Abstract
A method of optimizing well spacing for shale gas development is provided. It belongs to the technical field of hydrocarbon reservoir exploration and development. The method comprises: firstly verifying block area based on the explored geological structure; analyzing the connection situation of a shale reservoir, identifying the minimum developing area units; calculating the recoverable reserves of the units, confirming the candidate units; drilling representative shale cores and analyzing related physical properties; calculating seepage field and pressure field using unified multi-field, multi-flow-regime, and multi-scale mathematical models; calculating the effective recoverable area of each well; and arranging wells based on the rule that the interference among wells is not larger than 10%. Considering the fluid-solid coupling effects, the method can define appropriately well spacing for shale gas exploration and enhance effectively the output of shale gas.
