There are many kinds of faults in ribbon-shaped composite reservoirs

which affects the change of bottom hole pressure. The location of faults and wells make it more difficult to establish and solve the model of well test analysis. Therefore

it is urgent to establish a well testing analysis model with partially permeable faults and in any location of wells in ribbon-shaped reservoir. Based on the partial permeability of the fault and considering the properties of the fluid and the composite reservoir

the physical model and the mathematical model of the ribbon-shaped composite fault and reservoir are established respectively. And then

the Laplace space solution considering partial permeability fault is obtained by Fourier transform and Laplace transform. The pressure and pressure derivative curves are drawn. The characteristics and sensitivity of the typical curves and the influence of well location on the typical curves of well testing are analyzed. And the importance of considering the partial permeable of the faults and well location is fully explained. It is of great significance to the research on well test interpretation method for ribbon-shaped composite reservoirs with partially permeable faults.
