Embodiment Construction
[0036] In order to better understand the purpose, structure and function of the present invention, a method for generating three-dimensional scattered points of underground reservoir microstructure according to the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0037] like Figure 1 to Figure 7 As shown, the generation method of the three-dimensional scatter point of the underground reservoir microstructure of the present invention comprises the following steps:
[0038] Step 1: Dismantling the seismic data into two parts: track head data and data body. Disassemble the track head and data body separately, use the track head data to determine the spatial distribution position and data interval of the data body, and use the data body to obtain The change characteristics of seismic amplitude data, based on the plane coordinate data in the trace head data, assign the plane coordinate position to each data track in the d...

The invention provides a method for generating three-dimensional scatter points of an underground reservoir micro-structure. The method comprises the following steps of: 1, disassembling seismic data into seismic data points with space coordinates; 2, delineating seismic traces in a research range according to the plane position of an underground reservoir; 3, determining a search start point and a search end point on each seismic trace according to the depth range of research; 4, calculating the depth of data points, meeting the reservoir seismic characteristics, on each seismic trace; 5, eliminating data points with abnormal construction depth values; and 6, outputting three-dimensional scatter point data of a reservoir micro-structure, and completing generation of three-dimensional scatter points of an underground reservoir micro-structure. The method can improve the speed and precision of micro-structure identification, and is of great significance to research of underground reservoir structures.
Description
technical field [0001] The invention belongs to the technical field of underground reservoir microstructure research and three-dimensional geological modeling, and in particular relates to a method for generating three-dimensional scattered points of underground reservoir microstructure. Background technique [0002] In the process of geological research, the spatial distribution of underground reservoir structures is obtained through seismic sections combined with geological stratification. This work plays an important role in understanding the structure of underground reservoirs, and is an important task for geologists and geophysical personnel. When the structure identification of the top surface of the reservoir reaches the reading of seismic traces one by one, the obtained microstructure information can reflect the change details of the reservoir structure in a more precise manner, which can effectively improve the geological personnel's understanding of the reservoir st...
