根据渗流力学原理 ,利用试油产量与压差之间的关系式 ,分析了大庆外围低渗透油田的几个开发区块的产能资料 ,建立了试油产能和油井稳定产能的定量关系 ,二者为线性 .并用所得到的关系式分别对葡萄花油层和扶杨油层油井的稳定产能进行了计算 .预测永乐油田葡萄花油层比采油指数为 0 .116,与实测比较 ,相对误差为 8.66% ,实例表明 ,此关系式可用于开发油田的产能评价和新区块的开发规划 .
According to the theory of seepage flow, the relationship between oil production and pressure drop is used to analyze the production capacity of several development blocks in the peripheral low permeability oilfield of Daqing. The quantitative relationship between oil production capacity and oil well stable production capacity is established. The linear relationship was obtained.The stability of Putaohua reservoir and Fuyang oil well was calculated respectively by using the relationship obtained.The predicted oil recovery ratio of Putaohua oil layer in Yongle Oilfield was 0.116 and the relative error was 8.66% The example shows that this relationship can be used to evaluate the production capacity of the oilfield and to develop the new block.
