According to the production of dense oil/gas and shale gas, horizontal well multistage fracturing has been used widely, based on the decrease of shut in pressure recovery data of well testing analysis, and long-time monitored pressure and flowrate on the surface are essential for each oil-gas well, to interpret and analysis formation parameters, a dynamic method that can analysis the change of flowrate/pressure must be applied. So we developed our production data analysis software.

The data analysis function of oil and gas well under variable  flowrate and pressure can be realized, through the analysis, the parameters such as formation permeability and reserves can be obtained, and these parameters can be used to predict the productivity of oil and gas wells in the future.

The traditional production data analysis method is provided, and the combination analysis method is developed according to the theory of seepage mechanics.

Bottom hole pressure conversion function, wellhead flowrate and pressure data analysis are provided.

Flowrate and pressure prediction by analysis parameters.

The traditional production data analysis is provided, including Arps method of flow decline, Fok combination analysis method; and according to the pressure deviation theory, the data analysis of pressure difference per unit flow is provided. The geological model is comprehensive, and the application range of production data analysis is  extended.

The method for predicting the bottom hole pressure and the flowrate under the material balance time is provided, and the pressure and the flow rate change are predicted. Our software runs fast and accurate.

According to the principle of production data analysis, each functional module is developed into components by using object-oriented technology of VC++, and the components are integrated into production data analysis software, which can be widely used in the optimization of working system and development scheme in oil and gas well exploration and development, especially for the analysis of bottom hole pressure data which can not be measured in dense oil and gas development, and the formation pressure distribution is given for the first time from the point of view of analytical solution, the average pressure at different time can be calculated from the pressure distribution, and many calculation methods from foreign production data analysis software are improved, which makes the production data analysis software more in line with the actual demand.
