摘　　要：下二门油田北块浅层系H2I3小层为带气顶、油环及边水的特稠油油藏,先后采用边外注水开采、出砂冷采(用螺杆泵)以及蒸汽吞吐开发,取得了一定的开发效果。为进一步提高储量动用程度,采用数值模拟方法对不同开发方式及效果进行了预测,认为直接蒸汽驱效果优于继续蒸汽吞吐和间歇蒸汽驱,并对该层转蒸汽驱开发的技术可行性及效果进行了分析。Xiaermen oilfield north block shallow layer H 2Ⅰ3 layers is extra heavy oil reservoir with gas cap, oil ring and edge water. Out edge water flood, sand carrying cold production(by screw pump) and steam huff and puff have been applied, which obtained certain development effect. In order to improve the producing degree of reserves, using the numerical simulation method to predict different development way and the effect. It is thought that the direct steam flooding is superior to steam huff and puff and intermittent steam flooding. The converting steam flooding technology feasibility and effect were analyzed in the paper.
