Problems solved by technology
[0005] 2. Multiple overthrust fault blocks are complex: the difficulty of interpreting multiple overthrust faults increases, and if a relatively simple interpretation operation process cannot be presented, the difficulty of fault block analysis will increase
[0012] 3. After the interpretation is completed, the layers and faults need to be divided into blocks for combination or edited into maps, which reduces the efficiency of map-making

Embodiment Construction
[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0033] The present invention proposes a storage method for reverse fault interpretation results. The methods for reverse fault interpretation and normal fault interpretation should be the same. This method does not complicate the interpretation operation process because of the overlap of reverse fault layers. Potential energy overlaps each other, and overlapping data is recorded, and the upper and lower walls of the fault are interpreted at one time. No matter how complicated the fault is, how many overlapping fault blocks there a...

The invention provides an explanation result storage method for a reverse fault. Based on the storage method, the one-time direct explanation of the reverse fault can be completed. The method comprises the steps of obtaining the cross-sectional view of a reverse fault; changing the storage mode of an explanation result to be a linear mode, directly interpreting a reverse-evolvement repeated position in the section by adopting a positive fault explanation method, and storing interpreted result data in a linear data mode. The storage content comprises X, Y, Z, position, line name and ID, whereinthe ID is the serial number of a continuous explanation result line. The linear data storage mode is used for storing a plurality of explanation data of different ID numbers in the same level and atthe position of the same common-depth point (cdp). After the explanation is completed, a position repeated explanation result is subjected to one-time gridding formation. According to the invention, the explanation process is more visual, and the explanation accuracy is improved. The complexity degree of fault explanation is reduced, and the image forming efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of geological analysis, in particular to a method for storing reverse fault interpretation results, which can complete one-time direct interpretation. Background technique [0002] A fault is a rupture of the underground rock layer when the force reaches a certain strength, and there is obvious relative movement along the rupture surface. It plays an important role in controlling the migration and accumulation of oil and gas. Therefore, the interpretation of faults is an important content of seismic interpretation. In actual comparison, different types of faults are formed due to changes in the formations near the faults. A type of fault, which is a fault in which the hanging wall rises and the footwall falls relatively, and is mainly formed by horizontal extrusion. According to the dip angle of the section, it can be further divided into: high-angle reverse faults, also known as thrust faults (section dip ...
