Abstract

After long-term water injection and erosion in water drive development reservoirs, the physical properties and seepage of the reservoir will change significantly, resulting in complex groundwater flooding laws and difficult adjustments to oilfield development. Based on the actual core data of inspection wells, this paper studies the changes in the physical properties and seepage characteristics of ultra-low permeability reservoirs after long-term water flooding and their effects on oilfield development. Growth, particle migration, and the illiteization of clastic rocks make the average porosity of the reservoir change little, the permeability declines greatly, the acid-sensitive minerals in the interstitial decrease, the water-sensitive and speed-sensitive minerals increase, and the relative permeability curve is medium the bleeding point shifts to the right, and the wettability changes to be hydrophilic.
