中文摘要:
      以某油田油藏参数为基础,利用单管填砂管以及并联填砂管驱替实验装置开展了空气泡沫调驱体系的方案优选研究。通过单管和并联双管填砂管实验,考虑了不同影响因素对空气泡沫驱效果的影响。结果表明,单管实验中气液比为1:1时,注气速度为36mL/min时封堵效果最好;双管并联实验中,注入量为0.3PV以及注入段塞为弱空气泡沫+中等空气泡沫+强空气泡沫,且注入比例为5:3:2时,提高采收率幅度最大。
英文摘要:
      Based on the reservoir parameters of a certain oilfield, a pilot optimization of air foam flood control system was carried out by using single tube sand filling pipe and parallel filling pipe replacement experimental device. Through the single-tube and parallel double-tube sand filling tube experiment, considering the impact of different factors on the bubble effect of air. The results show that the best blocking effect is achieved when the gas-liquid ratio is 1: 1 in the single-tube experiment and the injection rate is 36mL / min. In the double-tube parallel experiment, the injection amount is 0.3PV and the injected slug is weak air bubble + Medium air foam + strong air foam, and the injection ratio of 5: 3: 2, the highest rate of enhanced recovery.
