Abstract：After four time infilling adjustments in SN Block of Daqing Oil Field,currently well density has reached 53 wells/km2.But some difficulties still remained,such as sand distribution relationship between wells is unclear,micro-relief structures between wells cannot be characterized,and so on.According to the special geological condition and actual data,multiple methods are adopted such as geological statistical association simulation,ant tracking method and 3D curvature properties to study in the oil-water transition zone in the test area.SP association simulation technique was optimized to identify one-meter thickness reservoir.Micro-relief structures between wells could be reflected by curvature properties and ant-tracking attribute jointing wells information can identify subtle fault features.Application of these multi-methods can identify micro-faults and micro-structures,and subtle reservoirs.
