Abstract
An experimental test method for dynamic imbibition capacity of shale is provided. The method includes the following steps: core preparation; physical parameter test of shale; experimental loading conditions are determined according to formation stress, formation temperature and hydraulic fracturing parameters; and a dynamic imbibition saturation is defined to characterize a dynamic imbibition amount. Various factors, such as fracturing fluid flow, formation confining pressure, formation temperature and fluid pressure, are used to obtain change rules of dynamic imbibition with time under different construction parameters in shale fracturing process.
