Through the perfection and improvement of the numerical well test software, Chengong numerical well testing software has been developed into block fine simulation software, which is between the traditional well testing software and reservoir numerical simulation software. The software can accurately simulate the bottom-hole flowing pressure, pressure  distribution and saturation distribution of dozens of wells in a period of 1-5 years, can greatly improve the precision of the dynamic prediction of the oil reservoir, and can carry out the fracturing optimization scheme design, and compare and calculate multiple horizontal well fracturing schemes.

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.
