Methods of natural gas reservoir identification and evaluation in Erdos Basin
鄂尔多斯盆地天然气有效储层识别与评价方法

A new method of normalization the logging datum for identification the effective reservoir using the information of logging and test is developed in order to solve some problems of exploration and development of gas in Erdos Basin. We also study a method to rebuild the characteristic curves of the effective gas reservoir with logging datum and introduced a new way to estimate gas reservoir production energy. The limitations of several techniques commonly used in evaluating the reservoir have been analyzed, and a new way to identify and evaluate gas reservoir is given mainly based on density log,neutron log and acoustic log , otherwise natural gamma log and spontaneous potential log used as restriction. Some well logging datum has been processed and interpreted by useing these methods.
