Description

Technical Field

[0001] The present invention belongs to the field of onshore seismic exploration, and specifically relates to a GIS platform and seismic acquisition information linkage method, and an excitation point design method and system. Background Art

[0002] As the exploration and development of oil and gas fields gradually deepen, the exploration targets become more complex and more concealed. Harsh surface conditions, complex underground structures, and complex reservoir spaces place higher and higher demands on geophysical acquisition technology. For typical loess hilly gully areas, the terrain is undulating, the height difference varies greatly, and the surface structure is extremely complex. The difficulty of seismic acquisition in this type of area is that the surface absorption attenuation is extremely serious. It is necessary to determine the depth of the excitation well according to the changes in the drill core and to carry out fine excitation point design according to the principle of "opening trenches, expanding plateaus, and cutting slopes" to solve the problem of poor excitation conditions and quickly select the best surface obstacle replacement excitation point. In addition, with the development of the new "two wides and one high" efficient seismic acquisition construction technology, construction is developing towards high efficiency and scale. A large number of surface obstacles need to be effectively confirmed before construction. The complex obstacle area formed by various underground and surface facilities has a great influence on the layout of precise shot detection points. It is necessary to conduct detailed pre-design of the excitation points, and to verify whether the excitation factors and matching drilling types are in line with the actual field conditions. A large amount of field production data needs to be sorted and summarized every day to control the construction progress and quality, verify the workload and production progress, and provide timely feedback on field construction to improve construction quality and quality control efficiency.

[0003] Hu Changqing and others published "Application of Precision Pre-design Technology in Complex Obstacle Areas in Central Sichuan" in the proceedings of the 2021 Geophysical Prospecting Technology Seminar of the China Petroleum Society, and Su Chang published "Research on Methods to Improve the Success Rate of Pre-design of Complex Surface Physical Points" in "Science and Technology", Volume 29, Issue 5, 2021. They conducted technical research on the design of excitation points, using high-definition satellite images as the image source and precise vectorized extraction data as the basis. The gun and detection points were then offset according to terrain parameter factors. Finally, on this basis, the points in the complex obstacle area were pre-deployed, basically realizing the precise pre-design of excitation points in complex obstacle areas.

[0004] In the process of seismic acquisition in complex exploration areas, the design of the excitation points must not only optimize the surface conditions for excitation, but also maintain the uniformity of the excitation points in space; timely grasping and verifying the progress and quality of seismic acquisition construction is the biggest difficulty; the Chinese invention patent with application publication number CN111274337A provides a two- and three-dimensional integrated GIS system based on real-life three-dimensional. From the perspective of combining the bottom layer of data, two-dimensional and three-dimensional map data, the fusion of the spatial analysis capability of the two-dimensional geographic information system and the display capability of the three-dimensional geographic information system is studied, and the fusion of the spatial analysis capability of the two-dimensional geographic information system and the display capability of the three-dimensional geographic information system, and the two- and three-dimensional integrated linkage of the map data of the GIS framework are realized to improve the accuracy of the location and reduce the deviation of the information location. However, the GIS system usually only meets the linkage and integration between the three-dimensional geographic information system and the three-dimensional graphics system, and cannot exchange and link with external information in a timely manner; and the existing geophysical acquisition design software or acquisition information software used to obtain seismic acquisition information has a slow response speed, which is difficult to meet the requirements of seismic exploration field acquisition site design, quality control and field production real-time information clearly displayed in two-dimensional and three-dimensional map scenes. Therefore, it cannot adapt to the real-time linkage with seismic production information, resulting in difficulty in timely and intuitively grasping and verifying the progress and quality of seismic acquisition construction. Summary of the invention

[0005] The purpose of the present invention is to provide a method for linking a GIS platform with seismic acquisition information, an excitation point design method and system, so as to solve the problem that it is difficult to timely exchange and link information between the existing GIS system and the seismic acquisition construction, resulting in difficulty in timely and intuitively grasping and verifying the progress and quality of seismic acquisition construction.

In this embodiment, 0-30 degrees (the first set slope threshold range) is a gentle slope, and 30-90 degrees (the second set slope threshold range) is a steep slope; according to the bedrock and loess thickness survey data corresponding to the target area, different types of sub-areas are zoned and mapped according to lithology and loess thickness to obtain a near-surface stereo model. After obtaining the near-surface stereo model, the surface obstacles are determined according to the obtained near-surface stereo model, and the obstacle safety construction boundary is delineated, such as Figure 3a This is a schematic diagram of surface obstacles determined based on the 2D near-surface stereo model.

The effect of the pre-design of the excitation points in the target area of ​​this embodiment is as follows: Figure 6 As shown, Figure 6 The marked points (white origins) in the figure are the pre-designed excitation point positions. Figure 6 The pattern in the lower left corner is the operating symbol of the operation interface; after the preliminary design of the excitation point is completed, the design task book is issued through the real-time seismic information acquisition system, and the results of the field on-site stakeout excitation points are measured; through the linkage of real-time seismic acquisition information data and GIS software, it can be matched with the design task book in a timely manner, verify the real-time field workload and work progress, and adjust the drilling type matching and other issues in a timely manner.
