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