As an important follow-up strategic resource,shale gas is now explored and industrially produced in China,and obvious results have been obtained. However,the inexperience in evaluating the shale gas resources/reserves estimationleads to incorrectness,unreliability and even error in estimating geological and recoverable reserves of shale gas in the Regulation of shale gas resources/reserves estimation published on June 1,2014,which deserves more attention. The core of the regulation is to estimate the reserves of the shale gas,and great importance should be attached to insure its correctness in order to avoid mistake in evaluation results and even investment risk. The estimating method of the adsorption gas reserves in the shale gas reservoir,free gas reserves in fractural system are incorrect and the corresponding estimating method of the recoverable reserves is incorrect or even mistake. Moreover,using the initials of Chinese Pinyin x,y and z as subscript of different symbols is irrational,which doesn’t maintain the principle of using English professional terms as the subscript.Existing problems in estimating geological reserves and technical recoverable reserves of shale gas were analyzed. It is sug? gested to discuss about the estimating method of shale gas reserves and the scientificity and reasonability of its symbols. Also,rules of dynamic estimating methods and application case are recommended. Other methods,such as prediction model,may be introduced at the same time.
