The software adopts a non-structure PEBI grid, and can perform
precise grid division on different well types such as vertical well, vertical fracture well,
horizontal well and horizontal well multi-fracture, fully considers complex well type, fault
and boundary interference, not only provides pressure history simulation, the well testing
analysis of multi-well bottom hole pressure recovery data in different periods is also
carried out.
Numerical simulation of the shale gas well: Considering the
adsorption of the shale gas, the gas slip and the formation pressure-sensitive effect, and
considering the starting pressure gradient and so on.
Using three-phase and five-component equations, the numerical
simulation research of polymer flooding and polymer surface flooding can be carried out, and
various physical and chemical phenomena can be considered, and the distribution of polymer
concentration can be obtained.
According to the calculation and analysis of large volume
fracturing in the development of dense oil and gas, the back flow data after pressure and
the production data can be simulated, we obtain the volume of the SRV, the effective length
of the crack and the distribution of permeability and so on, and the future productivity of
the oil and gas well is predicted.
Provide multi-stage pressure optimization of horizontal well: The
multi-fracture of horizontal well is numerical simulated, the optimization of the fracturing
scale (crack length, number of cracks, etc.) is realized, and the productivity of the oil
gas well is predicted.
