| 摘 要： | 曙光油田超稠油油藏埋藏浅,油层纵向及平面上非均质性,汽窜干扰十分严重,且多数吞吐油井处于中高轮次吞吐阶段,油井周期递减加大.泡沫凝胶技术通过优选发泡剂、凝胶,氮气辅助形成泡沫凝胶体系,利用泡沫贾敏效应实现对油井的调剖,凝胶提高泡沫稳定性,泡沫能够扩大封堵范围,降低对油层的伤害；消泡后氮气可起到增能作用,现场应用后有效抑...

| Abstract: | Steam channeling is very serious for the shallowly deposited extra-heavy oil reservoir in Shuguang oilfield because of its longitudinal and vertical formation heterogeneity,and the oil production declines greatly in the later stage of cyclic steam stimulation for most oil wells.The foamed gel profile control technique is to utilize suitable foaming agent,gel and nitrogen to form the foamed gel system and realize profile control of oil reservoirs by Jamin effect of foam,the gel can improve foam stability,the... |
