Experimental research on proppant embedment

A experimental research on proppant embedment in core was carried out by use of self-propelled proppant embedment test instrument based on API standards.Studied the effects of proppant embedment and regards of the influence of layer fraction.Studied embedment of different cores with different sanding concentrations and pressure.Through experiments it is indicated that the fracture width can be greatly reduced by proppant embedment;the smaller the sanding concentration and the softer of the core,the greater level of embedment is.
