| 摘 要： | 为了改善注水开发效果差的情况，对无因次等孔隙体积配产配注理论改善注水开发效果的方法进行了研究。针对高30断块油藏，分别使用无因次等孔隙体积法和传统的kh值计算其合理配产配注量，接着采用油藏数值模拟进行了无因次等孔隙体积配产配注法和传统的kh法在该断块油藏注水开发的对比预测。结果表明，相比kh法，无因次等孔隙体积法使油田有效开发时间延长27年，采出程度由22．46％提高到27．94％，提高5．48％，增产原油19．88×10^4t。所以采用无因次等孔隙体积配产配注法比传统kh配产配注法更加符合油藏实际，使有效开发年限更长，最终水驱采收率更高。该方法可以为同类注水开发油藏的合理配产配注提供参考。

| Abstract: | Dimensionless pore volume technology has been used for improving the result of water injection. The dimensionless pore volume technology and traditional kh method were used to calculate the suitable production rate and injection rate in Gao 30 fault block oil reservoir. Meanwhile, through numerical simulation, the water flooding performance has been predicted by the two meth- ods. The results indicate that the dimensionless pore volume technology is better than the traditional kb method, with the effective production period prolonged by 27 years, oil recovery increased by 5.48%, from 22.46% to 27.94%, and 19.88×10^4 t additional oil might be increased. Compare with the traditional lda method, the forecast results with dimensionless pore volume technology is ac- corded with the actual reservoir conditions, extending the effective production year, and improving the final oil recovery. This method ean provide some references to calculate the suitable production and injection rate for the similar water flooded reservoirs. |
