SAGD (Steam Assistance Gravity Drive) opposite dual horizontal well

The utility model provides an SAGD (Steam Assistance Gravity Drive) opposite dual horizontal well, which comprises a steam injection well and a producing well arranged on the same vertical plane, wherein the steam injection well is located over the producing well, the steam injection well comprises a steam injection well vertical section and a steam injection well horizontal section which are arranged in succession, the producing well comprises a producing well vertical section and a producing well horizontal section which are arranged in succession, a certain interval is arranged between the steam injection well vertical section and the producing well vertical section, so that an inter-well area is formed, the steam injection well horizontal section and the producing well horizontal section are arranged in the inter-well area and extend in opposite directions, and the projections of the steam injection well horizontal section and the producing well horizontal section are superposed on the horizontal plane. The pressure difference of the opposite dual horizontal well disclosed by the utility model is uniform, preferential seepage channels cannot easily appear, the occurrence of the steam channeling phenomenon is prevented or retarded, and the oil production effect of the SAGD technology can be improved remarkably.
