Problems solved by technology

[0003] Therefore, it is extremely important to deduce the position of the unknown sub-layer fault based on the known structural interpretation of the fault horizon. At present, in the geological research industry of oilfield development, the faults of the target sub-layer (intermediate sub-layer) are drawn by manual comparison of the upper and lower layer faults, which is not only time-consuming, but also and not precise enough

Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing by non-limiting embodiment:

[0017] Such as figure 1 As shown, the embodiment of the present invention provides a method for drawing small and medium layer faults in oil reservoirs, and the specific steps are as follows:

[0018] Step 1: Digitization of known plane fault lines;

[0019] Step 2: Number the known digital fault lines, and mark the types of fault lines on the upper and lower walls of the fault, so as to facilitate the batch processing of program design;

[0020] Step 3: Calculating the stratigraphic horizon space data among known upper faults, lower faults and unknown faults;

[0021] Step 4: Deriving unknown fault data, deriving unknown fault data in batches through software programming. The derived digitized faults can be used in other software.

[0022] Step 1 may be: the construction interpreter constructs the interpretation horizon fault line through the...

Abstract

The invention provides a method for drawing faults in middle and small layers of oil layers and belongs to the technical field of petroleum exploration. The method comprises the following specific steps: 1, digitizing known planar fault lines; 2, numbering the known digitized fault lines and labeling types of the fault lines of upper and lower sides of faults; 3, calculating the known stratigraphic position spatial data among upper faults, lower faults and unknown faults; and 4, deriving the unknown fault data in batches through software programming. The method disclosed by the invention has the advantages that the faults of target small layers (middle small layers) are effectively drawn; and the efficiency and the derivation precision of the fault drawing are increased.

Description

technical field [0001] The invention relates to a method for drawing faults in medium and small layers of oil layers, and belongs to the technical field of petroleum exploration. Background technique [0002] In the process of comprehensive research on development geology and fine reservoir description, there are relatively high requirements for the production of small-layer sand body top surface structural maps (or micro-structural maps), which is also a situational requirement for deep tapping of oilfield potential. This requires the vast number of geological researchers to draw corresponding geological maps related to sub-layers in actual work with the sub-layer structure map as the base map. Faults are the basic map elements of sublayer structural maps. In practice, it is impossible for structural interpretation to provide structural maps of each sub-layer and sub-layer-based planar fault lines through the standard layer tracking technology of corresponding structural i...
