通过大庆油田厚油层矿场试验研究，对储层流体流动单元问题进行了探讨。研究认为，对于储层描述来说，基于Ｌ．Ａ．Ｚａｄｅｎ复杂系统的“不相容原理”，随着沉积单元的变小，井间对比及砂体边界确定的难度将进一步增加，以致于无能为力。广场试验目的层葡Ｉ(１－４)共划分为３个时间岩性单元，细分为７个韵律段，１３个均质段。实际的油水井分时间岩性单元，韵律段、均质段测试资料以及指示剂验窜资料，有力说明了无论从油藏动态分析还是从油藏数值模拟角度出发，将时间岩性单元（即小层或单砂体）作为流体流动单元是基本可行的，进一步细分流动单元，试图实现“保砂体”模拟是很困难的。
Through the experimental research of Daqing Oilfield thick reservoir, the fluid flow unit in reservoir is discussed. The study suggests that, for reservoir description, it is based on L. A. Zaden complex system “incompatible principle ”, as the deposition unit becomes smaller, cross-well comparison and determination of the sand body boundary will further increase the difficulty, so powerless. The purpose of the plaza experiment Pu I (1-4) is divided into three time lithology units, subdivided into seven prosodic segments, 13 homogeneous segments. The actual oil and water well time lithologic unit, the rhythm section, the homogeneous section test data and the indicator channeling data provide a good example that the time lithologic unit (ie, Small layer or single sand body) is basically feasible as a fluid flow unit. It is very difficult to further subdivide the flow unit and try to achieve a “sand body” simulation.
