为了扩大塔河油田主体，在塔河外围建立一个新的建产阵地，对于奇西三维地震资料进行精细解释，应用振幅变化率技术、精细相干体技术、趋势面分析、模型正演等技术，深入研究该区储层发育模式，盖层条件及储盖组合，精确描述油气藏成藏机制。并通过分析塔河主体已发现岩溶圈闭的测井、地震资料的地球物理响应，总结发现地震“串珠状”反射、岩溶“残丘高”为油气成藏有利区带。据此，在塔河于奇西地区识别描述了三级圈闭18个，合计面积298.3km2。

In order to establish a new oilfield in Tahe, we interpreted the 3D seismic data of Yuqixi area. We also applied amplitude change rate technology, fine coherence technology, trend surface analysis, and forward modeling techniques to research the reservoir development model, cover conditions and reservoir-cap combination in the area. As a result, an accurate description of hydrocarbon accumulation mechanism was concluded. By analyzing karst traps logging data and geophysical data, we summarized the favorable condition of the accumulation. Accordingly, we identified 18 traps in this area with the total area of 298.3km2.
