As the ultra-heavy oil reservoirs developed by steam assisted gravity drainage(SAGD)in the Fengcheng oilfield,Xinjiang have problems such as huge steam usage,long preheating period,low production,and inaccessible reserve in local *** on the rock mechanics and porosity/permeability characteristics of heavy oil reservoir and interlayer,a series of true triaxial experiments and CT tests considering the fracturing fluid injection rate,viscosity,perforation density and location of fracture initiation were conducted to disclose the propagation behavior of micro-and macro-fractures in the reservoirs and mudstone *** experiments show that fracturing in the heavy oil reservoirs only generates microfractures that cannot break the *** contrast,when fracturing in the interlayer,the higher the injection rate(greater than 0.6 m^3/min),the lower the viscosity,the easier it is to form macro-fractures in the interlayers,and the further the fractures will propagate into the ***,increasing perforation density tends to create complex macro-fracture network in the interbedded reservoirs and mudstone *** findings of this study can provide scientific guidance for the selection of fracturing layer and the optimization of parameters in the interlayer fracturing of heavy oil reservoirs.

In order to analyze mechanism of casing damage,the uniaxial compression experiment and creep experiment of interbedded mudstone samples from Sanan development area of Daqing Oilfield under different water contents were carried *** changes of the mudstone’s mechanical parameters and creep characteristics with the increment of water saturation were *** results indicate that the rock strength and elastic modulus decrease rapidly with the increment of water content,at the same time,the creep strain and creep strain rate of steady state increase with the increment of water content,and also the steady state creep strain rate is enhanced with the increment of deviatoric *** the creep characteristic curves,a non-linear creep constitutive equation of mudstone considering the change of water contents is established,which will be used in future numerical analysis.
