单家寺特稠油油藏经过近二十年的吞吐开发进入了多轮次吞吐后期开发阶段,由于边底水的强侵入致使吞吐效果越来越差,严重影响了多轮次吞吐后期开发效果。因此在剩余油分布规律研究的基础上,研制了三效合一的复合驱油体系,提出了不稳定复合蒸汽驱技术,改善了多轮次吞吐后期的开发效果。

After nearly twenty years of throughput development, the single-house special heavy oil reservoir has entered the later stage of multi-cycle throughput. Due to the strong intrusion of edge water, the throughput is getting worse and worse, which affects seriously the later development of multi-cycle throughput effect. Therefore, based on the study of the remaining oil distribution, a three-effect composite flooding system was developed, and the unstable composite steam flooding technology was proposed to improve the later development of multi-cycle throughput.
