Well testing analysis is the key technology to obtain the dynamic parameters of multi-stage fracturing horizontal wells, through which the productivity of multi-stage fracturing can be calculated and optimized. The software uses analytical and numerical solutions to optimize multi-fractures in horizontal wells.

The software includes low permeability reservoir modeling technology, which can solve the interpretation and analysis of bottom hole pressure data of low permeability reservoir and the productivity evaluation of horizontal well multi-fracture in different time, and finally form the calculation program of horizontal well multi-stage fracturing productivity evaluation with stable convergence algorithm by using analytical and numerical solution technology. Considering that the productivity evaluation of multi-stage fracturing in horizontal wells needs to establish the relationship between bottom hole flowing pressure and surface production at different time, GPU is used to calculate and improve the calculation speed.

Main technology:

Low-permeability well testing and full-history simulation of production new technology: Providing low-permeability test (such as DST and swabbing test), full-history simulation and simulation new technology, and solving the problem of low utilization rate of the data of the exploration well.

The new technology of multi-fracture productivity prediction of horizontal well is formed: The formation seepage equation considering the heterogeneity is established, and the solution of the heterogeneous seepage equation of the multi-fracture of the horizontal well is researched.

Forming a numerical simulation calculation method for a non-structural PEBI grid production, and providing a calculation tool for the horizontal well multi-fracture production forecast.

A unified communication protocol and data interface are developed based on the software architecture design of the component, so that the component can be easily reused.
