薄层多层的模糊聚类分层法

Using the Fuzzy Cluster Analysis Method of Fuzzy Mathematics to Get Independly Layers Profiles

实施多层压裂分析的基础工作就是地层分层,适当分层能够指导符合实际地质情况的压裂设计。通常凭经验手工分层,但随机性比较大。由测井曲线并结合适当的模型可得到连续的地应力剖面、弹性模量和泊松比剖面、破裂压力剖面,在获得地层的连续力学特性以后,用模糊聚类方法可方便、快捷地将地层分层,能够减少分层时的主观性和繁琐性,从而保证了评价结果的准确性和可信性。

To conduct fracturing on reservoirs with multiple layers which are thin and different in in-situ stress , the foundation work is to get independly layers profiles. The effect is not sound to depend on experience only. After getting continuing profiles of in-situ stress , the elasticity module, the bossen ratio and the breakdown pressure, using the fuzzy cluster analysis method of fuzzy mathematics, we can get independly layers profiles straightly and accurately to ensure the veracity and creditability of the valuing result and to avoid randomicity and trouble.
