Embodiment Construction
[0115] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0116] Such as figure 1 As shown, it is a comprehensive method for automatically judging the connectivity between production wells in fractured-cavity reservoirs described in Embodiment 1 of the present invention, including the following steps:
[0117] Step 1. According to the production data of the well group to be judged, the production data of adjacent wells when the wells are switched on and off, the similarity of production curves, the time interval of water breakthrough and the pressure drop trend are used to judge the productivity of any two production wells in the well group to be judged. The initial connectivity between wells; wherein, the production data includes the liquid production rate and water conte...
