic data imaging method based on the indoor sand box, wherein the specific application example specifically comprises the following content, and the content is shown in FIG. 5.
S1: an initial experimental model is prefabricated in a water tank.
The physical simulation of the structural deformation of the experimental sand box is that loose quartz sand is used as a common material, and the structural deformation of underground real rock is simulated when the material is broken by external stress and meets the breaking criterion of the rock in the nature. According to the principle of a physical simulation experiment, an actual geological model is prefabricated into an initial experiment model formed by different quartz sand in a water tank according to a certain similarity ratio. And calculating the deformation rate and the deformation amount under the experimental conditions according to the actual geological shortening/stretching tensor and the shortening/stretching rate.
S2: CT scanning is carried out on the experimental model.
Because quartz sand with different densities is selected to represent different rock layers underground in the experimental process, the transmission speed of ultrasonic waves in the quartz sand with different densities is different, and an accurate structure-speed model can be established according to the structure deformation CT scanning image.
According to the actual geological conditions and research requirements, a certain time is needed in the experimental process, the physical simulation experimental result of the structural deformation is scanned by using industrial CT (the scanning result is shown in figure 6), and meanwhile, the speed of ultrasonic wave propagation in quartz sand is used for establishing a structural-speed model of the structural deformation (see figure 7).
S3: seismic data acquisition and imaging of the structural deformations are performed.
And carrying out seismic data acquisition-processing imaging on a physical simulation experiment of the structure after the industrial CT scanning is completed, wherein the imaging result is shown in figure 8.
Wave impedance interfaces can be generated between different materials, so that reflected signals constructing a deformation physical simulation experimental model can be acquired by utilizing a seismic physical simulation technology, and seismic imaging can be performed. In the oil and gas exploration of a practical complex structural area, because the structural deformation is complex, the establishment of an accurate structural-velocity model is very difficult, and the later seismic imaging processing-interpretation difficulty is very high, the accurate structural-velocity model provided by the structural deformation physical simulation experiment can improve the seismic imaging quality of the complex structural area.
The method is applied to complex construction areas such as the southern edge deep layer of the quasi-Song basin and the hero-ridge area of the Qidamu basin to improve geological structure recognition and imaging quality, and 5 wind risk wells and pre-exploratory wells are deployed on the technology, wherein the southern edge and the west Duan Gao of the quasi-Song basin are used for exploratory 1 well to obtain industrial oil gas flow of thousands of days.

Specifically, the construction physical simulation experiment result based on the industrial CT can accurately provide construction models and speed models in different evolution stages, an accurate construction-speed model (CT monitoring) in the deformation process of the complex construction is established, and the seismic data acquisition-imaging of the model is completed, so that model support is provided for the seismic imaging of the complex construction, the method has important significance for the advancement of the oil and gas exploration technology of the complex construction, and the production cost can be greatly reduced compared with the conventional method.
