Research and Application of a New Type of Water Flooding Characteristic Curve in Oilfield Development

Zhibin ZHOU, Jiexiang WANG

Abstract


During the exploitation process of an oilfield, the traditional water flooding characteristic curve is not suitable for high water cut period. It often appears “downwarping” phenomenon in high water cut stage, so the prediction accuracy of water drive development becomes bad. Therefore, the paper has presented a new type of water flooding characteristic curve, which has good adaptability in high water cut stage. Based on the characteristics of oil-water relative permeability and water saturation curve, the new type of water flooding characteristic curve put forward a new method to characterize the flow characteristics, considered the limit of water drive development, and gave a simple method of parameter calculation. The new water flooding characteristic curve can reflect the high water cut reservoir seepage characteristics. The traditional water flooding characteristic curve is a special case of the new water flooding characteristic curve when the recovery percent of reserves is low. The new water flooding characteristic curve can be used to carry out the actual field application. The results showed that the prediction accuracy of the new water flooding characteristic curve was increased by 5.42%, compared with the traditional water flooding characteristic curve. The new water flooding characteristic curve has better adaptability than the traditional water flooding characteristic curve in high water cut stage.
