秦家屯构造受小宽断裂带控制发育,呈轴向北东的背斜-断鼻状形态.SN122井位于断块高部,为小型浅层、低产、低丰度油田.通过对其开发概况、产量变化规律以及含水变化规律分析明确随着生产井数增加,产油率呈上升趋势.结合水驱状况以及采收率评价,得出其采收率.最后,对该区块存在问题进行分析.

Qingutun structure develops the axial north east anticline fault nose shape,which is controlled by small wide fault zone. SN122 wells which locates in high block is a small shallow,low productivity and abundance oilfield. It is clear that with the number of producing wells increasing the output of this oilfield rises based on its development situation,the change rules of the production and water-cut. The EOR of this oilfield is obtained by combining water flooding status and recovery efficiency evaluation. The issues needed to be resolved in this block are described as well.
