A Block in Daqing Saltu Oilfield Study on well network reconstruction of stratigraphic system

A block in Daqing Saltu Oilfield has a large span of formation systems, permeability grade difference, prominent inter-formation conflicts, low degree control multi-directional water drive, injection and extraction well spacing thin differential layers, utilization, etc. In this regard, based on the existing network, study reconstruction system network is carried out area. Longitudinal subdivision layer system, narrowing mining span, X, Y, Z oil mixed mining, adjusted to X separate Y + mining; at same time, according nature objects, objects medium high layer. On plane optimizing spacing, original 250m was 175m area which eased development contradiction.
