Daqing oilfield has entered into a period of high water cut, using western block of north second area as an example, wells has been developed by using water flooding and chemical flooding, the history of wells is complicated, but the study area still contains a lot of residual oil. Now main purpose is to find and exploit the remaining oil. With the development of the computer technique, using the petrel software developed by Schlumberger, a three-dimensional geological model can be easily and quickly established to quantitatively characterize the reservoir. Through integrated use of geological, seismic and logging data, structural model and attribute model can be established to accurately describe space geological characteristics of the reservoir, which has an important guiding significance for development and adjustment of oil and gas reservoirs, to further enhance the recovery ratio of the remaining oil.%大庆油田已进入特高含水期，以北二西区为例，萨北开发区北二西东块先后采用水驱及化学驱，井史复杂，但研究区内仍含有大量的剩余油。现阶段开发与调整主要目的就是寻找剩余油，开采剩余油。随着计算机的发展，采用斯伦贝谢公司开发的petrel软件，这样就可以方便快捷的建立三维地质模型能够定量表征油藏。通过对地质、地震、测井等数据的综合运用，建立构造模型、属性模型，精细描述油藏空间地质特征，对油气藏的开发和调整具有重要的指导意义，从而进一步提高这部分剩余油的采收率。
