Analysis and Calculation Method for Automatic Water Flooding Technology

Bounded thin oil reservoir, which is characterized by less reserves, thin thickness, and weak energy of edge or bottom water, could hardly be developed with high cost, low recovery and high risk. Bajiaoting oil field has all the characteristics of bounded thin oil reservoir, whats more, it has low permeability. As a result, it could not be developed without water injection wells, but water injection cases could not be taken in Offshore Oil Fields due to the restrictions of the producing platform. Face all the difficulties, Water Flooding, which could maintain pressure and improve recovery with low cost, was, and it is the first time that this technology applied in China offshore. In this study, related calculation methods for pressure and injection rate are applied, and the effects and simulation results of some adjustment cases are discussed.
