摘要
本文利用取心井的少数储层孔隙度与测井数据,应用灰色系统理论,按照GM(O,N)建模方法,确定了川中磨溪气田香四储层孔隙度和测井数据间的量化关系,并预测了未取心井的储层孔隙度,其结果与回归方程和测井解释相比较,具有拟合、预测精度高等特点。
Using a few porosity and logging data of reservoir in core wells, applying gray system theory and according to the method for setting up a model with GM(O, N), this paper determines the quantity re- lation between the porosity and logging information in Xiang-4 reservoir of Moxi Gas Field in centre Sichuan and predicats the reservoir porosity in non-coring wells. Compared with regression equation and logging interpretation, its result has some characteristics such as high precision in matching and predication etc.
