摘要(Abstract)：
河南油田浅、薄层低品位稠油注蒸汽吞吐后,采收率只有15%左右,大量的剩余油资源尚未得到有效动用。针对这一现状,先后开展了细分吞吐,加密吞吐,间歇汽驱和水平裂缝辅助蒸汽驱先导试验和推广应用,使河南油田低品位稠油热采采收率由15%提高到了30%以上,为油田的稳产起到了重要作用。
After steam huff and puff in poor-quality heavy oil reservoir in Henan oilfield,recovery factor is around 15%.A large amount of remained oil has been not produced.Separate zone steam huff and puff,infilling steam huff and puff,intermittent steam drive and horizontal seam assisted steam drive pilot tests were conducted and industrialized,increasing recovery rate from 15% to over than 30%.Thus application has played significant role in production stability.
