摘　　要：塔河油田八区的主产层为碳酸盐岩裂缝-缝洞型储层,具有很强的非均质性,给储层的油气预测带来了一定的困难。应用传统的储层预测方法很难准确预测出油区内油藏的油水界面,从而很难弄清储层的分布、发育规律。针对塔河油田八区特殊的地质条件,采用了地震数据体结构特征法对该区奥陶系储层进行了油气预测,并对油区内、外的区域进行了有利区块的划分。在有利区块中设计的18口钻探井位,经钻井证实均获得了较高的油气产量,取得了很好的经济效益。The main pay-bed of the eighth zone in Tahe Oilfield is a carbonate fracture and fissure-carven type reservoir with very strong inhomogeneity, there are some difficulties of the hydrocarbon prediction. It is difficult to accurately predict the oil-water interface and discover the distribution and growth laws of the reservoir using the traditional reservoir prediction methods. In accordance with the special geological conditions of the zone, the method of seismic data structure characteristic was applied to hydrocarbon prediction for the Ordovician reservoir, and the division of the favorable block to the area in the oil zone and outside was carried out. 18 wells locations were designed in the favorable block and verified by the well drilling. These designed wells all have obtained high hydrocarbon production and good economic effect.
