Experimental study on sand control gravel particle
2022年11月1日 Gravel packing is an effective method for sand control. The median grain size ratio (D 50 / d 50) values and fine particle content of gravel pack are important factors in sand control during natural gas hydrate exploitation. This stone focuses on the sand blocking effect and permeability characteristics of different grades of gravel.
