Description

Three-dimensional geological model modeling method and device and readable storage medium
Technical Field
The invention relates to the technical field of geological modeling, in particular to a three-dimensional geological model modeling method, a three-dimensional geological model modeling device and a readable storage medium.
Background
Three-dimensional geological modeling is always a technical hotspot and difficult problem for research in engineering, geology and mineral industry. The geological structure shape and the rock physical property parameters under the limited geological data recovery site play a very important role in engineering geological analysis, oil gas and mineral exploration and development. Due to the diversity and the multi-solution of geological data and the limitation of data acquisition means, the three-dimensional geological modeling has high difficulty and complex realization process. Three-dimensional geological modeling by encoding a formation is a common approach. The three-dimensional geological model constructed in the way can relatively accurately reflect complex geological phenomena in the stratum, such as an interlayer, a boulder and the like, thereby providing basic data support for underground space utilization evaluation.
However, in the prior art, there are three methods for encoding the formation: (1) adjacent borehole formations are connected. According to the standard stratum sequence, if the inversion does not occur, the stratum of the drill hole is traversed in sequence from top to bottom, and the same stratum of adjacent drill holes are directly connected. If the adjacent borehole has missing formations, then the direct 1/2 pinches out. (2) And (3) carrying out stratum extension treatment on the ultra-shallow borehole. And (4) giving an extension depth according to the stratum of the peripheral drilling hole and the standard sequence, and interpolating the buried depth of the bottom plate of the extended stratum. The formation connection is carried out according to the method (1). (3) Determining and coding the stratum sequence of the interlayer. If the stratum of the drilled hole contains the interlayer, the stratum sequence of the drilled hole cannot meet the requirement of the standard sequence, and the stratum connection cannot be directly carried out. The method mainly comprises the steps of firstly finding out a stratum code S where an interlayer in a drill hole is located, respectively marking an upper S layer and a lower S layer of the interlayer as S1 and S2, then splitting the stratum S in the peripheral drill hole into S1 and S2, firstly realizing the connection of S1 and S2, and then connecting the interlayer through a pinch-out technology. And finally, taking out the common surface between the S1 and the S2.
However, the three methods for coding the stratum cannot deal with the situation that the stratum is inverted, so that the problem of stratum connection multi-solution caused by inversion of the stratum occurs, and the technical problem that the reliability of the constructed three-dimensional geological model is not high is caused.
