Embodiment Construction

[0016] The present invention is described below with reference to exemplary embodiments of the invention and the accompanying drawings.

[0017] Before introducing the horizon interpolation method for 3D seismic interpretation of complex geological structures with reverse faults proposed by the present invention, first introduce the physical meanings of several data in this method:

[0018] Point: Each data point in the interpreted data describes the time or depth of a horizon or fault along the trace. Since the seismic data is also recorded in the way of sampling at equal intervals in practice or depth, the position of the data interpretation point on the track can be simply described by the sampling point position of the seismic data.

[0019] Segment: Explain that the concept of a data segment refers to consecutive data points that do not overlap on a trace. The introduction of segments is mainly due to two factors. The first is that segments can accurately describe the ho...

Abstract

The invention provides a method for carrying out horizon interpolation on three-dimensional seismic interpretation under the condition of a reverse-fault containing complex geological structure, which comprises the following steps: carrying out interpolation on horizon points which are not leaped by a reverse fault; carrying out interpolation on horizon points which are leaped by the reverse fault; assembling the horizon points subjected to interpolation into horizon sections in xline and inline directions, and then forming a horizon surface; and after implementing the action of horizon section assembling, storing horizon data into a work region in a file form.

Description

technical field [0001] The invention belongs to the field of seismic interpretation, and more specifically relates to a method for horizon interpolation in three-dimensional seismic interpretation of complex geological structures containing reverse faults. Background technique [0002] 3D seismic technology is developed on the basis of 2D seismic technology. 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. Three-dimensional seismic is a seismic area exploration method that arranges the seismic survey network in a grid or ring according to certain rules. It can greatly improve the underground common depth point (refers to the midpoint of the line connecting the shot point and the...
