摘要
甘谷驿低渗透油藏注水开发过程中普遍存在油井含水上升快、递减率大、采收率低等问题。空气泡沫驱提高采收率技术将结合了空气驱和泡沫驱特点,具有调剖和调驱双重功效,克服了空气驱气窜的缺点。文章探讨了空气泡沫复合驱在甘谷驿低渗透油藏提高采收率技术的可行性,并结合唐80井区两个井组的先导试验应用研究,进一步深入研究分析研究了技术适应性。现场应用表明,空气泡沫复合驱具有明显提高产量、有效降低含水率特点,在低渗透油藏增产、提高储层动用程度方面具有良好的推广应用前景。
A pilot test of air-foam flooding EOR technology in low permeability reservoir has been studied in this paper. Air-Foam flooding combines air injection and foam injection advantages together. It integrates both functions of injection profile controlling and effective displacement. It can overcome the shortcomings of gas channeling in air injection. The field pilot test of air-foam has been carried out at two well groups in Tang 80 area. The results showed that production increased obviously, water cut decreased sharply. Then air-foam flooding is a promising EOR technique for low permeability reservoirs.
