Abstract: Aiming at the problems appears as the initial input generally present high production capacity,water content rising high,production decline rapidly in Hu 39 east block reservoir,applying bottom water coning mechanism,the research has been carried on,which shows that the practical fluid quantity is greater than the critical fluid production in most of the wells,causing the early water content,reducing oil recovery rate.Secondly Hu 39 east block reservoir with serious sanding,casing easy damage,through the perforating density and the sand production mechanism,we find some measures as protective casing and slow coning and sand control in order to achieve efficient development of the reservoir.
