以塔河油田主体区缝洞型油藏为研究对象，应用先进的蚂蚁追踪技术，实现了断裂内幕裂缝及低级序断层结构的 精细刻画。 通过裂缝发育程度与油气富集程度、水淹程度及注采关系的分析，认为裂缝发育相对较差的井区仍有较高的剩 余储量丰度，并明确了剩余油分布的潜力区。 该技术的应用取得了很好的地质效果，为油藏后期剩余油挖潜及开发调整提 供了依据，也为类似油藏的裂缝预测提供了借鉴。

Taking the fracture-vuggy reservoir in the main region of Tahe Oilfield as a study object， this paper uses the advanced ant tracking technology and realizesthe fine description of fracture and low-grade fault structure inside rupture. Through analyzing the fracture development， oil and gasenrichment， water flooding degree and injection-production relationship， it is thought that the area with relatively poor fracture development  still  has the high abundance of remaining reserves and the potential areas of remaining oil distribution are put forward. The application of this technology achieves very good geological effect， which can provide the basis for the later exploration of remaining oil and development adjustment，  also provide a reference of fracture prediction for similar reservoir.
