| Abstract: | Oil group I and II of devonian in Hade oilfield is a deep thin sand reservoir in Hade oilfield which consists of two sub-layer reservoirs.The reservoir is about 4500m in depth and is 1~1.5m in thickness for each layer.The two-step horizontal well is used to recover petroleum in this thin reservoir.However,it is difficult to understand the pressure distribution in the two layers,and to assess the efficiency of water flooding.Hence,the numerical model is established and the history matching shows that the water cut and pressure calculated by the model are very close to the actual observed data.The model is used to calculate the distribution of remaining oil.Results show that the remaining oil is mainly controlled by micro tectonics and injection-production pattern.This will be helpful for us to optimize recovery scheme. |
