Zusammenfassung:	The invention relates to the field of unconventional oil and gas exploration and development shale reservoir evaluation, in particular to a reservoir compressibility evaluation method suitable for a shale gas old area development adjusting well, which comprises the following steps: step 1, reservoir shale brittleness evaluation; step 2, collecting various compressibility related parameters of thereservoir under the original condition; step 3, developing and adjusting stratum pressure change analysis around the well; 4, developing and adjusting well stress field change analysis; 5, establishing a compressibility evaluation model of the development and adjustment well; and 6, evaluating the fracturing transformation effect obtained by the unfractured development adjusting well. The method can solve the problem that the prior art is only suitable for compressibility evaluation of a new block without influence of old well production and cannot provide guidance for subsequent fracturing construction of the old wel
