Abstract

The invention provides a full three-dimensional linkage earthquake explaining method of a complicated geologic structure comprising a reverse fault, which comprises the following steps: establishing a horizon and a fault, and obtaining a horizon point and fault data; carrying out linkage and explanation on the horizon point according to a structure without the reverse fault to obtain horizon point explaining data on section planes; explaining the fault data according to section plane information to obtain fault explaining data on the section planes; carrying out fault combination on each section plane based on the horizon point explaining data and the fault explaining data to obtain fault explaining data in a spatial mesh form; re-explaining the repeated part of the horizon of the structure comprising the reverse fault according to the fault explaining data in the spatial mesh form, so as to obtain the horizon point explaining data comprising the reverse fault on the section planes; subjecting the fault explaining data in the spatial mesh form to interpolation to form a three-dimensional fault plane; and subjecting the horizon point explaining data on the section planes to the interpolation to form a three-dimensional horizon plane according to the three-dimensional fault plane.

Description

technical field

[0001] The invention relates to a seismic interpretation method, more specifically, the invention relates to a full three-dimensional linkage seismic interpretation method for complex geological structures containing reverse faults. Background technique

[0002] 3D seismic interpretation technology is developed on the basis of 2D seismic interpretation technology. Compared with 2D seismic interpretation, 3D seismic interpretation can perform seismic structure interpretation more intuitively and accurately. Developed countries began to use 3D seismic technology in the 1970s. my country's 3D seismic technology developed rapidly in the 1980s, and now it has formed a complete technical system including field data acquisition, indoor data processing and result interpretation, which has played an important role in oil and gas exploration and development. 3D seismic is a seismic area exploration method in which the seismic surveying network is arranged in a grid or...
