蒸汽驱动态调控方法探讨

Approach to control methods of steam flooding performance

运用动态分析和数值模拟手段,从实现蒸汽驱操作条件的界限出发,提出了蒸汽驱不同阶段的动态调控方法:吞吐引效法、注采平衡法、驱替均匀法、注汽调整法、汽窜控关法。根据生产特征的变化规律,给出了这些方法的调控基准。该方法在齐40块蒸汽驱先导试验中应用后见到了显著效果,证实了该方法的可靠性和适用性。

Methods of steam flooding performance control are presented by means of dynamic analysis and numerical simulation by starting from the limits on steam flooding operation conditions,including huff and puff induction,in-jection-production balance,even displacement,injection steam adjustment,and steam channeling control.The adjusting and controlling benchmarks of these methods are given based on production performance.The remarkable result observed in the steam flooding pilot test in Block Qi 40 has verified the reliability and feasibility of these methods.
