Problems solved by technology

For the mapping of each sand body, the application of current mapping software requires data acquisition, manual drawing of sand body boundaries, gridding of mapping data, generation of contour lines, selection of well locations and adjustment of their size according to the mapping range, Steps such as manual generation of graph borders are carried out step by step, and the workload is huge
At present, there are few researches on automatic mapping at home and abroad, and a set of fast mapping methods has not yet been formed.

Embodiment Construction

[0021] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.

[0022] like figure 1 as shown, figure 1 It is a flow chart of the method for automatic and rapid sand body mapping of the present invention.

[0023] In step 101, the data to be mapped is input, and the format of the data is abscissa, ordinate and attribute value of mapping, ie (x, y, z). The process goes to step 102.

[0024] In step 102, the graphed data is gridded. Gridding is the process of obtaining raster data through spatial interpolation of discrete known data. Mapping data is usually sparse and limited, and the gridded data obtained through interpolation can spatially display the underground situation. The quality of the gridding method not only directly affects the quality, accuracy and credibility of the gridded data, but also furt...

Abstract

The invention provides an automatic rapid mapping method for a sand body. The automatic rapid mapping method includes step 1, meshing mapping data; step 2, tracking contour lines automatically; step 3, generating boundaries automatically; step 4, adding well positions automatically; step 5, generating a mapping frame automatically. The automatic rapid mapping method has the advantages that a set of methods including data meshing, contour line tracking, sand body boundary generation, well position addition, automatic frame generation of the geographic position of the sand body and the like is developed according to mapping customs and quality requirements of sand body structural maps, thickness maps and the like and is integrated to form a rapid mapping process, so that mapping time of geological researchers is saved greatly, and exploration deployment quality and benefit are improved.

Description

technical field [0001] The invention relates to sand body mapping, in particular to an automatic and rapid sand body mapping method. Background technique [0002] The traditional mapping method is mainly manual. The current exploration objects are gradually turning to lithological traps. Channel sand and turbidite bodies have become the main targets of exploration. The overall exploration deployment of the zone requires multi-layer, multi-type, and large-scale Comprehensive description and prediction of small sandbodies within. For the mapping of each sand body, the application of current mapping software requires data acquisition, manual drawing of sand body boundaries, gridding of mapping data, generation of contour lines, selection of well locations and adjustment of their size according to the mapping range, The steps of manually generating the frame of the map are carried out step by step, and the workload is very huge. At present, there are few researches on automa...
