A new method for calculating the production pressure difference of far wells in fractured-vuggy carbonate reservoirs

The Tahe oil field is a typical fractured-vuggy carbonate reservoir. The quantification of the pressure difference in far well reserves has been a difficult problem. Based on field practice, a method for calculating the production pressure difference needed for the production of far-well reservoir was deduced by using water injection curve. It was proved reliable by field application, and could be used to guide production.
