LINEAR PROCESSING METHOD IN MATERIAL BALANCE

Oil (gas) reservoir has a characteristic of complex geologic structure. In initial production stage, the application of some reservoir engineering methods is confined for insufficient information. The material balance method need not take complex underground seepage characteristics into account, only need fewer geologic information, fluid physical testing data and some production performance information, and its calculation method and program is simple. So, this paper had built the material balance equation suited for various type of reservoir and carried out linear regression, the calculation result could determine reservoir reserves and oil well productivity veraciously, and carry out dynamic analysis and prediction to reservoir.
