Test Theory And Equipment Development Of Crack - Porosity Media Flow Channel Coefficient

In order to put forward to exploration measures accurately to improve the complicated fractured reservoir development effect, the seepage law of the complex fractured reservoir must be identified. And the accurate calculation of the fluid interporosity flow coefficient between the fracture and the matrix is the basis of the study of complex fractured reservoir seepage law, which is very important for the complex fractured reservoir development.In this paper, based on the seepage theory of fractured reservoir, with the interporosity flow coefficient test theory and experiment method, and the corresponding interporosity flow coefficient test equipment development, the author mainly carried out the following research work and obtained the corresponding results:(1) According to the research about the double porosity media seepage theory and the related experiment research status quo, the author used the theory of related seepage mechanic of double porosity media, formed the experimental theory of the lab test fractured-porous dual media interporosity flow coefficient.(2)For the formation of the experimental theory of interporosity flow coefficient, this paper analyzed the difficulties of testing the interporosity flow coefficient under the condition of lab, and explored the methods of the various important parameters in the experiment.(3)According to the research theory and experiment method, this paper designed and worked out a set of complete system of fractured-porous dual media fluid interporosity flow coefficient test equipment, and tested the reliability of the equipment.(4)The experiment developed the fractured-porous dual media artificial core, and used the interporosity flow coefficient test equipment, tested the interporosity flow coefficient of two types of crack cores(the transverse slot and axial slot), calculated out the core shape factor and interporosity flow coefficient.(5)Compared with the predecessors’calculation method of the shape factor, this paper obtained the shape factor based on the experiments that were similar to some scholars research results, which showed that this experimental equipment can be used for fractured-porous media fluid interporosity flow coefficient test.
