Productivity evaluation is one of the important tools for oil and gas field exploration and development. The software is developed according to the characteristics of oil and gas field exploration and development, the software can carry out pressure drop, pressure recovery and edge test well testing design for self-flowing wells and non-self-flowing wells, especially for the non-self-flowing well, well testing design function is first time realized in China. The software takes into account of oil, gas, water and other fluids, formation seepage and various types of wellbore, and meanwhile provides various types of boundaries: The outer boundary can be the random combination of closed and constant pressure. Gas cap and bottom water are considered for partial perforation, horizontal fracture, partial pressure opening and horizontal well.
