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.
