Shut in Pressure Test and Methods of ...

After oil wells were fractured, Pressure restore well test data of low permeable oilfields cannot test the straight line segment of radial flow easily. This paper analyzes the bottom hole flow characteristics in the earlier period of pressure restore test in fractured wells. Earlier flow in bottom hole is fracture single direction flow. It constructs a method for calculating the time of closing wells and measuring pressure in fractured oil wells using earlier well data. The method has practical application value, which can guide production.
