| 摘 要： | 在渤海油田室内配方和先导性矿场试验研究基础上,利用化学驱油藏数值模拟软件FAPMS,优化设计了渤海油田J3井区块矿场试验的最佳注入程序及段塞大小,结果表明,通过对注入不同浓度的疏水缔合聚合物的前置段塞及主段塞和梯度式后续段塞的优化,采收率比未优化时明显提高。说明渤海油田应该高度重视聚合物驱的注入方式和段塞优化设计,进一步提高聚合物的技术经济效果。

| Abstract: | The optimum injection procedure and chemical slug size of the Hydrophobically Associating Polymer used in suizhong36 - 1 Bohai oilfield test and using the reservoir simulator fames. Results show that oil recovery based on the slug size and injection precedence of pilot tests has increased by 10%OOIP by the optimization of increasing the viscosity of the polymer system, using a small preflush polymer slug and following s gradient buffer. As a result, much attention should be paid to the injecting precedence and slug size in order to enhance the economic effects of the polymer flooding. |
