A Review of Imbibition Mechanism and Development of Low Permeability Reservoir
Abstract
Low permeability reservoir has low porosity and permeability, small pore radius, large capillary force and poor effect of conventional water injection development. The study shows that the imbibition is influenced by rock and fluid properties. It will play a guiding role in the development of low permeability reservoir by studying the mechanism and influencing factors of imbibition and mastering the influence of different factors on the imbibition recovery. Imbibition is also an important reason for fracturing fluid loss. It is of great significance to determine fracturing fluid volume and optimize reflux design to fully study the suction capacity and rate of the matrix.
