Abstract: Through optimizing output and productivity, reasonable sand production exploitation decides optimal production measure between sand prevention and sand production. Reasonable sand production has big influence on physical properties of reservoir. In this paper, Bohai loose heavy oil reservoirs are taken as an example, some exploitation methods which improve the single well production with reasonable sanding are put forward, and corresponding experimental researches carried on. Based on investigation of simulating experiment about sand production at home and abroad, by using existed experiment device， man-made-cores are made，and laboratory research on the influence of proper sand production on formation physical property is conducted by using screen analysis and direct sand production. The researches are based on the proper sand production theory. The result can guide scientific production and administration in Bohai heavy oil reservoirs.
