Problems solved by technology

Therefore, the usual method of random simulation - to establish an ordinary formation, and then generate a virtual oil layer by generating random heights and random colors, although the basic simulation of the virtual oil layer can be realized, but the display of the oil blocks in the oil layer is relatively messy, and the effect is not good. Ideal, the simulation and true reproduction of the oil layer cannot be realized

Embodiment Construction

[0037] figure 1 It is a flowchart of the two-dimensional Diamond-Square algorithm in the present invention. The two-dimensional Diamond-Square algorithm stipulates that the number of two-dimensional arrays is equal in length and width and is 2 N+1 +1 (eg 33*33). First initialize (11): set the initial height values ​​at the four corners, set the random height range (h, H) and the smoothing coefficient W, take the value (0.0, 1.0), and set the random number factor factor=1 (12); Second, the recursive subdivision process:

[0038] 1.diamond step (13): Take a square with four points, and generate a random value at the midpoint of the square (the intersection point of two diagonal lines). The midpoint value is calculated by adding the average value of the four corner points plus the random quantity rand(h, H)×factor. Where rand(h, H) represents a random number in the range (h, H).

[0039] 2. Square step (14): Take the pyramid formed by each four points, generate a random valu...

Abstract

The method includes three parameters for initializing oil layer L: random range of height, smoothing coefficient W, and coefficient of oil content R; building a minimal height field M represented in exponent of 2 with its long and width being larger than oil layer L, and using modified Diamond-Square algorithm to generate value of height; assigning the value of height to virtual oil layer L, and discarding height field not belonging to height field of oil layer; creating irregular effect of oil layer, and traversing virtual oil layer L, and calculating random color value for each point. Thus, the invention can draw virtual oil layer accorded with natural distribution on display screen so as to simulate underground oil layer factually and rapidly.

Description

technical field [0001] The invention relates to a system and method for natural simulation of a virtual oil layer. Background technique [0002] The development of a virtual reality system for the oil field environment can improve the digitalization of the oil field, free the design and construction developers from low-level drawing and construction, and facilitate a series of production processes such as oil exploration, design, and drilling development, thereby accelerating the speed of oil development and production. [0003] The oil field environment includes three-dimensional information such as underground formations, oil areas, drilling targets, and drilling trajectories, among which the distribution of underground oil areas is the most important link. As we all know, because the oil is buried underground, the specific distribution and pressure of the oil area are difficult to be detected or identified, so the simulation of the virtual oil layer cannot use the known r...
