Then pusher accesses drilling well real-time parameter interface, is often connected to the real-time parameter at one group (i.e. a certain moment), then select and current
The shaft structure and drill assembly data that well depth matches, grouping are pushed to three-dimensional scenic, reach facing for " looking at underground well-digging "
Border effect so that technical specialist and production manager can remotely monitoring site be constructed in environment true to nature, is made in time certainly
Plan improves construction efficiency, avoids the generation of accident.
In oil exploration, drilling well takes up to 50-70%, especially bores labyrinth under complex geological condition
Well, ultradeep well, mega-extended-reach well and special well and when exceeding the maximum, there is a large amount of anisotropism, uncertainty, non-knots
The problem of structure, nonumericization solves the problems, such as that there is an urgent need to information technology, intellectual technology and the present age are high-end for these engineering "black box"s
Science and technology realizes the vision of " looking at underground well-digging " that industry is expected.In order to reduce to the greatest extent accident, improve drilling efficiency and at
Power, on computers emulation well-digging become the technological trend that industry is generally accepted, will be widely used.Computer virtual is imitative
True system structure is complicated, and the data class of input is more, real-time, needs pit shaft, drilling tool, drilling in the same three-dimensional scenic
State, underground risk, which synchronize, carries out display true to nature, which is advantageously implemented between input data and three-dimensional scenic rendering function
Loose coupling, it is ensured that the efficiency and robustness of system.
Above-mentioned technical proposal is one embodiment of the present invention, for those skilled in the art, at this
On the basis of disclosure of the invention application process and principle, it is easy to make various types of improvement or deformation, be not limited solely to this
Invent method described in above-mentioned specific implementation mode, therefore previously described mode is only preferred, and and without limitation
The meaning of property.
