Objectives: Qinshui basin is one of main coalbed methane basins in China, where the studies on hydrogeology patterns are relative weak now, due to lack of data. This paper aims to discuss the hydrodynamic patterns and their influence on coalbed methane drainage in Qinshui basin.Method: Based on the former research results and analysis of coalbed methane (CBM) well performance data acquired in recent years in Shizhuang CBM block, this paper discussed firstly hydrodynamics study method through well performance data interpretation. The characteristics of hydrodynamics in Qinshui basin were then discussed and the knowledge about hydrodynamics in the basin were extended, and finally the types of hydrodynamics and their control on CBM development in different CBM blocks were analyzed in Qinshui Basin.Results: There are three types of regional hydrodynamics including the gravity driven flows, stagnant flows and compaction driven flows from the edge to the central of Qinshui basin. Gravity driven flows and stagnant flows are beneficial to coalbed methane development. As for compaction driven flows, however, is harmful to coalbed methane development since its high reservoir pressure leading to inefficient depressurization of CBM wells. Conclusions: Whatever the hydrodynamics type is gravity driven flows or compaction driven flows, the local converged area with good condition for preserving and draining has a favorite development result. In the process of CBM exploration and development in the future, in order to maximize production and benefits, the local converged area should be sweet spot of CBM development.
