Abstract：The boundary well searching of the injection-production system is the foundation of the producing perform-ance and remaining reserve evaluation in the oilfield development and adjustment .Aiming at the case of discrete points with variable well spaces ,a new kind of blocked rows-columns method used to identify the boundary wells is presented in this pa-per based on the characteristic analysis of well patterns .On the basis of proper step calculation ,the overall boundary of the field is firstly identified by the using of a comprehensive rows and columns method .And the blocked identifying method is then applied to the subsets with complex concave boundary .The overall boundary and the subset boundary are then combined together .The abnormal boundary wells are finally treated separately in order to obtain an accurate field boundary .The algo-rithm can be effectively used to identify the convex and concave characteristic in a discrete point set with variable point spaces .The method has been implemented in the evaluation of the producing performance and the remaining reserve in 12 blocks in Lasaxing Oilfield ,which improves the efficiency of the boundary-well identification and assures the accuracy of the remaining reserve calculation and shows a good result .
