摘　　要：针对适用于孤东六区稠油冷采条件的两亲聚合物强化泡沫驱油体系,研究了其稠油驱替和封堵调剖性能。结果表明,两亲聚合物能够显著改善泡沫体系的调驱性能,其贡献大于单一泡沫体系,能够有效封堵高渗层,显著提高低渗透层的稠油采收率。在水驱的基础上,最终的低渗透层稠油采收率提高51.1%,高、低渗透层的综合采收率达到63%。In the light of the amphiphilic polymer enhanced foam system being feasible to the conditions of the heavy oil cold recovery in Block 6 of Gudong Oilfield, the performances of the oil flooding, plugging and profile control are studied. The results show that the amphiphilic polymer can substantially improve the profile control and displacing performances of the foam system, and its contributions are higher than those of the unitary foam system. In detail, it can effectively block the high-permeability reservoirs and obviously enhance the heavy oil recovery of the low-permeability layers. On the basis of the water flooding, the ultimate oil recovery is enhanced by 51.1% for the low-permeability reservoirs and the integrated oil recovery of both high and low-permeability reservoirs is up to 63%.
