Abstract

In the conditions of pressure maintenance when balanced injection and production rate, produced gas-oil ratio should remain stationary. Conversely, take Sabei oilfield as an example, along with the development entered high water cut period, the value of its produced gas-oil ratio increased significantly. In view of this abnormal phenomenon, firstly, we analyze the impacting factors of the produced gas/oil ratio theoretically. It include well spacing density, bottom hole flowing pressure and saturation pressure. In terms of those impacting factors, we carry out the study through numerical simulation. As the results indicated, the produced gas/oil rises with the increase of the well spacing density and saturation pressure, increasing with the decrease of the bottom hole flowing. Additionally, the effect of those factors is not obvious when the water is low in earlier days, the produced gas/oil ratio sudden increase with the water cut rises.
