Conventional well testing analysis refers to a series of analytical well testing methods based on unstable seepage put forward by foreign scholars in the early 1980s, which mainly use pressure and derivative well testing analysis methods. The software can complete the pressure drop and pressure recovery well testing analysis of oil producing wells, injection wells and gas production wells, and use multi-flow superposition to calculate typical curve chart for pressure and derivative curve simulation.

The software provides a variety of simulation methods, such as mouse simulation method, rolling bar simulation method, nonlinear regression simulation method, keyboard input simulation method and so on, which improves the well testing interpretation speed and simulation accuracy, and develops several modules, such as typical curve library, unit system transformation and so on.

The main models of the software are as follows:

Flow types: Darcy flow, non-Darcy flow and fractal reservoir, etc.

Seepage model: Homogeneous formation, pseudo-steady double pores, unstable double pores, double permeability and so on.

Geological model: Single medium, radial composite, linear composite and multi-layer oil and gas reservoir, etc.

Wellbore conditions: 12 types of wellbore, such as full/partial perforation oil well, vertical fracture, horizontal fracture, horizontal well and inclined well.

Wellbore types: Constant well reserve, Fair variable well reserve, Hegmen variable well reserve and USTC variable well reserve.

Reservoir boundary: 8 types of combination method such as infinite boundary, river boundary, angle oil and gas reservoir and so on.

Fluid types: Oil, water, known gas components and unknown gas components, etc.

Considering the combination of the gas cap, bottom water, outer boundary closure and constant pressure, the partial differential equation will reach more than 90000 kinds of solutions.
