摘要: 针对常规泡沫在延长组长6油藏条件下稳定性差的问题,研制了一种稳定性较好的泡沫凝胶体系,并对其进行了稳定性及封堵性能评价。优选了质量分数0.4%发泡剂FP388、0.3%聚合物AZ、0.3%交联剂T1、0.3%交联剂T2和0.3%稳泡剂CK2作为体系组分。泡沫凝胶稳定性评价实验结果表明,在温度80 ℃,矿化度10 000 mg/L的条件下,泡沫凝胶半衰期能够达到12 d,且在30 d内泡沫凝胶黏度处于较高水平并保持稳定。所制备的泡沫凝胶体系注入及成胶性能良好,能够对中高渗油藏形成有效封堵。

Abstract: Aiming at the bad stability performance of normal foam in the Yan Chang No.6 oil field, a high stability gel foam system was developed and then evaluated in the aspect of stability and plugging. Through comparison and selection, now the system is made up of 0.4% FP388 foam agent, 0.3% AZ polymer, 0.3% T1&T2 crosslinker, and 0.3% CK2 foam stabilizer. The stability experiment of gel foam indicate that the half life of gel foam is 12 d and the viscosity of gel foam can stay at a high level, also remains stable in 30 d under 80 ℃ and 10 000 mg/L mineralization degree environmental conditions. The foam gel system has good injection and gel forming properties and can effectively seal medium high permeability reservoir.
