Discussion on stimulation technology of shale gas reservior in Yanchang formation,Ordos basin

In reference to foreign marine facies shale rock gas reservoir transformation standard,combined with the features of Yanchang formation continental facies shale rock gas reservoir in Ordos basin,according to the three aspects discussion as shale rock gas reservoir transformation mode,oil increment mechanism and regional layer selection,a design plan of fracturing fluid system optimization,proppant optimization,construction parameters optimization,matching technology optimization scheme has been proposed in the paper,which gradually formed a set of suitable sliding water fracturing technology for extended group of continental facies shale rock gas reservoir,and has some field application on several shale gas wells in Yanchang oilfield,and obtain some understanding on reservoir reconstruction of Yanchang formation continental facies shale.
