Abstract:

Material balance equation(MBE)is one of the basic tools to explain and forecast the reservoir dynamics. It is
truly an actual problem that reservoir engineers need to be faced. Prevalent commercial software are commonly to be used to
solve the MBE currently,but which cost too much rather than the traditional methods,however,it always need to be linearized
first and usually to apply manually an adopting cut-and-try method,so it′s efficiency is comparatively low. When knowing
a little reservoir pressure and production data,taking reservoir basic parameters as decision variables and describing MBE as
a nonlinear programming and utilizing the function of solving multi-variety′s programming problems provided programming
module could automatically get a accurate basic parameters and average pressure and the water influx behavior of aquifer.
Comparison with the calculation result of formers,it is reliable and have highly operability.

Key words: reservoir engineering, material balance, nonlinear programming, water influx, programming solver
