It is understood that a specific example of the base map is shown in fig. 3, wherein a08, a13, and a16 are each identifications of different wells within a work area, and their locations also represent corresponding logging locations.

Step 200: acquiring seismic channel data corresponding to at least one pre-stored seismic channel and geological data of a target layer within a preset range taking the target position as a center, and acquiring logging data of the target layer corresponding to the logging position if the logging position exists within the preset range taking the target position as the center through searching, wherein the target layer and the acquisition range of the logging data are preset.

In step 200, if the well-seismic data combined display device receives an information query instruction for the base map, the seismic trace data corresponding to at least one pre-stored seismic trace within a preset range centered on the target position and the geological data of the target layer, it can be understood that the preset range centered on the target position may be preset according to an actual application situation, for example, the preset range centered on the target position is a circular range centered on the target position and having an actual radius of 5 meters.

It can be understood that, because the different wells in the same work area are distributed relatively far, the logging position is not necessarily found within the preset range centered on the target position, and therefore if the logging position is found within the preset range centered on the target position, the logging data of the target layer corresponding to the logging position is obtained, and if the logging position is not found, the seismic channel data corresponding to the seismic channel and the geological data of the target layer are directly displayed in the suspension frame.

It is to be understood that the shape and size of the suspension frame may be preset by setting information input by a user, for example, the size of the suspension frame may be set to a rectangular frame capable of adapting to the display data amount of the seismic trace data corresponding to the seismic trace, the geological data of the target zone, and the logging data of the target zone corresponding to the logging position.

In order to acquire and store the seismic trace data and the corresponding index in advance, so as to further improve the efficiency and reliability of the joint acquisition and display of the well-seismic data, in an embodiment of the present application, before step a00 in the well-seismic data joint display method of the present application, step B01 and step B02 are further included, referring to fig. 5, where step B01 and step B02 specifically include the following contents:

Step B02: and storing the seismic channel data corresponding to the line channel number of each seismic channel in the depth domain seismic data into an index file, wherein the seismic channel data comprise the position coordinates of the seismic channel and the offset position of the seismic channel.

Specifically, the well seismic data combined display device acquires the depth domain seismic data in the SEG-Y format, extracts the coordinates and line channel numbers of each channel, and stores the coordinates and line channel numbers together with the offset position in the file of the seismic channel in the index file. The index file is used for quickly searching the seismic channel with a specific line channel number.

It is understood that the SEG-Y format is one of the standard tape data formats proposed by SEG (society of explicit geopathics), and a standard SEG-Y file generally includes three parts, the first part being an EBCDIC header (3200 bytes) composed of 40 cards (for example, 80 characters per line by 40 lines) for storing some information describing the seismic data volume; the second part is a binary file header (400 bytes) used for storing some key information describing the SEG-Y file, including some information such as the data format, the sampling point number, the sampling interval, the measurement unit and the like of the SEG-Y file, and the information is generally stored at a fixed position of the binary file header; the third part is the actual seismic traces, each containing 240 bytes of trace header information and seismic trace data.

The common file header area records the common information of the LAS file, such as the number of points and the like; the variable length recording area comprises metadata such as a coordinate system adopted by a file; the format point set recording area is used to record X, Y, Z and attributes of the points. The three modules are closely connected and interrelated.

Specifically, the well-seismic data combined display device counts the work area coordinate range of the seismic channels, and displays the work area distribution position and the well position on a work area base map by using a specific scaling according to the range.

In order to further improve the intelligence and convenience of the joint acquisition and display of well-seismic data, in an embodiment of the present application, step 300 of the joint display method of well-seismic data further includes

Each record storage content of the index file comprises a line number, a track number, east-west coordinates, north-south coordinates and an offset position of corresponding seismic track data in an SEG-Y file. The index file provides the functions of quickly searching specific seismic channels according to the coordinates and reading seismic data.
