HM-819 多元驱油剂
产品特性
复合体系:由三元复合驱(碱+石油磺酸盐+聚丙烯酰胺)与水溶性催化降粘剂组成,兼具降粘+驱油双效。
超低界面张力:将油水界面张力降至 10⁻³ mN/m,高效启动剩余油。
微乳化作用:形成 W/O 或 O/W 乳液,兼具亲油性与亲水性。
润湿性改善:使岩石表面由亲油转为中间润湿,更利于驱油。
流度比改善:降低油水流度比,扩大波及体积,提高采收率。
安全环保:淡绿/淡蓝液体,密度0.96 g/ml,常温–220℃适用;无毒无味、不燃不爆、可降解、不含有机氯。
应用优势
采收率提升:较水驱提高20%以上,较聚合物驱提升约10%。
适应性强:适用于复杂油藏,尤其对中低渗透层效果显著。
非均质改善:缓解油层非均质性影响,驱油更均匀。
使用方法
配制方式:与水混合成微乳液,可通过高压泵吞吐注入或随注水持续驱油作业。
推荐用量:一般浓度约 0.8%;碱性驱时可加入 1–2% 纯碱,用量同样为0.8%左右。
Key Features
• Dual function: viscosity reduction + enhanced oil recovery.
• Ultra-low IFT: reduces oil–water interfacial tension to 10⁻³mN/m, mobilizing residual oil.
• Microemulsion effect: forms W/O or O/W emulsions, strong HLB balance.
• Wettability change: shifts rock surface from oil-wet to intermediate-wet.
• Safe & eco-friendly: non-toxic, odorless, non-flammable, biodegradable, chlorine-free; effective up to 220℃.
Advantages
• Recovery increase: +20% over water flooding, ~10% over polymer flooding.
• Strong adaptability: effective in complex reservoirs, especially medium–low permeability layers.
• Improves heterogeneity: enhances sweep efficiency and oil displacement uniformity.
Applications
1. Flooding operations -continuous injection with water.
2. Huff & puff -injected via high-pressure pump.
3. Dosage - 0.8%; in alkaline flooding, add 1–2% soda ash.
