Problems solved by technology

[0006] However, the query speed of conventional database indexes is very slow. The search speed of a 30G data body is usually more than 1 second, and the index file itself needs to occupy about 1 G of space, which leads to the 3D seismic data volume of a certain acquisition plane at the server end. The graphics speed is slow, which in turn reduces the transmission speed of the 3D visualization image to the client and affects the user experience

Embodiment Construction

[0065] The present invention is described in detail below in conjunction with accompanying drawing:

[0066] Such as figure 1 As shown, the present invention provides a method for rapid network visualization of 3D seismic data, comprising the following steps:

[0067] S1, the storage unit of the server stores all 3D seismic data volumes in the research area;

[0068] S2. The server creates a bitmap index of all the 3D seismic data volumes;

[0069] S3. When a request message for displaying an image of a specified local area in the research area is received from the client, wherein the request message carries coordinate values ​​of plane feature points of the specified local area;

[0070] The server searches the storage unit through the bitmap index to obtain a specific 3D seismic data volume corresponding to the coordinate value of the plane feature point, and then locates in the complete picture based on the specific 3D seismic data volume to obtain the designated local a...

Abstract

The invention provides a rapid network visualization method of three-dimensional seismic data. The method comprises the following steps that a memory cell of a server stores all three-dimensional seismic data cubes in the study area; the server establishes a bitmap index of all three-dimensional seismic data cubes; when the request message for displaying a specified local area image in the study area transmitted by a client is received, the server searches the memory cell through the bitmap index, acquires the special three-dimensional seismic data cube corresponding to the plane feature point coordinate values, positions in a complete picture based on the special three-dimensional seismic data cube and acquires the specified local area images; the server compresses the specified local area images to obtain compressed local images; the server transmits the compressed local images to the client through network; and the client displays the compressed local images. By improvements from various aspects, the display speed of three-dimensional visualization images at the client is enhanced, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploration, and in particular relates to a fast network visualization method for three-dimensional seismic data. Background technique [0002] 3D seismic exploration has become the main technology of oil and gas exploration and development today. A large number of 3D seismic data volumes are collected through 3D seismic exploration technology, and then the 3D seismic data volumes are stored in a storage device. At present, the visualization method of 3D seismic data is usually used to facilitate people to carry out geological modeling and geological research on 3D seismic data. [0003] 3D seismic data network visualization refers to: the server side stores a large number of 3D seismic data bodies; when a client needs to read the seismic data visualization image of a certain research area, the server side searches for the storage device and reads the required 3D seismic data. Seismic data vol...
